Membrane-covered wastewater tanks
A membrane-covered wastewater-tank enquiry needs a clearly defined purchase. Establish whether it concerns the cover above the tank or a complete project including the tank and equipment.

Define contract and drawing boundaries first
List tank, foundations, membrane cover, ventilation and collection, and accessories separately. Check their interfaces after responsibilities are clear so excluded work is not mistaken for included scope.
- Does the purchase include tank construction?
- Who provides information for the connecting interfaces?
