The New Hampshire Department of Environmental Services (NHDES) offers the Lead Service Line Inventory (LSLI) and Replacement Plan Grant for Large Community Water Systems. This initiative provides grants ranging from $50,000 to $100,000 to support communities in completing lead service line inventories and replacement plans. The grants are designed to accommodate various service connection sizes and do not require a community match, although the total project cost may exceed the grant amount, with only the grant amount reimbursed. The program operates on a first-come, first-served basis, with the final deadline for completing inventories and replacement plans set for October 16, 2024.
