Andel’s underground HDPE rainwater harvesting tanks are a reliable, environmentally-friendly solution for collecting and storing rainwater from rooftops, paved surfaces and other drainage areas.
Captured rainwater can be reused for a variety of non-potable applications, reducing reliance on mains water and helping to cut utility bills.
Andel rainwater harvesting tanks are installed underground and can be used for a variety of purposes such as irrigation, domestic use and groundwater recharge.
Water harvesting is environmentally friendly by conserving water resources, reducing stormwater run-off and mitigating the risk of flooding.
Using harvested rainwater contributes to greater water security and sustainable development.
Monolithic HDPE body – Rotationally moulded in a single, rib-reinforced piece for maximum strength and structural integrity.
Chemical and impact resistant – HDPE offers outstanding resistance to corrosion, fuels and mechanical stress – yet remains lightweight for fast, safe handling. Far more durable and damage-resistant than traditional GRP alternatives.
Low-maintenance, cost-efficient – One-piece construction with no internal components to replace means fewer installation issues, minimal servicing, and lower lifetime costs.
Incoming rainwater is routed through a pipe system into the tank. A dual filtration setup – including a top filter and internal filter basket – removes both organic debris and inorganic particles – such as leaves and sand. Clean, filtered water is stored in the tank and supplied to the draw-off point.
Tanks are fitted with an overflow mechanism which means that during heavy rainfall if the tank is full, any excess water is safely discharged into the stormwater drainage system. Rainwater harvesting tanks can be part of a garden irrigation system or power supply for domestic sanitary installations.
Andel offers a range of rainwater harvesting tanks with or without pumps from 2,000 to 5,000 litres to suit residential, commercial and agricultural installations.
All tanks are designed with ease of installation in mind, making them ideal for both new developments and retrofit projects.
Andel's rainwater harvesting tanks provide efficient, sustainable water storage for every environment, protecting resources, reducing flood risk and promoting water sustainability
It collects and stores rainwater from rooftops, gutters, and other drainage areas for future use, reducing reliance on mains water and promoting sustainable water management.
They are built from one-piece, lightweight, high-density polyethylene (HDPE), known for its strength, impact resistance, frost resistance, and chemical resistance.
Andel offers a range of rainwater harvesting tanks from 2000 litres to 5000 litres capacity.
The collected rainwater can be used for various purposes such as irrigation (gardens), domestic uses (e.g., toilet flushing, washing machines), and groundwater recharge.
Underground installation helps keep the water at a constant, cool temperature away from light, reducing the risk of discoloration or bacterial growth, and without compromising landscape.
Yes, they feature an integral self-cleansing filter system and a calmed inlet to prevent sediment displacement.
Tanks are fitted with an overflow mechanism that redirects excess water into the stormwater drainage system once the tank is full, helping to mitigate flood risk.
Andel rainwater harvesting tanks are available with or without pumps.
