SUMMARY: The
Sleepy Hollow Steelhead Rearing Facility (Facility) has a large cooling tower
onsite for the purpose of reducing the temperature of the raw incoming river
water to acceptable levels for the rearing of rescued steelhead. Built in 2002,
the tower is in need of normal repair and maintenance to the internal and
external plastic panels that air and water pass over to create the evaporative
cooling of the water. Over time, these panels have become clogged with deposits
and damaged by sun and physical contact. The fan motor is also in need of
replacement due to moisture damage and wear. We have a replacement motor onsite
and the contractor will do the switch-out with a crane.
RECOMMENDATION: Authorize the General Manager to enter into an
agreement with Cooling Tower Technologies (CTT) for cooling tower repair
work for a not-to-exceed amount of $51,000 for materials and labor.
DISCUSSION: The
cooling tower was installed at the Facility in 2002. Minor to moderate repairs have
been done to the plumbing and fan components over the years, but the large
plastic panels and internal media and are now worn and in need of replacement
in order for the tower to effectively cool the river water to healthy levels
for steelhead rearing. Additionally, the motor is old and corroded and should
be replaced with an existing stand-by motor onsite. Staff hopes to have this work
completed before the start of the large intake retrofit project at the Facility
this summer through fall.
Staff contacted five California companies that reportedly
do this type of cooling tower work and received replies from three. CTT had the
lowest bid and also has familiarity with our Facility as they have done
previous repair work on the tower.
