Water diaries: a participatory approach to generating gender disaggregated intra-household water use data
Effective domestic water sector management and policy development requires quantitative and qualitative intra-household water use data. However, there are currently limited methods, and efforts, to collect such data. This paper outlines the Water Diary, a participatory research method to generate intra-household water use data. Combining self-reported individual water use and ...

Tackling water losses through improved domestic water bills
The domestic water bills that municipalities send out to consumers on a monthly basis are a key interface between local government and citizens. Being a legal instrument, as well as a communication medium, the consumers' level of understanding of their water bills and the confidence in the information provided is therefore indicative of their effectiveness. A lack of understanding of bills ...

Cost recovery in times of demographic change: Portugal's domestic water policy
Cost recovery is a key tenet of the Water Framework Directive, but scalar implications of this in the domestic water sector are rarely addressed. It is more expensive to supply water services to rural populations owing to cost of provision across areas which are extensive yet sparsely populated; however, residents in rural areas often have lower incomes than urban populations. Taking the case of ...

Big Water needs 'little' people: improving water resource management by including households
Amid claims that the global water crisis is a management crisis, rather than a crisis of resource scarcity, ADB (2010) strongly indicates that contemporary water management institutions are failing to sustainably manage water resources. The burgeoning domestic sector offers a rich environment to examine some of the failings of institutional water resource management, with increasing ...

Evaluation of statistical sampling for the assessment of residential consumption totals in water distribution networks
The paper provides insights into stratified sampling, a standard statistical technique that may be employed to assess domestic water use in water distribution networks. The basic idea is to use only a few meters to provide inference on the total water consumption of a network or of a district metered area through the knowledge of some additional stratification variables, such as household ...

Foreign funding-induced development, institutional weakening and access to water: a case study from Kerala, India
Water governance is a multifaceted political and administrative practice across the world. The domestic water management policies of developing societies are subjected to global water politics: institutional change due to foreign aid in Kerala's water governance proves this relationship. Foreign aid has shifted the control of rural drinking water supply from government to the community. ...

Water Diaries: generate intra-household water use data – generate water use behaviour change
With the current ‘water crisis’ essentially a crisis in water management, the need to clearly understand domestic water use is critical. In recent years there has been a growing awareness of the need to manage demand in all water sectors. However, demand mechanics at the intra-household scale are not well understood, with many utilities adopting a ‘command and control’ ...

Alternatives for domestic water tariff policy in the municipality of Chania, Greece, toward water saving using game theory
As defined in the EU Water Framework Directive, every water tariff policy should be fair toward customers, generate legitimate revenue, and motivate consumers toward water saving. In the city of Chania, Greece, the inhabitants have asked for a fairer tariff policy and exhibited the intention to save water under the implementation of stricter measures. Therefore, a two-person zero-sum game was ...

Assessment of domestic consumption in intermittent water supply networks: case study of Puerto Ayora (Galápagos Islands)
Intermittent water distribution systems are a stark reality in developing countries. Puerto Ayora, the centre of tourism of the Galápagos Archipelago, is not an exception, with its population and tourists suffering from scarce water resources. However, the extreme per capita consumptions, well above those in 24/7 supply situations in many other countries, contradict the (sense of) scarcity. ...
