The consumptive use shown by Table IV-l is for the treated water supply
requirements. The raw water requirements for a system can exceed the
treated water supply requirements considerably, depending on the source
of supply and many other factors.

The current source of supply is deep wells. Since this source of supply
does not have evaporation and seepage losses nor any treatment plant
losses, the amount of water which will be required for the treated water
supply is very similar to that amount taken from the wells. Once the system
is metered, the primary losses would be in the normal distribution system
from leakage, flushing, water main breaks, and metering. These system losses
may typically be in the range of 10 to 20% of total water used. Anticipating
that future conditions will require additional and other types of treatment
and additional and other sources of supply, we have used a total system loss
of 25% in order to project a conservative raw water requirement. Based on
this consideration, the annual raw water requirements would be as shown in the
following Table IV-2.

Depending on the future source of supply for raw water, a larger allowance
for losses and provision for lower deliveries may have to be considered. This
would be particularly applicable if the source of supply was surface water
where heavy evaporation and seepage occurs, such as where the raw water
supply is from reservoirs or ditches. Additionally, if delivery of raw
water varies on a year to year basis, sufficient raw water must be purchased
to assure that the minumum amount of raw water for treatment is available
each year.
