Mandan Ground Storage Reservoir

Mandan Ground Storage Reservoir

The City of Mandan was faced with a failing 75 year old, one million gallon steel ground storage reservoir originally built on the Collins Avenue storage site. The reservoir was originally built near main street and established residential and commercial areas. In 2007, the reservoir experienced several leaks and the City was mandated by the North Dakota Department of Health to repair the tank

St. Cloud Master Planning and WTP System Improvement

St. Cloud Master Planning and WTP System Improvements

Although the St. Cloud Water Treatment Facility (SCWTF) was relatively “new”, numerous existing systems had been identified as problematic from either an operational, maintenance, or performance standpoint. The condition of process equipment was on the decline, regulatory requirements were increasingly strict with critical deadlines rapidly approaching, and consistent community growth was challenging the treatment capacity of the facility

Watertown Municipal Utilities Water Treatment Plant

Watertown Municipal Utilities Water Treatment Plant

Watertown Municipal Utilities (WMU) administers the water utility within the City of Watertown, SD. Due to compliance issues with increasingly complex surface water regulations and concerns over elevated concentrations of disinfectant by-products (DBPs), along with the age of many components within the Lake Kampeska WTP, the continued use of the surface water became less attractive to Watertown

Bismarck Horizontal Collector Well

Bismarck Horizontal Collector Well

To address increasing water demands, and to provide a reliable water source for the community, the City of Bismarck retained AE2S to design a new Horizontal Collector Well (HCW) intake for the Bismarck Water Treatment Plant. AE2S followed a phased approach for design of the HCW system. The project was separated into three components; Phase I consists of the collector caisson and lateral wells, Phase II is the raw water transmission line from the well to the WTP, and Phase III includes the pumping station at the well

Fairmont Water System Planning and New WTP

Fairmont Water System Planning and New WTP

The Fairmont Water Treatment Plant (WTP) was experiencing treatment capacity limitations as well as challenges related to aging infrastructure, including operational difficulties related to deteriorating and outdated treatment processes. Proposed drinking water regulations would likely require improvements or advanced treatment processes to be implemented in the future at the WTP

Williston Water Treatment Plant Expansion

Williston Water Treatment Plant Expansion

The expanding oil and gas industry in northwest North Dakota strained water systems’ abilities to keep up with domestic and industrial water needs. As the economic hub of the region, the City of Williston continues to experience considerable growth, and it’s anticipated that the growth will continue. Exacerbating the domestic water demands are industrial water demands from the oil and gas industry within the region, estimated at over 40 million gallons per day (MGD)

Fargo Membrane Water Treatment Plant

Fargo Membrane Water Treatment Plant

The Fargo Water Treatment Plant (WTP) uses a combination of water from both the Red River and Sheyenne River, with the Sheyenne River being used nearly 40 percent of the time. Unfortunately, changing water quality in the Sheyenne River was challenging the City’s ability to utilize this important water source because it contains high salt concentrations, including sulfates and bromide, which posed a significant treatment challenge to the existing Fargo WTP

Robbinsdale Water System Improvements

Robbinsdale Water System Improvements

The City of Robbinsdale is an inner ring suburb of the Minneapolis Metropolitan area with about 14,000 residents and provides an average of 2 MGD of potable water to the community. The City became fully developed in the 1970s and was experiencing redevelopment and pressure to add additional density in various locations throughout the City

Pierre Water Treatment Plant and Intake Improvements

Pierre Water Treatment Plant and Intake Improvements

Currently, Pierre’s drinking water is obtained from a series of groundwater wells located throughout the city. Water is treated at each wellhead and pumped to storage tanks throughout the community.
In 2017, the City of Pierre began looking into treated water options following a community survey

Woodbury PFAS Water Treatment & Management

Woodbury PFAS Water Treatment & Management

In 2004, PFAS were first found to have contaminated drinking water supplies in parts of the eastern Twin Cities. Over the last 15 years or so, PFAS have been discovered in Woodbury’s groundwater supply, and research has been conducted to identify the source and level of contamination. Most of the contamination has been traced to four dumps or landfills in Oakdale and Woodbury, at the 3M manufacturing facility in Cottage Grove, and at the Washington County landfill
