Abstract

Water shortages and increasing urban densities are the main drivers that are challenging many developed regions to consider alternative decentralized strategies such as rainwater harvesting, greywater re-use/recycling, sewer mining, urine separation and water demand management to control urban water services. The source management strategies which are implemented in residential area are likely to change sewage quality and quantity in sewer pipes since domestic sewage contributes 60% of the total sewage flows. Several past studies confirmed that the implementation of source management strategies successfully decrease the sewage flow and subsequently increase the sewage strength. Alteration of sewage quantity & quality can cause sewer problems such as blockage, corrosion and odour. An extensive literature study indicates that sewer problems associated with source management strategies can be qualitatively assessed. The results show that water demand management, sewer mining, greywater re-use/recycling and urine separation might potentially contribute to blockage and corrosion/odour in sewer network, while rainwater harvesting might reduce corrosion/odour. ----This is a publication of two conferences - the '33rd Hydrology and Water Resources Symposium and 10th Conference on Hydraulics in Water Engineering' and the '34th World Congress of the International Association for Hydro- Environment Research and Engineering'
