Construction Phase Services Experience
Menlo Elevated Water Tower Refurbishing
Sioux Falls, SD
HR Green provided design and construction observation services for the recoating of the 1.5 million gallon spheroid water tower at Menlo Park.
Aquifer Testing and Well Field Development
Fort Madison, Iowa
The City of Fort Madison desired improvements and expansion of its existing water supply and treatment facilities. Groundwater from the Mississippi River alluvial aquifer was the preferred option to supply 6.0 MGD, which could increase ultimately to 9.0 MGD. HR Green conducted preliminary research of the geology and hydrogeology of a 23 square mile area
Elevated Water Storage Tank
By spreading the towers further apart and reducing line velocities, less pressure loss should be seen on the outlying areas of the distribution network in the City of Keokuk.
3 Million Gallon Reservoir Replacement
The Watertown Municipal Utilities (WMU) utilizes a 3 million gallon water storage reservoir, located at the Water Treatment Plant, for both water storage and as a contact basin to achieve proper contact time (CT) for disinfection.
Water System Evaluation
The City of Palo is a town of approximately 900 people which had no city-wide public drinking water distribution system prior to the flood of June 2008.
Addresses Aging Infrastructure with Facility Plan
The City was in the midst of rapid growth and it quickly became apparent that the community needed master planning completed for its water and wastewater system to address aging infrastructure in the older portions of the community as well as expansion plans for new developments.
Water Purification Plant Filter Expansion
Sioux Falls, SD
The City of Sioux Falls Water Purification Plant (WPP) provides potable water for the greater Sioux Falls metro area. Master planning by previous consultants revealed a need for increased capacity to meet future water demands. Several “bottlenecks” were identified within the WPP treatment processes, and one of the most critical was the filtration process.
Reverse Osmosis Water Treatment Facility
Ft. Madison, IA
The City of Fort Madison placed into operation a new 5 mgd reverse osmosis water treatment facility in the summer of 2010.
Hartley Reverse Osmosis Water Treatment Facility
The northwestern Iowa community of Hartley has historically derived municipal water from the Dakota Sandstone aquifer, which can produce mineral-rich water with an increased possibility of contamination from farm chemical leaching. Historically treated by aeration and filtration for iron removal, this groundwater source remained with extremely high hardness, sulfate, and total dissolved solids levels earning its reputation for some of the poorest drinking water quality in the State of Iowa.
