Water Program >> Two-Connection Residential Water Systems
The Snohomish Health District reviews and approves new two-connection drinking water supplies. Examples of two-connection
water supplies include:
two single family residences on separate properties sharing one well,
a single family residence and an accessory apartment on the same property sharing one well,
a duplex unit on one property sharing one well. Each side of a duplex is considered as one connection
For SHD approval of a two-connection well, the following requirements must be met:
Approved well site
A completed “Application for an Individual Water Supply Site Inspection” must be submitted along with the applicable fee.
The SHD will then conduct a site review to verify that the potential well site is in compliance with
WAC 173-160.
If the two residences to be served are not located on the same property, then a separate well site application for each property must
be submitted.
SHD Approval of “Request for Review: Individual Water Supply”
The following information must be submitted:
Signed Declaration of Applicant (available from SHD Water and Wastewater Section)
Satisfactory results of inorganic chemical analysis for the
