|The units compli 1500 and 2500 have been designed for the disposal of sewage from industrial, public and semi-public buildings, apartment blocks, flats, etc. for an uncontrolled effluent flow and specially where a safety factor must be provided. The entire unit is damp- and flood proof and thus ideally suited to placing in unventilated areas or basements subject to accidental flooding. |
