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.
As the latest addition to Hydra-Stop’s award-winning Insta-Valve family of solutions, customers with 20- and 24-inch pipes can now benefit from the only insertable gate valve with the superior performance and reliability you would expect from the Insta-Valve name.
Compact, high performance dry chemical blending system utilizes blower-assisted conveyance system to transport and disperse the dry polymer prior to wetting. The wetting technology reduces plugging. The equipment is built from stainless steel to withstand extreme conditions and harsh environments.
Dynablend™ liquid polymer blending systems are proven to be the most effective and reliable hydraulic polymer activation technology. The L4 and L6 are the smallest Dynablend units and the use of a peristaltic pump makes them the most economical of the Dynablend™ blending system. Patented Hydroaction technology follows the science of polymer activation. Two-stage mixing with the highest energy applied first at the moment of initial wetting (MIOW) followed by a "quiescent" zone allowing for more gentle activation as polymer science dictates.
Mueller® Lineseal® 350 Butterfly Valve offers 350psi operating pressure, under flow conditions of 16 ft/sec up to temperatures of 250°F and meets the design criteria for AWWA C504. This valve is available in sizes 6” – 36” for mechanical joint ends and 6” – 48” for flanged ends. This product adds to the Company’s existing line of 350psi products which includes resilient wedge gate valves and Super Centurion® fire hydrants.
A simple valve package that saves both water and money, the Model 106 / 206 PGM-2PR-630-SM is an extension of the 2PR-630 pressure management valve with safety back-up.
The Hydra-Stop 4” – 8” and 10” – 12” Alignment Gauge Kits allow Hydra-Stop Insta-Valve equipment owners increased crew safety and productivity by simplifying the valve cartridge alignment process. In three steps – align the cartridge, set the depth, and lock the cartridge in place – users can swiftly setup for final cartridge insertion. No guessing or measuring required. Reliable and repeatable valve insertions every time.
The Insta-Valve 250 Patriot insertion valve provides an immediate control point in distribution systems, without using a system-wide shut down. Installed under pressure, up to 250 psi, the Insta-Valve 250 Patriot increases operator safety, limits environmental impact, and saves up to 100% of the costs related to system shutdown.
Nicole George, Product Manager - Pumping Variable Frequency Drives with Eaton, starts this Water Talk discussion with a description of the Internet of Things (IoT) before going deep on capabilities, particularly with pumping systems and variable frequency drives (VFDs). Learn how IoT-enabled pumps can help manage operation more efficiently and save on labor costs with cloud-connected, VFD-powered data analytics and health monitoring.
When it comes to infrastructure design or redesign, understanding hydraulic conditions — for all foreseeable scenarios — is paramount. You might call it "test driving" your facility.
There are lots of applications in the water and wastewater industry that need backflow prevention. Stormwater drainage systems are a perfect example. As Mike Duer, Chief Engineer with Red Valve Company explains in this Water Online Radio interview, “water will backflow through the drainage pipe at high tide, come up through the inlets and cause flooding.”
Realizing energy savings with blowers is a big deal in the wastewater industry right now as utilities try to reign in their energy costs. As Paul Nelson, North American Sales Manager for Egger Turo Pumps points out, the next focus area is going to be energy savings with pumps and valves.
Retrofitting your existing S&L Pump Station with new components can give it new life. In fact, you just might retire before it does.
