Question: What is a pumped outlet?

Answer: A pump is fitted into the Marsh ENsign domestic sewage treatment plant, where there is no natural fall of gravity from the outlet pipe. So the pump allows the effluent to be pumped to a higher level, we recommend the compressor is sited externally when a pump is fitted, together with a high level alarm. The Marsh ENsign design means that the pump is easy to fit and accessible and means a separate pump chamber does not need to be installed saving both money and time.
