01. Winter Frost Protection

Sub-zero Highlands mornings can freeze and crack exposed pumps and pipework. Installers can fit insulated pump covers, lagged pipework, and submersible pump options.

02. RFS Fire-Fighting Water

Dedicated fire-fighting tanks (commonly 10,000L–20,000L depending on lot size) with 65mm metal Storz outlets and hardened truck access, as set out in NSW RFS guidelines. Check exact requirements with your certifier or NSW RFS.

03. Licensed Plumbing Hookup

In NSW, connecting a tank to your home’s plumbing, backflow prevention and stormwater overflow is plumbing work for a licensed plumber. Ask to see their licence before work starts.

Southern Highlands Rainwater Tank FAQs

How much does a 22,500L rainwater tank installed cost in the Southern Highlands?+

A turnkey package including a 22,500L Australian-made poly tank, compacted crusher-dust pad preparation, delivery, pressure pump, and basic downpipe connection typically ranges from $4,200 to $7,500 depending on trenching distance and pump specs.

Should I choose poly or steel for a bushfire-prone block?+

If the tank stores a dedicated fire-fighting water supply required for your property, NSW RFS Planning for Bush Fire Protection 2019 calls for above-ground tanks made of concrete or metal, so a steel tank (such as BlueScope Aquaplate) or an underground tank is the usual choice. Poly is still an option for household rainwater. Requirements depend on your BAL rating and development consent, so check with your certifier or NSW RFS.

Does BASIX require a rainwater tank?+

Not always. BASIX requires new homes to meet a water target, and a rainwater tank is the usual way to meet it, but your BASIX certificate is what sets the commitment. Check your certificate and with your certifier.

Do I need council approval for a rainwater tank?+

Many above-ground rainwater tanks can go in as exempt development in NSW if they meet the set conditions (such as size, height and setbacks). Larger tanks, underground tanks or properties with heritage or other constraints may need approval, so check with Wingecarribee Shire Council or your certifier before work starts.
