Water Treatment Plant
The City of Lawrenceville had utilized water wells in the Wabash River basin for the past century and performed no other treatment than feeding chemicals at the wells. While this worked in the past, nitrate levels in the water supply began to routinely exceed acceptable levels, and iron and manganese caused contaminated outbreaks in the system.
Our team evaluated and developed effective solutions to the City’s water problems such as constructing a conventional groundwater treatment plant to solve the iron and manganese issue. The high nitrate levels required advanced treatment techniques. With the help of the Illinois State Water Survey, our engineers quickly determined that the typical well screen design was the cause of the nitrate buildup. New wells, screened at the bottom instead of the top, were designed and installed. The result was four new water wells that have virtually no nitrates in the water.
