How to Build a Water System Compliance Calendar

August 2026 · Orevant Compliance Intelligence

For most small water system operators, compliance tracking is an afterthought. A spreadsheet maintained by whoever has time, a folder of past reports, or institutional memory held by one person. That system works until someone leaves, the spreadsheet gets out of date, or a regulatory change shifts a deadline nobody was watching. The result is a violation that triggers public notification, corrective action, and a permanent record in the EPA SDWIS database.

What a Compliance Calendar Must Cover

Monitoring Schedules

Every public water system has a monitoring schedule set by its primacy state agency covering microbials, disinfection byproducts, inorganic contaminants, and radionuclides. Missing a monitoring window is a monitoring and reporting violation even if your water quality is perfect.

Reporting Deadlines

Monitoring results must be submitted to the state agency on specific schedules. Reporting deadlines are separate from sampling deadlines. A system can collect samples on time and still incur a violation by submitting results late.

Consumer Confidence Report

Community water systems must deliver a CCR to every customer by July 1 each year. Filing late is a direct violation. Failing to deliver to customers is a separate violation from filing with the state.

PFAS Monitoring Obligations

Under the 2024 PFAS MCL rule, systems must complete initial monitoring by April 2027. These obligations layer on top of existing monitoring schedules and need their own tracking.

Lead Service Line Inventory Updates

Annual updates to the lead service line inventory are required under the LCRR. Replacement progress must be documented and reported.

Sanitary Survey Corrective Actions

Sanitary surveys generate deficiencies that carry corrective action deadlines set by the state. Significant deficiencies must be resolved within defined timelines typically 120 days.

Why Manual Tracking Fails

Spreadsheet-based compliance tracking captures what you knew at the time you built it. Regulations change. Deadlines shift. New requirements layer on top of old ones. A spreadsheet built in 2022 does not reflect the LCRR inventory requirement added in 2024 or the PFAS monitoring obligations effective in 2027. Institutional memory is even more fragile.

How Orevant Automates Your Compliance Calendar

Orevant builds your compliance calendar from your system actual data. Every requirement is sourced to the actual regulation. Deadlines are calculated automatically and updated when rules change. The monitoring subscription at $87 per month sends escalating reminders at 90, 60, 30, 14, 7, and 3 days before each deadline. When a regulatory update affects your system specifically you get notified.
