A rainwater tank only saves money when it is correctly sized, properly plumbed, and connected to the right end uses. We install poly and steel tanks integrated with your existing gutter system — including first-flush diverters, pumps, and connections to toilets and laundry where rebates apply.
Tank Installation Steps
- Sizing & siting
Roof catchment area, household usage, and block layout determine tank size and position.
- Base & tank set
Level concrete or crusher dust base prepared. Tank delivered and positioned.
- Gutter & plumbing connection
Downpipe diverted to tank with first-flush diverter. Pump and mains top-up configured.
- Internal connections
Licensed plumbing to toilets and laundry where required for rebate eligibility.
Rainwater Tank FAQs
What size tank do I need?
A 2,000–5,000 litre tank suits garden and outdoor use. Connected systems for toilet and laundry typically need 5,000–10,000 litres depending on household size and roof area.
Are government rebates available?
Melbourne water retailers have offered rebates for tanks plumbed to toilets or laundry. Availability changes — we advise on current programs at quote stage.
Can you connect to an existing tank?
Yes. We upgrade pumps, replace failed connections, and add internal plumbing to underused tanks.
