Aqua’s Pennsylvania region is executing an active water main renewal program that includes both replacement of water mains as well as cleaning and cement mortar lining of unlined cast iron pipe. In 2012 alone, the utility spent $259 million on infrastructure improvement projects in the state, including the replacement or cleaning and lining of 140 miles of aging water main. Such projects are critical to ensuring water quality, service reliability, and increasing firefighting capabilities.
After a public company partners with a private water system, one of the greatest challenges can be prioritizing a huge backlog of infrastructure improvement projects. In evaluating how to best accomplish this, Aqua Pennsylvania recognized that it needed to develop a more formalized and efficient approach to prioritizing renewal projects. To address this, Aqua Pennsylvania implemented two technology-based, information management initiatives in its Pennsylvania subsidiary. The first, Asset Information Management System (AIMS), is a web-based platform that allows employees to retrieve information on pipes, hydrants, main breaks, and customer taps. It also provides a link to more than 50,000 scanned images of construction as-built plans, providing "one-stop-shopping" for distribution system information.
A second information management system, geographic information system (GIS) allows users to visually retrieve and display much of the same information as AIMS using a map-based system. Weekly updated maps are generated from the GIS and are made available to users as Adobe PDF images via AIMS. In addition, simple viewers are created that provide a live view of the GIS database. The viewers are easy to use, do not require sophisticated training, and are deployed using free software.
With an insurmountable amount of data to work with in the region, AIMS and the GIS provide Aqua Pennsylvania with the tools needed to prioritize its water main renewal program effectively and efficiently.
