Hello Daff Hubb, When designing and building tanks, our first priority is that of strength and longevity. Due to the complex internal structure, efficient pump-out may require more attention than what is usual. One benefit of our design is that we include many inspection/service points thus ensuring good access to all areas of the tank. Our focus is on tank design and we do not offer pump-out service, which should be performed by qualified and experienced contractors, the best of whom would have no issue with our more complex designs. We are always open to client comment and recommendations so feel free to communicate with us if you have something constructive to contribute. Malcolm.
