| Abstract: | The paper describes the installation of a vacuum sewerage system in a village on the Welsh border west of Shrewsbury. Reasons are given for the choice of system, design criteria, and installation experience, together with observations on the system's performance over the last four years. The scheme is self-contained in that it has a dedicated sewage-treatment works in the form of a proprietary rotating biological contactor, and it is about to be extended in a second phase of vacuum sewerage. |
