Guidance Notes on Discharges from Village Houses

Disposal of sullage
19. For village houses built after 1984, the STS's should have been designed to receive both sullage (i.e. wastewater from a bath, shower, sink or basin) and toilet waste. However, for older village houses, most of the STS's had been designed to receive only toilet waste. For some old village houses, no STS had been provided at all. Sullage from these older village houses is commonly discharged via surface channels to the nearby streams. Disposal of sullage into surface channels can only be tolerated if this does not result in pollution. Where necessary, the EPD may require the responsible householder to install proper facilities (e.g. a new STS) or extend the existing STS for the disposal of both toilet waste and sullage.
