Important notes
- All dimensions are approximate external measurements — designs and drawings are subject to change.
- Tanks are core-drilled in our factory from a range of standard pipe diameters and positions. You select the sizes and layout that suit your project, and everything is set before dispatch — eliminating site cutting and ensuring accurate, factory-finished results.
- W-suffix models (SW, S+W, LW) include an internal baffle wall, creating a two-chamber tank used as a septic tank or primary settlement tank for domestic sewage systems.
- Any of our tanks can be connected in series using core-drilled inlet and outlet openings to achieve higher combined volumes. This suits many installations, though some system designs may require a single larger tank instead.
