-These production rates are net rates for the unit, after reasonable allowance
for routine 'ail; backwash, so that the 24. hour. production rate for any of the
conditions indicated is the above related gpm multiplied by. 1440.

Periodically, depending on the head loss across the filter membran~s, a Clean- .
In-Place (CIP) baclcwash is required which consists of a sequence of prepared
doses of low pH followe4by high pH water delivered to the membranes.The
waste from this CIP is conveyed to a neutraIization tank where it is treated, if
' necessary, to attain the appropriate pH for discharge to an adjacent percolation
p6n~ and there is no discharge of any 'sort to tqe River.' . ..'

Positive displacement chemical feed facilities deliver caustic soda and hypo-
. chlorite solutions to the water for pH control and disinfection, respectively,
before it is delivered to a clear well for the frrststage of high service pumping.

2) Distribution and Storage

As mentioned earlier, the existing distribution system is intended only for.
. domestic flow, and for the most part consists of 1-1/2" and 2" piping with
some small amounts of 3", 4" and 6", with polyethylene being found as the
most widely used material. .

There are three pressure zones in the distribution system in order to cover a
600' range in elevation in the District's service area.Exhibit "E" is a schematic
of the three zones,' indicating the pump stations and storage capacity for each
zone, as well as the elevations at each station, and the elevations at the high
water level in the storage, tanks.

After treatment, the water is delivered to a clear well, from which it is pump.;.
ed to low zone storage consisting of a ground level! 00,000 gallon tank adjac-
ent to a 500,000 gallon tank located at the east ~nd of Navajo Ct.

A pump station at May Avenue and Kiowa pumps the water from the low zone
to a buried 20,000 gallon tank serving the mid-zone and located on Pinewood
Drive approximately 0.3 of a mile west of Highway 36.
