The City of Williston has experienced significant growth in the past couple years due to the recent increase in oil exploration. This has caused an influx of people and industries to move to Williston to support the oil industry. As a result, many areas outside of the Williston City limits have requested access to City sewer service
The City of Havre, MT operates a 1.8 MGD activated sludge wastewater treatment facility. The City of Havre received a MPDES permit necessitating an upgrade to its treatment facility to meet more stringent ammonia and disinfection requirements. Stringent nitrate plus nitrite, total nitrogen, and total phosphorus limits are expected in the next permit cycle
Faced with aging infrastructure, the potential expansion of a significant industrial user, and the desire to consolidate treatment facilities from two different sites to a single existing site, the Grand Rapids Public Utilities Commission (GRPUC) retained AE2S to plan, design, and administer construction of a WWTF upgrade and expansion project
Like many communities in Western North Dakota, Watford City is experiencing rapid growth. As a result of a phased Wastewater Collection and Treatment Facility Plan and Capital Improvements Plan completed by AE2S in 2010 to address the challenges, the City embarked upon phased improvements to its wastewater treatment facilities
AE2S, teamed with another consultant, was selected by the Big Sky Water and Sewer District (District) for preliminary and final design engineering and construction administration to upgrade and expand the WWTF to support diversification and expansion of its exiting effluent reuse and disposal options
AE2S worked with the City of Otsego to complete a Wastewater Master Plan in 2018 that charted the wastewater utility’s direction for the next 80 years. The first major project from the Master Plan is a Biosolids Building, which will dewater thickened waste activated sludge (TWAS) from both the City’s East WWTF and West WWTF
AE2S designed the rehabilitation and process modifications for four 100-foot final clarifiers at the Sioux Falls Water Reclamation Facility. The existing WRF includes trickling filters followed by activated sludge, but the improvements phasing included nutrient removal within the planning period that decommissioned the trickling filters and upgraded the activated sludge to full biological nutrient removal (BNR)
The existing City of Sturgis wastewater treatment facility consists of an influent Parshall flume, mechanical 6mm fine screen, an effluent flow meter, an aeration pond, two secondary treatment ponds and one irrigation storage pond. Emergency discharges directly to nearby Bear Butte Creek have become a common occurrence in recent years because irrigation properties have not been able to handle the volume of treated wastewater produced by the facility
The City of Williston’s rapid population growth necessitated a new water resource recovery facility (WRRF). The City retained AE2S to develop a Preliminary Engineering Report (PER) for the new WRRF, along with preliminary design documents of the selected alternative.
AE2S identified future treatment requirements based on capacity needs and treatment discharge levels. Capacity needs were based on population growth patterns
