The best time to place concrete during the hot summer is early in the morning. We’ve got the first of two lagoons laid down. The concrete lining of the lagoon required approximately 730 cubic yards and will be used as a sediment pond. During the process of turning lake water into drinking water, silt, sediment and other particulates are removed through filtration systems. Backwashing these filters pushes sludge to the lagoons where the sediment falls out and the clear water is decanted from the top. The clear water is returned to the reservoir.

Next up for the Bodell crew will be to install the lagoon pump station, inlet vaults, and outlet structures. Once these new additions are complete, they will allow management of the wash water so the facility can continue to deliver culinary water to the surrounding area.
