Modular Tank System

Modular underground water storage systems are retention or detention tanks that can handle any volumes of water, from vast to massive.

Modular systems are manufactured from 100% recycled plastics which have been designed with a unique interlocking capability, this allows Sub terra to design a tank to any size, shape and specifications your site calls for. Around trees, under sports fields, beneath major roads or as a complete watering system for parks and gardens.

Modular underground water storage tanks are fast and simple to install. The modular, inter-connecting style allows most of the tailoring and assembly to be done off-site. Once delivered, the erection is simple and the free-form structure can be as shallow as 0.1m and as deep as 2.5m, with any length and width in 1m increments.

Unlike pre-cast tanks, there are no restrictions on shape and size and the tanks can be used for a great variety of purposes like fire protection, manufacturing plants and irrigation.

Once modular underwater storage tanks are installed and re-surfaced with turf, bitumen or artificial turf, they seemingly disappear. Your park, your sports ground or your road can resume normal activities.
