Rainwater Tanks & Stormwater Solutions in Adelaide
Adelaide is famous for its unpredictable climate—long, dry summers followed by sudden heavy winter downpours. Without a proper rainwater and stormwater system, you risk higher water bills, flooding, and foundation damage. That’s why South Australian councils now require rainwater tanks for new builds and major extensions.
At Deadshort Services, we’ve been helping Adelaide homeowners and businesses manage water for over 35 years. From rainwater tank installations to stormwater drainage upgrades, our licensed plumbers deliver solutions that are reliable, compliant, and built to last. And because we’re a multi-trade team—with plumbers, roofers, electricians, and builders—we handle the entire job in-house.

Rain Water Tank Connection Guide
How Rainwater Tanks Work and Connect with Your Property
A complete system involves more than just the tank itself. Here’s the process in simple steps:
Roof & Gutters – Rainwater is collected from your roof.
Downpipes & Leaf Diverters – Water is filtered to remove leaves and debris.
First Flush Devices – Divert the initial dirty water away from the tank.
Tank Storage – Clean water is stored in your rainwater tank.
Pump & Filters – Water is pumped into your household plumbing, often with added sediment filters.
Connection to Your Home – Water is supplied to toilets, laundries, garden taps, or even the hot water system.
- Connection through water filtration system – water is filtered through a full h house system taking out any harmful materials, click here for more information.
Because rainwater and stormwater systems cross over between trades, Deadshort Services manages the entire process seamlessly—from guttering to pump wiring.
Council Rules & Compliance in South Australia
South Australian building regulations here at SA Gov set out clear requirements for rainwater tanks:
Minimum Size: New homes and extensions over 50 m² must include at least a 1,000 L plumbed rainwater tank.
Plumbing Connection: Tanks must be connected to toilets, water heaters, or cold-water laundry outlets.
Overflow Protection: Tanks must include an overflow device to prevent flooding.
Mosquito Screens: All inlets and overflows must be screened.
Approval Triggers: Tanks larger than 10 m² in footprint or taller than 4 m usually require development approval via PlanSA.
Deadshort Services takes care of all compliance requirements for you. We know the council rules inside out, so your tank will always meet South Australian standards.
Rain Water Tank Size Guide
Honest Pricing — No Gimmicks
Some companies advertise “rainwater tanks from $99.” We don’t make silly claims like that. Every property is different, and costs depend on:
Tank size and material
Base type (slab vs. compacted dust)
Pump size and power
Plumbing distance and complexity
Council or detention system requirements
At Deadshort Services, we inspect your site and provide a clear, upfront quote. No inflated “worst-case” numbers. No hidden extras. Just honest pricing backed by decades of experience.
How much does it cost to install a rainwater tank?
Small, simple systems are more affordable, while large installations with pumps and detention requirements cost more. Either way, you’ll know the true cost before we begin.
Maintenance & Longevity
Rainwater tanks are relatively low-maintenance, but they still need care:
Clean gutters and leaf diverters
Check mosquito screens and overflows
Service pumps and replace filters
Inspect for cracks, leaks, or rust
Flush first flush devices
With regular upkeep, poly tanks can last 15–20 years, and steel tanks often 25 years or more. Deadshort Services offers programmed maintenance plans to keep your system in peak condition year-round.
Bushfire Zone Considerations
For Adelaide Hills and other bushfire-prone areas, special requirements apply:
Non-Combustible Materials: Steel tanks are recommended over poly.
Access for Emergency Services: Tanks must be placed where fire trucks can access them quickly.
Dedicated Fire Outlets: Fittings compatible with firefighting equipment may be required.
Our team understands these additional rules and can design a compliant system that supports both your household and bushfire safety needs.
