When people build structures outside the City limits of Cities, there are not service linesSeptic Tanks that carry sewage to municipal treatment plants. On-site sewage facilities (OSSF) are designed to provide a safe method of disposal for sewage without harm to people or the environment. Since the late 1970’s the Amarillo Bi City-County Health District has permitted and inspected septic systems within Potter and Randall Counties.


The Environmental Health Department is the Permitting Authority for the AuthorizedSeptic Drainfield Agents (Potter and Randall Counties). This department employs Designated Representatives licensed with the Texas Commission on Environmental Quality. This authorization is granted to Environmental Health by County Order in both Potter and Randall Counties. Title 30 of the Texas Administrative Code Chapter 285 On-Site Sewage Facilities provides rules that detail the minimum standards for permitting, installing and operating OSSF within Texas.

Each year Environmental Health permits over 500 septic systems within Potter and Randall Counties. Any owner of a facility or home that does not produce more than 5000 gallons of domestic sewage per day may apply for a permit to construct an OSSF unless the property is located within a municipality then permission from the Director of Utilities must be obtained prior to application. Owners of single-family dwellings may install their own septic system. Certified Installers that hold valid licenses issued by the Texas Commission on Environmental Quality must install all other OSSF.
