Underground Storage Tanks

Underground tanks from JoJo Tanks offer a solution when space and accessibility are an issue – especially in an urban environment. They can be placed under paved lightweight traffic areas e.g. garden paths, garden beds or lawns providing an eco-friendly and aesthetically-pleasing solution for rainwater capture and harvesting.

Like all other JoJo tanks, these underground tanks are manufactured utilising the rotational moulding process to produce a one-piece, seamless, watertight tank. The rugged, ribbed design offers superior strength for underground installation and the rib placement provides exceptional structural integrity.

These high-quality polyethylene tanks are ideal for all liquid and waste storage in agricultural, industrial, commercial and domestic applications.

JoJo Tanks are available for sale through a wide distribution network across South Africa and Zimbabwe.

Rainwater harvesting with underground tanks:

Every time it rains – we lose precious water. Collecting rainwater means you can keep a constant supply of water on hand to supplement your existing water resources or alleviate drought and other unintended water scarcities.

Rainwater harvesting is a simple and cost-effective method of increasing your water availability and lowering your reliance on centralised and municipal water systems. When stored in a JoJo Tanks plastic underground tank, you not only gain access to your saved water but you don’t have to make space provisions for it on your property.
