In the more than 30 years I have worked with onsite wastewater treatment systems, I’ve seen many things that don’t seem to make sense: drainfields with six feet of soil cover, tanks buried more than 10 feet to the top of the lid, a system pumped under a driveway through a garden hose.Each time I ask myself: Why take half measures? Why not design and install the best system for the money? I offer here some opinions about one type of drainfield design that doesn’t make sense to me, once we step back and evaluate what is being done against
Pump to Gravity: Does It Make Sense?
Once a pump has been added to the onsite system design, why not use it to take advantage of the benefits of pressure distribution?
