Bid specifications are being prepared and bid advertisement will be made
in January and February 1987, with the contract to be awarded in May and with
a construction start date of June. The length of construction will be
approximately one and one-half years.

The project consists of improvements and modifications to the existing
sewer treatment plant and the construction of additional facilities at a
downstream location. The combination of improvements and new facilities will
provide a hybrid lagoon process capable of meeting secondary treatment
standards.

The collection system is fairly good, but most lines are 50-70 years old
and many are undersized, with the exception of the downtown area, where mains
and service lines were replaced in 1985 as part of a downtown improvement
project.

Water - The water system in Oak Creek is owned and maintained by the Town
of Oak Creek. The municipality gets its water by diverting Oak Creek, which
contains water from Oak Creek Basin and Trout Creek water, diverted by means
of the Rich Ditch. A two-acre-foot settling pond, located two miles southwest
of town, provides pre-treatment and water collection. This water is
transmitted to the water treatment plant by 3,300 feet of 12-inch line.

Water treatment consists of flocculation, coagulation, sedimentation,
filtration, chlorination, and fluoridation. The plant is classified as "CO by
the Department of Health. Part of the treated water goes into a 200,000-
gallon concrete water storage tank, while the rest goes into the distribution
system.

Specifications are currently being prepared for construction of backwash
settling ponds, which will treat the water discharged from the treatment plant
during the filter bed cleaning process. These will be located below the
plant, within the town limits.

The water is distributed by gravity force, through about 10 miles of
mains, with the exception of Highland Addition, which is serviced by a small
hydropneumatic system.

The quality of water delivered by the system is generally good and
complies with State regulations, although during spring runoff, some problems
with turbidity may occur.

The distribution system has inadequate pipe loops, creating "dead zones";
undersized mains; old lines with high leakage losses; and valving inadequate
for proper maintenance and repair. Leaky plumbing fixtures in homes and the
practice of bleeding pipes during the winter also contribute to Oak Creek's
high water use average of 250 to 675 gallons per capita per day. A Dismuke and
Dismuke (now D and D Consultants, Inc.) water system report estimates that
this extraneous leakage accounts for 40-60 percent of the water flowing into
the system.

Electricity - The Town of Oak Creek owns and operates its own electric
distribution system; however, it has no generating facilities. Approximately
