In September 2021, the Veszprém wastewater treatment plant engaged Sanitaire to provide diffuser liquid cleaning service, which uses formic acid injected into the main aeration pipe to clean the diffuser membranes while they are operating.

In 2002, the EPA entered into a federal consent decree with MSD, mandating the elimination of sanitary sewer overflows and significant mitigation of combined sewer overflows into receiving waterways. Engineers estimated the cost to mitigate the sewer overflows at $3.1 billion, an unacceptable capital expense to pass along to MSD’s customers.

About an hour south of Atlanta, the city of Barnesville, Georgia is a town of shady, tree-lined streets, a fondness for celebrating its history, and a sharp eye on the future. In 2013, as its 30-year-old wastewater treatment plant was reaching the end of its useful life, Barnesville found itself planning for a future of growth, progress, and a new, state-mandated <0.6 mg/L total phosphorus (TP) wastewater discharge limit.

Tasked with transferring water from settling ponds to a frac pond for project in mid-Western U.S., a specialist water provider to oil and gas drilling companies needed a pump capable of handling a complex operation through a seven-mile-long steel pipeline.

Dŵr Cymru Welsh Water’s Hirwaun water treatment works is a small works (5Ml/d) which treats raw water from the Penderyn upland reservoir. Treatment is by coagulation with ferric sulphate and lime, flocculation and clarification by DAF. The clarified water is dosed with lime and this is followed by first stage filtration in four rapid gravity filters, intermediate electrochlorination and orthophosphoric acid dosing, and second stage filtration in four pressure filters. Final disinfection is by electrochlorination. The original electrochlorination plant was an Evoqua OSEC® packaged unit installed over twenty years ago and had reached the end of its asset life.

While water utilities are balancing daily operations, they’re also facing wide-ranging challenges that makes strategic planning, funding and technology even more important. Short-term solutions are no longer an option – solution longevity is a priority.

A large UK private utility company responsible for providing public water supply and wastewater treatment to the majority of southern England recently approached Xylem to enquire about what it could offer to improve or restore the performance on their Sanitaire fine bubble diffused aeration systems.

Faced with high standards for both efficiency and sustainability, Averdung and the municipal utility sought a partner capable of realizing this supply through seawater source heat pumps using Baltic Sea water.

India has a water distribution problem, brought about by climate change, rapid industrialization, a growing population and a water supply network that has not kept up with demand. Currently, the water supply is often rationed across different districts by “key turners,” who turn it off for hours a day.

EMASESA (Empresa de Abastecimiento y Saneamiento de Aguas de Sevilla S.A.) is responsible for water cycle management in the Spanish city of Seville and its metropolitan area. The utility supplies approximately 100 hm3 of drinking water to 1.4 million residents in 12 municipalities every year, as well as distributing raw water to 31 municipalities, serving a total area of 1,220 km2. It manages a 4,000 km network, six water reservoirs, 35 pumping stations...

This guide, developed in partnership with AWWA, explores how utilities can adopt data-driven pipeline management strategies and features real-world utility success stories. Learn more about assessing pipelines and leveraging data to prioritize and address risk.

At the start of 2021, the plant registered a decrease in air flow, accompanied by an increase in energy consumption by the blowers. Personnel suspected that the diffusers were clogged by calcium carbonate build-up from the water, causing significant head loss in the diffusers.

In 2016, EPAL recognized a deviation in the non-revenue water (NRW) trend since implementation of the DMA program. The issue was promptly identified in two supply zones, encompassing 150 kilometers of water transmission mains, predominately composed of large diameter reinforced concrete pipe built in 1965.

Nestled in between Lake Lanier and the Appalachian Mountains, about an hour north of Atlanta, is the Etowah Water & Sewer Authority (the Authority). Chartered in 1980 with a mission to improve the quality of life for its customers, community and the environment through proper management of water resources, the Authority serves 5,400 consumers and runs 1.5 million gallons of water per day through 175 miles of pipe.
