Septic tank
While a properly maintained and located septic tank does not pose any more environmental problems than centralized municipal sewage treatment, certain problems can arise with septic tanks in unsuitable locations. Since septic systems require large drainfields, they are not suitable for densely built areas.
Diesel fuel tanks in trucks
Important considerations in designing a diesel fuel tank are determining placement, choosing the shape and calculating the required volume. Side mounting is the most common placement of diesel tanks for trucks. This is typically accomplished with the use of brackets, straps or a combination of both for the purpose of attaching the fuel tank to the truck frame.
