Auditors also visit individual homeowners, who, Becht says, often don’t understand how to water properly. “They tend to over-water; there again, the combination of letting them realize the true impact of their behavior on their water costs through a tiered water rate and then showing them what they can do, worked very well together.”

OUC also promotes landscaping with drought-tolerant plants and native species. “Some of the more popular non-native plants are not always the best when it comes to saving water on irrigation,” he adds.

Keeping an Eye on Things
In Jacksonville, FL, the JEA’s Water System won the AMWA Platinum Award for sustained competitiveness achievement in 2006. No small achievement, since the utility supplies water to its customers through a complicated system that extracts water from 150 artesian wells tapped from the Floridian Aquifer, one of the world’s most productive aquifers. JEA distributes water to its customers through an elaborate setup that includes 44 water treatment plants, 3,480 miles of water lines, and over 2,500 miles of collection lines. For JEA, however, the success of this water delivery system lies in its TargetSmart and Metrix programs. By using the TargetSmart methodology, JEA determined that 40% of the water and wastewater work tickets were due to problems located at the customer’s meter or water service. Additionally, the Metrix program keeps an eye on solving system defects. This might include measuring the number of defects involved with a particular process, as well as what should be done to evaluate that process in order to make improvements.

“We are measuring the outcome of the use of our products, and how many defects may be present, as well as those things someone can do to make improvements,” says Suzanne Goss, government relations specialist with JEA. “There are areas within the company where we measure that, and have continued that process for years.”

Eventually, a “water troubleshooter” position was established in order to provide an additional level of personnel able to respond to tickets in a timely manner (24 hours per day), and make the necessary repairs without reassigning the tickets to other crews.

In an effort to enhance the quality of water delivered to its customers, JEA installed six water quality monitors at key locations within the distribution system. The water quality monitors supply real-time information on the status of the distribution system through a Supervisory Control and Data Acquisition (SCADA) system. The parameters that are monitored include turbidity, acidity, chlorine residual, conductivity water temperature, and pressure.

Currently, there are over 75 devices reporting real-time information via the SCADA network. These pressure monitors are used for troubleshooting possible main breaks, inadequate water main design, and unreported valve closures in the distribution system. The goal of using these pressure-monitoring devices is to become aware of a distribution problem before the customer generates a complaint. By proactively monitoring the distribution system, JEA knows if reliable and stable pressure is being provided to their customers. The sensors also provide data for planning purposes, on areas where the infrastructure has deteriorated or not kept pace with development.

In the event a customer has a continual problem with water pressure or quality, JEA has also developed a portable pressure-monitoring station that uses cell phone technology to gather real-time customer service information. Real-time information on water pressure and chlorine residual is gathered and analyzed by the SCADA system in order to bring the customer’s complaint to a satisfactory resolution. Next Page >
