Public utilities report: lead-service-line sampling expands; Elamir treatment design begins
Summary
Arcadis completed 400 test pits for the city's lead-service-line inventory and will expand sampling toward about 1,200 sites; Hazen & Sawyer was contracted to start design work for the Elamir Water Treatment Facility with a conditional assessment and preliminary report over the next six months.
Director of Public Utilities William Norton reported progress on the lead-service-line inventory and on water-plant design work at the committee's May 19 meeting.
Norton said Arcadis has completed the initial 400 test pits needed to create an analytical model for the inventory. "Once that's done, we'll have to move on to the next phase," Norton said, describing plans to sample additional master meters, child facilities and schools and to complete roughly 800 more test pits for about 1,200 sample sites. Norton said the city's goal is to verify the system is lead free; if the initial model does not verify that, the scope could expand significantly — "If not, we'd have to do 16,000 test pits," he said.
Norton also reported the city signed a contract with Hazen & Sawyer to begin design work for the Elamir Water Treatment Facility; the contract includes a conditional assessment and a preliminary report expected over the next six months, after which staff will proceed toward a fuller design.
Committee members asked about timing for temporary water lines and the schedule for putting treated water back into system piping; Norton said final test results for certain streets were expected within days and that he anticipated normal water flowing through temporary mains by the following Monday or Tuesday, contingent on lab results.
No formal action was taken; Norton closed by offering to answer member questions and to return with updates as the design and sampling programs progress.
