New pool filter to save water, energy

LAWRENCEVILLE -- A planned pool filter upgrade at the Collins Hill Aquatic Center will save water and energy at the county facility.

The installation of a new regenerative-media pool filter system will use 90 percent less backwash water and could save as much as $25,000 on annual electricity costs, according to a news release.

"In addition to the power savings, we should also spend less on chemicals and fuels to heat and treat pool water," said Jim Cyrus, aquatics manager of Gwinnett's Parks and Recreation division.

The pool's current filters use about 1.3 million gallons of water a year for backwashing to clean out accumulated debris, Cyrus said. The new equipment includes a variable drive system that allows less electricity use during non-peak hours.

The Gwinnett County Board of Commissioners approved a $173,385 contract with the lowest of five bidders, Waterworks Atlanta, for the project. Funding will come from the special purpose local options sales tax. Installation is expected to be complete by September.

The Collins Hill Aquatic Center, located at 2200 Collins Hill Road north of Lawrenceville, features an indoor lap pool and outdoor leisure pool. It opened in 2000 and operates year-round.
