Autumn Tank Care: Keeping Your Rural Water Supply Safe and Reliable

As the leaves begin to fall and the days cool down, autumn is the perfect time for rural homeowners to give their water tanks a bit of attention. For many New Zealand households, collected rainwater isn’t just a convenience—it’s the primary source of drinking water. At Water MD, we know how important it is to keep that supply clean, safe, and running smoothly.

Here are a few simple but important actions you can take this autumn to protect your water quality and avoid costly repairs down the line:


1. Clear Gutters and Downpipes
Falling leaves and debris can quickly clog your gutters and downpipes, reducing water flow and introducing organic material into your tank. Regularly clearing these out helps ensure clean water collection and prevents blockages.
2. Check Your First Flush Diverter
If you have a first flush system installed, autumn is a good time to make sure it’s working properly. This device diverts the initial, dirtier runoff away from your tank—especially important when roofs are covered in leaf litter.
3. Inspect Tank Lids and Screens
Make sure your tank lid is secure and that inlet screens are intact. This prevents pests, insects, and debris from entering your water supply.
4. Look for Sediment Build-Up
Over time, sediment can accumulate at the bottom of your tank, affecting water quality and potentially damaging pumps. If it’s been a while since your last clean, autumn is a great time to book a professional inspection or clean.
5. Test Your Water Quality
Seasonal changes can impact water quality. Consider testing your water or installing appropriate filtration to ensure it remains safe for drinking.
6. Prepare for Winter Demand
With increased rainfall and potential storms ahead, now is the time to ensure your system is in good working order. Check pumps, pipes, and overflow systems so you’re ready for heavier use.
