If you use rainwater for potable or greywater applications, conduct a basic water test for:
- pH level
- Turbidity (cloudiness)
- Microbial contamination (for potable use)
Address any issues promptly to maintain safety.
Autumn: Leaf Management and Pre-Winter Preparation
Install and Maintain Leaf Guards
Falling leaves are a major source of clogs and tank contamination. To manage:
- Install leaf guards or mesh screens over gutters and tank inlets
- Clear leaves from guards weekly during peak drop season
- Inspect downspout strainers and clear as necessary
Flush First Flush Diverters Regularly
Autumn debris can quickly fill diverters. Open and flush these devices more frequently to prevent blockages.
Inspect Tank Lids and Overflow Paths
As winter approaches, check that lids are secure and that overflow pipes are clear and directed away from foundations to prevent water damage during storms.
Clean and Store Unused Components
If you use portable or seasonal components (such as extra barrels or hoses), clean and store them in a dry area before freezing temperatures arrive.
Assess Structural Integrity
Before winter, inspect all above-ground tanks and stands for signs of wear, cracks, or instability caused by settling or shifting soils.
Winter: Freeze Protection and System Safeguarding
Drain and Bypass Non-Winterized Systems
If your system is not designed for freezing temperatures:
- Drain all water from tanks, pipes, and pumps to prevent freeze damage
- Bypass or disconnect collection pipes from tanks
- Store pumps and sensitive equipment indoors
Insulate Exposed Components
For systems that operate year-round in cold climates:
- Wrap exposed pipes with foam insulation
- Use tank insulation blankets or build insulated enclosures
- Install heating elements or tank de-icers if necessary
Monitor for Ice Blockages
Inspect gutters and downspouts for ice buildup after storms. Use roof rakes or safe de-icing methods to clear blockages.
Check for Animal Intrusion
Rodents and small animals may seek shelter in tanks or pipes. Ensure all access points are sealed, and inspect for evidence of intrusion.
Review Emergency Overflow
Winter thaws can cause sudden influxes of water. Ensure overflow outlets are clear and direct water safely away from structures.
