Abstract
In Winnipeg, greywater reuse, if applied broadly, could become a water conservation alternative having the potential to delay or eliminate the need for a supplemental water supply source and reduce future water treatment costs. The Opportunity/Constraint Analysis Method is comprised of three levels of information which must be considered in a preliminary assessment of feasibility for greywater reuse retrofit. These are: (i) planning issues related to the institutional or regulatory/policy environment (focusing on public health, environment, building/plumbing codes, sewer utility by-laws, infrastructure/public works and zoning); (ii) site specific information related to the building environment in question (focusing on general facility information, current water usage and existing equipment/infrastructure); and (iii) solution generation related to possible reuse options (focusing on appropriate reuse possibilities, pre-design considerations related to public health protection and operating and maintenance requirements and preliminary costing). Specific areas of concern or protocols were identified for each of the focus areas listed under the three levels of information. Presented as a three-part checklist, each part of the Opportunity/Constraint Analysis Method corresponds to the three levels of information and lists the related focus areas and specific protocol related to each.
