Marin Water submitted application for COVID-19 relief funds
To help provide relief for hardships created by the COVID-19 pandemic, the California State Water Resources Control Board established the California Extended Water and Wastewater Arrearage Payment Program (Extended Arrearage Program). This program uses federal funding from the American Rescue Plan Act to assist with Californian's water bill debts accrued during the pandemic. Marin Water has applied for additional funding from the Extended Arrearage Program to provide relief to customers for unpaid water bills incurred between Jun. 16, 2021 and Dec. 31, 2022.
