Description
The 650 Litre Slimline Tank is a practical and highly efficient solution for properties where space is limited but reliable water storage is still essential. Designed with a sleek, vertical slimline profile, this tank fits neatly against walls, fences, garages and outbuildings without compromising on storage capacity, making it ideal for both domestic and commercial environments.
Manufactured from high-quality, UV-stabilised polyethylene, this slimline water tank is built to withstand the British climate, protecting stored water from sunlight degradation and ensuring long-term structural integrity. The material is fully potable, meaning the stored water is safe for a wide range of non-drinking applications such as garden irrigation, vehicle washing and commercial cleaning operations.
Its tall, narrow footprint allows it to maximise storage while taking up minimal ground space, making it perfect for properties with tight boundaries, narrow side access or limited outdoor areas. Whether you’re creating a rainwater harvesting system or simply need an additional backup water supply, this 650 litre slimline tank delivers dependable performance with minimal visual impact.
Common uses include:
- Rainwater harvesting systems
- Garden and landscape irrigation
- Mobile valeting and window cleaning setups
- Commercial premises requiring compact water storage
- Residential properties seeking eco-friendly water management
By collecting and storing rainwater, this tank helps reduce reliance on mains water, lowering utility costs and supporting sustainable water usage. At the end of its life, the tank is fully recyclable, reinforcing its environmentally responsible design.
