04-01: Denver's Cooling Tower Water Conservation Program

The Denver Water Board has initiated a cooling tower water audit program. The purpose of this program is to identify if and to what extent water conservation is possible through optimizing cooling tower system operation. This paper provides the results of these audits to date. It includes the water savings that have been identified along with specific data on water quality that could be maintained. Over 700 cooling towers could be involved to help reduce Denver's drought condition. There will also be a brief review of the Denver Water Board's time schedule for water rate increases and their overall program for water conservation.
