Pittsburgh, Pennsylvania property owners must meet municipal and authority requirements before connecting buildings to the public sewer system. This guide summarizes who is responsible, typical permit and inspection steps, common technical rules, and how enforcement works under Pittsburgh city law and local sewer authority policies. It is intended to help owners prepare applications, hire licensed contractors, and respond to inspections or notices from the City or the Pittsburgh Water and Sewer Authority (PWSA).

Who is responsible

Property owners are typically responsible for the private sewer lateral from the building to the public sewer main, including maintenance, repair, and connection compliance. Contractors performing work usually must hold appropriate city and state licenses and obtain permits where required. Check the city code and PWSA requirements for exact responsibilities and allowed materials.[1]

  • Owner responsibility: private lateral repair, replacement, and connection compliance.
  • Licensed contractor required for most sewer connections and lateral work.
  • Permits and inspections must be scheduled before work begins.
Confirm whether your property lateral is private or public before hiring a contractor.

Technical requirements and standards

Sewer connections must meet material, slope, and backflow prevention standards set by the city code and local authority procedures. Typical items reviewed in an inspection include connection watertightness, correct grade and bedding, removal of illegal connections, and presence of required cleanouts. Specific technical specifications and approved materials are provided by the enforcing authority and referenced in permit instructions.[2]

  • Inspection checklist: watertight joints, slope, cleanouts, and backflow devices where required.
  • Materials: approved pipe types and fittings per authority standards.
  • Prohibitions: no illicit connections of stormwater or prohibited wastes to sanitary sewers.

Penalties & Enforcement

Enforcement is carried out by the City of Pittsburgh and the Pittsburgh Water and Sewer Authority (PWSA). Exact monetary penalties, daily continuing fines, and fee schedules are referenced in the municipal code and PWSA rules; specific fine amounts and escalation ranges are not specified on the cited pages and may be set in ordinance schedules or authority tariffs.[1] For compliance actions, inspectors may issue notices, orders to repair or disconnect, and may refer unresolved violations to civil court.

  • Fine amounts: not specified on the cited page; see official ordinance or authority tariff for numeric penalties.
  • Escalation: first, repeat, and continuing offences may carry escalating remedies; specific ranges not specified on the cited page.
  • Non-monetary sanctions: repair orders, disconnection orders, lien or civil court actions, and stop-work orders.
  • Enforcer and complaints: PWSA and City inspection divisions handle complaints and inspections; contact details are provided in Resources.[2]
  • Appeals: appeal or review routes may be available through administrative hearings or municipal court; time limits for appeals are not specified on the cited page and should be confirmed with the enforcing office.
If you receive a repair or disconnection order, act promptly to avoid escalation and additional costs.

Specific form names, numbers, fees, and submission methods vary; where a form name or fee is not shown on the authority page it is not specified on the cited page. Always confirm current forms and fee schedules with the issuing office before submission.[2]

  • Plumbing or building permit: apply through the City permitting office; fee amount may vary by scope.
  • Authority connection/inspection request: submit per PWSA instructions; fees and form names referenced on authority pages.
