We have a large one of these tanks which we would like to clear. It's half as tall again as the one shown here and of a size we no longer make. It's for the Zero Discharge toilet and will take around 11,000 toilet uses before it needs to be pumped out.
All the other components you need will be supplied with it and the whole package is available for £3000 + VAT and delivery (you install). This is less than the cost of our current ZD model utilising the tank shown here which is listed at £3550 + VAT and delivery, installation not included.
