Septic system installation in Biddeford, Maine.

Biddeford runs two public sewer systems: the central system feeding the Water Street treatment plant, built in 1964 and now serving about 15,000 people, and a separate collection system in Biddeford Pool village that feeds a small plant on Stonecliff Road, built in 1989. The University of New England has its own treatment plant. Properties outside those systems rely on private septic, and the city's public facilities chapter lists private systems as outside its wastewater division's responsibility.

We install new and replacement septic systems, including the excavation, tank, distribution and leach field, and finish by grading and seeding the yard.

Permits, the site evaluator and the LPI

In Maine, a permit is needed before installing a new, expanded or replacement subsurface wastewater system. The design comes from a licensed site evaluator, or an engineer for engineered systems, based on a site evaluation, and the local plumbing inspector reviews the application and issues the permit. Work must begin within 24 months of issue, and the inspector gets at least 24 hours' notice before the system is ready for inspection. We coordinate with the site evaluator so the excavation follows the approved design.

Designing around Biddeford soils

The soil under a leach field decides almost everything about it. Lyman soils, common across the city's rural and coastal interior, are well drained but shallow, often with bedrock only 10 to 20 inches down, which usually means a mounded field built up with imported fill. Scantic and Naumburg soils have seasonal water tables within inches of the surface, and the Thatcher Brook study classes both as hydric. On those lots the evaluator's test pits set how high the field must sit, and the fill has to be placed and compacted to match.

Where a replacement system goes into an older lot with an existing house, access for the excavator, the tank location and the route of the building sewer are worked out before digging.

Near the shore and the river

The state's shoreland guidelines require septic systems in the shoreland zone to meet the Subsurface Wastewater Disposal Rules and limit clearing of woody vegetation to what the system actually needs. Near the Saco, the Saco River Corridor Commission's review also applies. After installation, disturbed ground is loamed and seeded promptly so it does not wash toward the water.
