Kittitas County Approves Revisions to Water Code

Kittitas County, WA - 09/25/2017 - On September 21, 2017 the Kittitas County Board of Health (BOH) and the Board of County Commissioners (BOCC) approved revisions to Kittitas County Code Chapter 13.25 (Cistern Water System Requirements), Chapter 13.35 (Adequate Water Supply Determination for Building Permits), Chapter 13.40 (Mitigation and Metering), as well as the 2017 Kittitas County Public Health Department fee schedule and policy.

“These revisions are meant to make it easier for homeowners to access water in areas where water isn’t currently available through a well,” states Kittitas County Commissioner Paul Jewell. 
The water code revisions primarily increase access to an alternative potable water resource (cisterns) for homeowners who are located in “red zones” or areas where water mitigation is not available.  The changes also included some code and policy clarifications not associated with the cistern changes.  The most significant changes include the following:

  • Changing the licensing and inspection requirements for commercial potable water haulers from annually to every two years, and the reporting requirements from monthly to quarterly
  • Requiring a mitigation certificate for withdrawal of domestic use water from a Group A community water system within the green zone of the source of mitigation
  • Changing the cistern user reporting and water testing requirements from quarterly to annually. 
  • Removing the Interim Measure code language for Adequate Water Supply Determinations
  • Requiring that cistern users receive an Adequate Water Supply Determination (Form C) approval prior to receiving a building permit
  • Allowing cistern users to mitigate for water usage through the Kittitas County Water Bank and adding a new package C  of 150 gallons per day (annual average) specifically for cistern users
  • Allowing recipients of mitigation certificates from the Kittitas County Water Bank two years (instead of one) to apply for a building permit
  • Revisions to the fee structure for the cistern water system program
