Consulting Engineering Services for Comprehensive Sanitary Sewer Evaluation - RFQ
History
The Metropolitan Water Reclamation District of Greater Chicago (MWRD) governs the sanitary sewer collection system for Orland Park through their Watershed Management Ordinance (WMO). The Environmental Protection Agency (EPA) and the Illinois EPA (IEPA) imposed special conditions in the National Pollutant Discharge Elimination System (NPDES) permits issued for the District’s Water Reclamation Plants that requires tributary local and separate sanitary sewer satellite entities to implement measures in addition to those required under the 1985 Sewer Summit Agreement if excessive I/I in the system causes or contributes to sanitary sewer overflows or basement backups. Due to this mandate, the District incorporated an updated Infiltration and Inflow Control Program (IICP) into the Watershed Management Ordinance.
This unfunded mandate, by design, requires technical and project specific assistance to develop and implement a comprehensive, sanitary sewer system evaluation & repair program that incorporates the requirements outlined in the WMO. As these programs are created and implemented, staff will need to return to the Public Works Committee to request approval to perform recommended testing and/or corrective work. A consultant is needed to guide and assist Public Works in developing and implementing a comprehensive sanitary sewer evaluation and repair program that will meet specific short-term and long-term requirements as mandated by MWRD's Watershed Management Ordinance.
MWRD’s WMO requires affected agencies and communities to perform various investigative methods to identify, record, report, monitor, correct and remove inflow and infiltration from the sanitary sewer system. Methods invariably will require the creation and development of programs including manhole inspections, smoke testing, flow monitoring, cleaning and televising of sanitary sewers. Based on the ...
