AbstractA combination of the Environmental Protection Act 1990 and the water companies being more in the public eye since privatization seems to have heightened public awareness and sensitivities to unpleasant odours emanating from sewage‐treatment works. The incorporation of odour‐control measures is therefore increasingly becoming a condition of planning consent.The selection of the correct odour‐control system for each application is of paramount importance, and the two principal criteria are that (i) it should be effective in its performance, and (ii) it should be cost effective to install and operate.This paper does not explore the advantages and disadvantages of the various types of odour‐control system, but concentrates on the case study of one particular application where these criteria have been met by using multi‐stage chemical scrubbing. The source and nature of the odours, containment, ventilation, treatment and performance are described, concluding in an assessment of 'cost of ownership'.
