Water Wells and Water Main Replacement - Normal, IL
Over the last 12 years, Clark Dietz has become the Town’s trusted advisor and has designed several water infrastructure improvements, including the following:
Water Wells - Three water wells with various downhole mechanical problems have been abandoned and replaced with new and improved wells incorporating the following features:
- The wells are tied into the SCADA system which allows continuous water level monitoring and variable frequency drives for optimum operation and to avoid over pumping of the Town’s well field.
- The casings have been oversized to allow for a future liner to be installed if mechanical issues arise down the road.
- Two of the wells are constructed with stainless steel materials for longer periods between rehabilitation cycles.
- The well, discharge piping, electrical and controls equipment are housed inside a split-face masonry building.
Water Main Replacement – Over 45,000 feet of 8, 12, and 16-inch water main have been replaced over several projects to improve hydraulic capacity, reliability and water quality, including the following:
- Horizontal Directional Drilling (HDD) - HDD has been performed using ductile iron pipe below a historic wooden bridge, tree-lined cobblestone streets, and through customer’s backyards to minimize disturbance to the community. In addition, an 800 foot long, 30-inch directional bore was performed beneath a freeway.
- Rehabilitation - An additional 5,000 feet of unlined cast iron water main had the interior corrosion deposits (tubercles) removed and replaced with a protective cement mortar liner, which eliminated customer complaints of stained laundry and plugged plumbing fixtures caused by the brown/red water.
