Collection System Improvements
In the spring of 2015, portions of the City of Liberty flooded, revealing extensive problems with infiltration and inflow in the City’s collection system. The City had struggled to address needs and develop plans for the maintenance of their sanitary sewer collection system, and they sought a cost-effective way to identify problem locations and help in planning future operations and maintenance work.
Elevated Water Storage Tank
The City of Keokuk is located in southeast Iowa along the Mississippi River. Keokuk Municipal Water Works currently operates a water treatment plant with an average daily demand of 12 to 14 MGD. The source of the water is the Mississippi River. A large percentage of water consumption comes from industrial users. In particular, the

HR Green provided bidding and construction phase services to the City of Cleveland, Texas for their East and West Wastewater Treatment Plant modifications project.
Detention Basin Retrofits
St. Peters, MO
In 2012, the City of St. Peters began a comprehensive citywide stormwater management program (SMP) aimed at preserving natural habitat, flood mitigation, creek bank stabilization and detention basin rehabilitation/retrofit, all with the goal of reducing property losses and pollution, and increasing water quality.
Gillette Street Outfall
Midtown and Montrose, one of the earliest sections of Houston to be developed, currently lacks a storm sewer system that is sufficient enough for the densely populated area.
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
International Plaza Drive Reconstruction
St. Ann, MO
International Plaza Drive is a collector roadway in the northern section of the City of St. Ann that serves as a major entry point into the City. Innovative water quality measures were used to address the water quality requirements of the project.
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.
The Woodlands Neighborhood Green Initiative Infrastructure
The Village of Hinsdale, Illinois commissioned two separate engineering studies to determine options for improvements to the storm water management and aging/deteriorating infrastructure of the Woodlands Neighborhood.
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.
County Highway 19 Stormwater Re-Use Project
Washington County, MN
A two-mile long county road expansion was designed to provide nutrient and suspended solid load reductions to downstream water bodies.
Wastewater Treatment Facility Improvements
The Facility Plan report included a thorough evaluation of existing treatment processes and structures as well as recommended improvements to meet future conditions.
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.
Water Reclamation Facility Effluent Filter Improvements
Sioux Falls, SD
The City of Sioux Falls Water Reclamation Facility (WRF) treats wastewater from throughout the city, thus protecting the Big Sioux River from pollution. This outstanding project replaced filters at the WRF, re-using the existing concrete tanks where the filters were located.
Increased levels of manganese in drinking water supplies have raised concern in some communities and increased speculation that the U.S. Environmental Protection Agency (EPA) will make regulation changes. Manganese is a naturally occurring element found in groundwater, very acidic soil, and foods such as seeds, grains, nuts, legumes, green leafy vegetables, and in drinking water.
Obtaining grant funds for various projects is paramount for most communities; however, securing and managing these funds for critical projects is no simple task. In an ideal world, effective Capital Improvement Planning allocates funding for improvements; however, when accidents occur or Mother Nature strikes, disaster recovery efforts can be a significant funding challenge for communities. Grant funding knowledge is essential to ensure that a community can recover from disaster and prevent future loss of life and property.
Lead water mains have become a significant concern nationwide as stories have made headlines warning of high concentrations of lead in drinking water. Understanding the complexities for replacing lead services lines (LSL) in a community can seem daunting. Often community leaders and stakeholders don’t understand their options for implementing an LSL replacement plan.
Partially grouted masonry shear walls are common in North America. Construction of partially grouted concrete masonry shear walls can benefit greatly by placement of joint reinforcement in bed joints of each or every other course instead of deformed reinforcement in bond beams, because placement and grouting of bond beams slow construction. Joint reinforcement is already used to help control cracking and provide prescriptive horizontal reinforcement. With sufficient area and ductility of wire, joint reinforcement can also provide the tension capacity to span across cracks in shear walls and to act as primary shear reinforcement for in-plane shear forces.
The zebra mussel, an aquatic invasive species (AIS), has made its way above Gavins Point Dam near Yankton and has rapidly increased its presence in Lewis and Clark Lake. One female zebra mussel can produce a million eggs in one year, with the mussels attaching to infrastructure and watercraft while creating problems for fish and other life sharing the waters.
Surveyors from HR Green spent time in November looking for 200 manholes in Blanco Texas. The project to survey and inventory the city’s wastewater system is a wastewater asset management project awarded to the city by the Texas Water Development Board.
A well-informed constituent will feel engaged and involved. Communities striving to improve communications with their residents and visitors should periodically evaluate the technologies available and weigh their strengths against the community’s need. Some technologies are excellent at getting information distributed to a broad audience quickly, while others allow for interaction and multimedia applications.
This quarter, HR Green is focusing on the concept of resilience and how municipalities recover from or adjust easily to misfortune or change. Communities are much better positioned to deal with disasters, retain a healthy position and regain normalcy when properly prepared. There are few natural disasters more devastating than flooding. Water, a vital life-force,
Most Americans take the water systems that bring clean water to and from their homes and businesses for granted. They turn on the tap and flush the toilet without thinking twice about where that water came from or where it will go. But could you imagine a day without water? Without safe, reliable water and wastewater service?
The Sioux Falls Water Reclamation Facility (WRF) treats primary and secondary sludges in three primary anaerobic digesters and one secondary digester. Treated sludge is stored in lagoons until disposal by land application. Continuation of the land application process will require significant investment. The primary purpose of this study is to evaluate alternative biosolids handling and disposal methods. The study includes a forecast of biosolids production rates due to growth and future nutrient removal treatment processes. The study also addresses processing and storage options, and establishes a 20-year biosolids management plan.
