REHABILITATION OF FOOTHILL RESERVOIR
RECOMMENDATIQN:
That the City Council, at their regular meeting of November 6, 1989, authorize staff
to solicit bids for the installation of a fabric-reinforced Hypalon liner in the City°s
Foothill Reservoir.
BACKGROUND:
Foothill Reservoir, a 3.5 million gallon storage facility, is located in the
unincorporated county area at the intersection of Hewes and Fowler Avenues.
The facility was constructed by Tustin Water Works in 1959. Recent inspections
indicated root damage and a need to rehabilitate the gunite liner.
The Engineering Consulting firm of Woodside-Kubota was retained to study the
condition of the reservoir and prepare detailed recommendations on modifications and
repairs aimed at extending the life of the facility and maintaining acceptable water
quality standards.
The engineers recommendations have been held in ebeyance pending cool weather and
diminished seasonal water demands.
A Hypalon liner together with modifications to the over-flow piping are
recommended. It is proposed that repairs and modifications be made during the
winter months when the water d'i~mands are minimal.
The Water Capital Improvement budget provides for the proposed repairs and
modifications.
