Proposed Action.
Staff recommends adoption of the following motion: Move that Council approve plans
and authorize bids for the renovation of water treatment plant #4 . Proiect 99-08.
Overview.
The Elmo Park water treatment plant filters were installed almost 35 years ago and are
in need of renovation. The city's capital improvement plan (CIP) includes a year 2000
water plant renovation project. In August, 1999 City Council authorized design of this
project through an engineering services agreement with SEH - ReM. Project design is
now complete and are presented to Council for approval and ordering of bids.

Analvsis of Issues.
. Description of Improvements
Renovation includes: removal and replacement of the water filter media (sand and
gravel) and the filter underdrain system; installation of a air wash blower and diffuser
system; and installation of a new backwash water supply pump.
. Engineer's Construction cost estimate
The engineer estimates the construction cost at $541,100.
. Project funding
The project will be funded from water utility funds. The cost of this project and the two
water tank painting projects has increased from $1.40 mlllion in the current CIP to 1.88
million for the three projects. Accordingly, the Finance Department will sell bonds in the
increased amount of $2.25 million in March, 2000. The $2.25 million covers not only
these three projects but also the next two years of radio read water meter installation.
The projected water rate increases to cover the revised water utility costs are: 1/112000
- $0.10 increase to $1.20/1000 gallons (previously approved by Council); 1/112004-
$0.20 increase to $1.40/1000 gallons; and 1/1/2010 - $0.10 increase to $1 .50.
