Pump Station & Storage Reservoirs
The new Edgerton Pump Station (EPS) was constructed to facilitate bringing purchased water from Lewis & Clark Regional Water System (L&C) to the LPRW system.
Southwest Minnesota
Sanitary Sewer Rehabilitation
The project was bid and came in under budget. Manhole lids were raised to provide better access in some areas, and rehabilitation of the sewer system was completed to give another 50 years of life to the City’s much-needed infrastructure.

Treatment Plant & Well Exploration
DGR Engineering worked closely with OCRWS to design a new Water Treatment Plant to target iron and manganese removal from a shallow groundwater source near the site.
Northwest IA
Wastewater Treatment Facility
MBBR technology was chosen based on cost, operational flexibility and most importantly, limited land availability.
Sanborn, IA
Wastewater Treatment Facility
City of Orange City, IA prepared for the future by adding a mechanical treatment facility to meet both capacity and compliance.
Orange City, IA
Wastewater Treatment Facility
Designed a SAGR system to be utilized as a polishing step following the City’s aerated lagoon system. The system includes a synthetic liner, aeration lines, rock media, an insulating mulch layer, control structures, and related piping.
Hull, IA
Low Pressure Collection System
Analyzed collection and treatment alternatives. Designed a septic tank effluent pump (STEP) system for Superior’s residents.

Lift Station, Control Panel, Valve Vault
The SE Sanitary Sewer Extension project provided sanitary sewer service to a previously un-serviced area southeast of Dell Rapids, SD.
Dell Rapids, SD
Wastewater Treatment Facility (SBR)
The new SBR system utilizes the existing aeration lagoon for equalization and another lagoon cell for sludge storage, which reduced the cost of the project for the City and provided more operational flexibility.
Dell Rapids, SD
Digester Improvements Project
Analyzed digester cover and mixing system alternatives due to condition of existing plant equipment. Selected cover and mixing system to best fit the City’s request for potential future digester gas re-use to reduce plant operational expenses.
Estherville, IA
Wastewater Treatment Facility
The new plant, rated for 5.3 million gallons per day (MGD) peak day, doubles the capacity of its predecessor.
