Abstract
Wastewater system design, installation, maintenance and use are described and provided. In embodiments, design, installation, and maintenance of pressure gradients in a septic system serve to transport treatment tank gases, or other gases, downstream, towards or into a leach field, bio-filter, drain field, or other environment. Such transport may promote the displacement of gases or the remediation of gases.
Claims21
A wastewater treatment system comprising:
- a subsurface wastewater treatment tank in fluid communication with a plumbing vent, the treatment tank substantially protected from ground water entry and rain water entry;
- and
- a first pressure gradient system in fluid communication with the treatment tank, the pressure gradient system acting on head space in the treatment tank to create a pressure gradient serving to transport head space gases towards a leaching field downstream of the treatment tank.
