Learn about their challenges and how they battled them.
Challenge: The 25-year-old water treatment facility in the City of Apple Valley, Minnesota, needed updates to meet the needs of a growing population.
Solution: With a water treatment expansion and renovation, SEH helped the City increase the treatment capacity of the facility by 33%, from 18 million gallons per day to 24 million gallons per day.
Key project features
Challenge: With multiple flooding events between 1978 and 2010, the City of Austin, Minnesota, has long experienced the effects of rapid river rise and devastating floods.
Solution: The City implemented numerous floodplain management tools as part of their flood mitigation efforts. These included structural flood mitigation measures for their North Main commercial and business areas.
Challenge: With aging equipment, infrastructure and a new effluent phosphorus limit, the Cambridge Wastewater Treatment Facility in Cambridge, Minnesota, needed an overhaul.
Solution: From facility planning, design, bidding, construction administration and funding services, SEH assisted in the city in making improvements to the facility. The $12-million construction project, which condensed operations from two facilities down to one, touched on all components of the treatment process and added facilities for phosphorus removal.
Key project features
Challenge: An assessment showed the 1.5-million-gallon water tower, an integral part of the water distribution system for the City of Richfield, Minnesota, needed tank reconditioning and telecommunications upgrades.
Solution: The City hired SEH to develop plans and specifications, provide full-time inspection, and coordinate carrier needs for the temporary operation of telecommunication services. This was accomplished all while maintaining continual operation of the City’s onsite fire station, preserving access to nearby Penn Avenue. and accommodating contractor mobilization, a full-containment system and temporary pole for carriers.
Key project features
Challenge: The City of St. Louis Park, Minnesota, needed to improve access, safety and operations for multimodal transportation at a major highway intersection.
Solution: To balance the needs of the regional transportation system while addressing local community and user needs, an SEH team designed a tight diamond interchange with three roundabouts for traffic control.
