Water Tank Installation Bellbowrie
Rainwater tanks are more common in Bellbowrie and the surrounding western Brisbane suburbs than almost anywhere else in the city — many acreage properties already depend on them as the primary or sole water source. Whether you need a new system, an upgrade, a pump replacement, or licensed plumbing connections to toilets and laundry, we handle the full job.
Rainwater Tank Installation & Servicing — Bellbowrie, Moggill, Pullenvale & Western Brisbane
Western Brisbane receives around 1,100 to 1,200mm of rainfall annually, with a large portion arriving in intense summer storms that can overwhelm drainage if the system isn't properly sized. On acreage blocks in Bellbowrie, Pullenvale, Moggill, and Anstead, large roof catchment areas can yield tens of thousands of litres per year — enough to supply all non-drinking household uses and significantly reduce mains water bills. Many properties in these suburbs already have a tank and pump system; we service, upgrade, and repair existing systems as well as design and install new ones.
For properties switching from mains-only to tank-supplemented supply, or upgrading an ageing tank and pump, the key decisions are tank size and placement, pump selection and pressure settings, first-flush diverter sizing, and how many fixtures will be connected. We assess the roof catchment area, the available installation space — which on acreage blocks is rarely a problem — and the intended uses, then provide a fixed-price quote covering the complete licensed installation.
All installation work is certified and compliant with Queensland plumbing regulations and council requirements. We advise on council rebates where applicable.

What Can You Use Rainwater For?
Rainwater can supply most of your household's non-drinking water needs.
Toilet Flushing
Typically 20–25% of household water use. Requires a licensed connection with appropriate backflow protection.
Laundry
Washing machines use approximately 10–15% of household water. Rainwater connection requires a licensed plumber.
Garden & Irrigation
Outdoor watering, irrigation systems and garden hoses. Connect directly or via pump — no licensed plumber required for outdoor-only use.
Outdoor Taps & Car Wash
Outdoor tap connections for car washing, pathway and driveway cleaning, filling pools and general outdoor use.
Indoor connections require a licensed plumber
Rainwater used for toilets and laundry must be plumbed in correctly with proper cross-connection controls to prevent rainwater from mixing with or contaminating the town water supply. This work requires a licensed plumber and a compliance certificate. All our indoor connections are certified to Queensland standards.
How We Install Your Rainwater Tank
A complete installation handled by licensed plumbers — from first assessment to compliance certificate.
Site Assessment & Sizing
We assess your roof catchment area, available installation space, and what you want to use the rainwater for. From this we recommend the right tank size and type — whether a standard poly tank, slimline, underdeck, or bladder tank — to match your property and goals.
Stable Base Preparation
A full tank can weigh several tonnes. We confirm the base is appropriate — concrete slab, compacted gravel pad or a purpose-built stand — and position the tank in the right location close to the main downpipe and supply area.
Inlet, Outlet & First-Flush Diverter
We connect the downpipe to the tank inlet and install a first-flush diverter — a device that discards the first dirty water off the roof before it enters the tank, keeping your water clean. Tank overflow is also connected to drain safely away from the property.
Pump & Filtration Setup
Most indoor connections require a pressure pump to maintain adequate flow. We select and install an appropriate pump and any filtration required, and connect the supply line to your plumbing system. A backflow prevention device is installed where the system connects to town water (for backup supply).
Test, Certify & Customer Handover
We test the full system before we leave — inlet, pump, all connections and overflow. We issue a compliance certificate for the plumbing work, and walk you through how the system operates, how to maintain it and what to check periodically.
