Ask the owner or current resident for the existing water, sewer, electricity and heating arrangements. A recent bill or the property paperwork is a better starting point than a general service-area list. In a rental, establish which accounts you open and which charges remain with the landlord.
Water
If Southwestern Pennsylvania Water Authority serves the address, use its new-service instructions or call 1-800-356-4168. The authority requires an application and identity information; supply those directly through its process. Confirm approval, charges and the intended start date with the office. The page also discusses new physical water connections, which are a different matter from taking over service at an existing home.
When leaving an existing SPWA-served home, its final-bill instructions ask for a call at least one business day before service should stop. Have the account and service address, requested date and forwarding address ready, and follow the authority's verification steps. Coordinate that date with the handover so the property still has the service it needs.
Sewer and other accounts
The Carmichaels-Cumberland Joint Sewer Authority lists 724-966-5800. Confirm whether it serves the property, who holds the account and whether a change of occupant requires separate notice. Do not assume a water application changes every associated bill.
For electricity, heating and internet, record each provider, account holder, start or stop date and any appointment needed. Keep confirmation messages together. Before the first night, check that the home has the essential services you expected and a clear route to report an account or connection problem.
