Allcast Precast is the solution for your plunge pool, septic tank and water tank needs. We manufacture all of our tanks in concrete because it has excellent insulating properties and keeps water cool in hot weather. Concrete tanks don’t rust, leak or cave in, and reduces the risk of algae or bacteria growth in the water. Our concrete water tanks are long lasting, low maintenance and fire resistant. For aesthetic purposes our water tanks can be installed above or underground, and fitted with camlock valve fittings for use of fire-fighting purposes.
