Bio-Envirotank Bunded Fuel Tank

Carefully developed for the future with an inner fuel storage tank externally stiffened and with a sloping hopper style bottom. Bio-Envirotank's fuel tank design comprises a primary storage tank without internal structure to enable ease of cleaning and internal inspection. The primary fuel tank is enclosed by an outer steel bund that fully complies with the control of pollution regulations. The base of the bunded fuel tank has a sloping hopper style bottom to a sump. The sump is serviced by a 25mm sludge drain pipe accessible from the tank top. The incorporation of sloping bases and sumps helps reduce the frequency of tank cleaning as water and contaminants will easily drain into the sump. Residues are extracted via the sludge drain pipe which runs from the tank top to the sump.
