Call (207) 747-1472Sewer Line Replacement on Scarborough Properties
Scarborough's building sewers are younger than those in Portland, but they still fail. In the clay soils that cover much of the inland town, pipe can settle into bellies or shift at the joints, and older lines from mid-century neighborhoods may still be clay tile or cast iron. On septic properties, the line from the house to the tank is often the first thing to clog or crack. A camera inspection pinpoints the problem before any digging, and it measures how deep the line runs and where it turns. Replacement uses PVC or HDPE, bedded so it holds grade in soft ground, and connections to the public main are coordinated with the Scarborough Sanitary District, which also owns and maintains most of the town's public sewer.
Warning Signs
Signs Scarborough Properties Need Sewer Line Replacement
Frequent Drain Clogs & Backups — If multiple drains are backing up, your sewer line may be failing.
Soggy Yard or Sewage Smells — Leaks or breaks in the sewer line can cause standing water and foul odors.
Slow Draining Fixtures — If sinks, showers, and toilets drain slowly despite attempts to clear them, your sewer line may be blocked or damaged.
Cracked or Shifting Pipes — Tree roots, soil movement, and aging can cause sewer pipes to crack or collapse.
Old or Deteriorating Sewer Line — Many older homes still have clay, cast iron, or Orangeburg pipes, which degrade over time and require replacement.

Scarborough Conditions That Shape Sewer Line Replacement
Public sewer and private septic in Scarborough
Public sewer in Scarborough belongs to the Scarborough Sanitary District, a separate body created in 1969 and governed by an elected board. The town's 2021 comprehensive plan records about 68 miles of district gravity sewer, 23.5 miles of force main, 23 pump stations and a treatment plant upgraded to 2.5 million gallons a day. It also counts roughly 6 miles of private gravity sewer, 6.6 miles of private force main and 34 private or association pump stations tied in. The district accepts septage from septic owners, and much of western Scarborough remains unsewered.
Scarborough soils and what they mean for a leach field
Scarborough's ground changes sharply from east to west. Along the coast, Pine Point and the beaches sit on sand, and the marsh behind them is saturated tidal peat and silt. Inland, much of the lowland carries glacial-marine clay that drains slowly, and the town's own comprehensive plan flags clay soil locations as a key planning constraint. West of the Turnpike, mapped sand and gravel aquifers feed residents' wells. For a septic design, that means a coastal lot may have fast-draining sand over a high water table, while an inland lot may have tight clay that barely accepts water at all.
Scarborough housing age and what it means underground
Scarborough's population roughly doubled between 1980 and 2020, to about 22,100, making it the largest Maine municipality still governed as a town. The 2024 Census estimate counts about 11,100 housing units with a median year built of 1988, about two decades newer than South Portland's. Many septic systems in the western subdivisions date from the 1980s and 1990s building boom and are now reaching the age when fields start to fail. Older cottages at Pine Point and Higgins Beach sit on small lots with tight setbacks.
