Recommendations. The need and feasibility of
increasing raw water storage will be evaluated later
in this report. Even if capacity is adequate, the
operational problems need to be resolved. Low cost
improvements which could be made are:

1) Connect the headgate pipe to the reservoir bypass
pipe, to allow taking the reservoir out of
operation.

2) Rebuild the catwalk at the outlet pipe.

3) Divert irrigation water through the reservoir and
then back to Gurley Ditch to prevent stagnation.

4) Deepen the reservoir to reduce weed growth.

OTHER WATER SUPPLY FACILITIES

1. Water Treatment.

The existing water treatment plant includes the
following treatment processes:

a. Two 72 inch diameter pressure clarifiers. These
are closed steel tan~s with a coarse filter media
which functions similar to a flocculation tank and
settling tank combined. They were installed new
in 1987.

b. Two dual media gravity filters with dimensions of
5 ft. x 8 ft.

c. Chemical Feed System. This consists of an alum
solution feed system and a polymer solution feed
system. Both are used as coagulants for removing
turbidity. There are also facilities for feeding
soda ash and fluoride.

d. Chlorinator. After filtration, the water is
disinfected using a gas chlorination system.
consists of a cylinder mounted chlorine feed
and a recirculation pump with an ejector.

All piping is Schedule 40 PVC. The plant has master
meters. The filters haves an automatic backwash
cycle. The pressure clarifiers also have automatic
backwash cycles.
