Abstract Assessment of the impact of odours released from sewage pumpstations requires the consideration of a number of factors. These include the determination of the odour emission rate or source strength of the pumpstation, the dispersion of odorous air from the station and the response of the human nose to sewage odour. By using the dilution-to-threshold concept, the odour concentration of ambient air can be quantified in terms of standard odour units per unit volume. Taking into account the rate of odorous air emitted from a sewage pumpstation, the odour source strength of the station can be conveniently expressed in terms of standard odour units per unit time. Field measurements were carried out at ten sewage pumpstations and the results of these investigations indicate that odour emission rates tend to increase with the 1.3 power of the sewage flowrate. Thus, the potential odorousness of a sewage pumpstation is dramatically increased with increasing flowrates. However, because the magnitude of observed change in odour intensity by the human nose is logarithmically related to the magnitude of the odour concentration, perceived odour intensities in the neighbourhood of pumpstations that receive increased flowrates, increase less dramatically.
