In order to ensure municipal water demands were met, the city of El Dorado, Arkansas contracted with Tanner Engineering & Carter-Burgess to design five new deep wells, water transmission mains, ground storage tanks, pump station, and chlorination facilities. In order to complete the project before the sultry days of summer, the municipality and engineering firm decided to save time and energy by installing a modular pumping system.
Monterey Regional Water Pollution Control Agency (MRWPCA) has installed a new type of pump featuring a unique, self-cleaning impeller to overcome frequent clogging experienced in recent years at Pacific Grove Station 12. Prior to replacing the station’s two original pumps, the wetwell’s limited retention and close proximity to Monterey Bay — 60 ft. away — increased the risk of bypasses reaching the beach.
PROJECT DESCRIPTION: To transfer stormwater from a creek to an adjacent river during periods of high water during storms and spring thawing.
For more than 220 years people have journeyed to White Sulphur Springs, W. Va., to indulge themselves in baths of mineral water flowing from mountain springs. As inviting as the sulphur water may be, it is equally harsh on the pipes and pumps that transport it. Eight years ago Greenbrier decided to stop the corrosion once and for all by installing an all-stainless model manufactured by Goulds Pumps.
Stainless steel’s anticorrosive properties help serve up the healing powers of water
In a municipal water supply application in Jamaica, ITT Industries’ Goulds Pumps unit is supplying the pumps and the expertise to improve aging and inadequate water supply infrastructure. These new water supply projects will improve the health of the customers served there by providing clean, potable water.
The Diablo Canyon Power Plant at Avila Beach in California utilizes seawater for both cooling water and makeup water for steam generation. Ionics, Inc., Watertown, Mass., designed and built and now operates a complete water treatment system serving the high-purity water needs of this power plant. Over the past eight years, the seawater treatment section has demonstrated excellent long-term performance as a result of strong design, consistent maintenance and qualified operators.
Since the introduction of the metering pump, chemical feed for disinfection has been a primary application. As we move into the 21st Century, it again is time to review how we introduce chemicals such as sodium hypochlorite into our water systems. While the goal remains the same, changes in pump technology have been created to provide more accurate and consistent results. This article will discuss current metering pump technologies, proper pump sizing, installation and future enhancements.
Motor-driven, solenoid and peristaltic metering pumps provide proper control for specific applications and multiple needs.
The pumps at the Stony Brook Lift Station in Suffolk County, N.Y. used to clog so often that crews anticipated an event as part of their weekly routine.
Typical agricultural, domestic and municipal systems are excellent applications for these motors. Unfortunately, these motors often are used in applications that unknowingly exceed the design criteria of the motors.
The intake system that will draw cooling makeup water from the Kaskaskia River for the $250-million Holland energy plant in Shelby County, Illinois, was designed to balance construction cost imperatives against the river’s variable flow, regulatory requirements and the owner’s operating preferences. The result is a state-of-the-art vital element for the gas-fired, combined cycle plant. As more and more closed-cycle plants are proposed, the concepts that Parsons applied along the Kaskaskia River may provide a good starting point on the drawing boards.
