Bespoke One Piece Tanks

Not all tank installs are clear cut. In particular, where tanks are required for existing plant rooms or an old galvanised water tank needs replacement, our standard range of one piece water tanks, may not fit due to space or access restrictions. We can provide our clients with an alternative bespoke manufactured water tank. We will work closely with you to design a customized water tank based on your specific, site and water capacity needs.  Like our standard one piece tank range, we can manufacture them, insulated to Format 30 for potable water and un-insulated for grey water applications. Similar to bespoke water tanks, we can design and manufacture replacement GRP water tank lids and condensation trays.
