Sewer System Evaluation
and Rehabilitation
Willow Springs, IL
As part of a complete sewer system evaluation and
rehabilitation program to comply with IEPA and MWRD
mandates, HBE coordinated the testing, monitoring,
evaluation and rehabilitation of over 20 miles of sanitary
sewers and appurtenances throughout the Village of Willow
Springs. Our services included the preparation of final
engineering drawings for the entire public system and also
private service(s) rehabilitation, preparation and
assistance in bid letting and the preparation of and
coordination of grant application for reimbursement. Project
costs totaled more than $800,000.
Combined Sewer Improvements
Bedford Park, IL
As Village Engineers, HBE was responsible for the
preliminary review and evaluation of videotapes for 7,200
lineal feet of combined sewer ranging in size from 69-inch
to 90-inch diameter pipe. The existing sewer is constructed
entirely of brick with a 1,000-foot section lined with
gunite. The section of pipe that was gunited was beginning
to show deterioration and was determined to require repairs.
Approximately 350 lineal feet of this portion of sewer
passes under an existing office building. Based upon the
location and depth of existing sewer, the method of repair
chosen was cured in place lining. The estimate of cost for
repairs is $1 million. The Village has not budgeted for
these repairs at this time. The existing brick sewer will
continue to be monitored and evaluated for necessary
preventative maintenance/repair
