Macon Municipal Utilities (MMU) supplies water to the City of Macon, Missouri and local rural water districts in the area. Over the last several years, the high service pumps were experiencing erosion damage due to cavitation leading to increased maintenance costs, reduction in pump performance, and excessive down time.
Benton and Associates was selected to evaluate the pump station and provide new solutions to a long standing problem. Detailed testing and hydraulic analysis was conducted to determine pumping deficiencies and best efficiency points for a number of operating scenarios. Numerous short comings were identified with suction/inlet piping geometry, sizing, and arrangement which was the primary cause of cavitation at the impellors.
Due to limited space, a new pump station was constructed over an existing clearwell, suction piping corrections were made, and new variable frequency drives added to provide flexibility in flow delivery. With the improved piping, the new pumps performed beyond expectations and existing pumps improved without changing motors or alignment.

Beardstown Sanitary District – Beardstown, Illinois
The City of Taylorville provides water treatment and distribution to the residents of Taylorville as well as five regional customers. The City’s water supply consists of both surface water (lake) and groundwater (wells) which are blended prior to treatment. Aging facilities and changing regulations on contaminants such as cryptosporidium and nitrate required additional treatment to maintain regulatory compliance to the facility which hasn’t had significant upgrades or improvements since 1983.
The City selected Benton & Associates, Inc. to complete a Facility Plan for the source water and treatment evaluation which looked at renovating the existing facilities or constructing a new facility at a new location. After consideration of capital costs along with Operation and Maintenance Costs, the City council voted to build a new 5.2 MGD lime softening blended water treatment plant at a new location. The new facility features upflow solids contact clarifiers for clarification and softening, gravity sand filtation, and Ultra-Violet (UV) disinfection reactors for inactivation of cryptosporidium and giardia.
The new plant also employed the latest in biological Nitrate removal technology (Biottta – AdEdge Water Technologies) which converts groundwater nitrate into harmless nitrogen gas leaving a safe waste stream discharged to a nearby stream. This is the first biological nitrate removal system in Illinois and the third of its kind in the nation.
