The Bagmati is both a sacred river and a city sewer, running through Nepal’s capital city of Kathmandu before heading into the mountains and over the Indian border.

The ARC-Boat was developed by HR Wallingford and employs SonTek-proprietary Acoustic Doppler Profiler (ADP®) technology. The HydroSurveyor is a highly sophisticated system which includes 5-beam depth sounding, water velocity profiling and navigation capabilities. When mounted in the ARC boat, the HydroSurveyor scans the reservoir as it is guided across the water’s surface. Recorded data is then analyzed by HydroSurveyor software to produce accurate depth measurement in addition to bathymetry maps of the entire water body. With a small amount of post-processing in GIS or 3-D CAD, an accurate water volume can be determined.

The Caribbean Community Climate Change Centre (CCCCC) awarded YSI Integrated Systems and Services (a division of Xylem Inc.) a contract

It’s hard to picture just how flat Australia’s Murray-Darling Basin is, but picture this – tens of thousands of square kilometers braided with slow-flowing rivers and streams with virtually no fall in their channels.

These are not easy times to run an irrigation district in California

Flow monitoring site and hydraulic conditions that can impact a stable stage-discharge relationship comprises of unstable section control, sediment transport, debris, vegetation, off-channel storage, variable backwater effects and unsteady flow conditions.

Whether it is a borehole application requiring outdoor enclosure or surface mount pump and motor requiring a drive to withstand corrosive environment, the IPC has the right solution. Each drive enclosure is constructed to provide a different degree of protection to personnel against access to hazardous parts.

Pumps are everywhere in agriculture, essential both for irrigation and for heating, ventilation and cooling (HVAC). But water needs change, and irrigation systems don’t always require a constant flow rate or constant pressure. Variable frequency drives (VFDs) are electric controllers that vary the speed of the pump, allowing the pump to respond smoothly and efficiently to fluctuations in demand.

Shanghai Xinlun Paper was upgrading its pulping and paper-making process. As this was taking place, new regulations came into effect that required the mill to invest in secondary wastewater treatment so it could meet stringent effluent limits of 100 mg/l chemical oxygen demand (COD), 30 mg/l biochemical oxygen demand (BOD), and 200 mg/l total suspended solids (TSS).

BALTEN needed to modernize its outdated infrastructure and software platforms, so it could optimize its irrigation water transportation system and improve the overall performance of its irrigation water service.

Bell & Gossett manufacturer’s representative, Hydro-Flo, in Brookfield, Wisconsin, presented a solution to the VA’s pump room challenge: the VSX vertical split case pump.

By implementing a proactive management program, utilities can virtually eliminate the risk of failure within their PCCP inventory. Even utilities that have not experienced a large-diameter PCCP failure, can realize significant capital program savings by managing these assets in place of replacement.

While evaluating wire breaks are an important part of PCCP management, it is important to acknowledge additional factors beyond wire breaks. By acknowledging additional condition factors, limitations of wire break assessment, and considering other rehabilitation approaches, there may be a more sustainable PCCP management approach.

Monitoring water systems can be difficult in a community like Big Sky with a large seasonal population, extreme weather and elevation changes. Leaks and other issues may occur in residences when no one is there to notice. The District also bills quarterly, which makes finding problems early on even more critical for customers.
