RE PROPOSAL TO BEGIN PROJECT
PROJECT 1112100-152 TELEVISING SEWER LINES
Dear Board of Directors
Previously four large phases of televising projects were
completed over a four year period covering the majority of the
District' s sewer mains and the results of the televising have
become the foundation for determining the schedule for
maintenance and rehabilitation of the sewer system After the
four large projects the fourth of a series of small yearly
projects was authorized and is nearing completion
This project as shown in the 1996-97 Capital Improvement
Program is the fifth in the series of small yearly projects and
will achieve the following results
1 By limiting the televising to less than $10 000 per year the
project does not have to be bid The District can select
its own contractor which will be the contractor who was the
low bidder and completed the four large televising projects
This will provide continuity in record keeping and
efficiency in completing the work since the contractor is
familiar with the system
2 The District receives frequent calls from homeowners who
believe tree roots in the District' s main line are causing
stoppages in their laterals By having the televising
contractor working on a regular basis throughout the
District the contractor can easily include areas where there
is a potential dispute
3 Certain areas need to be re-televised to check the
structural condition of the pipe and to determine the
effectiveness of the root cutting and foaming
4 There are some areas that have not yet been televised and
these areas will be a part of the proposed small yearly
televising projects

5 The main focus of this project will be to compare the
current condition of the lines with that of the 1989
televising project and include the results in an Engineer' s
Report This will help determine whether significant
portions of the system need to be re-televised
The project appropriation as shown in the 1996-97 Capital
Improvement Program is as follows
Design $ 2 , 750
Televising Cost 6, 000
Inspection 3 , 750
Engineer' s Report 2, 500
Reserve 2 000
TOTAL $ 17 , 000
It is recommended the Board authorize the televising to be
completed for less than $6 000 and the Manager/District Engineer
to complete the design and inspection and Engineer' s Report at
the following hourly rates not to exceed $2 750 and $3 750, and
$2 500 respectively
Engineer $63 00/hr
Inspection $42 00/hr

PROJECT 1112100-152
TELEVISING SEWER LINES
The project is the continuation of the ongoing yearly "pick-up"
projects where it is proposed to begin rechecking areas that were
originally televised in 1989 under the first phase of the
District's televising program Certain areas of the first phase
where problems were encountered such as roots, multiple cracks or
longitudinal cracks will be re-televised to compare the 1989
condition versus the 1997 condition This will assist in
determining whether significant portions of the one million feet
of District main line previously televised will need to be re-
televised
Upon completion of the televising, an Engineer ' s Report will be
prepared that outlines the results of the comparison and
determines the need for future similar projects The areas to be
televised are included in the 1989 televising area which is shown
on the attached map
Recently the District adopted Ordinance No 26 which allows, in
accordance with State law, sewer projects up to $10 000 to be
completed without going to bid The televising portion of this
project is $6 000 and this will allow continued use of the
contractor who has completed the District ' s previous televising
projects
The design portion of the project encompasses preparing maps and
schedules for the contractor Preparing the maps includes
reviewing previous televising projects to determine areas where
re-televising is appropriate The previously used area and
manhole designation system will be reused Inspection consists
of monitoring the District' s cleaning forces schedule since the
District must clean the lines immediately prior to televising, as
well as being present during the televising operation The
televising cost is estimated at 12 , 200 feet of pipe at $0 49 per
foot
- 9 -
An estimate of the project costs is as follows
Design $ 2 750
Televising Cost 6, 000
Inspection 3 ,750
Engineer's Report 2 500
Reserve or Contingency 2 , 000
TOTAL $17 000

Capital Improvement Program
Fiscal Year 1996-97
+ Project 1112100-149/SINKING FUND
This is the second year that funds have been set aside for future replacement or reconstruction of sewer
lines as they reach life expectancy Setting aside funds for future use now will benefit from
compounding over time.
o Project 1112100-150/PUMP STATION ALARM SYSTEM UPDATE
The Districts existing radio-alarm system is reaching its life expectance Parts may be obtainable for the
radios but the alarm reporting system appears to be unsalvageable. The District Engineer has
recommended that bids include replacing the radios as an alternative, which I support. The use of a
radio-alarm system has great value and benefit. The main saving has been in reduced response time.
auto shut down of pumps when a problem has occurred, and a reduction in overflows when there has
been a failure. The construction cost appears reasonable as does the design and inspection fees.
o Project 1112100-151/SEWER LINE RECONSTRUCTION \ arious Locations
This .s the sixth allocation in a continuing program t0 yovide funding for maintenance of,e' -er 1-ne.s at
\arious locations. Tins s a maim tenance program and priorities are established from the data ai,d
analysis -eceit ed from -evious televising of the Distn_ts sewer lines Since -epairs are small in length
the a\erase cost per toot will be higher when compared to major replacement projects The engineers
estimate appears reasonable The design and inspection fees of S % and 9% respectit el' appea, to be
„.thin acceptable standards. The 130/0 contingence estimate is reasonable.
o Project 1112100-152/TELEVISING SEWER LINES
This is part of an ongoing program to insure that the Districts facilities are functioning properh The
District Engineer proposes to check lines that were televised approximateh eight \ears ago this will
provide significant information in which to draw assumptions regarding other portions of the Districts
facilities. The engineering fees are higher than normal projects but since this requires proper selection of
locations to be televised coupled with reviewing the tapes and report preparation. the\ seem acceptable.
The inclusion of the e icinity map was beneficial and appreciated
e Project 11121100-153/ROOT INTRUSION STUD)' Sct',cr Laterals
This is the first \-ear fo. .his program. It appears to be a ,oint effort between the District and the Citt to
provide a public son ice as well as helping to identift potential problemslconflicts. The Dis' ct and the

phase. Hopefull the public ill view this as a posl •t e step and that the in,orm,.tion can be used for
