PROPOSED PROJECT (RECOMMENDED ALTERNATIVE)
******************************************************

, After acknowledging all aspects of the various' Alternates evaluated in the
Planning Document, the Board of Directors of the Pinewood Springs, Water
District, at ~eir meeting on July 23,2003, unanimously chose what is des-
. cribed in the Document as "Crow Lane #1" with aJ5' high dam, as the pre-
. ferred Alternate. This option, in the final analysis, offered the lowest cost per
. acre/foot of reservoir storage.

ter with the existing infiltration' gallery conveying raw water from the River
to the existing and adjacent treatment Plant, located at Cree Court and the ,.'

2) Treatment

The new treatment unit for this project will be equal to a Memcor Model
6MI0-C micro-filtration system as manufactured by the U.S. Filter Com-
pany, of identical capacity to the existing unit, with the following produc-
tion rates:

Average SUID.Irierproduction > 15 degrees Centigrade-36 gallons per minute

Peak summer production> 15 degrees Centigrade------40 gallons per minute

Average winter production> 1 degree Centigraq.e---32 gallons per minute

Peak winter production> 1 degree Centigrade-----36 gallons per minute

These production rates are net rates for the unit, after reasonable allowance'
for routine air 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 membranes, a
. Clean-in-Place (CIP) backwash is required consisting of alternating doses of
