Maintenance and performance of pressurized water distribution systems require a complete grasp on the pressure ratings of every component within the system. Mueller gives valuable insight here for pressure rating standards needed for flanged valves.
From Nevada to South Dakota and now Tennessee, cities across the U.S. are installing the AMERICAN Flow Control® ALPHA restrained joint, because it saves labor, time and money. Introduced almost a year ago, ALPHA is used on AMERICAN’s Series 2500 4- to 12-inch Resilient Wedge Gate Valves and American-Darling and Waterous fire hydrants.
Pump Station #8 was outfitted with old equipment and operation and reliability had become problematic. It was time to turn over a new leaf and embrace new technology to solve the problem.
Winchester Municipal Utilities (WMU) faced challenges regarding two separate sections of town. The lines required maintenance due to old inoperable inline valves that needed to be replaced. The challenge - replacing these valves using a procedure that eliminated the shutdown of the water lines that service hundreds of homes and businesses.
Buchanan County had a project which required repairs to a pumping station that boosts the pressure high enough to get water to a tank at the top of a mountain. The line pressure needed to accomplish this is 250 psi. After considering options, Buchanan County selected the Hydra-Stop Insta-Valve 250 Patriot. Read the full project profile to learn more.
The Ypsilanti Community Utilities Authority (YCUA) employs a total of 30 mixers in its aeration tanks as part of an anoxic nutrient removal process, and the mixers were failing. The mixers were old, inefficient, and starting to fail, so YCUA elected to replace them with Flygt 4320 mixers. Read the full case study to learn how the potential energy savings for YCUA could easily approach $1 million over a decade.
A key driver of economic development is the availability of water and wastewater services. For the Town and Village of Champlain, NY, this is no exception. To capitalize on the region’s economic potential and make more land available for new businesses, the Town and Village of Champlain are working together on the Shared Water Project, a major water system upgrade that includes installing 44,000 feet of AMERICAN ductile iron pipe.
Once discovering its main pump station was at risk, a critical Canadian wastewater treatment plant quickly set up a large bypass pumping system to allow the replacement of pump motors.
Call it what you want, but a busted pipe spells nothing but T-R-O-U-B-L-E.
More than 6,800 cubic yards of structural concrete are being used in the construction of a new Trickling Filter and Trickling Filter Pump Station in Bismarck, North Dakota. These structures are being built well below the area’s water table, and the more than 6,800 cubic yards of concrete will protect them against the effects of Mother Nature.
In Iowa, where agriculture is a critical component of the state’s economy, rain is good for crops, but too much rain is not good for anyone. In 2008 the Des Moines Metropolitan Wastewater Reclamation Authority (WRA) retained consulting engineer HDR to provide planning, permitting, design, construction, and start-up services for a high-rate CSO treatment facility called the Combined Sewer Solids Separation Facility or CSSSF.
The hassles of pump ragging lead a South Carolina Public Service District to change out problematic pumps for Flygt N3171 submersibles.
