For decades, the City of Richmond’s Department of Public Utilities has been working to reduce combined sewer overflows (CSOs) and improve water quality in the James River. Despite making significant improvements, the City still experiences between one and three billion gallons of annual overflow and is actively working to reach Department of Environmental Quality (DEQ) water quality goals.

An increasing number of certification bodies, including NWRI and the USEPA’s UVDGM, require the use of original components in UV water disinfection systems to achieve compliance. But certifications and local compliance policies are different in different parts of the world, including the Middle East region.

Even in coal-dominated Kentucky, renewable energy is getting more attention as federal and state tax incentives add up, and the federal government moves closer to capping carbon dioxide emissions and making coal power more expensive.

The Water Authority was one of the first agencies to take a proactive PCCP management approach. They began an aggressive condition assessment program in 1992. This early program relied primarily on internal visual and sounding inspections.

Water Well Trust, a nonprofit partner of Xylem and Hometown H2O, is a domestic water program working to bring access to clean and sustainable water to the more than 2 million Americans without it.

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.

According to Utilitalia, 38 percent of water is lost on average from the country’s distribution networks. By reducing these losses, the country’s utilities can achieve a more sustainable water supply, lower energy demand, and better financial stewardship.

O.Y Water’s employees are consistently participating in Xylem’s professional trainings and for three decacdes, they are the people who are recognized with the FLYGT brand in Israel.

In response to the COVID-19 pandemic, Global Ecology Group (GEG) developed a fogging system to support the delivery of ECAS solutions in benign disinfection applications. GEG’s Founder and CEO, Owen J. Morgan, has been developing ECAS since the early 1990’s but enlisted Xylem’s help to create amore accessible, portable ECAS fogging system for everyday spaces such as offices and vehicles.

The city of Columbia, Tennessee, experienced a major pump failure in the spring of 2020 that led to sewage overflows, spurring them to engage Xylem Rental Solutions for an emergency pump rental. Xylem engineered a custom temporary bypass system with Flygt electric submersible pump.

Retrofitting or upgrading the fire protection system of an existing facility is not uncommon, necessitating a temporary fire protection solution that integrates with the existing pumping system to ensure continuity and compliance.

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.

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.

Discover how the Lake Huron Primary Water Supply System leveraged Xylem’s advanced monitoring and inspection technologies and engineering analyses to identify urgent repair needs and plan future maintenance and capital projects. Learn how this approach helped the utility improve reliability, save money, and extend the life of critical infrastructure.

Air Selangor is a large water distribution company owned by the Malaysian state of Selangor. The public utility serves a population of 8.4 million residents and manages over 6200 kilometers of trunk mains, ranging from 300mm up to 2200mm, with much of the pipelines located in remote areas of the state.

Safety upgrades imposed by the United States Nuclear Regulatory Commission (NRC) several years ago required nuclear power plants across the United States to review operations and enhance safety protocols. As a part of this process, a nuclear power plant located in the northeast of the U.S. sought an emergency back-up solution to inject cooling water into the plant reactor in the event that all other means of cooling failed.

Alliance Resource Partners, L.P. faced a two-pronged water challenge at one of its many underground mines. At the South Mine of the company’s Gibson County Coal in Indiana, solid-laden water needed to be pumped out of the mine, and a dewatering system needed to be installed in an area with limited space. Multiple pumps had to fit into a mine void less than eight feet high with a narrow, 20-foot entry span.

Delta Sand & Gravel Co., located in Eugene, Oregon, has been providing quality aggregate materials, service and expertise for almost nine decades. The company offers a full line of aggregate products for year-round, all-weather construction and demolition landfill. Xylem has partnered with Delta Sand & Gravel since 2013, to provide holistic water management solutions.

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.

In the U.S., mines operate under strict Environmental Protection Agency (EPA) regulations; as such, pipelines must be carefully monitored and maintained.

One of the largest U.S. producers of construction aggregates decided to relocate their processing plant to facilitate increased production capacity. However, the new location was further away from the plant’s water supply.
