Learn how to lay the correct base for your Tanksalot corrugated steel water tank.

A retention water tank is designed to capture and store stormwater runoff for later use. It retains the water on-site, preventing it from immediately entering the drainage system. This stored water can be used for irrigation, landscaping, or other non-potable purposes, contributing to sustainable water management practices. Retention tanks help reduce the demand on municipal water supplies and mitigate the impact of urban development on local water resources.

A detention water tank is primarily focussed on controlling the flow and release of stormwater to prevent flooding and erosion. Detention tanks temporarily hold and slowly release stormwater into the drainage system at a controlled rate. This helps manage peak flows during heavy rainfall, reducing the risk of downstream flooding and erosion.

Seismic restraints are designed to secure water tanks and prevent them from tipping, sliding, or overturning during an earthquake. The ground shaking during seismic events can pose a significant risk to the stability of structures, including water tanks, and securing them is essential to ensure public safety and the integrity of water supply systems. Seismic restraints also help minimise the risk of damage to the tank itself and reduce the potential for water contamination or loss.
