Holding Tanks

 

All Tanks 25% off marked price!!
 

 
All of our blank tanks are ⅜" thick Polyethylene, seamless, roto-molded intended for sewage and water storage.

Holding tanks typically take two-three weeks to arrive from date ordered.

Tanks come blank from the Factory.  We would need a diagram from you showing which of the three dimensions will be length, width, and height.  We would also need the diagram to illustrate what fittings you would like on the tank (inlet/outlet/vent/dip-tube/clean-out/etc), and where you would like them to be located.
