Tank accessories - what is included?
- Water will have to be pumped out of the tank. In larger tanks the pump can be submersible, whereas in the modules and bladders it's mounted on the ground outside the tank
- Underground tanks tend to be supplied without filters as a custom solution is generally required.In some tanks access is difficult or even impossible, so special efforts need to be made to keep the water entering the tank clean and especially free from organic material
