Key Takeaways

•You can't challenge a water supplier's plan or decision just anytime—there are strict time limits.
•If the supplier didn't make a required plan, you have 18 months to complain.
•If the plan or an action doesn't follow the rules, you only have 90 days to challenge it after it's filed or done.

Example

A city's water supplier makes a new plan for handling water shortages, but a group of residents thinks the plan doesn't follow the rules.
