Sustainable sewerage servicing options for peri-urban areas with failing septic systems

摘要

The provision of water and wastewater services to peri-urban areas faces very differentnchallenges to providing services to cities. Sustainable solutions for such areas are increasinglynbeing sought, in order to solve the environmental and health risks posed by failing septicnsystems. These solutions should have the capability to reduce potable water demand, providenfit for purpose reuse options, and minimise impacts on the local and global environment.nA methodology for the selection of sustainable sewerage servicing systems and technologiesnis presented in this paper. This paper describes the outcomes of applying this methodology tona case study in rural community near Melbourne, Australia, and describes the economic andnenvironmental implications of various sewerage servicing options. Applying this methodology hasnfound that it is possible to deliver environmental improvements at a lower community cost, bynchoosing servicing configurations not historically used by urban water utilities. The selectednsolution is currently being implemented, with the aim being to generate further transferablenlearnings for the water industry.
