View the PDf iconWater System Plan Review Requirements for more details. Resources related to plan review requirements are listed below:

Plan Review Exemption

Plan review exemption for water main extensions may be available for some community water systems.

Instruction Packets and Fee Table

The PDf iconWater System Plan Review Requirements is a document generic to all plan reviews. To provide more focused assistance, especially for submitters having little or no experience with the plan review process, Drinking Water Services is developing "information packages." These packages are provided below:

*Number of connections is based on water system size not on how many connections are served by the project
** Examples include: arsenic or nitrate removal, disinfectant residual maintenance, coagulant injection.
*** Projects submitted jointly will be issued joint conditional and final approvals.
