While the use of lead pipes in new construction was prohibited in the United States in 1986, much older homes still receive water through lead pipes, which are considered considerable care for public health due to the potential for water pollution in drinking water.
Last fall, the Environmental Protection Agency (EPA) launched the rule to improve olov and copper, which requires almost every water water pipe in the country to be eliminated by 2037.
In Wilmington, Delaware has approximately 74,000 service lines, and the excavation and replacement of all of them would be expensive and intense over time.
The University of Water Resources Center, UDWRC), the city of Wilmington and Jacobs, a private engineering company, partnered to create the first of its own leading inventory for all water lines owned by the city. So instead of replacing all 74,000 lines, the city will be able to focus its resources at less than 2000.
The findings of the analysis have shown that 75% of the system are not leading. It was found that less than 2000 -less than 3% -were made of lead, and less than 1000 lines were made of galvanized materials.
The development of this inventory has significant public health and economic benefits for Wilmington residents. Determining the materials of the drinking water service lines and the determination of the areas in which lead and pipes are to be replaced reduces uncertainty, while reducing the estimated cost of replacing lead lines in the historical system of the city.
“This partnership not only guarantees compliance with federal regulations, but also serves as a model for cities across the country,” says Kelly Williams, Commissioner for Public Affairs in Wilmington. “We are proud to have set an example of what the cooperation between municipalities and academic institutions can achieve.”
Martha Navaes, an associate director of UDWRC, and Andrew Homsi, Geographic Information Systems (GIS) manager, have run the initiative that has been going on over the last two years. Narvas and Homsi controlled a team of UD students – covering four colleges and eight specialties – who have reviewed more than 70,000 historical work contracts dating back to 1916 to describe the public side of Wilmington’s water supply.
The team evaluated the data on the service line from the city plans, an asset management system, a measuring instrument shop, licensing and inspection and insurance records. Students searched hand -written work orders from the beginning of 1900 and updated GIS mapping layers to identify critical information such as service materials, size, location and date of installation. Jacobs further processes the data using AI techniques to help in the quality control process.
“The initiation and hard work of the students were remarkable,” Williams said. “Their ability to review carefully over a century of data to develop our map of the Inventory of Services is nothing but extraordinary.”
Inventory will help the city of Wilmington to meet the deadline for reviewing EPA and copper rules, according to Cheryl Townsend-Braun, a specialist in business analyst/assets management at Jacobs.
“The careful review of students for historical work contracts not only provided the basis of the inventory of the water service line in the city, but also provided immediate and tangible benefits to our community,” she said.
Using this data during water replacement projects, the city has already saved thousands of dollars using grants financing instead of funding for capital to replace water services, Townsend-Braun said.
“We are extremely grateful for the hard work and the dedication of students, whose efforts have had a lasting impact on both public health and the financial management of the city,” she said.
Three student researchers – Aaron Balmer, Cooper Fenny and Dmitry Ribin – presented their findings at the annual meeting of the UDWRC Advisory Panel last May. The consultation panel includes representatives of the University of Delaware, the State University of Delaware, government agencies and non -profit water resources organizations in Delaware.
“This project is extremely rewarding both personal and professional,” says Fayeni, a higher economy and a specialty public policy. “By contributing to such an important aspect of compliance with the EPA regulatory regulators, while I have the opportunity to present my discoveries and to inform other researchers and professionals of its importance is a major experience in my early career in the research and policy of water resources.”
Other student researchers included Lydia Franks, Alex Makovski, Elizabeth Shields, Megan Vasil and Michele Wacil.
UDWRC will continue to work with students, the city of Wilmington and Jacobs to describe approximately 18,000 city lines that have not yet been identified.
“This partnership serves as a state and national model for other cities and cities that must meet the EPA safe drinking water standards to provide the public with clean and healthy drinking water,” Narvas said.
The results of the original inventory are available through the city website on the Wilmington Water Website. Wilmington seeks help to customers in identifying their private service lines and encourages residents to participate in the study of the water service line.
For the Institute of Public Administration
The Institute of Public Administration of the University of Delaware (IPA) addresses the needs of the policy, planning and management of its partners by integrating applied research, professional development and education of tomorrow’s leaders. As a Center for Research and Public Services in Joseph R. Biden, Jr. School of Public Policy and Administration, IPA collaborates with state agencies, municipal governments, non -profit organizations, communities and enterprises for the study of complex political issues and improving the quality of life in Delaware and beyond. As one of the main IPA programs, UDWRC has efforts to protect and provide water supply, management and quality.
