Land and Field Drains

After partial treatment by a septic tank, wastewater moves from the septic tank into perforated pipes, bedded on and surrounded in, gravel-filled trenches. To determine if your land will drain properly we can carry out a percolation test on your property to determine the suitability and size of your proposed drainfield.

From the pipeline nutrients and organic material are dispersed into the gravel where they are removed or neutralized as the liquid moves through into the soil. In a trench system, the effluent may flow into a series of drop boxes or manholes with another outlet to the next pipeline set at a higher level. As each set of trench lines reaches capacity, the drop boxes release liquids to the next set of pipes in the drainfield.
