Underwater Testing in the Development of EVA Support Systems
The ability to simulate realistic zero-g conditions on Earth is of prime importance in determining if various orbital operations associated with extravehicular activity (EVA) can actually...
Pioneer Conjunctive Use Program in the Southern San Joaquin Valley
The Arvin-Edison Water Storage District is located in the southern end of the San Joaquin Valley of California. The District is a pioneer in using conjunctive use operations to overcome...
Renewing San Diego Pumping Station No. 64
Pump Station 64 has experienced a number of sewage overflows into Penasquitos Lagoon since 1979 (57 in total). The California Regional Water Quality Control Board (CRWQCB) issued a Cease...
Predicting Equipment Failure
At Cleveland's Westerly Water Pollution Control Center, the physical/chemical plant for treating wastewater is one of the largest of its kind, with 50 mgd average capacity....
Pump Plant Control and Automation
Pumping plants for irrigation systems can be separated into two general types: source pumps which provide water to the system and booster pumps which increase the system pressure. Typically,...
Maintenance of Automated Pumping Plant Controls
Westlands Water District, located in the Central San Joaquin Valley in California (Fig. 1) includes over 600,000 acres of agricultural land and is part of the San Luis Unit of the U. S....
Reliability Analysis of Pumping Stations and Storage Facilities
The methodology presented for pumping stations is based upon three models: a supply model, a demand model, and a margin model. The supply model considers so-called states of a system which...
Top Projects of 1987
Five notable entries in the 1987 Outstanding Civil Engineering Achievement competition are summarized. The Keehi Interchange of the H-1 Freeway in Honolulu is only 1.9 miles long, but...
Sewers Get a Breath of Fresh Air
Domestic sewage pump stations and treatment facilities have long been plagued by corrosion and odor problems caused by hydrogen sulfide. It is also extremely toxic. Sulfide production...
