Storage Tank Rule Guidance and Checklist Updates Underway

In 2020, the division worked with stakeholders to develop the updated Storage Tank Rule regulation and Policies DW-010, DW-012 and DW-015 that accompany the regulation updates. The Commission approved all proposed modifications in August 2020 and the regulation updates were effective on October 1, 2020. The Storage Tank Rule (Regulation 11, Section 28) protects public health and public water systems from potential contamination associated with unprotected storage tanks within the public water system’s drinking water distribution system. 

The Field Services Section is actively working on finalizing the Storage Tank Guidance and the periodic and comprehensive inspection checklists to reflect the 2020 Storage Tank Rule updates. The updates to the checklist will incorporate feedback inspectors have received from operators in the field during sanitary surveys. We hope that the updated checklist will be a clear, concise and useful tool for operators when conducting the periodic and comprehensive inspections that are key in ensuring safe drinking water.   

The goal for publishing the updated Storage Tank Rule guidance and checklists on our website is December 2024. If you have questions regarding implementation of the Storage Tank Rule, please email the Field Services Section at cdphe_wqcd_fss_questions@state.co.us. The department, operators and the supplier share the same goal – “Always Safe Drinking Water”.
