Certificate of Water Availability: For single-family or two-party water system For public water system |
In order to obtain a septic system permit or building permit, applicants must prove they have source of water. This is accomplished by supplying a "Certificate of Water Availability Form." If the source of water is a well (or is a well serving a single-family, two family or Group B water system, the applicant is required to submit a well log report that describes the well's capacity and construction. This is to ensure that the well meets minimum construction standards and is capable of delivering the necessary volume of water. See column to the right. If the source of water is surface water, the applicant is required to submit a copy of the notice regarding use of surface water as recorded with the Thurston County Auditor's Office. See column to the right. |

Well Site Supplemental Application - SA 020 |
To get approval to build a new well or connect to an existing
well. For proposed new wells, SA 020 asks about site conditions
and possible nearby contaminants. Once the well site has
received approval, a single-family well can be drilled and
tested by a licensed well driller; however, a two-party or Group
B water system must submit a Water System Design application
before drilling (SA 019 - below). For existing wells, SA 020 asks about site conditions, well components and water-quality information. If the Building Development Center finds the existing well to be adequate, the applicant may connect to it. |
Well Site Application Guide Also see "Wet Season Study" above. |

Protective and Restrictive Covenants - to protect drinking water from contamination from land uses | ||
Forms | Description | Related Info. |
The following forms are all on legal-sized paper: Covenant Form - Public Water Source Covenant Form - Non-Public Water Source Restrictive Form -- Public Water Source Restrictive Form -- Non-Public Water Source |
A covenant is a recorded agreement that gives property owners
the legal ability to control activities within a certain radius
of their well that could affect their water quality. This
"sanitary control area" is 100 feet for wells and 200 feet for
springs. Use the regular covenant form if you, or your water
supplier, own all or part of the land in the sanitary control zone;
if a neighbor owns some of the land in the zone, you'll also
need to get a restrictive covenant form from the landowner as
well. Non-Public = single family Public = 2-party, Group B, Group A water systems |
