Our unbeatable Carat wastewater tank range

Our Carat wastewater tank was designed to enable a precision-fit, welded-in baffle to permanently split the tank into two watertight chambers. The Carat XL (up to 10 000 l) and Carat XXL (up to 122 000 l) wastewater tanks are the largest products in the range. Numerous seals prevent seepage water from entering the tank. Groundwater stability and suitability for lorry loading are evidence of the high static reserves of these robust wastewater tanks.
