Septic Maintenance in Hattiesburg and the Pine Belt
In a place that gets as much rain as the Pine Belt, septic maintenance is mostly about water: how much goes in, and how wet the ground already is.
Control the water you add
- Fix running toilets and dripping taps. They can add a lot of water per day.
- Spread laundry over the week, especially in wet spells.
- Direct roof gutters, driveway runoff and sump pumps away from the field.
- Consider high-efficiency fixtures when replacing old ones.
Look after the tank
Have it pumped about every three to five years by an MSDH-certified pumper, avoiding the wettest weeks if your ground is saturated. Use an effluent filter if your system has one and have it cleaned at pump-outs.
Treatment units and mounds
Advanced treatment units must be maintained to the certified manufacturer's requirements. That means keeping the power on, servicing them on schedule and dealing with alarms. For mounds, maintain grass cover, keep vehicles off, and check the base for seepage after heavy rain.
Trees and the field
Keep pines and other trees well away from the system, as roots are a leading cause of clogged lines in the area. Plant only shallow-rooted grass over the field.
Storm season prep
Before hurricane season, which runs June to November, know where your tank, lids and any treatment unit breaker are. If a storm floods the area, cut water use and have the system checked before going back to normal.
