Limiting water use helps reduce strain on the wastewater system during and after a storm. Heavy rainfall can increase flows into the sewer system, and reducing nonessential water use, such as doing laundry, taking long showers, or running the dishwasher, helps wastewater treatment facilities and crews manage the increased demand while responding to storm-related impacts.
Before the storm: Equipment and water storage tanks are prepared for the storm by staff. Conserving water helps ensure there is enough drinking water available if power outages or damage disrupt pumping or treatment.
During the storm: Heavy rain and flooding can overwhelm wastewater systems. Using less water (showers, laundry, dishwashers, etc.) reduces the amount of wastewater entering the sewer system, lowering the risk of sewer backups and untreated wastewater overflows.
After the storm: Even if the rain has stopped, treatment plants, pump stations, and distribution systems may still be operating on backup power or dealing with flooding, debris, or repairs. Conserving water gives crews time to restore normal operations and helps maintain water pressure.
