Fraser Coast Regional Council (FCRC), through Wide Bay Water (WBW), a commercialized business unit of the Council, maintains numerous water supply schemes throughout the region, including remote reservoirs. Reservoirs offer security of potable water supply to the community despite seasonal demands. Additional chlorination may be required to ensure the Australian Drinking Water Guidelines are met. 

The small unincorporated township of Stratmoor Hills is located in the foothills of Cheyenne Mountain in Southern Colorado Springs. It offers its residents stunning views, a lively cultural mix, and a convenient commute to the Fort Carson U.S. Army installation, making it a popular place for military families to live. The community’s water security is the responsibility of the Stratmoor Hills Water District (SHWD), which oversees a combination of surface and groundwater sources.

Like many communities in the desert southwest, Phoenix, Arizona's water supply includes wells with arsenic concentrations exceeding 10 ppb. Long before the USEPA revised the arsenic rule from 50 parts per billion (ppb) to 10, the City of Phoenix began bench and pilot scale studies for arsenic removal options. Early investigations focused on well-known processes like activated alumina and ion exchange as well as less proven concepts such as coagulation-assisted microfiltration.

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.

Klomac, the Southern African agent for Wallace & Tiernan® products, has successfully completed the supply and installation of chlorine and ammonia dosing equipment at Rand Water’s Mapleton Pumping Station as part of that station’s upgrading and expansion programme. The Wallace and Tiernan equipment includes four Model V2000™ automatic chlorinators rated at 40 kg/h each, four ammonium hydroxide dosing pumps and GMS chlorine gas leak detection equipment.

Northumbrian Water provides water supply and sewerage services to a population of 2.7m in the north east and 1.8m in the south east of England, delivering 1,100 MLD of drinking water. Potable water treatment works vary from small groundwater sources to large surface water treatment facilities. Their Mosswood Water Treatment Works in County Durham treats 135 MLD of water by clarification, filtration and chlorination.

The Water Division provides continuous high quality water to approximately 43,500 that call Moline home. It utilizes the Mississippi River as its source to treat, pump, and meter water to over 17,000 homes and businesses. The variable quality of the water in the Mississippi source poses unique treatment challenges to the Water Division. Moline’s LT2 water study revealed that significant levels of Cryptosporidium are periodically present in the source water.

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.

SES Water supplies 160 million litres of clean water daily to over 735,000 people in the UK across parts of Surrey, Kent West Sussex and South London. Westwood Water Treatment Works in Surrey is central to keeping its supply of water safe for local residents.

The Santa Clara Valley Water District (the District) manages an integrated water resources system that includes the supply of clean, safe water, flood protection, and stewardship of streams on behalf of Santa Clara County's 1.8 million residents. The district effectively manages 10 dams and surface water reservoirs, three water treatment plants, an advanced recycled water purification center, a state-of-the-art water quality laboratory, nearly 400 acres (162 hectares) of groundwater recharge ponds, and more than 275 miles (443 km) of streams.

First settled in 1836, the City of Berea, Ohio gained acclaim as being the source for dimensioned stone formed from locally quarried sandstone, notably grindstones. The grindstones were shipped to Cleveland by oxcart and, as demand grew, later by a purpose-built railroad to the Big Four Railroad across the Midwest. Now many of the former quarry pits are better known as Baldwin Lake, Wallace Lake and Coe Lake.

The water supply system in Zurich supplies approx. 850,000 people in the city of Zurich and in 67 nearby municipalities with high-quality drinking water at all times. On average, 151,200 m3 of water are consumed each day, the entire water supply network is 1,542 km long (Figures: 2010).

Located in Southern California, this water utility uses wells to store water. These same wells are also used for fire protection. which is especially critical during the summer months. The supply covers about 10,000 customer connections with chloraminated water for residual disinfection, with chlorine and ammonia boosting in various locations.

Whilst residual chlorination is relied upon to provide protection of drinking water in distribution systems, it is increasingly being supplemented by ultraviolet (UV) irradiation as a primary disinfectant for drinking water treatment. As a chemical-free process it avoids many of the issues associated with hazardous oxidising disinfectants and does not generate disinfection by-products. It is also effective against microbiological pollutants such as protozoa, that are resistant to chlorine.

The consulting engineer for a municipal water utility contacted Carbonair to solve a problem that their client was having with several of its drinking water production wells. Low levels of Vinyl Chloride (VC) were detected in several of its drinking water wells. They needed to treat this water on a temporary basis until they could either construct new wells or build a larger permanent treatment plant to handle the problem.

A UK water supply company serves a population of approximately 675,000 consisting of homes and businesses in Surrey, Sussex and Kent and is a key part of London’s drinking water network. The largest works in Kent, which takes raw water from a reservoir that is recharged in winter by abstraction from the River Eden. The original works capacity was 35Ml/d and it is currently undergoing a phased uprate.

The Weaverville Community Services District (CSD) is a publicly owned municipal water agency located in Weaverville, California. The facility needed to retrofit an existing building and switch from a gas feed system to an onsite hypochlorite system. The conversion from gas to hypochlorite is a trend being seen in many Northern California districts as regulations on chlorine gas increase.

Irish Water was created by the Irish Government in 2013 and supplies drinking water to the whole of the Republic of Ireland. The company is investing over €65 million as part of their National Disinfection Programme involving the upgrade and standardisation of disinfection systems currently installed in over 800 sites including water treatment plants, pumping stations and reservoirs.

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.
