One tank, many jobs
Water storage for every need
From a household reserve to a construction site, a farm, or a commercial block — the same seamless shell, sized and fitted for the job.
Domestic Water Storage
Keep a reliable reserve for the household through rationing, dry spells, and supply interruptions — from a 1,000L tank to a 24,000L installation.
Loft & Roof Tanks
Rectangular loft tanks from 230L to 920L designed to fit into roof spaces and tight service voids without wasting floor area.
Farming & Irrigation
Hold water for livestock, greenhouses, and irrigation lines. Poly tanks resist fertiliser and farm chemicals that corrode metal.
Underground Storage
Bell-shaped underground tanks from 1,000L to 6,000L keep water cool and out of the way where surface space is at a premium.
Commercial & Construction
Large-capacity tanks for hotels, schools, apartments, and building sites that need dependable on-site water storage.
Waste & Sanitation
Septic tanks from 1,700L to 6,000L and sanitation products moulded as one seamless piece, so nothing leaks or corrodes underground.
