Well No.6 Emergency Repairs - PW094
REQUESTED ACTION
Staff is requesting the City Council add this item to the Consent Agenda to
authorize expenditure for repair of Well No.6 in an amount not to exceed
$25,000.
DISCUSSION
On Saturday, July 21, 2007, Well No.6, located at West 77m Street, suffered a
failure. The well is a "line shaft" type pumping system where a motor resides
above-ground and approximately 300 feet of shaft extends below the ground to a
pump impeller that draws water up the casing surrounding the shaft and transmits
it to the East Water Treatment Plant. The failure is due to the aquifer draw down
and the lack of necessary water table over the pump. A contractor was dispatched
to assess the problem today and determined the problem. Very preliminary
estimates are that repair costs are $25,000.00. Staff is working with the
Contractor to fix the well as soon as possible.
RECOMMENDA TION
Due to current weather conditions and heavy water usage, staff recommends that
the City Council approve the allocation of emergency funds for the repair of Well
No.6. in the amount not to exceed $25,000.
