Assessing storage requirements, water and energy savings, and costs associated with a residential rainwater harvesting system deployed across two counties in Southeast Florida

A nonparametric bootstrapping method for synthetically generating daily precipitation, water supply, and irrigation demand for rainwater harvesting system storage sizing

“…This article describes a nonparametric bootstrapping method that was used to determine household-level rainwater harvesting (RWH) system storage size and reliability outcomes for subsequent use in an analysis of potential savings in water and energy amounts and costs from the widespread deployment of the system across Broward and Palm Beach Counties, located in Southeast Florida, U.S.A., in Wurthmann [1]. The method was implemented in Excel and designed to determine storage size and associated reliability outcomes for RWH systems that provide for the outdoor landscape irrigation demands of single-family detached homes in the regions of interest.…”

“…The method described in the present paper was developed as an alternative to seeking to obtain and implement SARET using rainfall data that does not match the 25-year format required by this tool and then utilize SARET’s output, whose description suggests it might not be ideally suited to the needs of the subsequent analyses to be performed in Wurthmann [1]. In particular, the subsequent analyses called for in Wurthmann [1] require multiple series of numeric output values for storage size and associated reliability outcomes for residential RWH systems in multiple regions, based on bootstrapped mass balance analyses, considering synthetically generated daily rainfall amounts, derived from 11 years of rainfall data, and linked to daily household-level RWH system water supply and irrigation demand values.…”

“…This method was illustrated using the case example of identifying storage sizes and associated reliabilities for RWH systems designed to provide for the outdoor landscape irrigation demands at single-family detached homes in Broward and Palm Beach Counties in Florida. Wurthmann [1] presents the application of this data in a subsequent study, analyzing potential savings in water and energy amounts and costs that could result from the widespread deployment of residential RWH systems for outdoor landscape irrigation in Southeast Florida.…”

Rainwater harvesting system installations required to offset new water demand created by growing populations in Broward and Palm Beach Counties: A dataset for decision making based on numbers of installations, costs, and water and energy savings

“…To account for this uncertainty it is common practice to provide high and low series of population projections, rather than provide just one series of medium projections [2,3,5]. Accordingly, the present and related research articles [1,2,5] developed high and low projections for population growth in Broward and Palm Beach Counties.…”
