How Do You Repair a Leach Field?

To repair a leach field, restore the septic tank to reduce the load on it, decrease the amount of waste put in the tank, avoid excessive wetting of the soil close to the field, and make a separate drain field for wash water. In addition, drain water from the septic tank, and remove any debris from the pipelines of the field regularly.

When restoring the septic tank, conserve water to the extent possible, and fix leakages in the toilet or faucets at the earliest. Additionally, increase the leach field area so its capacity matches the septic system's use. This is particularly helpful if the soil in the area exhibits poor drainage capacity.

Compost vegetable and food waste instead of putting it in the garbage disposal, and avoid flushing paper towels, tissues and pet litter. Use biodegradable tissues if possible. These measures reduce the waste load on the septic tank.

To avoid excessive wetting of the soil close to the leach field, locate it at a place with a low groundwater level. In addition, avoid irrigating the area, and don't create a vegetable patch on the drain field.

Drain the water from the septic tank once every three to five years using a pump to prevent the tank's baffles from getting blocked. Have a professional plumber remove debris such as tree roots from the pipelines of the leach field. Maintain a distance of over 10 feet between big trees and the drain field.
