Performance indicators for water supply management
In the present study specific performance indicators are proposed that express the level of service of a water system subjected to varying operating conditions over time. The proposed methodology has been applied to a specific case study (Sinni water supply system in Basilicata – Italy) to demonstrate the real applicability of the proposed performance analysis that could be very useful ...

A case study on a quasi-market mechanism for water resources allocation using laboratory experiments: the South-to-North Water Transfer Project, China
The chosen water management mechanism will directly or indirectly determine the success or failure of the South-to-North Water Transfer Project. Due to the importance and complexity of the project and based on national conditions and the water situation, it is necessary to adopt a quasi-market mechanism. Using the advanced experience in China and abroad for reference, this study takes the ...

Inadequacy of positivistic research to explain complexity of water management
The paper looks at alternative scientific research approaches and traditions related to Water Resources Management (WRM) and Water Supply and Sanitation (WSS) services. How can they explain the problem-oriented water governance challenges, and how do they apply to multi- and inter-disciplinary research? It is argued that the bias in favour of a positivistic approach and natural sciences in water ...

A decision support system for water supply emergency management with multiple sources
The construction of water transfer projects brings new challenges to water resources management, especially in water supply security with the use of multiple water sources. However, the operations of water diversion and water supply have been considered in separation in practice. In particular, there are few decision support systems (DSS) designed to tackle the challenges in emergency ...

Self supply systems: Urban dug wells in Abeokuta, Nigeria
Self supply systems are privately owned household water sources. The systems are generally perceived as playing a role in water service delivery to the rural poor. The systems' yielding safe drinking-water also receives little attention in literature and policy, relative to public and communal sources. This paper assessed urban self supply wells and argues that self supply is a coping water ...

Policy recommendation for drinking water supply cross-border networking in the Adriatic region
Cross-border water resources and drinking water supply management are among the basic concerns for almost all Adriatic Sea countries. Adopting measures such as developing common methodologies, tools and techniques addressing water quality and quantity issues, water losses and pricing policies is a top priority. Regarding the harmonization of procedures and legislative framework, the ...

Success or failure: demonstrating the effectiveness of a Water Safety Plan
The Water Safety Plan (WSP) concept has become a globally recognised and accepted approach to drinking water supply management and operation. Many countries around the world are adopting this proactive, risk-based model for ensuring consistent confidence in drinking water safety, accessibility and affordability. While it is widely accepted that the WSP concept is an appropriate tool for ensuring ...

Geodrilling: Managing Water Supply in Italy
In recent years there has been significant reorganisation in the Italian water sector to conform to the rules set out in the European Union Water Directive concerning the control of water pollution and the consistency of water tariffs. There have been some successes, particularly where companies in the industrial and commercial sectors, who manage their own water supplies, have had some ...

Discovering Reservoir Operating Rules by a Rough Set Approach
An integrated Rough Set approach is proposed and implemented to discover the historical operating rules of a Sicilian irrigation purpose reservoir. Operating rules are derived by expressing monthly releases from the reservoir as functions of stored volume, inflowand release during a 35-years period. This is accomplished through the Rough Set approach as implemented in the Rose package and the use ...

Determinants of household participation in the management of rural water supply systems: A case from Ethiopia
Access to safe drinking water supply in Ethiopia is among the lowest in sub-Saharan Africa. While both governmental and non-governmental organizations have implemented water supply projects in recent years, many fail shortly after construction due to improper management. In this paper, we examine socio-economic, institutional and exogenous factors affecting household participation in the ...

Assessing the impact of property size on residential water use for selected neighbourhoods in Lilongwe, Malawi
Malawi has one of the highest urbanisation rates in Africa, with an urban housing approach that favours large residential plot sizes. The impact of plot size on residential water use was evaluated by examining water use records, obtained for the period between January 2009 and December 2014, for formal residential properties in the city of Lilongwe. Water use increased with plot size in line ...

The Challenge of Reducing Maynilad`s Non-Revenue Water
Non-revenue water (NRW), poses a very big challenge to many water utilities today. Reducing if not totally eliminating non-revenue water remains the primary concern not only in the Philippines and the Asian region but also world-wide, especially in these times where sources of drinking water supply is rapidly declining. Better and more efficient water supply management is needed to optimize ...

Sustainability assessment of the impact of the Marina Bay development on Singapore: application of the index of sustainable functionality
The index of sustainable functionality (ISF) was applied to assess the impact of the Marina Bay development project on the sustainability of Singapore. The development project has three aims: water supply, flood control and lifestyle attraction; construction for the various stages began in 2005, with scheduled completion end of 2009. The period of study was 2001?2007, before and during ...

An evaluation model for measuring customer satisfaction levels in a water supply domain: case study – water supply in Hamedan
Customer satisfaction is an important goal in total quality management. In order to meet this goal, it is necessary to use an evaluation model to measure customer satisfaction. This paper proposes an evaluation model for measuring the customer satisfaction level in a water supply domain. Some important criteria such as water quality, water quantity, responsibility of the company, etc. are ...

Measuring willingness to pay for improved urban water supply in Offa City, Kwara State, Nigeria
This paper is a study on financial sustainability of water supply service to the city of Offa, in Kwara State, Nigeria. The value consumers place on water supply and the willingness-to-pay (WTP) for improved service and the factors that influence their preferences were determined using an econometric model. The WTP was estimated using a double-bounded dichotomous model and the mean WTP was found ...

Classification of groundwater chemistry in Shimabara, using self-organizing maps
Shimabara City in Nagasaki Prefecture, Japan, is located on a volcanic peninsula that has abundant groundwater. Almost all public water supplies use groundwater in this region. For this reason, understanding groundwater characteristics is a pre-requisite for proper water supply management. Thus, we investigated the groundwater chemistry characteristics in Shimabara by use of self-organizing ...

Major urban water and wastewater systems in Minoan Crete, Greece
During the Minoan era a number of remarkable developments occurred on the Greek island of Crete which have been widely recognized. However, one of the salient characteristics was the architectural and hydraulic function of its water supply, sewerage, and drainage systems in the Minoan palaces, cities, and other settlements. It might be inferred, therefore, that Minoan master craftsmen in Bronze ...
