“…As shown in Table 1, the results of the model reinforce what other studies have already noted. For example, the results of the model showed that the rate of adoption of water conservation technologies under various scenarios can lead to a 3-10% reduction in the overall water demand of the City of Miami Beach; this outcome is consistent with the findings of a study conducted by [68] that analyzed the impacts of the water conservation incentives on water demand in Miami-Dade County through surveys among the households. This study reports that about 6-14% reduction in water demand was achieved during the implementation of two 4-year water conservation incentive programs in this area.…”

More than one billion people will face water scarcity within the next ten years due to climate change and unsustainable water usage, and this number is only expected to grow exponentially in the future. At current water use rates, supply-side demand management is no longer an effective way to combat water scarcity. Instead, many municipalities and water agencies are looking to demand-side solutions to prevent major water loss. While changing conservation behavior is one demand-based strategy, there is a growing movement toward the adoption of water conservation technology as a way to solve water resource depletion. Installing technology into one's household requires additional costs and motivation, creating a gap between the overall potential households that could adopt this technology, and how many actually do. This study identified and modeled a variety of demographic and household characteristics, social network influence, and external factors such as water price and rebate policy to see their effect on residential water conservation technology adoption. Using Agent-based Modeling and data obtained from the City of Miami Beach, the coupled effects of these factors were evaluated to examine the effectiveness of different pathways towards the adoption of more water conservation technologies. The results showed that income growth and water pricing structure, more so than any of the demographic or building characteristics, impacted household adoption of water conservation technologies. The results also revealed that the effectiveness of rebate programs depends on conservation technology cost and the affluence of the community. Rebate allocation did influence expensive technology adoption, with the potential to increase the adoption rate by 50%. Additionally, social network connections were shown to have an impact on the rate of adoption independent of price strategy or rebate status. These findings will lead the way for municipalities and other water agencies to more strategically implement interventions to encourage household technology adoption based on the characteristics of their communities.

“…Domene and Saurì [28] demonstrated that consumer behavior was an important explanatory factor in household water consumption, albeit to a lesser extent than other variables (e.g., socio-demographic and economic variables, such as house type and income). Nieswiadomy [46], Michelsen et al [47], Hurd [48], Lee et al [49] and March et al [50] found a discernable influence of the existence of water-conservation programs on water demand. Nauges and Thomas [22] reported that residential water consumption was significantly lower when individual housing with meter recording was present, and they thus encouraged the installation of water metering in collective housing.…”

Abstract:The aim of this study was to estimate the determinants of residential water demand for chief towns of every Italian province, in the period 2007-2009, using the linear mixedeffects model estimated with the restricted-maximum-likelihood method. Results confirmed that the applied tariff had a negative effect on residential water consumption and that it was a relevant driver of domestic water consumption. Moreover, income per capita had a positive effect on water consumption. Among measured climatic and geographical features, precipitation and altitude exerted a strongly significant negative effect on water consumption, while temperature did not influence water demand. Further, data show that small towns in terms of population served were characterized by lower levels of consumption. Water utilities ownership itself did not have a significant effect on water consumption but tariffs were significantly lower and residential water consumption was higher in towns where the water service was managed by publicly owned water utilities. However, further research is needed to gain a better understanding of the connection between ownership of water utilities and water prices and water consumption.

“…Kenney et al (2008) and Renwick and Green (2000) found similar reductions associated with participation in water efficiency rebate programs. Additionally, several studies have used summary statistics to estimate a 6% to 16% reduction in residential water demand from adoption of efficient technologies (Lee et al, 2011(Lee et al, , 2013AWWA, 1999;.…”

Summary Potable residential water efficiency and reuse technologies have seen increasing adoption in recent years and have been estimated to reduce demands by up to 50%. In this work, we used an engineering economic model to estimate the technically feasible levelized cost of water provided by seven above‐code water efficiency (i.e., beyond that required by building code) and reuse technologies within the Lower Colorado River Authority (LCRA) in central Texas. Unlike other demand‐side studies of residential water use, we model uncertainty and variation in technology adoption cost and performance; include reuse technologies; and differentiate between new construction and retrofits. We developed a conservation supply curve to compare the levelized cost of efficiency and reuse technologies with conventional supply‐side water management strategies. We estimate that efficiency and reuse in the residential sector can meet 85% of 50‐year projected needs (the difference between projected demand and estimated supplies) for the LCRA service area. We also estimate lower levelized costs for immediate retrofits of most technologies, promoting incentives for early technology adoption. However, efficiency and reuse technology performance demonstrates considerable uncertainty and variability. The fraction of demands met by demand‐side strategies range from around 60% to 100%. Occupancy drives much of the variability because it significantly affects demand. These results promote designing incentives for adoption of water efficiency and reuse technologies based upon use. We find that water‐efficient showerheads and bathroom faucet aerators perform well over a variety of assumptions, indicating that these technologies should be a priority for municipalities seeking water demand reductions.
