Step 1: Know Your Water Usage

Understanding how you plan to use rainwater is the first step to determining the right tank size. Here are some common water usage estimates:

• Garden Watering:
• Approximately 20-30L per square meter of garden each week.
• Toilet Flushing:
• Around 5-10L per flush per person.
• Washing Clothes:
• Approximately 50-100L per load.
• Car Washing:
• About 100-150L per wash.

Add up your estimated weekly usage to get a clearer picture of how much water you’ll need to store.

Step 2: Consider Your Rainfall

Your local rainfall will significantly impact how much water you can collect and store. Use this simple formula to estimate your potential collection:

Rainfall (mm) x Roof Area (m²) x 0.9 = Total Litres Collected

For example:

• If your area gets 50mm of rain and your roof is 100m², you could collect:
• 50 x 100 x 0.9 = 4,500L of rainwater per rainfall event!

Check your local rainfall patterns to calculate your potential water supply.

Step 3: Match Your Tank Size to Your Needs

Once you’ve estimated your water usage and rainfall collection potential, you can choose the right tank size. Here’s a quick guide:

• Small Tanks (1,000L - 5,000L):
• Ideal for gardens and light outdoor use.
• Medium Tanks (5,000L - 14,000L):
• Perfect for household tasks like toilet flushing, laundry, and light washing.
• Large Tanks (10,000L - 27,000L+):
• Great for whole-property use, irrigation, and large families.
