Pennsylvania settles this at a level below the county. The permit does not come from the state, and usually it does not come from your county either. It comes from your municipality, through one certified official.

The Bureau of Clean Water administers the wastewater management programme opens in a new tab and the sewage facilities programme exists to implement the Sewage Facilities Act, known as Act 537 opens in a new tab. The on-lot portion is largely administered at local government level by individual municipalities, or groups of municipalities working together opens in a new tab.

The term that matters is local agency, and it is broader than it sounds. A local agency is a municipality, or a combination of municipalities acting jointly, or a county, county department of health or joint county department of health opens in a new tab. So a county health department can hold the role where one exists, and most of the time the municipality does.

Municipalities are required to develop and implement comprehensive official plans that resolve existing sewage disposal problems opens in a new tab. That obligation is why your township has a sewage plan at all, and why the answers differ once you cross a municipal line.

The certified figure in Pennsylvania is not the installer. A sewage enforcement officer is an official of the local agency who reviews permit applications and planning modules, issues permits and conducts the investigations behind them opens in a new tab. They work for the regulator, not for the contractor.

That role is the gatekeeper for every permit in the state. No local agency may issue a permit for an onlot system except by and through a certified sewage enforcement officer employed or contracted by it opens in a new tab, and nobody may issue such a permit unless they have been found qualified opens in a new tab.

Certification runs through a board created by the Act itself. Act 537 created a State Board for Certification of Sewage Enforcement Officers within the department opens in a new tab, and questions about certification or continuing education go to the Secretary of that board opens in a new tab.

For installers the picture is different, and it is worth being exact about it. Penn State records that certification for septic system installers, inspectors and waste haulers is provided by the Pennsylvania Septage Management Association opens in a new tab, which is a trade association rather than the Commonwealth. We found no Pennsylvania state licence or certification for septic installers.

What the state does register is contractors in general, and it is candid about what that means. Any contractor performing at least 5,000 dollars of home improvements a year must register with the Attorney General opens in a new tab, and the same office says that registration is not an endorsement of their honesty or quality of work opens in a new tab.

Pumping is registered separately and by the state. The Solid Waste Management Act requires any individual or organisation that pumps septic tanks or hauls septage to register opens in a new tab with the department. That register is the one we check Pennsylvania companies against, so a verified mark here means the hauling side and says nothing about installation.

Permits, Inspections and Selling a Home

Nobody may install, award a contract for, or construct an onlot system without a permit opens in a new tab, and a permit is also required for alterations or connections to an existing one opens in a new tab. The permit comes from the local agency, which means the municipality in most of the state.

The soil is tested before anything is approved, and the testing is unusually prescriptive. Soil tests establish the presence of a limiting zone and the capacity of the soil to pass water opens in a new tab, and six or more percolation tests must be made in separate holes spaced uniformly over the proposed absorption area opens in a new tab.

Pennsylvania has one rule that catches buyers of older rural property. No permit is required for a system serving a single residence on a lot of ten acres or more opens in a new tab in defined circumstances, so such a system may never have been permitted at all. Act 537 answers that with a disclosure duty: every contract for the sale of a lot with no community sewage system available must carry it opens in a new tab.

We found no Pennsylvania rule requiring a septic inspection when a home sells. What does apply is disclosure and local practice: a seller must disclose any material defects in the property opens in a new tab, and some municipalities require a local sewage enforcement officer or certified service provider to carry out routine regulatory inspections opens in a new tab. A malfunction has a narrow definition too, since an officer generally treats a system as malfunctioning only where wastewater is visibly emerging at the surface opens in a new tab.

Pennsylvania's own municipal standard is tighter than the general advice: a sewage management programme must require removal of septage from treatment tanks once every three years opens in a new tab, and those programmes are enacted by municipalities to assure operation and maintenance opens in a new tab. DEP itself puts the interval at least every three to five years opens in a new tab, as does the EPA opens in a new tab.

Pennsylvania lends to the homeowner directly, which is rare among the states written so far. PENNVEST, working with the Pennsylvania Housing Finance Agency, provides low-cost financing to improve, repair or replace a system opens in a new tab. The published terms illustrate a 25,000 dollar loan over a twenty year term opens in a new tab, with origination and closing charges paid by the borrower.

The federal route runs alongside it. Loans may be used for repairs and improvements while grants must be used to remove health and safety hazards opens in a new tab, under the Single-Family Housing Repair Loans and Grants programme.
