Planning a tank for a Newmarket home? Here is what the plumbing involves, what the council wants first, and the upkeep that keeps the water clean. The pipework side sits alongside our water pipe repairs work, because a tank line is just one more run of pipe to keep sound.

Parts of a Tank Plumbing System
Rain runs off the roof, passes a first flush diverter and enters the tank through a screened inlet. A plumbed outlet then carries the stored water to the cisterns, the washer's cold feed and the garden. A licensed plumber makes that connection, because the tank ties into the home's water supply. The parts that matter:
First flush diverter
catches the first, dirty runoff after a dry spell, so leaves, dust and bird mess stay out of the stored water.
Screens on every opening
each vent and opening, the overflow pipe included, needs a screen or flap valve that blocks mosquitoes. Brisbane specs want gaps below one millimetre, using stainless steel or aluminium mesh that lifts off for cleaning.
The outlet line
feeds whichever fixtures you choose, sized to suit the distance it has to run.
Overflow to stormwater
stormwater connections are a council requirement, so the overflow must tie into the site drainage rather than spill at the slab edge.

Safe Uses of Tank Water Around the House
Rain off your roof can flush toilets, fill the washing machine's cold inlet and water the garden without further treatment, because the disease risk from these jobs is low. Drinking, personal hygiene and food preparation stay on town water, which is the safer and more dependable supply, unless no town water reaches the property. Two rules of thumb:
Low-risk jobs
cisterns, the washer's cold tap and the garden can all run on roof-harvested rainwater.
High-care jobs
anything you drink, cook with or wash in stays on town supply where it is available.

Where a Tank Can Go and Who Approves It
The council holds the answer, so ask it for its planning guidelines before any tank goes in. A Brisbane home may need planning, plumbing or building approval, depending on where the block sits, how big the tank is and where it goes.
The bushfire overlay code and extra rules for tanks plumbed inside the house may also bite. What that means in practice:
First step
ask the council first, before the tank is ordered, and get its rules for your block in writing.
Sign-offs
one, two or all three approvals can apply, so check rather than assume.
Standards
the plumbing must meet the state development code for tanks and other supplementary water supplies, which sets the performance requirements the work has to satisfy.

Tanks on Newmarket Blocks
The suburb averages about 1,013 mm of rain a year, so a tank here refills steadily across the storm season. At the last census, 54.6 per cent of homes were detached houses, which means most blocks have room for a tank.
The townhouses and units make up most of the rest, and there a slim tank plumbed to one cistern or the laundry is the usual fit. One local wrinkle: a large share of the older streets sits under the council's traditional building character overlay, and that can affect where a tank is allowed to stand. Worth settling with the council before the tank arrives, not after.

Keeping a Tank Mosquito-Proof and Clean
Three clocks govern tank upkeep: the diverter every three months, the screens and roof every six months, and sediment on a cycle of two to three years. Let mosquitoes breed in a tank and the owner can cop an on-the-spot penalty worth up to 3 penalty units. The checks in detail:
Every three months
give the diverter a rinse, and clear it out again after each decent rainfall.
Every six months
check the screens and flap valves for tears and fix any straight away. Clear leaf build-up from the roof and prune overhanging branches. Close any gap that animals, birds or insects could squeeze through.
On a two-to-three-year cycle
check inside the tank for sediment. If sludge coats the bottom, siphon it away or drain the tank right out.
A tank line is pressurised plumbing like any other, so if a run starts weeping where you cannot see it, our leak detection page explains how we trace it. And if a storm splits a line, burst pipe repairs cover the urgent side of the same pipework.

Rainwater Tank Questions From Newmarket Homes
Call (07) 3524 0766Does a rainwater tank in Newmarket need council approval?
Yes, sometimes. One or more council sign-offs can apply to a Brisbane home, depending on the block, the tank's size and its position, and the bushfire overlay code may also bite. Ask the council first, before the tank is ordered.
Can I connect a rainwater tank to my toilet myself?
No, a licensed plumber must make that connection. Running tank water to a cistern or a washer tap is regulated plumbing work, so an owner on a Brisbane property cannot do it alone.
What can I use rainwater from a Newmarket tank for?
Flushing cisterns, filling the washer's cold tap and watering the garden, because the disease risk from these jobs is low. Drinking, cooking and washing stay on town water, which is the safer supply where it reaches you.
Does my rainwater tank need mosquito screens?
Yes, each vent and opening, the overflow pipe included, needs a screen or flap valve that blocks mosquitoes. Brisbane specs want gaps below one millimetre, using stainless steel or aluminium mesh that lifts off for cleaning.
How do I deal with sludge at the bottom of my tank?
Check inside the tank for sediment on a cycle of two to three years. If sludge coats the bottom, siphon it away or drain the tank right out.
