With an conservative eye, the IIW environmental engineering team completed an overhaul of Leisure Lake’s Wastewater Treatment Facility that reduced project costs and delivered long-time energy savings.
IIW’s engineers replaced more than 400 on-site septic systems with a three-cell controlled discharge lagoon with a synthetic liner.
Rugged topography and excessive costs of conventional sanitary sewer collection system posed challenges. To overcome them, IIW employed individual grinder pumping stations with small diameter pressure fed forcemains. This reduced the cost to the project significantly and provided lower energy costs to the utility.
