Protecting the drain field on a Manchester property

The drain field is the part of a Manchester septic system that costs the most to replace. Keep it clear of parked cars, sheds, patios and deep-rooted trees. Route roof drains and sump pumps away from it so the soil is not already soaked when wastewater arrives. Grass is the best cover, because it helps the soil breathe and take up water.

When to call a septic company

Call when drains slow down throughout the house, pipes gurgle, sewage smells appear indoors or in the yard, or the ground over the tank or drain field turns soggy or unusually green. A backup in the lowest drain in the house needs attention the same day. If you are buying or selling a home in Manchester, schedule an inspection early so there is time to act on what it finds.

What to ask before you hire

Useful questions include: Are you licensed for septic work where I live? Will you inspect the baffles and filter when you pump? What would you recommend and why? Is a permit needed? Companies that serve Manchester regularly should know the local rules and the systems common in the area.

New construction and septic in Manchester

Building on a lot without sewer near Manchester starts with a soil evaluation and a permit from Hillsborough County. The soil test decides what kind of system the lot can support and how large the drain field must be. Some lots need a mound or another engineered system. Get this done before finalizing house plans.

Local conditions in Manchester

Among the mapped soils within about two miles of central Manchester, the USDA soil survey rates 99% as very limited for septic absorption fields, 0% as somewhat limited and 1% as not limited. The most common drainage class is well drained. Soils like these often call for careful system design, such as a larger drain field, a mound or another engineered system, and a site evaluation before any new installation or replacement.

Manchester averages about 46 inches of precipitation a year, and October is usually the wettest month. Average temperatures stay below freezing for about 3 months a year, with January averaging 23°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
