A performance analysis was carried out to investigate possible implications of reduced water consumption in domestic buildings on site sewers. The methodology, which involved the comparison of current and future water use scenarios for UK conditions, included: determination of typical volumes and discharge flow rates from various house appliances; stochastic modelling to generate likely outflow hydrographs for common household types; as-sessment of suitable design criteria for transport of gross solids in pipes; and hydraulic modelling of sewer networks for up to 10 house connections with a variety of house types, occupancy levels, pipe diameter and gradients. Overall, the study showed that in future, with the increased use of water efficient appliances, there will be only a minimal effect on the drainage system. This conclusion does however depend upon which mechanism is dominant for solids transport in pipes. It is therefore particularly important to recognise the role of maintenance in keeping a satisfactory performance of the site sewers.
