(Spirit Lake)-- The Spirit Lake City Council last (Tues.) evening awarded the low bid of slightly more than $2.1 million dollars for a project designed to keep zebra mussels from interfering with the city's water supply, which comes from Big Spirit Lake.

Mark Hardie, an engineer with the Howard R. Green Engineering firm which is designing the project, says the project will also consist of putting an additional intake line from the pumphouse out into the lake, along with other things...SL Raw Water Project01 

"We're putting in an additional 20 inch, or 18 inch intake line and a new line out about a thousand feet, and then an intake line to bring it into the raw water pump station, and we're doing some improvements inside the pump station. We're adding both intakes, we're adding a zebra mussel control system to prevent the intake from getting plugged in the future when zebra mussels kind of take root.  This injects a very small concentration of copper that zebra mussels don't like and repels them."

Hardie says it also involves putting in a new feeder line along Hill Avenue from the pump house to the water treatment plant...SL Raw Water Project02 

"And then we're doing some improvements from Hill into the treatment plant, kind of a back door new raw water intake line to help alleviate some bottlenecks we have in that intake line, and then a little bit of piping inside the plant to connect the connections all the way into the process."

The council awarded the bid following a public hearing last (Tues.) evening that drew no comment.

The project will be funded in part through what's known as the SRF program, a revolving loan fund program through the state.
