Wastewater Conveyance and CSO Abatement
Sanitary Sewer Analysis
Many communities throughout the Midwest have inefficient combined sewers. Over time, sewers have deteriorated and are not functioning as designed. The result is combined sewer overflows (CSO’s) occurring at an unacceptable frequency. These CSO structures and contributing sewer networks can be analyzed using state of the art computer simulation models such as SWMM that accurately depict the flows in a complicated sewer system.

Engineers at CBBEL have experience in analyzing combined sewers and separate sewer systems and have found innovative solutions to reducing CSO’s and sanitary sewer overflows. CBBEL staff have used a cost-effective mixture of flow monitoring, smoke testing, night flow isolation, and dye testing to prepare recommendations for municipalities.

CBBEL sewer rehabilitation work includes:
 

Sewer lining
Micro-tunneling
Directional boring
Traditional jacking and boring
Pipe bursting
Manhole rehabilitation
Open cut sewer replacement

Lift Station Analysis and Design
Due to Indiana’s topography, sanitary sewer and storm conveyance systems often require lift stations to convey flow. These stations are aging, and many are not functioning as designed. Others are overloaded due to increased flows from urbanization. CBBEL has a complete staff of civil and mechanical/electrical engineers that are capable of design, rehabilitation, and upgrading of all types and sizes of lift stations.

CBBEL’s experience includes consulting with operation and maintenance (O&M) personnel and advising O&M crews on problems with facility operations as well as making recommendations for improvements
