Managed by the private, non-profit South Jasper Water Supply, Buna, Texas’ water system contains 91 miles of un-looped distribution pipe with historical water losses of up to 30%. A small operations team is responsible for monitoring two water plants, reading 700 meters, repairing leaks, and flushing water to control the water quality. In an effort to spend less time manually flushing hydrants and focus more time on repairing leaks to reduce non-revenue water loss, South Jasper Water Supply purchased and installed two (2) Hydro-Guard® HG-1 Basic/S Flushing Systems.
Although the city of Bozeman, Montana’s stormwater system has been silently producing front-page news for decades, it has typically only flowed into the spotlight because of an incident or an emergency.
The city of El Paso, TX, lies on the tip of the Chihuahuan desert, and it is not uncommon for a year’s worth of rain to occur in a matter of days during the summer.
The user population of a Central Texas resort system does not reach its peak until summer and the resultant levels of peak and low usage vary widely. This fluctuation impacts levels of disinfectant residual and, consequently, water quality — especially at the end of the line. Manual flushing of the utility's hydrants to maintain water quality has resulted in excessive time and labor as workers must access the outlying areas.
The AquaStorm™ cloth media filtration system is designed as an economical and efficient solution for the treatment of wet weather applications. This system utilizes a disk configuration and the exclusive OptiFiber PF-14® pile cloth filtration media to effectively filter high solids waste streams with and without the use of chemicals as determined necessary for application-specific water quality. This system is ideal for wet weather applications due to its proven removal efficiencies and high quality effluent, even under varying influent conditions.
Wastewater Collection System
Orenco Sewer™ (effluent-only sewer) is a cost-effective, environmentally sound wastewater collection system. With an Orenco Sewer, raw sewage flows from a house or business to a watertight underground tank. Only the filtered liquid portion is discharged (by either pump or gravity) to shallow, small-diameter collection lines that follow the contour of the land. Solids remain in the underground tank for passive, natural treatment and only need to be pumped every 10 to 12 years (depending on the number of residents and the tank volume).
Orenco Sewers take significantly less time to install than conventional sewers. And in an Orenco Sewer, material and excavation costs are reduced because the inexpensive collection lines are shallowly buried just below the frost line. Because only liquid is being pumped, system designers don’t need to worry about minimum velocities and associated grades. This simpler installation process causes less disruption to communities and allows businesses to operate normally during construction.
StormTEE® litter control screens are ideally suited for the simple, affordable removal of trash/litter/debris and associated pollutants from stormwater flows in a variety of applications. These patented, self-cleaning deflector screens can be used alone or in conjunction with other devices, including the combination fine- particle separation and oil/water coalescing modular unit as part of a complete BioSTORM® stormwater treatment system. StormTEE® deflector screens are easy to install in both new construction projects and is perfect for retrofits too.
As a Sustainable Drainage System (SuDS), the d-Rain Joint™ is a simple, low-cost, and robust onsite storm water management alternative compared to other permeable, pervious surface options and can be used wherever a permeable, pervious driveway, parking lot, street or walkway is needed.

The 5000s model of pH control systems from Fortrans features a full size utility building with lockable steel door, lights and shelving. The 5000s offers similar process water and stormwater treatment capabilities as the 5000b system.
As storm activity continues to grow, utilities are under increasing pressure to mitigate sewer overflows. Building enough storage to handle the excess runoff until it can be treated is no longer practical — in most places, it’s not even feasible to create a large enough space — and the issue will only get worse as storms continue to intensify. Meanwhile, most settling technologies that address overflows require chemicals and a complex process to start up, shut down, and store through off-peak times.
Partnering with the Water Research Foundation, Brown and Caldwell has developed the Blueprint for One Water — a user-friendly document for the practical application of 'One Water' planning. According to Lisa Skutecki, Brown and Caldwell's Southern California Water Resources Group Manager, 'One Water' is the concept of breaking down barriers across the water sector.
