OWTS (On-Site Wastewater Treatment System Permits)
What the System Is
A septic system is a method of disposing and treating household wastewater in areas where public sewers are not available.
The standard type of septic system involves a septic tank, to hold wastewater from toilets and drainpipes until solids settle out in the tank, and a system of pipes that distribute the remaining liquid waste underground over a large area --the leach field--where the wastewater "percolates" through the soil, which helps to clean the water.
The goal is to make sure that this filtration though the soil is sufficient to clean the wastewater before it reaches drinking water well sources or surface waters.
Gunnison County refers to these systems as On-Site Wastewater Treatment Systems (OWTS) Additional information is available from:
"Principles and Design of Onsite Waste Disposal with Septic Systems" is a downloadable software program available from the U. S. Environmental Protection Agency that teaches the basics of on-site treatment using diagrams and animations of septic tanks, drain fields, mounds, water conservation. Covers principles of treatment, design, and siting, as well as soil basics and water conservation.
