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.

Capitol Region Watershed District (CRWD) and City of St. Paul selected the team of HR Green and Inter-Fluve to conduct a feasibility study, develop concept plans and final design, complete three construction bid packages and construction oversight for the Trout Brook Nature Sanctuary and Regional Trail.
Interceptor Improvements Incorporate “Complete Streets”
Richfield, MN, Edina, MN
The Edina-Richfield Interceptor Improvements project constructed a regional sanitary sewer across Richfield to accommodate redevelopment in Edina. Standard MCES practice is to repair streets in a fashion similar to their original condition. However, HR Green used a Context Sensitive Solutions (CSS) approach to engage the public in the design of 75th and 76th Streets in Richfield. The result is Richfield’s first “Complete Street” system, which encourages walking, bicycling and mass transit use. This method was also less costly for MCES, resulting in a win-win outcome for Richfield and MCES.
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.
Burlington’s Wastewater Treatment Plant Improvements
The City of Burlington had been propositioned by a major industry in the mid-2000s but they were not able to offer the sewer treatment capacity desired of the industry.

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.
The triple bottom line is a framework that considers social, environmental, and economic effects together – it is used to measure the “sustainability” of an action. Wastewater treatment has an impact on all three components of the triple bottom line. Wastewater treatment has led to tremendous improvements to society as a whole by minimizing diseases and improving quality of life; it has also led to far cleaner bodies of water from small streams to oceans. Though human health and the environment have benefitted from the emergence of wastewater treatment as a standard protocol for waste disposal, the benefits have come with a high economic burden to the budgets of municipalities and industries.
