Collection System Rehabilitation
When a collection system is aging, problems can begin to surface because of intrusions or outdated technologies.
HR Green has deep experience in designing rehabilitation of collection systems that takes into account the environment and the needs of the client. We understand how to solve inflow and infiltration issues through rehabilitation design, for a more reliable, efficient and thorough system.
Our services include data collection, rendering of existing structures, recommendations of appropriate rehab techniques, engineering alternatives, integration or develop of GIS systems, asset inventories, design and value engineering of existing systems.
Collection System Rehabilitation Experience
Iowa Great Lakes Sanitary District
The Iowa Great Lakes Sanitary District (IGLSD) intercepts the wastewater from seven Iowa cities (Spirit Lake, Arnolds Park, Okoboji, West Okoboji, Wahpeton and Milford) and the unincorporated areas in the region around the Iowa Great Lakes in Northwest Iowa.
Interceptor Improvements Incorporate “Complete Streets”
Richfield, MN, Edina, MN
The Edina-Richfield Interceptor Improvements project constructed a regional sanitary sewer across Richfield to accommodate redevelopment in Edina. Standard MCES practice is to repair streets in a fashion similar to their original condition. However, HR Green used a Context Sensitive Solutions (CSS) approach to engage the public in the design of 75th and 76th Streets in Richfield. The result is Richfield’s first “Complete Street” system, which encourages walking, bicycling and mass transit use. This method was also less costly for MCES, resulting in a win-win outcome for Richfield and MCES.
Empire WWTP Outfall and Rosemount Interceptor
The Rosemount Empire planning area is located in the southeastern part of the Minneapolis/St. Paul metro area and includes the cities of Apple Valley, Lakeville, Farmington, Rosemount, and Empire Township. Metropolitan Council Environmental Services (MCES) provides wastewater collection and treatment for this area.
