As temperatures drop and winter weather approaches, water utility operators face unique challenges that can impact system reliability, infrastructure, and service to their communities.
From freezing temperatures and snow-covered equipment to increased demand and unexpected emergencies, preparing ahead of time is essential to keeping water and wastewater systems operating smoothly. A little preparation now can help prevent costly repairs, minimize disruptions, and ensure your community continues to receive safe, reliable service all winter long.
Use this winter prep checklist to help your utility stay ahead of the cold and ready for whatever the season brings.
Water System
Review emergency plans
Turn on well house furnace and check temperature sensors
Check emergency supply list, including repair clamps, main break parts, and equipment
Clear out valve boxes in known main break areas for easy access
Ensure all hydrants are properly drained following fall flushing
Wastewater System
Increase biomass to compensate for slower metabolic rates in the cold
Review treatment processes to ensure expected flow will be sufficient to prevent freezing.
Drain systems in preparation for prolonged freezing periods, specifically:
Thickening tank
Digester
Drying beds
Insulate samplers and lines
Clear walkways and catwalks to ensure safe snow and ice removal
Turn on heat tracing and check operation status along the entire length to ensure traced lines are protected from freezing and verify the tracing has not shorted in a portion of the line.
