Rethinking of Non-traditional Water Resources in Residential Developments of Rural Towns, Western Australia

摘要

Rainwater collected from residential roofs and greywater generated from domestic uses except toilets are viewed as possible substitutes for high grade water sources which supply non -potable indoor uses and irrigation in Australia. This paper searches for alternatives by adopting roofwater and greywater in residential envelope as per Australian water standards. This study provides the results of greywater recycling, which contributes to the greater saving of mains water supply than rainwater use, and which reduces more than 50% of the wastewater to receiving waters in the rural township of Cranbrook, Western Australia. Similarly, capturing rainwater can mitigate approximately 48% stormwater drainage in this study area. This research endeavors to offer a typical paradigm for an integrated water system in the rural residential sectors.
