Water System Plans in Review Process

Some public water systems are required to submit planning documents to the Department of Health, Office of Drinking Water (ODW) for review and approval. ODW has prepared a list of active Water System Plans (WSPs).

• View list of active Water System Plans (WSPs) (PDF, updated 03/12)

The planning process starts with a preplan meeting between the water system and ODW staff. Then the water system  prepares and submits the document. After receiving the submittal, ODW has 90 days to review and respond to the water system. There may be several rounds of comment and response before the final version is approved.

The tables represent a snapshot of work in progress. We will update it periodically. If you have questions about this information, contact your regional planner.
