Item XIV
1. Developing five quadrants, combining' /2 biennials + triennials to create annual and biennial cleaning totals
average required cleaning per year 703,400
2. 20 PS inspected once a day five times a week = 100 a week times 52 weeks = 5,200 inspections
3. Goal is to plug and seal 1,008 out of 4,705 manholes. Currently 802 manholes are plugged and sealed.
4. Elden, Harbor and Irvine pump stations cleaned once a year. All other pump stations cleaned twice a year.
5. 58 hotspot locations that had cleaning frequencies raging from twice a year to four times a year.
6. The average SLAP applications approved in five years (2007 -2012) is 157 x 2 = 314
7. One tailgate meeting a month.
8.
9. Total hours include the entire maintenance division (4 employees). Actual hours from FY11 -12.
10. 1.5 hours to test each equipment (4 generators and 3 by pas pumps) per month = 10.5 hours x 12 = 126 hours.
One hour to test each trash pump (2 4" trash pumps) six times a year = 12 hours
126 +12 =138 hours
* *Cost efficiencies for maintaining sewer mainline and pump station do not include contractor costs. Objective costs are
strictly staff driven.
