Procuring Conventional Water Treatment Solution Utilizing an Unconventional Method

In 2001, the Slinger, WI,  Village Board wanted to provide their citizens with better drinking water by installing an iron removal plant to remove the 1.6 parts per million (ppm) of iron in its well water supply.  They had been using a sequestering agent to control the iron, but felt that removal was a better solution, as it would reduce the frequency of flushing the mains and provide rust-free water to residents.

The Village decided on a coached design-build approach to allow the involvement of all parties, reduce design and construction time, and reduce overall costs.

Once the pilot study was complete, the design-build team selected Siemens to supply major process equipment.  Since startup, the iron and manganese removal system has exceeded the village’s expectations, consistently reducing influent iron from 1.6 ppm to less than 0.1 ppm.  The village water supply is free of rust, and the flushing frequency for the distribution mains has been reduced, saving the village money on operating costs.  A single operator spends approximately one hour per month on routine plant maintenance.
