<p>Apparatus for the treatment of effluent discharged by a pumping station comprises a housing (10) accommodating a vessel (24) for storage of a chemical treatment agent and pumping means (26) for delivering the treatment agent in order to dose the effluent therewith. The housing (10) is designed with an integral bund so that any leakage/overflow from the vessel (24) is wholly contained within the housing. A sensor is provided for generating an alarm signal in the event of any such leakage/overflow. An ancillary housing (50, Fig 2) may be associated with the main housing (10) to provide additional storage for the treatment agent. The ancillary housing (50) is also designed with an integral bund. <IMAGE></p> |
