The source of the contaminated water was located approximately 250 meters away from the municipal well, at a former industrial site. Upon learning of the elevated test results, the state issued a “do not drink” order to the 450 residents served by the municipal water supply until the water source could pass quality testing again.

Clayton County Water Authority (CCWA) is a good example of a utility that doesn’t let a confined geographical footprint stop it from thinking outside the box. As one of Georgia’s smallest counties in terms of land size area (only 143 square miles), its location near the top of a regional watershed means it has little area to gather precipitation into streams and rivers.

The Empresa Municipal de Aguas de La Coruña (EMALCSA) manages the water cycle in the city of A Coruña and seven neighboring municipalities, serving a total population of 400,000. The utility collects, treats and distributes over 36 million cubic meters of drinking water to 138,000 customers each year, via a network of over 560 kilometers, 26 storage tanks and six pumping stations.

EMASA (Empresa Municipal Aguas de Málaga S.A.) is the Malaga City Council’s public utility which has been in charge of managing the entire urban water cycle since 1987. The company serves more than 600,000 residents and supplies approximately 42 hm³ of drinking water. The system operates at a flow rate of up to 2 m³/s, ensuring urban water supply through an extensive pipeline network of around 2,000 km, divided into approximately 240 DMAs (District Metered Areas) and equipped with over 240,000 meters, 170,000 of which are smart devices.

For many years, irrigation in the building sector was considered a secondary matter. A necessary system, certainly, but rarely a strategic one. Today, that approach is no longer sustainable. Climate change, water scarcity, rising energy costs and increasing environmental responsibilities are radically transforming the way buildings are designed and managed.

California Water Service Company had acquired another water company with approximately 100 connections, in Porterville, California, located in a remote agricultural area of the Central Valley.  Their annual well testing had shown levels of nitrate at or near the Maximum Contamination Level (MCL) of 45 ppm and perchlorate was found in the groundwater at levels above the Public Health Goal (PHG) of 10 ppb. A treatment system was needed to remove both these contaminants to ensure quality potable water for the local community.

Municipalities are often faced with VOC contamination of their source wells. Chemicals like Vinyl Chloride and Trichloroethylene can leach into aquifers used as source water for municipal wells. When this occurs, in many cases the most cost-effective solution is to treat the water to remove the VOCs using air stripping, which has been established as a Best Available Control Technology BACT for this application.

In February 2020, the California State Water Resources Control Board announced revised drinking water Response Levels for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) in drinking water. The new Response Levels (RLs) were set at 10 parts per trillion (ppt) for PFOA and 40 ppt for PFOS. The previous RL was 70 ppt for a combined total concentration for the two contaminants.

A public water agency in California contacted Xylem to treat remove arsenic from a groundwater supply. They needed to achieve a 1 ppb effluent level from the treatment system, 90% lower than the current drinking water standard in California. In addition they needed to have the treatment operating within weeks.

The 34 MGD Otay Water Treatment Plant in San Diego, California serves a population of approx. 200,000. The plant receives raw water from two sources - imported water from the Colorado River and runoff from three local reservoirs.

Santa Clarita is located about 35 miles north of Los Angeles. The Santa Clarita Valley Water Agency (SCV Water) services nearly 74,000 customers and obtains about 50% of its drinking water through local groundwater aquifers. Positioned behind the William S. Hart community baseball and softball fields three two-vessel systems have been installed to remove PFAS from drinking water.

Xylem Vue helped Stadtwerke Trier optimize renewable energy use in its drinking water network, achieving 90% self-consumption.
