“…Moreover, frequent stoppages in water supply to repair breakages, which occur due to the poor condition of the networks, lead to a welfare loss. In Spain, the welfare loss is larger under a supply interruption than price rises [35]. In any case, the necessary increase of urban water tariffs should be gradual and progressive over time; and should protect households at risk of social exclusion by ensuring access to water resources.…”

Abstract:Recently, in the context of the Integrated Water Resources Management, demand policies are playing a more important role as opposed to traditional supply policies based on the construction of large hydraulic infrastructures. In this new context, water tariffs have become an important tool in achieving economic efficiency, environmental sustainability, and social equity. This paper reviews the situation of urban water tariffs in Spain, a country subject to high water stress. It analyzes the capacity of urban water tariffs to recover service costs and to promote efficiency, sustainability, affordability, and equity. Although it has made significant progress in recent years, the Spanish urban water tariff system still faces many challenges. Many of these challenges would be better addressed by a national independent regulatory body.

“…Pricing policies have received much attention by economists who consider the price to be the best instrument to induce water conservation because the welfare loss of water restrictions usually exceeds that of a price increase (Woo, 1994;Roibás, García-Valiñas and Wall, 2007;Grafton and Ward, 2008). However, because residential water demand is known to be price inelastic, managers of water utilities have often preferred to impose restrictions on water use instead of imposing higher prices.…”

Using unique survey data of 10,000 households from 10 OECD countries, we identify the driving factors of household adoption of water-efficient equipment by estimating Probit models of a household's probability to invest in such equipment. The results indicate that the adoption of water-efficient equipment is the most strongly affected by ownership status, by being metered and charged a volumetric charge on water consumption, and by behavioural factors. Environmental attitudes are strong predictors of adoption of water-efficient equipment, with a marginal effect that exceeds ownership status in some cases. In terms of policy, we find that households that were both metered and charged for their water individually had a much higher probability to invest in water-efficient equipment compared to households that were not charged for their water.

“…Reductions in water consumption may also be highly variable, from 5 to almost 20 % in certain cases . More positive effects appear to be related to the intensity of campaigns (Wang et al, 1999) or when awareness campaigns are implemented together with other measures such as pricing (Nieswiadomy, 1992;Roibas et al, 2007). Furthermore, the success of awareness campaigns, especially in the long run also appears to be strongly related to the frequency and severity of drought conditions (Wang et al, 1999).…”

Abstract. The design of water awareness campaigns could benefit from knowledge of the specific characteristics of domestic water use and the factors that may influence certain water consumption habits. This paper investigates water use in 450 households in 10 municipalities of drought-prone Alicante (Spain). We aim to increase knowledge about existing domestic water behaviors and therefore help to improve the design and implementation of future water awareness campaigns and even to consolidate reductions in water use after drought periods. The survey suggests that awareness campaigns should revise their scope and their channels of diffusion on a regular basis. In a more specific way, for the Alicante case we propose policy-oriented recommendations on the scope of action for further reductions.
