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.
