Applications
Water Storage Tanks
Our one-of-a-kind modular tanks provide customisable and scalable underground water storage solutions that are quick to commission and easy to install. Our standard range accommodates up to 9500 litres of storage, but larger systems can be custom-built on request.
Septic Tanks
Modular septic tanks are ideal for installations where increased storage capacity is required. Incorporating the same double chamber design as our standard septic range, they allow for cleaner effluent discharge than conventionally built septic tanks (especially ones built to this scale). They also limit soil and water pollution. Larger systems can also be custom built on request.
Conservancy Tanks
Often used as conservancy tanks, our modular range provides the opportunity to collect and hold wastewater on site while preventing the contamination of groundwater. The stored wastewater is then collected periodically by a waste disposal company and transferred to a suitable treatment plant. Wastewater treatment plants can also be designed to process the water for reuse in non-potable applications.
