Diagram courtesy of Hayden Area Regional Sewer Board This diagram illustrates how the Hayden Area Regional Sewer Board will perform smoke testing Monday through Aug. 18 of its sewer lines to meet water quality standards.

The testing will be done in the Lock Haven area and various locations of the Hayden Lake Recreation Water and Sewer District (HLRWSD) to allow the board to find where leaks are in the system.

HARSB, which along with the cities of Coeur d'Alene and Post Falls discharge treated wastewater to the Spokane River, will be installing membranes to remove phosphorous from the water and meet water quality mandates.

"Until we understand where and what the leaks are, it is not possible to estimate repair costs," said Ken Windram, of HARSB. "But what we spend on leak repairs will reduce membrane purchase costs along with the operation and maintenance cost to treat rain water at the treatment plant." Full story. Brian Walker/CdaPress
