AWWA CEO David LaFrance thanks water professionals nationwide for keeping water safe for drinking
Dec. 16, 2014, marked the 40th anniversary of the Safe Drinking Water Act (SDWA), which today includes regulations for more than 90 contaminants. American Water Works Assn. (AWWA) CEO David LaFrance issued the following statement to mark the occasion.
Made of clear, chemical-resistant PVC and reinforced with spiral steel wire for durability, Vardex PVC hose is suited for fluid or air transfer and handles both pressure and full vacuum. Applications include chemical transfer, air supply, coolant feeds, floor cleaning equipment, material handling, water feeds and discharge, vacuum lines, spray systems, and food and beverage supply lines.
Utah State University study validates the performance of PVC pipe used in water networks
The Utah State University (USU) Buried Structures Laboratory has published a comprehensive study on PVC pipe excavations, testing and lifecycle analysis. USU, located in Logan, Utah, is also home to the Utah Water Research Laboratory and has contributed to water and wastewater research internationally for more than 50 years.
Rainwater harvesting and storm water recycling are similar processes, but rainwater harvesting usually involves collecting water from cleaner surfaces, such as roofs, while storm water typically is ground-level runoff. Both require collecting, storing and conserving rain for later use.
Rainwater harvesting system provides alternative to well water
In about 1965, a specially designed plastic pipe, termed truss pipe, was introduced in sizes of 8-, 10-, 12-, and 15-inch diameters. In 1967, a British manufacturer announced the production of extruded polyvinyl chloride pipe (PVC) in diameters up to 16 inches, with the future possibility of producing up to 30-inch pipe. These developments undoubtedly will lead to the wider use of plastic pipe for sewers.

The City of Las Vegas has joined other large urban areas in the move toward rehabilitation of its aging infrastructure. Recently the city renewed its Sloan Lane Interceptor — a renovation utilizing more than 12,500 ft. of 40-in., 45-in. and 51-in. Hobas centrifugally cast fiberglass reinforced polymer mortar (CCFRPM) pipe to slipline the deteriorating reinforced concrete pipe (RCP) host.
