Australian manufacturer Clark Tanks build rain water tanks

that are designed to withstand the harsh Australian weather while remaining affordable. Our poly tank range includes small tanks and large tanks and various styles including round tanks, slimline tanks and underground tanks. There are several reasons why you should speak to Clark Tanks when considering your next rain water tank purchase. First and most importantly, we are longstanding manufacturers of water tanks that are proven, well-known and trusted to last. Secondly, our superior one-piece poly construction with ribbed profile and tapered wall means your water tank is built strong, and your rain water is protected from mosquitoes, untainted by fibres found in other materials and tastes fresh. Thirdly, your rainwater tank is manufactured to exceed the highest Australian tank quality standards as well as pass NATA capacity tests. If designing tanks to exceed Australian standards, offering numerous tank sizes and styles including our round tank, slimline tank and underground tank ranges, was not enough; Clark Tanks also provide an industry leading 25 year tank warranty. Clark Tanks have been around since 1997, before the tank business boom brought on by Australia's recent droughts and water shortages. You can be confident knowing choosing a renown manufacturer that your warranty will still be valid many years from now. This is one reason why many builders use Clark rain water tanks for their projects - whether round or slimline water tanks. So whether you live in northern Queensland or at the southern end needing Brisbane water tanks, or if you live in NSW and are looking for Sydney water tanks, or perhaps even further south in Victoria requiring Melbourne water tanks, we provide free water tank delivery to most areas. Our friendly and experienced staff also take pride in consistently offering the best advice and service when it comes to your storage tank, whether you are a home owner, a farmer or industry in need of storing chemicals and waste.
