When the City of Bismarck was developing a new pressure zone in the northeast corner of Bismarck, they turned to AE2S to complete a study which evaluated fire flow demand and water quality, among other things through the use of hydraulic modeling. The study compared the costs, benefits, and concerns for eight alternatives that were developed. For a more detailed description click here.

AE2S was retained to develop a Master Plan Update with a planning horizon through 2023, with consideration for longer term issues through 2060. The Update was developed with two prioritized plans of independent capital improvements (to address the uncertainties associated with future regulatory developments) that are intended to provide a balance of annual capital expenditures throughout the planning period. However, in both prioritized plans, initial short-term improvements consist of facility optimization projects that may provide the opportunity for the City to delay, re-prioritize, or eliminate subsequently planned capital improvements.

The project involved the construction of a new 7 million gallon clearwell and a 24 million gallon per day (MGD), expandable to 48 MGD, high service pumping station, and the design and construction of approximately five miles of dual 30-inch ductile iron transmission pipelines in association with the construction of five miles of 14-inch PVC water treatment plant residuals force main; including valves, air release systems, and other associated appurtenances. The project also included an evaporation pond, removal and replacement of four existing high service pumps with three new vertical turbine pumps to transfer water to the new clearwell, and installation of a new triplex booster pump system within the existing water treatment plant for the City of Grand Forks.

AE2S was retained by the Lake Agassiz Water Authority to serve as its representative on the Technical/Study Review Team for the Red River Valley Water Supply Project, which was intended to address water quality and quantity challenges posed by the relatively unreliable and poor water sources available to municipalities and regional water systems of the Red River Valley. In this capacity, AE2S reviewed study documents, provided written comments, assisted water systems with various technical issues, and participated in scheduled meetings and related discussions. Input from AE2S provided direction for the development of alternatives that would meet the long-term water supply needs of the project's stakeholders. For a more detailed description click here.

This project addressed projected water supply shortfalls attributed to anticipated population growth and associated commercial and industrial development for the City. The evaluation included: 1) the preparation of population and water demand projections; 2) water system concept development to supplement the proposed water system capacity from Lewis & Clark Rural Water System; 3) water system concept development to utilize the City's Future Use Permit for the Missouri River; 4) estimation of opinions of total probably project costs and incremental operations and maintenance costs associated with the alternatives; 5) a discussion of implementation considerations such as funding, project phasing, water supply appropriations, land/easement acquisition, government agency review and approval, and environmental compliance; 6) a present worth financial analysis of the considered alternatives and discussion of non-cost considerations; and 7) development of conclusions and recommendations.
