C cc a ' o cn arc is LU uj :1 x 0 e EL " "ter Item II r Proposed OCSD Transfer of Fairview Trunk Sewer to CMSD Reason for Transfer Orange County Sanitation District (OCSD) is a "sanitation districts`, as opposed to a "sanitary district," and a sanitation district is a regional agency that owns Large trunk sewers, treatment plants, wastewater recycling facilities, and ocean outfall facilities, OCSD sewer lines are large (96" diameter) while a "sanitary district", which is a kcal sewer agency, owns small diameter sewers (8", 101 12", etc.) OCSD has found itself owning multiple small diameter sewers that have caused OCSD to own and operate small diameter cleaning equipment in addition to their large scale equipment. OCSD, therefore, desires to transfer the smaller sewers to the, local agencies in which they reside, OCSD and the Costa Mesa Sanitary District (CMSD) have to date entered into four phases of sewer line transfers. The proposed Fairview Trunk transfer would be Phase V. Development of the Home Manchu The proposed' development of the Home Ranch (bounded by South Coast Drive, Ikea, 405 Freeway, and Fairview Road) presented OCSD with the opportunity to transfer the Fairview Trunk to CMSD. OCSD has historically mandated that new development be sewered northerly to the Sunflower Trunk instead of southerly to the Gisler Red Hill Trunk due to, the possibility that future widening of the 405 freeway may cause abandonment of the Gisler Red Hill Trunk, Preliminary indications are the future widening of the 405 will not negatively impact the Gisler Red Hill Trunk, therefore, C,CSD is taking the position that sewering the Horne Ranch by the Fairview Trunk or the CMSD Ikea Trunk in a southerly direction is conditioned upon transfer of the q-1rioterting oul, rwnmuni 's deal°'t and'the environtnent 6); p ovi'd jt sot -•rulast nd,5?for a Fairview Trunk. Sewering in the northerly direction is expensive and requires a new pumping station. Special Conditions During the previous transfer (Phase IV), OCSD retained ownership of the portion of the sewers that lie under the 405 freeway as requested by CMSD. OCSD has stated the transfer of the Fairview Trunk will include the portion: under the 405 freeway. CMSD Directors have countered by requesting OCSID share in future repair costs should the portion under the 405 freeway collapse or sustain significant damage. OCSD has suggested that installing a liner inside the sewer might satisfy CIVISD's concerns. This item is still in discussion. The original construction plans for the Fairview Trunk call out for reinforcing to be added to the portion of the sewer under the 405 freeway, however, the reinforcing detail does not appear on the OCSD plans. OCSID did manage to retrieve this detail from the Caltrans set of relocation plans and CMSD Staff is currently reviewing the reinforcement detail. Benefits to CMSID Benefits to the CIVISID include- * Continuing the mutually beneficial and friendly relationship with OCSID. 0 Collection of connection charges and yearly fees from developments, connected directly to the Fairview Trunk, CMSD ordinances exempt developments connected directly to an OCSD trunk because CIVISID has no facilities involved and provides no cleaning or maintenance. Based on a build-out of approximately 1 million square feet in the Home Ranch development, an estimate of one-time CMSD connection charges is $40,000 and the on-going yearly fee is approximately $39,0001, Staff has not yet studied other existing and potential connections to the Fairview Trunk. Additional infrastructure helps spread CMS D capital and maintenance costs. OCSD states there have been no sanitary sewer overflows (SSOs) from the Fairview Trunk. Trotecting our community's heafth and the environ-Vient (5y provi�f-j,ng soi'idwaate and seyver coffection services. WWU).cms'dca.gov Risks to CMS,D • Additional sewers provide additional possibilities of SSOs. • As CM'SD Board and Staff are aware, the South Coast Drive sewer transferred to CMSD as part of Phase IV transfer is surrounded by partially compacted, moist, soil, including sandy areas that make reconstruction very difficult. District Staff is unsure of the soil conditions surrounding the Fairview Trunk. • Should there be a collapse or significant problem of the Fairview Trunk as it passes under the 405 freeway, the repair may be very costly. Ownership of the Fairview Trunk may cause additional monies to be contributed to the CMSD asset management fundl. Que Diligence Steps and Progress to Date Due diligence includes developing the cost to repair existing deficiencies and bringing the sewer up to industry standards. These steps include: • Review the 2004 and 2007 CCTV of the trunk as provided by OCSD to determine needed repairs. • Compare the 2004 and 2007 videos to determine whether deterioration is occurring, with specific attention given to the portion under the freeway. • Inspect the manhole interiors, • Consider the adequacy of the reinforcement method for the portion under the freeway, • Prepare an Engineer's Estimate of needed repairs and rehabilitation. • Additional due diligence steps include researching soil conditions, ground water levels, and development projects in and around the Fairview Trunk. • Interview agency staff and senior officials to ascertain experience and results of projects in Fairview Road, • Prepare a report summarizing the findings for Board of Directors consideration, Staff has not yet begun the above due diligence steps.

The debriefing of the soils/change order issue in the South Coast Drive sewer construction project job involves specific public works construction law that needs to be understood for background. OUR CONTRACTPROVISIONS Our contract provides as follows with respect to a Contractor's responsibility for conditions encountered: 24. CONTRACTOR'S Independent Investigation. No plea of ignorance of conditions that exist or that may hereafter exist, or of conditions or difficulties that may be encountered in the execution of the work under this Contract, as a result of failure to make the necessary independent examinations and investigations, and no plea of reliance on initial investigations or reports prepared by DISTRICT for purposes of letting this Contract out to bid, will be accepted as an excuse for any failure or omission on the part of the CONTRACTOR to fulfill in every detail all requirements of said Contract, specifications, and plans. Nor will such reasons be accepted as a basis for any claims whatsoever for extra compensation or for an extension of time except as provided in Section 5. THE LAW ON REPRESENTATION OF SOIL CONDITIONS IN TRENCHES Soils conditions are classic undisclosed conditions. In Condon-Johnson & Associates v. Sacramento Utility District, the Court of Appeal rendered an important decision regarding when a contractor can recover for extra, compensation after encountering subsurface conditions that differ from those disclosed in the bid documents, notwithstanding disclaimer language that attempts to shift responsibility to the bidder. Costa.Mesa Sanitary District "Lessons Learned"—Soil lssues, February 10,2012 Page 2 This case interpreted Public Contract Code Section 7104, which provides that when a local public entity has contracted for an excavation deeper than four feet, it must pay for the cost of a change order when the cost of performance is increased because the subsurface conditions at the jobsite differ materially from those "indicated" in the contract. The key to District liability arises from whether the District "indicated" conditions in the contract, or merely made information available. In Condon-Johnson, the contract did have information in the bid specification documents about subsurface conditions that had been encountered with test borings, but the contract provided general disclaimers that it was the contractor's responsibility to evaluate the jobsite and. make its own evaluation of subsurface conditions. The case turned on whether the district provided information to prospective bidders from which an inference might reasonably be drawn that actual conditions were represented as to what would be encountered at the jobsite. In this case, a mq*)o,rity of the court held that the boring information was represented as what would be encountered on the jobsite, and therefore, when different conditions were encountered, the contractor was entitled to a change order for additional compensation per 7104. This case now stands for the principle that if we are make an affirmative, representation of a soil condition we will not be able to disclaim liability, no matter bow clearly our disclaimer is written. TRE LAW ON POSSESSION OF IN FORMATJO�N THAT WAs NOT DfSCLOSED If we possess soils information,, and fail to disclose it, we will be liable if it results in extra costs to the contractor because of the failure to disclose, In Los, Angeles Unified School District v. Great American Insurance Company, the California Supreme Court established the definitive test for when a public entity will be liable for failure to provide information that leads to a contractor incurring additional costs in a public works job. For background, a public entity will generally be liable if it concealed information it had in its possession. from a bidder if it knew it would atTect the bid, This case establishes the law when it cannot be proven that the public entity concealed the information, but it can be proven that the information was in possession of the public entity and would have affected the bid, The test has now been definitively established that a public entity will be liable if it knew,but failed to disclose, material facts that would affect the contractor's bid or performance. The test is now as follows: Rather, we hold that a contractor on public works contract may be entitled to relief for a public entity's nondisclosure: in the following limited circurnstances, (1) the contractor submitted its bid or undertook to perform without material information that affected performance costs; (2) the public entity was in possession of the Hwper&Bums,LLP 1 453 South 0assell Street,orange,Ca1ifbraia92366 d Telephone(7W)771-7728 A Faesimfle(714)744-3350 I w%vtOmperbunis.coin Costa Mesa' anitary District "Lessons Learned"'—Soil Issues February 10,2012 Page 3 information and. was aware the contractor had no knowledge of, nor any reason to obtain, such information; (3) any contract specifications or other information furnished by the public entity to the contractor misled the contractor or did not put it on notice to inquire; and (4) the public entity failed to provide the relevant information. The Court also noted that affecting the test would be factors such as any positive warranties or disclaimers made by the public entity, what information was provided in the plans and specifications, the difficulty of detecting the condition in question, any time constraints imposed on bidders, and any unwarranted assumptions made by the contractor. The Court noted that a public entity will not be liable for failing to disclose a condition that a reasonable contractor would have found on its own, but,that a public entity would be liable based on the totality of the circumstances if the public entity should know that a responsible contractor would be unlikely to discover the condition, TOTAL AssuMPTION OF ALL RISK BY BIJ)DER/CONTRACTOR It may be possible to shift all liability to the bidder/contractor if we clearly did so in the bid specs and contract AND were not in possession of information putting us on notice of conditions that might affect the job. CONCLUSIONS I. We have imposed a duty on the contractor to investigate all conditions and. to assume liability for failure to investigate. 2. If we make a representation of soils conditions that are to be encountered, we are liable if the contractor relied on that representation and soil conditions turn, out differently, causing extra work, 3 If we are in possession of soil conditions that might affect bidding, but fail to disclose, we are liable for extra work. 4. We may still be able to make the contractor responsible for extra work caused by differing soil conditions if we provide in our specifications that District makes no representations as to soils conditions and bidders assume all risk. We should expect much higher bids if we did so. Alan R.

Benefits of CMS�D 1/1 Program The Costa Mesa Sanitary District spends approximately$25,000 per year plugging and sealing manhole covers in order to prevent surface water runoff from entering the sewer system. At the Sewer System Committee meeting on February 14, 2012, a request was made to list the benefits of this program. A list of the benefits is as follows: * WDR requirements include provisions for limiting 1/1 so the CMSD program satisfies this requirement. * Surface water runoff is not allowed in sanitary sewers and plugging and sealing helps towards reaching this goal. * Allows CMSD to stay under 2% rain ingress as preferred by OCSD. * Reduces risk of SSOs as surface water runoff is prevented from entering sewers and filling the system. * Reduces grit from entering system,which lessens sewer,cleaning and improves hydraulics. * Lessens strain on OCSD treatment plants. loo T M Ln M Ln: Lf) 4J' V, ---------- ---------- --------- ... .............. . . .......... ............. r Zn T M N V CU I cn Cc :N m �Qo ko Ln: ci .............. ------ .......... ---------- ------- ----4 -------------- :41 :01 iC3 E U 0 tn Ln 40 cu Qj kD LLJ (A 0 G C) m m 0: CC) :Z:CL C) -------------- ---------------- ---------------- ----------t-------- ,......r-..--------- ----------- --------- --- ----- ----------- IV M 0) o i i g C%J r4 M L6 Ln: %6 1�4 ............. .............. ............... ....... -------------- ----------- ------ C - ----- M!------ 0 W fv LA: => > Ln kD m Q) > 10 C6 o L-:"R 11 ;LL: r 0 ........... ---------- ..... r.. ....... tL Ln 00 CM 4n; ID bo: x 0 H C) N N u r4l 4n 'o Fo— i N t�, Bo M LO M x 100, C) a t-A 4--4 i V UL.: ------ ....... ----------- ------- .....------ r.4 00 r14 C,4 m c> �o tl� 00 cn cl) N M- Ln ,-q N m nt Ln 0 pl, oo e-q f-4 t-q V-4 T-4 r-I rA V-4 C14 N r4 r4 (.4 N r rn M M, m m m m r r, 10 0 --1 N In eq r"N I //* / CR C) m cai i o;% q c7 cs r c�a pp pp %%%%/i r. �•o C O i p G7 C7 C f C7 CY ,N N%t'V / { S�,7 N�t,�PN�Nii NS, tl t4 Nth' /„N r//ANN 4aV NNII C,w N�N'%/ �� N N //�/ N iN!41 �c�01,Eo a rw:n h ca co h �a ra�rlIm s �t ca ua ' cvf ( r / /% c4' N I N N rw N NY N Ni /iii e /e� /i N a i/o u'a m t,aa s*s ez`',sr h hI� as ml r0 rn m 35 CO a0 os cvles sn n u'31 c� / N Nir ��'e➢ �c� r / ii f i% % r raa,csciciuDh o ,.,im ",C)mmc°.�m. ... ��im %// ! nuam%% °nmr/,°c�a//iii u>�1 c,cSC /, I r 6 / %O //.C7 ///��/h•- OIC7�±1i 00,!d�4© Q Fk C7�L7 c�,81�"°Imcv `°v�mca°°n''mp 0C) c �{c 61H6{u�< i// N ; � cq�ch - c5in ua %//%%%% Nimcin cauS�acro rr u41c.

From: Rob Hamers, District Engineer Date: March 13, 2012 Subject: Oversight of Private Pumping Stations Surmmmar�r Private pumping stations have a high risk factor for causing sanitary sewer overflows (SSCs) and the proposed program described below provides an opportunity to work in a proactive manner to lessen the risk, similar to the Sewer lateral Assistance Program. Staff Recommendations The Committee approves recommend'isng to the Board of Directors the following oversight procedures fir private pumping stations. Analysis Although private property sewer overflows are not the responsibility of the Costa Mesa Sanitary District, the Board recognizes that eventually the Waste Discharge Requirements (WDR) may be modified to have public agencies regulate or work to prevent private property SSCs. Discussion along these lines occurred at a Sewer System Committee meetings and the Board' members present requested staff investigate the time involved and costs for creating such a program. The benefits of such a program are listed below: The CMSD currently has four persons (two employees and two contract Inspectors) who have experience and expertise in pumping station design and maintenance. Advice given by these persons will likely improve the maintenance standard's of the private pumping stations. Protecting our community's health and the environment 6ypio,oi,drxgj sofid,waste aradseroercof(ectioyt ser°a ces. ' (VW "ISdca.gc,v Sewer System Committee March 13, 2012 Page 2 of 3 The program could be achieved for no cost if all the work is performed by the two District employees familiar with, pumping stations (Maintenance Supervisor and one of the Maintenance Workers) Should the District ever be fined for sewer spill's, the program will assist in providing an affirmative defense to the WDR regulations. The program represents the District using its resources in a, proactive and positive manner in the community it serves. As envisioned by Staff, the program would consist of twice a year visits to the 26 private pumping stations shown in Exhibit A, with the visits coinciding with the property owner's maintenance visits or some other convenient arrangement. Because the pumping stations are private, the property owner's approval is required. In order to explain the program and entice the owner into obtaining District recommendations, Staff developed the enclosed flyer, attached hereto as Exhibit B. The District would most likely use the same maintenance chart for the private stations as it uses for its own stations, attached as Exhibit C. Strategic Plan Element & Goal This item: supports achieving Strategic Element No. 1, Sewer Infrastructure, and Strategic Goal No, 1.7, Pump Station Maintenance & Standardization Program. Legal Review So long as District personnel receive authorization from the property owner or property manager, legal hurdles are minimized, District Staff will be sure to make "recommendations" instead of "directives" or "demands". On the advice of District Counsel, staff may be required to obtain written approval from property owners before entering his/her property. Financial Review Staff estimates 2 to 4 hours per visit, including therein a follow up visit, letter writing, note taking, and filing. Should the District utilize its employees, there would be no additional cost to the District. If the District were to use! its contract inspectors at $64.50 per hour, a visit would result in a cost to the District from $129 to $258. It is possible the program would decrease overall District costs as the prevention of sewer overflows results in less District time for mobilizing forces, responding to the overflows, and reporting the incidents. The program will also benefit the environment. Public Notice Process Copies of this report are on file and will be included with the entire agenda packet for the March 13, 2012 Sewer System Collection meeting at District Headquarters and on District website. Sewer System Committee March 13, 2012 Page 3 of 3 Alternative Actions 1 , Develop a flyer and' recommendationis in writing and avoid the expense of meetings by mailing all materials twice a year. 2.

Philadelphia Street Ontario, CA 91761 18927 Hickory Creek Drive, Suite 140 Mokena, IL 60448 Subject: Green Plumbing and Mechanical Code Supplement Proposals PC-51 and PC-52 Dear Mr. Viola The undersigned California clean water associations, otherwise referred to as the Clean Water Summit Partners, is a coalition of statewide and regional organizations representing local public agencies, engaged in providing clean water services to their communities., Included in the Clean Water Summit Partners are the California Association of Sanitation Agencies, (CASA); the Bay Area Clean Water Agencies (BACWA); the Central Valley Clean Water Association (CVCWA), the Southern California Alliance of Publicly Owned Treatment Works (SCAP), whose collective members serve over 9O percent of the severed population of California, and the California Water Environment Association (CWFA) that includes over 9,000 individual members working in the water quality field within the State of California. Tri-TAC (wv,-wj,rjtag,nr-) also endorses the Clean Water SLunjuit Partners position, The purpose of this letter is to address a proposed addition to the Green Plumbing and Mechanical Code Supplement (Green Supplement), specifically Article 307,1 of PC-51 and PC-52. The article as currently proposed states "Food waste shall be collected for beneficial reuse or shall be disposed to the sanitary drainage system through a food waste grinder". Although some Publicly Owned Treatment Works (P'OTWs) who operate wastewater treatment plants may agree with the idea of diverting food waste from landfills for beneficial reuse purposes, California POTWs and most private sewer owners generally oppose using afood grinder or pulper as a means to direct additional food wastes to the sanitary sewer system. These added materials can create multiple problems such as debris settling, odor generation, and corrosive atmospheres in the private and publicly owned gravity sewer systems, particularly when less water is being discharged as the result of water conservation (a common green practice in many regions). They also can negatively impact wastewater treatment plants due to increases in treatment required to process the additional loading from the food waste. Since 2006, California POTWs and sanitary sewer system owners have been under an order from the State Water Resources Control Board (WDR 2006-0003) to have a sewer system maintenance plan that includes as one of its elements, a Fats, Oils, and Grease (FOG) control program. A basic provision of most FOG control February 28, 2012 Dave Viola, Director of Special Services JAPM0 Page 2 programs is the requirement to not put FOG, in any form, down the drain. The Clean Water Summit Partners' member agencies are currently engaged in continuing campaigns throughout the state to educate food service establishments and the general public to not put FOG or solid food waste down the drain. The logic behind. this campaign is that fats, oils, and grease stick to food; therefore, putting solid food waste into a food grinder invariably puts FOG down the drain. The proposed article advises that solid food waste be discharged to the sewer system, which is contrary to the basic provision of FOG control programs not only in California, but in the majority of programs throughout the United States.(Complete information on "R 2006-0003 is located at lit .8 Nv,)Araterboards.ca_ As IAPMO is likely aware, local wastewater, discharge regulations, or ordinances, constitute an essential component of environmental law and give municipal agencies the power to control operations at facilities within their jurisdictions, The ordinances, being authorized under the Clean Water Act or California Water Code, will supersede the regulations found in the Uniform Codes. Many wastewater ordinances prohibit the installation of food grinders in new food service establishments and may even require the removal of grinders in existing facilities. Some agencies take the additional step of issuing a permit that includes this prohibition to ensure there is an enforceable mechanism to compel compliance. Needless to say, agencies that have such a prohibition will have a conflict with the proposed article and would not like having the plumbing code, or even the Green �upplemvnt, lean in that direction. While one can argue that food waste may supplement methane production in the anaerobic digestion process used by POTWs to treat, residential sanitary waste streams, there are many problems associated with handling additional loading from commercial food service establishments through the sewer system. It is important to note that not all wastewater treatment plants have anaerobic digesters and are therefore poised to capture digester gas. Moreover, the additional solids loading from food waste to a conventional secondary treatment process, if introduced through the headworks, may require more energy to process in the secondary system than it can recover via production of digester gas. Additionally, solids, loading from a food grinder in a commercial establishment can quite easily contribute to flow restrictions or blockages that could lead to a sanitary sewer overflow (SSO). These overflows are such a critical public health matter and environmental concern that California now requires all sewer agencies to publicly report every SSO that occurs in. their system. Food wastes can also create sanitary sewer over-flows which are subject to direct fines from the State of California, possible fines and lawsuits from the United States E-riviromnental Protection Agency and citizen groups, respectively, if overflows reach applicable federal waterbodies. Another major concern is the operational costs of cleaning the FOG and. solids from the sewer lines to ensure adequate hydraulic capacity to carry the sanitary waste which is, after all, the number one priority of the sewer system. Due to these concerns, the associated wastewater agencies 'would like to endorse the alternative wording suggested by the Orange County Sanitation District which modifies 55-PCI andlor 55-PC2 Article 307.1 as follows., Food waste shall be collected for benqficial reuse such (is composting or vertu culture, direct discharge to an anaerobic digester, or conversion to livestockfted. If a grinder orpulper is February 28, 2012 Dave Viola, Director of Special Services IAPMO Page 3 used to process the fbod waste at the collection site before its transfer to the point of reuse, then the effluent ftom such device must be strained to prevent./bod solids or particles from entering the sei4,ersysten?, Such a. modification allows for an on-site grinder or pulper to precondition the food wastes if a municipality wishes to have that as an option, but also protects the sewer system from the food solids loading. The strainer also protects the hydraulic capacity of a downstrearn grease interceptor if an establishment is so equipped. This approach continues to promote green reuse of food waste for agriculture or energy generation without negatively impacting the public sewer system. The Clean Water Summit Partners wish to thank TAPMO for prornoting public health, safety, and welfare through the development and promotion of the Unffiorrn Codes and Green Supplement, and for consideration of our concerns regarding this food disposal issue.

Thank you Tim Page-Bottorff for forwarding to rune, sewage treatment plant operator has been ordered to serve time in federal prison for not operating the facility at Niota, Tn., correctly and , for lying to state inspectors about it.Judge Sandy Mattice on Monday morning sentenced Donald Jack Clark to six months in International, i p rison and another six months of home E.irP,,vra��re�wrq�l #.g a�Pottlre �wF�r,�^ confinement with an electronic monitoring device. He must also perform 150 hours of community service. Prosecutor Matthew Morris had argued for a stiffer sentence, saying a message needed to be sent to other sewage plant operators not to endanger the public's health. He said there was no evidence that anyone became ill due to the problems at the Niota plant, but he said the possibility was there. Environmental inspector Angela Young of the Tennessee Department of Environment and Conservation said the effluent at the plant was not treated with chlorine for a two-year period. She said there was no evidence that the sewage sludge was being hauled away as it should have been. She said the chlorine is necessary to kill a coli and other harmful substances in the water. Ms.Young said the plant is on the tiny stream of Little North Mouse.Creek. She said there had'. been complaints that the creek had a dark color. The witness said Clark had reached the level of a class Ill operator and the state relied on him being honest in his reports. She said another operator at the plant turned in reports saying the plant was not meeting standards. Clark told the fudge, 1 made a terrible mistake." He operated the Niota plant in McMinn County for 17 years. Print Article: O.C.sewage spill costly fbr water district littp;i/www,ocregister,com/commot-Vprinter/view.plip'?db=ocprint&id=I 58696 O.C. sewage spill costly for water district 2012-02-19,WOO:00 RANCHO SANTA MARGARITA A decision is expected next month an a plan to relocate a Santa Margarita Water District pipeline,that ruptured in 2010, sending nearly 2.3 million gallons of untreated sewage into three south Orange County creeks, some of which made it to the Pacific Ocean. The spill was one of the five largest in Orange County in the past decade, according to state and County records. It forced the closure of a stretch of Dana Point coastline for six days, and has so far cost the district $2.3 million in repairs,fines and environmental mitigation efforts, Another$1.3 million has been set aside to relocate the pipe, which runs under Tijeras Creek near a sports park. The realignment of the pipe is part of a settlement agreement between SMWD and the San Diego Regional Water Quality Control Board, which governs south Orange County, The board determined the spill violated regional, state and federal regulations. An initial fine of$1.73 million was proposed, based on factors such as how much sewage spilled, the potential for harm to the environment and history of violations.The amount was reduced to$890,000 after the district provided the results of its investigation. Half of the fine was paid into a state cleanup fund. The rest is going toward an environmental project and the pipeline relocation. For the environmental:project, SMWD is spending $140,000 to support the removal of invasive artichoke thistle, and restoration of coastal sage scrub and native grassland habitats in Sell Canyon at the Audubon Starr Ranch Sanctuary,work that must be completed by October, according to the settlement. The remaining$305,000 must go toward the pipeline relocation,which depending on the alignment has an estimated cost of$900,000 to$2.3 million.The money is coming from the district's capital replacement reserves, a fund replenished annually to cover infrastructure replacement and emergencies. Water rates won't be affected, SMWD Chief Engineer Dan Ferons said, THE SP'ILL Wastewater travels to treatment plants,under force of gravity.Along the way, lift stations pump the sewage through pressurized force mains to pipes on higher ground so,it can continue on its way, again by gravity. Just after 4 p.m, on March 23, 2010, an alarm alerted a district employee to a pressure problem at the Piano Lift Station on Antonio Parkway.The leak was discovered !in a 24-inch diameter force main that runs from the station, under Tijeras Creek and up to another set of pipes heading to the Ch,iquita treatment plant-The leak was in a portion of the force main going up the east side of the creek. SMWD called other agencies and four commercial pumping companies for help. Sewage upstream from the spill was diverted to other treatment facilities or intercepted and pumped into other sewer systems. County workers built a berm to contain the spill,though about 870,0010 gallons is estimated by water quality officials to have reached the beach. Crews worked in 12-hour shifts to minimize flow to the station, repair the break and prevent more sewage from reaching the ocean. By 8 a.m. March 27, the pipe was repaired, and final cleanup began. Sewage trapped by the county berm continued to be pumped back into the sewer system for three more days. THE DAMAGE When engineers examined the 7-foot section of pipe removed during the repair, they discovered something unusual. The 21-year-old pipe, which has a 50-year life, had eroded from the inside out, according to a report by V&A Engineering, 2 of 3 2127/2012 9:41 AM Print Article: 0,C sewage spill costly for water district http://wwwocregister.con-Veoimmoil/priiiter/view.plip?dboeprint&id=l 58696 Small rocks, pennies, nails and screws that should have been pumped up and out of the force main weren't. Instead, they were being forced up and down the pipe by the lift-station pumps. They had been abrading the pipe's lining for some time,which peeled away, exposing the metal to further abrasion and corrosion from the wastewater.The result: a 69-inch long perforation and a massive sewage spill. The break was atypical, according to Jeremy Haas,environmental program manager for the San Diego board. The agency usually sees situations where pipes near creeks break because they were exposed from erosion by storm runoff, Haas said. The impact to the environment appears to have been minimal, according to several post-spill reports. Contaminants that spiked in the creeks during the spill dropped significantly within two weeks, and the groundwater system was not affected. The most damage was to the slopes and habitats by the station where the pipeline was excavated and repaired, and at the berm, That damage is being reduced and monitoring is ongoing. The water quality board cut the fine in half after SMWD showed the berm minimized much greater harm:to downstream waters, and that the district could not have reasonably expected the pipe to be corroding from the inside since it was well Within its life expectancy. THE FIX The district is iooWng at three,alternatives to relocate the force main, Ferons said, The first would be to run the pipe down Antonio Parkway, attach it to an existing roadway bridge, run it northeast next to Cahada Vista Park and reconnect it with the existing force main. The second and third options involve a suspension or pedestrian bridge over the creek,to which the force main would be attached The district has discussed the options with officials from the county,the city and the city's largest homeowners association, all of which have land that will be affected, Ferons said.The next steps include preliminary environmental analysis of the options,selecting one and preparing final design plans, and bidding and constructing the project, which must be completed by October 2013.
