WASTEWATER
How To Choose Among Wastewater Screen Options
Wastewater screening isn’t one-size-fits-all. The right choice depends on flow, debris, and efficiency needs, with long-term performance and maintenance costs shaping the best solution.
WASTEWATER CASE STUDIES AND WHITEPAPERS

Compact Footprint And Flexible Hydraulics Ease Initial Expansion, Leave Room For Future Growth
When Plainfield, IN, needed to double their permitted capacity from 2 MGD to 4 MGD at their South wastewater treatment plant, they faced a dilemma. Like most treatment plants, space is at a premium, and compact design was needed not only for the current expansion, including the addition of a post aeration structure, but to preserve as much room as possible for projected future expansions.

To the Rescue: The DIMMINUTOR® Makes A Difference At Ross Valley Sanitary District
Ross Valley Sanitary District in San Rafael, California services approximately 47,000 mostly residential customers over a 27 square mile service area. They have 5 major pump stations, which is where Ross Valley found themselves having the most trouble. The existing channel grinders were simply not reliable. “It was a constant headache,” said Philip Marcantonio, Senior Collection System Worker. “The pumps were ragging up sometimes twice a week and sometimes twice a day.” The plant reported that the machines were not efficient at all. “It was a lot of extra work on us to keep the stations going,” Marcantonio said. On top of that, the constant downtime was causing even more than extra work; it was costing the district a lot of money. They knew this was not a sustainable system to keep their plant and stations running.

Horse Racetrack Bets On Flygt For Pump Station Design
200-acre Monmouth Park Racetrack in Oceanport, NJ, is supported by a series of barns and other support facilities that house in excess of 500 horses during track operations. In the mid-1990s the New Jersey Sports and Exposition Authority (NJSEA) constructed facilities to collect horse wash water and first flush stormwater runoff for conveyance to the Two Rivers Water Reclamation Authority (TRWRA), a wastewater treatment facility located in Monmouth Beach.

LATEST INSIGHTS ON WASTEWATER

Einstein once said of compound interest, "He who understands it, earns it. He who doesn't, pays it." The same logic of compounding applies to the organic sediment accumulating on the floor of your drinking water reservoir. The longer you wait to address it, the more exponentially expensive it becomes to fix.
-
Our infrastructure systems have operated in managed deterioration for decades. And not surprisingly, once they deteriorate badly enough and cross over into active failure, all cost discipline disappears.
-
Every day, food scraps disappear into trash bags, are hauled away, and forgotten. But that waste could be turned into something productive.
-
Currently, water infrastructure is outdated and fragile, prone to breakages and leaks. Reactive approaches to water infrastructure are only implemented after an incident and are more expensive than simple maintenance fixes. Geotechnical Internet of Things (IoT) devices enable water and wastewater industry professionals to identify and address issues before they escalate into catastrophic events.
-
Traditional gravity sewers rely on large-diameter mains, deep trenches, and often multiple lift stations — elements that carry significant capital and restoration costs, particularly in rural or rugged terrain. To improve cost efficiency and sustainability, many municipalities are adopting decentralized collection systems such as Septic Tank Effluent Pump (STEP) systems, Septic Tank Effluent Gravity (STEG) systems, and liquid-only sewers.
-
Aeration control strategies often remain conservative and static. Blowers operate continuously, oxygen levels are maintained near maximum, and airflow rates are rarely adjusted in response to real-time biological demand. The result is widespread over-aeration — a condition that does not improve treatment performance but significantly increases operating costs.
