Substitution of drinking water by rainwater or gray water for flushing of toilets in house holdings

    Project Details

    Description

    The reduction of the groundwater resources, and maybe also the increasing drinking water prizes, have increased the interest for collecting rainwater for use in toilet flushing or laundry. However, there is little knowledge of the hygienic quality of the collected and stored rainwater and of the hygienic consequences of this use. Therefore several rainwater collection systems and gray water reuse systems for use in toilet flushing established in different parts of Denmark are investigated with respect to occurrence of a range of microorganisms: bacteria, fungi and protozoans.
