The purpose of this program is to ensure proper treatment and disposal of waste water to protect our drinking water and the environment. At GCHD we permit, inspect and investigate complaints associated with on-site sewage systems. Other activities include site reviews, plan preparation, and review of proposed land developments.
Anyone who installs, alters or repairs an on-site sewage system is required to first obtain a permit from GCHD. Installation of a system requires site and soil evaluations to ensure the proper system is installed to prevent environmental contamination.
We also maintain records of existing on-site sewage systems for your convenience. To assist in this process, please have your address, your parcel number available, the year the system was installed, and the name on the original permit.
We maintain a list of designers, installer, and pumpers in the local area. The following forms are available for download:

Residential Home Owners putting in a on-site septic system
The Grant County Health District is responsible for overseeing the design and installation of on-site septic systems with wastewater flows under 3,500 gallons per day. There are many variables in designing septic systems which is why the Washington State Department of Licensing now licenses Septic Designers like they do Professional Engineers. For this reason, the Grant County Health District cannot assist property owners in designing septic systems.
This binder provides information if a homeowner wants to design their own gravity septic system. The first step is having a Site Registration performed by a licensed Septic Designer or Professional Engineer. If the Site Registration shows the lot conditions are acceptable for a conventional gravity septic system, then the resident home owner may design their own septic system. Being that the Site Registration must be done by a licensed Septic Designer or Engineer, it is almost always more efficient to have them design the septic system as well. Included in this binder is a list of State licensed Septic System Designers that work within Grant County
