Commitments [Abstract]
Commitments	8. Commitments The Company was granted approval by the Pennsylvania Public Utility Commission, or PPUC, to modify its tariff to include the cost of the annual replacement of up to 400 lead customer-owned service lines over nine years from the date of the agreement. The tariff modification allowed the Company to replace customer-owned service lines at its own initial cost. The Company recorded the costs as a regulatory asset to be recovered in future base rates to customers, over a four-year period. The cost for the customer-owned lead service line replacements was approximately $2,093 and $2,087 through March 31, 2026 and December 31, 2025, respectively, and is included as a regulatory asset. The tariff modification expired on March 8, 2026. The Company has filed a Lead Service Line Replacement Plan with the PPUC and is awaiting a decision. If approved, the plan would establish the requirements for, and the associated cost recovery mechanisms related to, the future replacement of customer‑owned lead service lines.
