Edmore staff report one lead service line found; EGLE submission and possible replacements discussed
Summary
Village Manager Mark Borden told the council the drinking-water asset management hydro-excavation identified materials at 98 service locations and found one lead connection; a Complete Distribution System Materials Inventory will be submitted to EGLE by Oct. 16, 2024, and council discussed using grant or ARPA funds for any required replacements.
Village Manager Mark Borden told the Edmore Village Council on Sept. 9 that the village’s hydro-excavation effort identified the material type at 98 water-service locations and found a single service line connected to lead. The village and consultant Fleis and Vandenbrink are preparing a Complete Distribution System Materials Inventory (CDSMI) to submit to the Michigan Department of Environment, Great Lakes, and Energy (EGLE) by Oct. 16, 2024.
Borden said the state-required Drinking Water Asset Management (DWAM) work positively identified materials near curb stops and that the contractor’s low bid for the 98-location hydro-excavation was about $34,000, well under the original engineering estimate of more than $80,000. He said EGLE now allows the village to use leftover grant money to inspect additional locations and that the contractor plans to return in October to dig more sites.
“Only one water service line was connected to lead,” Borden reported. He added that about 50% of the village service lines are galvanized from the curb stop into homes and that the village believes it can show most galvanized lines were never connected to lead by expanding the excavation work. That proof would influence whether those lines require replacement under EGLE’s rules.
Borden said the village is obtaining estimates to replace the single lead-connected service and suggested that ARPA funds previously set aside for water-service replacements would be an appropriate source if additional replacements are required. He cautioned that some smaller 2" galvanized mains are aging and that the village can expect more leaks if the pipes are not addressed.
Next steps include finishing the CDSMI with Fleis and Vandenbrink and submitting it to EGLE by the Oct. 16 deadline. Borden said the village will pursue additional excavations permitted by the grant and will return with cost estimates for any required replacements once EGLE’s determinations are clarified.
