Spring

• Inspect and Clean Gutters: Remove leaves, twigs, and other debris from gutters and downpipes to prevent blockages. Clogged gutters can lead to water overflow and contamination.
• Check Roof Condition: Examine the roof for signs of damage, such as cracked or missing shingles, which could introduce contaminants into your water supply.
• Trim Overhanging Branches: Cut back any tree branches that hang over the roof to reduce debris accumulation and minimize animal access.

Summer

• Monitor Water Usage: During drier months, keep an eye on water levels and usage to ensure you have sufficient supply.
• Inspect Tank for Leaks: Examine the tank and associated pipework for any signs of leaks or damage, addressing issues promptly to prevent water loss.
• Clean Tank Inlet and Screens: Remove any debris from inlet screens and ensure that insect-proof screens are intact to prevent contamination. 

Autumn

• Deep Clean the Tank: As leaves fall, it’s an ideal time to schedule a thorough cleaning of your water tank to remove sediment buildup. This task is best performed by professional tank-cleaning contractors to ensure safety and effectiveness.
• Install or Check First Flush Diverters: Ensure that first flush diverters are functioning correctly to prevent the initial, most contaminated rainwater from entering the tank.
• Inspect Overflow Outlets: Confirm that overflow outlets are clear and direct excess water away from the tank’s foundation to prevent erosion.

Winter

• Check for Frost Protection: Ensure that pipes and pumps are insulated or otherwise protected against freezing temperatures, which can cause damage.
• Review Tank Foundation: Inspect the tank’s base for signs of erosion or undermining, especially after heavy rains, and reinforce as necessary.
• Test Water Quality: Consider having your water tested for contaminants to ensure it remains safe for consumption.

General Maintenance Tips

• Regular Roof Cleaning: Periodically wash down roof surfaces with an environmentally friendly detergent, ensuring that the pipe leading to the tank is disconnected during cleaning to prevent contamination.
• Maintain Surrounding Area: Keep the area around the tank clear of vegetation and debris to deter pests and allow easy access for maintenance.
• Document Maintenance Activities: Keep a log of all inspections, cleanings, and repairs to track the history of your rainwater harvesting system.

By keeping to this seasonal maintenance schedule, you can help ensure that your roof-collected rainwater remains a safe and sustainable resource for your household in our kiwi environment.
