MEMORANDUM 13-047

TO:  Walt Wrede, City Manager

FROM: Carey Meyer, Public Works Director

DATE:  April 3, 2013

RE:  Water Treatment Plant Redwood Tank Removal
  Demolition Funding Authorization
__________________________________________________________________________________

The redwood tank at the water treatment plant was built in 1974. It was built at the same time the old water treatment plant was built. The redwood tank is leaking, requires substantial maintenance, and may be creating water quality concerns due to the woods potential for harboring organic sediments. 

Additional storage tanks have been built at the water treatment plant site (a 250,000 gallon tank and a 1.0 million gallon tank).  The loss of the storage capacity provided by the redwood tank will not adversely impact the City’s ability to deliver water to its customers. Elimination of this tank will reduce the potential for the creation of disinfection byproducts by decreasing storage volume and chlorine contact time before water is delivered to the distribution system.

The City Council approved the acceptance of an EPA grant, a portion of which is being used to prepare demolition bid documents. The grant is for design efforts only. The demolition project is expected to be ready for bidding early this summer.

Recommendations:  The City Council pass an ordinance amending the 2013 operating budget authorizing the funding of demolition of the redwood tank demolition using Water Reserve Fund monies.
