Rainwater Tanks & Pumps
Rainwater Tank Installations Across Sydney & The Blue Mountains

System design
Tailored system design for every property
No two properties collect or use water the same way. Before we quote anything, we assess the site and design the system around how you'll actually use it.
Roof catchment size
How much roof area actually feeds the tank determines how much water you'll realistically collect each year.
Water usage requirements
Garden only, or toilets and laundry too? Your usage sets the tank size and the pump you need behind it.
Available installation space
Slimline, round or under-deck — we work to the space you have, including access for future servicing.
Pump and plumbing compatibility
The tank, pump and existing household plumbing have to work as one system, not three separate parts.
Drainage and overflow requirements
Overflow has to go somewhere legal and sensible — usually stormwater, never against your foundations.

Get it right first time
Why proper installation matters
A poorly installed rainwater system causes problems that cost far more than doing it properly at the start.
Low water pressure
An undersized or badly matched pump leaves you with a trickle at the tap and a system you stop using.
Pump burnout
Poor setup makes the pump cycle constantly, and constant cycling kills pumps early.
Tank contamination
No first-flush diversion or unsealed inlets let debris, insects and organic matter straight into your stored water.
Constant maintenance issues
Badly installed systems need attention every few months instead of a simple annual check.
Water loss through leaks and overflow
Bad seals and uncontrolled overflow waste the water you installed the tank to save.
