How to Utilize Water Efficiently with Rug Steamer?
Outdated carpet wash systems use a lot of water for cleaning carpets, making their use difficult in commercial settings. Modern rug steam cleaner machines, on the other hand, with their advanced features and efficient water use, are able to eliminate many problems faced by older machines. Low flow technology When flow rates are low, the rug steam cleaner can be considered as water efficient. ...

Can regulation improve the performance of government-controlled water utilities?
This paper provides evidence on whether regulation can improve the performance of government-controlled water utilities. While other studies have examined whether private participation combined with regulation can improve the performance of government-controlled water utilities, there has been little research on whether regulation alone can improve performance.This paper examines five case ...

The most efficient clusters of Brazilian water companies
Usually water utilities provide their services under natural monopoly, with few incentives to become efficient, therefore affecting customers in the form of expensive tariffs. Hence, it is extremely important to find out the sources of inefficiency. The present study aims to identify the most efficient water utility groups in Brazil. For this purpose, a robust non-parametric method was ...

Application of a water balance adapted to intermittent water supply and flat-rate tariffs without customer metering in Tiruvannamalai, India
Establishing the water balance developed by the International Water Association (IWA) is a worldwide applied approach to determine and analyse water losses in water distribution systems (WDS). The water balance covers those parts of a WDS within the responsibility of the water utility. Water losses occurring ‘before’ a customer meter are at the expense of the utility, while water lost or ...

Determining the optimal investment plan for water utilities: the case of Veolia Water Central
Water utilities face difficult choices in how most efficiently to plan for investments that best meet the needs of their customer base. An obvious interest of water utilities is thus to optimise their investment planning to obtain the maximum possible benefits for the costs accrued by the investments. The objective of this article is to demonstrate an approach for a water utility to determine the ...

An exploratory approach for evaluating the energy and personnel share of operation and maintenance costs for water utilities in selected emerging economies of Europe
This study provides an analysis of specific performance indicators for water utilities in four countries, Albania, Hungary, Poland and Romania. The annual operational and staff cost indicators from records of the IBNET database have been analysed. Statistical analysis indicates significant differences between the fraction of energy and labour operational costs among the countries studied. Some ...

Transition of water demand and treatment plant overcapacity: a case study of the Seoul Metropolitan City, Korea
This study deals with the overcapacity problem of water treatment plants in Korea, and mainly discusses status, causes, and engineering options. To this end, we first statistically analyze the recent trend of demand, revealing that the demands of small- and mid-size systems are still increasing while that of large-size systems is now decreasing. Since the existing approach to plan capacity ...

Topic: Benchmarking and Performance Indicators
One of the important ways organizations, evaluate the effectiveness of a process or activity is by defining and using some performance measures. These measures could be quantitative or qualitative but should be clearly defined, easy to use and understand, technically sound, be able to measure trends over time, and be relevant to the users—in this case water utility operational staff and ...

Optimising the water sector market structure in Portugal
This paper investigates the market structure of the water sector in Portugal through the application of distinct methods usually used in the literature (parametric and nonparametric methods). A sample of Portuguese water utilities was used to search for economies of scale and economies of scope in the period 2002–2008. High economies of vertical integration, economies of scale and ...

Performance of Portuguese water utilities: how do ownership, size, diversification and vertical integration relate to efficiency?
This research applies the stochastic frontier analysis benchmarking method to measure the performance of the water sector in Portugal. It estimates a multiproduct translog cost function in order to study the efficiency of the water and sewerage services, using an unbalanced panel comprising 68 Portuguese water utilities for the biennium 2004–2005. The sample is formed by concessionaire companies, ...

Towards a Service Quality Model for Water Utilities
Regulation of water utilities is often achieved through “yard-stick competition”, where the service quality of monopolistic service providers is compared with peer organisations in the same jurisdiction (Braadbaart, 2007; Lin & Berg, 2008). Regulatory models for water utilities focus on measuring business performance through a series of indicators (Braadbaart, 2007; Byatt, 2013; ...
