Summary on Grant Application Form
To prevent overloading of sewer networks and sewage treatment plants, combined sewer overflows are used to relive excess sewage flows under storm conditions. These inevitably lead to pollutants of receiving waters and the larger solids or aesthetic pollutants lead to public complaint. Aesthetic pollutants consist of faecal matter, toilet tissue and feminine hygiene products and the project aims to develop an understanding of the production levels of these pollutants in a sewer system by different socio-economic and ethnic population groups. A mathematical model will be developed to describe the production and transportation of these pollutants through the sewer network in terms of population, catchment and sewer network characteristics. The model combines the production and transportation elements to predict the temporal distribution of aesthetic pollutants at a specific point in a sewerage system under storm conditions. The model will be verified by comparison with the results of an in-sewer system under storm conditions. The model will be verified by comparison with the results of an in-sewer sampling programme. The model will then be extended using known combined sewer overflow (CSO) performance data to enable the pollutant loading from individual CSO's to be predicted and compared with regulatory standards to arrive at cost effective solutions to sewerage upgrading proposals.
