What's New?
 

  • New Online Start-Up Procedures for Seasonal Public Water Systems
    The DWP is pleased to introduce a new submission option for the State-approved seasonal start-up procedure (SSUP). Seasonal water systems, using either groundwater or surface water, can now submit their SSUP information completely online. Certify completion of your SSUP easily to the DWP saving paper, time, and money. The paper SSUP forms will still be accepted, but PWSs should be sure to use the 2025 revision from our website. Remember: Seasonal water systems must perform a State-approved startup procedure and provide certification to the DWP that they have met that requirement. Certification must be completed and sent to the DWP before serving water to the public. Click here to learn more or access the new online SSUP forms.
