The Slimline Poly Water Tanks are engineered with lightweight and tough materials to provide you with a durable water storage solution that you can count on. Their low-profile designs allow you to store them under your deck or window for easy access to rainwater. A good solution for narrow passageways or for areas that might be difficult to get a larger, bulkier tank to, the poly slimline tanks allow you to utilise the available space to your fullest advantage. Some of these tanks can be manifolded together with other tanks alongside the walls so that you can achieve larger amounts of rainwater storage. These tanks can hold from 720 litres to 5,000 litres.
