This project provides funding for the Moat Renovation of Mary/Carson and Wolfe/Evelyn Water Plants. This project involves repairing the moats (overflow containment areas) by grading and
reshaping, developing effective erosion control on the slopes, and installing one sump pump at the Wolfe/Evelyn plant.
The Mary/Carson and Wolfe/Evelyn water plants are equipped with containment areas (moats) that surround the perimeter of the plants. The moats are designed to protect the surrounding
neighborhoods from flooding in the event of a tank failure or failure of tank water supply to shut off at the appropriate level. The moats at these two plants have eroded or have slumped over time
and need to be graded to re-establish suitable containment volume and structural integrity.
Construction of the project should be done in one year, for time and cost efficiency.
Project Evaluation and Analysis
The only alternative is to delay the project. However, in the event of an earthquake breaching the tanks, the moats will be unable to protect City and private structures from possible water damage.
Containment is necessary because water cannot be released into storm drains due to residual chlorination.
These tanks are below grade and are surrounded by dirt walls that have started to erode over time. This project repairs the overflow containment area by grading and reshaping the slopes and repairs
to a sump pump at the Wolfe-Evelyn plant. The use of a sump pump at both Mary-Carson and Wolfe-Evelyn will require a de-chlorination device prior to being discharged to the storm inlet.
Fiscal Impact
This project is funded by the Water Supply & Distribution Fund.
