Collections Wet Weather Management

Faced with the threat of permit violations or even fines, municipalities are under the gun to control wet weather events in a manner that minimizes storm water discharges into local water ways. Older cities with combined sewer systems are particularly vulnerable. Many different mitigation strategies, ranging from holding ponds to deep-rock tunnel projects, are being implemented as a means to store high flows during wet weather events.

Distribution Water Pumping

Reliable access to drinking water is an overlooked necessity to the modern world. Water is transported for supply and distribution by gravity-fed or pumped infrastructures. When using pump stations, it is critical to ensure full capacity is always readily available. Standard design practices were created to promote reliable operation, but the technology available has not always been up to the task.

Filtration Filter Effluent Control

Most drinking water plants combine a conventional gravity-fed filtration system with a means for disinfection as part of the water treatment process. As the last stage of particle removal prior to disinfection, filtration plays a critical role in assuring safe water quality, given that many pathogens can escape common methods of disinfection under the cover of particle-filled water. Filter performance is evaluated based on turbidity, which effectively uses the clarity of liquid to indicate the amount of particulate present in the water.

UV Disinfection Effluent Level Control

Ultraviolet (UV) disinfection is a chemical-free process often employed by wastewater treatment operations as the last stage of treatment to meet tight bacterial limitations on plant discharges. The reliability and efficiency of a UV system is critical to mitigating the threat of permit violations and fines for the discharge of improperly disinfected wastewater effluent. For UV systems with horizontal or slanted lamp orientation, the means to control water levels in the channels is a known trouble spot often stemming from the method of actuation used to regulate said levels.
