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.
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.
Drones have been filling our news feeds with uses such as recreational, military, and drone deliveries, but how can a municipality determine how to leverage this rapidly evolving technology? Many communities across the country are starting to research sUAS uses and invest in sUAS technology and applications.
One Watershed, One Plan: Process, Insights and Tips for Efficient, Effective and Empowering Plan Building
This article presents local soil and water resource organizations with insights into the One Watershed, One Plan (Plan) development process to assist preparation for planning. It synthesizes the experiences of the author during the Pilot phase of the program, his involvement with the development of one of the Pilot Plans and “lessons learned” from BWSR program meetings and documents.
The purpose of water storage tanks is usually to meet peak demands, such as fire flows and times of the day when water use is high. There are a few items to consider when selecting a new water storage tank for your community or industry. Traditionally, it has been a common practice of many water
Keeping up with changes in state laws can be a full time job for municipal employees. The experts in HR Green, Inc.’s Governmental Services Business Line review and keep up with the changes in Building Codes and Code Enforcement. Unlike standard Building Codes, the Illinois Plumbing Code, the Illinois Energy Conservation Code and the Illinois Accessibility Code are all state mandated codes. HR Green urges leaders to take note of some very important changes.
Many industries have some level of wastewater pretreatment before discharging to the local Publicly Owned Treatment Works (POTW). In the food and beverage industry, pretreatment with Dissolved Air Flotation (DAF) is common to remove fats, oils and greases, along with associated Biochemical Oxygen Demand (BOD) and Total Suspended Solids (TSS). These food and beverage companies are in the business of making their products, not wastewater treatment. So, often times, selecting the right piece of equipment can be a challenge.
In many communities, the urban environment and human intervention have impacted our natural streams and rivers. Impervious surfaces such as roads, parking lots and buildings take away areas where rainfall would normally be slowed down, spread out and soaked into the ground. Further exacerbating the problem, streams in urban areas are often straightened or channelized to make more room for development.
Modern wastewater treatment plants are technologically advanced facilities that require a great deal of knowledge and skill to operate. While many people only consider the treated effluent discharged from these facilities, treatment plants must actually process, discharge, and dispose of two separate wastewater components.
Communities across the country have aging and inadequate water infrastructure. Most of our underground water infrastructure was built 50 or more years ago, in the post-World War II era. In some older urban areas, many water mains can even be a century or more old. It is estimated $2.6 billion is lost as water mains leak treated drinking water. In addition, billions of gallons of raw sewage are discharged into local surface waters from wastewater conveyance systems.
