AI Article Synopsis
- The paper explores rainwater harvesting (RWH) potential in large urban areas, focusing on a new method to quantify potable water savings (PPWS).
- The proposed method involves four principles: gathering building and municipality types, using an intermediate level for assessment, selecting an upper estimation, and prioritizing RWH initiatives.
- Application of this method to the Paris agglomeration indicates that RWH could save up to 11% of current potable water usage, primarily benefiting the residential sector, which accounts for two-thirds of the PPWS in the region.
Article Abstract
This paper is based on a prospective scenario of development of rainwater harvesting (RWH) on a given large urban area (such as metropolitan area or region). In such a perspective, a new method is proposed to quantify the related potential of potable water savings (PPWS) indicator on this type of area by adapting the reference model usually used on the building level. The method is based on four setting-up principles: gathering (definition of buildings-types and municipalities-types), progressing (use of an intermediate level), increasing (choice of an upper estimation) and prioritizing (ranking the stakes of RWH). Its application to the Paris agglomeration shows that is possible to save up to 11% of the total current potable water through the use of RWH. It also shows that the residential sector offers the most important part because it holds two-thirds of the agglomeration PPWS.
