Rainwater tanks in Mt Ousley
Are you located in the Mt Ousley area and need rainwater tanks, slimline tanks or round water tanks?
Well, look no further. ABC Seamless has supplied and installed rainwater tanks across the Illawarra for more than 50 years, and we know how to match the right tank to your Mt Ousley home. The Illawarra receives heavier rainfall than Sydney, so capturing stormwater in a quality tank makes real sense - whether you are watering a garden, filling a pool, or reducing mains water use on a ridge property.
We supply and install both Slimline and round water tanks, each suited to different blocks and budgets. All tanks carry substantial warranties and are made from UV-stabilised food-grade polyethylene, built to last in our coastal climate and heavier rain patterns.

Rainwater Tanks for Mt Ousley homes
Slimline tanks for tight coastal blocks
Many Mt Ousley homes sit on tighter blocks where a traditional round tank simply will not fit. Our Slimline tanks are the answer. They slide neatly into narrow side access, making them ideal for coastal and suburban properties where space is at a premium. The Slimline Brain Tank holds 2500 litres and comes with an internal pump, so you can direct stored water exactly where you need it - to garden beds, outdoor taps, or washing systems.
Round water tanks for larger properties
If your Mt Ousley block has more room, round water tanks offer excellent storage capacity and stability. Round tanks suit larger residential lots and properties where you want higher volume stormwater capture. They are simple, robust, and perform beautifully in the Illawarra's heavier rainfall conditions.
Food-grade polyethylene and long-term durability
Every tank we install is made from UV-stabilised food-grade polyethylene, protecting your stored water from algae, debris, and degradation in our salt-air coastal environment and strong sun. The UV stabilisation means your tank resists cracking and discolouration, even after years of Illawarra weather. All tanks carry substantial warranties, giving you confidence in your investment.
Connect your tank to clean guttering and downpipes
A rainwater tank only works as well as the system feeding it. Pairing your new tank with sound guttering and downpipes ensures clean water capture from your roof. We can also fit gutterguard to keep leaves and debris out of your system, so your stored water stays pure and your tank runs trouble-free.
Rainwater tanks work best when paired with quality guttering, downpipes, and gutterguard to protect your water supply.
