Concrete water tanks are widely used for rainwater harvesting and general bulk water storage, offering advantages related to purity and temperature control.
Key Benefits
- Exceptional Durability and Longevity:
- Water Quality and Purity:
- Concrete is chemically inert and does not taint water with metal or plastic by-products, ensuring the stored water remains clean.
- The alkaline nature of concrete can also help neutralize slightly acidic rainwater (beneficial for pipes and taps).
- Temperature Control and Algae Elimination:
- Concrete is a dense material that provides excellent thermal mass, which naturally keeps the water cool.
- The combination of coolness and the ability to bury the tank means that algae growth is virtually eliminated , which in turn leads to:
- Fewer problems with pumps, valves, and filter clogging.
- Capacity and Aesthetics:
- Concrete allows for large volume capacities suitable for commercial, agricultural, or large residential needs.
- Tanks can be buried 90–100% underground. This minimises the visual impact on your property, often showing only the lid (as little as 100mm) above ground.
- Environmental Profile:
- Concrete is comprised of relatively environmentally friendly materials (water, aggregate, and cement), giving it a favorable environmental profile compared to some plastics.
