Holder Construction, Inc. of Atlanta was contracted to expand Gwinnett County's Cultural and Civic Center in Georgia. According to EPA's regulations and state laws, projects such as this require a NPDES Construction Activity permit.To address the monitoring side of this compliance issue, Holder Construction regularly uses traditional stormwater monitoring systems. However, in this instance, they decided to implement both a traditional system and a newer system, created through a partnership of WRT and NIVIS LLC. Holder Construction did so in order to compare results and operational efficiencies between both types of units.

Donala Water and Sanitation serves a large community of upscale homes in suburban Colorado Springs. In 1995, Donala turned to GMS Engineering of Colorado Springs to create a Request for Proposal for a comprehensive radio-based telemetry network that would grow with the rapidly expanding district. From the RFP, a Motorola MOSCAD wireless telemetry system was selected. Once it was installed, the district began to realize benefits from the new technology.

One of the major problem areas in St Petersburg, Florida has two hospitals and a nursing home that discharge to a common sewer line. Historically, the city had to clean this section of the sewer line at least four times a year to avoid blockages and sanitary sewer overflows. Working together, the city and one of the hospitals took action to control the discharge of grease from the hospital's facilities and to reduce the costs of maintenance for both the city and the hospital.
If you go looking for a particular sewage treatment plant in Cincinnati, Ohio, the first thing you'll notice is--you might not notice it at all. In fact, you might drive right by the facility, dismissing it as just another office building. It just does not look like a treatment plant.
Stormwater Retrofitting to Protect Drinking Water Reservoirs from the Impacts of Urban Runoff - Part 2
The Kensico Reservoir Stormwater Management Program is designed to reduce fecal coliform bacteria and turbidity delivered to the reservoir by controlling and treating stormwater. The first phases of the project, assessment of the watershed, site selection and the screening and design of stormwater control and treatment facilities, were completed in July 1998. Facility construction began in the spring of 1999 and completed early in 2001. DEP has committed to monitoring and evaluating facility performance and maintaining the facilities.
Stormwater Retrofitting to Protect Drinking Water Reservoirs from the Impacts of Urban Runoff - Part 1
This paper summarizes the stormwater management element of the program and its control of the two key pollutants regulated by the SWTR: fecal coliform bacteria and turbidity that are conveyed to the reservoir by stormwater.
To meet federal Surface Water Treatment Rule requirements & U.S. Environmental Protection Filtration Avoidance mandates, the NYC Environmental Protection Dept developed a proactive program
Recent implementation of the Long Term 1 Enhanced Surface Water Treatment Rule (LT1ESWTR) has increased potable water sampling and analysis requirements for an additional 11,000 treatment plants serving more than 18 million Americans.
Using reclaimed water for non-potable purposes as a means of conserving potable water supplies is the most prevalent method of water reuse in the United States today. One of the significant challenges for water reclamation facilities is to keep up with the demands for safe, compliant chlorine (Cl2) treatment. One utility that is effectively meeting this challenge is Southern California’s Otay Water District.
Built in the early 1970s, The Oakland, Maine, Wastewater Treatment Facility (WWTF) treats and discharges approximately 300,000 gallons per day (gpd) of wastewater to the Messalonskee Stream. The facility was designed as a conventional activated sludge secondary treatment system to be used principally for BOD and TSS removals. The secondary effluent enters the Messalonskee Stream upstream of several impoundments. This practice has resulted in a steady decline in the water quality of the stream as evidenced by increased algae blooms and other signs of euthophication in impoundments located downstream of the discharge.
