A deep-tunnel pumping system for Columbus, Ohio’s OARS project uses adjustable-speed Flygt pumps to manage extreme head variations and efficiently dewater a 215-foot-deep, high-capacity sewer tunnel after major flow events.

The most effective strategy to safely manage a force main inventory is to implement a risk based approach for any data collection, inspection, condition assessment, and management techniques. Using asset risk to guide the management strategies, an owner/operator can ensure they are implementing the right approach, at the right time, with the lowest financial impact.

Around the world, critical valves are in poor repair, or even inoperable. When critical valves fail, managers have effectively lost control of their system, increasing vulnerability to water main breaks or any other system hazard. Once valves have failed, utilities have traditionally sought to replace them, often at great cost, both in terms of time and expense.

Ahmed Ramadhan Juma (ARJ) is supplying 6 water transfer sets (11KW-200KW) and 7 water booster sets (4KW-37KW) utilising vertical and horizontal multistage pumps. The water booster sets are fitted with “Hydrovar”, a bespoke variable speed drive (VSD) designed for pumping applications.

HomeBiogas identified the possibility to support the development and transformation of such communities through the use of their patented Bio-Toilet, a compact and portable waste management solution that converts waste into renewable biogas for cooking – all without the need for electricity.

Allegheny County Sanitary Authority (ALCOSAN) is a municipal authority that provides wastewater treatment services to 83 communities, including the city of Pittsburgh, reaching a total population of 1.2 million people.

Due to a projected population increase, discharges from the site were required to undergo advanced biological treatment to reduce levels of phosphorous returned to the River Aire. This requirement was part of the UK Environment Agency’s Water Industry National Environment Programme (WINEP).

A condition assessment helps to understand the state of the prestressing wire which provides the pipe’s strength. PCCP manufactured during the 1970s is prone to low ductility in the wire and susceptibility to hydrogen embrittlement, both of which increase the risk of failure. Worn PCCP can rupture with no warning, potentially shutting down the entire facility.
