The current economic climate has forced many state and local governments to face budget cutbacks and service reductions. This situation often translates to a reduction in the replacement, repair, or upgrade of aging pipelines, tunnels, reservoirs, and dams. As a result, many water districts are turning to software technology for an efficient yet cost-effective way to protect the water supply.
Replacing the London Water Supply SCADA System

Neil Parker, B.Sc., C.Eng., MICE, CIWEM
For Thames Water, managing the process of water abstraction through to delivering treated water to more than five million customers in London involves plant control at more than 150 locations. Most of these are unmanned as the London Water Supply (LWS) supervisory control and data acquisition (SCADA) system carries remote control signals to operate the plant and to monitor its status. The move to a new system was driven by the increasing business need to be able to share data within the SCADA system with other operational and management information systems.

Rodney Johnson
Detroit Water & Sewerage Department (DWSD) has a high stake in keeping its flowmeters up and running with calibrated accuracy. This is especially true for its 278 wholesale water meters used in its vast network of distribution lines that serve 126 communities. It also is true for metering sewage inputs from wholesale customers for its Wastewater Treatment Plant. This article focuses on a unique answer that DWSD found for keeping its magnetic meters online by means of a portable electronic system that verifies and certifies calibration, all done in-line.

Rapid changes in technology make it vital for small utilities such as Wrightstown to update their systems. IPMC software components make it easy to update, integrate and expand the applications. Non-proprietary software helps ensure that data will be available and usable with existing or future system software. Data preservation in an open architecture format allows for data migration to other software applications as may be required when working with an engineering consultant.

Lorraine Keating, Prism Visual Software
The media predicts that virtually all work as we know it soon will be Web-based and wireless. With the proliferation of PDAs and cell phones, and with their continually decreasing costs, this statement is hard to refute. An article published in Software Technology magazine stated that to characterize this new technology as a "revolution" is an understatement. Rather it is a "cataclysmic change."
