Implications of Surcharge on the Operability of Sewer Networks
Thames Water Utilities Limited is the largest water company in the United Kingdom, providing 2600 million litres of treated water for its 8 million clean water customers and treating 4200 million litres of sewage daily for its 13 million waste water customers, in London and across the Thames Valley. Significant lengths of the network are likely to be over 100 years old and their remaining life expectancy is unknown. In general, as the pipeline ages there is a higher likelihood of failure occurring. There are a variety of factors that influence the deterioration of sewers but the mechanisms which cause these failures are not fully understood. The identified mechanisms of interest include infiltration and exfiltration. These mechanisms can occur at the sewer joints and can be exacerbated during surcharge. This paper presents a literature review of information available on the mechanisms and their perceived main influences. In essence, it is understood that exfiltration could potentially lead to environmental pollution, whereas infiltration could result in operational problems both in the network and at treatment works. There is little published work on issues concerned with these mechanisms and accordingly, there are obvious benefits in investigating these topics further.
