For this project, we were approached to design and fabricate covers to
be retrospectively fitted to 4 tanks that were the final step in the solids/
sludge process at a Wastewater Treatment Plant, and are used to hold the
processed Bio Solids before the material is sprayed onto nearby pine trees
as a fertiliser. We then teamed up with an Engineering group who had been
tasked with designing the frames over the tanks, and developed a sectional
lid. The design included a reinforced apex with lifting straps, two inspection
hatches and skirt with webbing tie downs to ratchets which were fitted to
the tank walls.
