The shadow return on capital in 75 small municipal water systems is estimated using a gamma frontier variable cost function. The estimated Social Cost of capital exceeds the shadow return by an average ratio of 4.37:1, with a median capital stock inefficiency of $70, 500 per year per system owing to overinvestment in public water supply capital. In addition, actual production costs exceed minim...

Measuring sensitivity of hydraulic structures is considered as an approach for evaluation of water projects performance, due to lower distribution efficiency in Irrigation and Drainage project schemes. Sensitivity analysis approach for irrigation structures is one of flow analysis methods which are developed in recent years in order to measure the behavior of flow in hydraulic structures in an ...

Water supply is a core service on which civilised society depends. It involves considerable energy consumption and, as a result, CO2 emissions (in water treatment, pumping and monitoring) and economic costs. Treated water is most commonly supplied from a central storage reservoir by gravity throughout a catchment and this water must be supplied within satisfactory pressure bands. Where the pres...

An essential challenge for many developing countries is improvement of water supply system to ensure urban water supply safety and reliability. Penalty, subsidy and water price increase are often considered as the main incentive measures for improving urban water supply system. However, the implementation of these policies is confronting some uncertainties because of the conflicts of involved a...

In response to the declining quality and quantity of water resources on the Eyre Peninsula, South Australian Water developed a Master Plan in consultation with key stakeholders to deliver an economical and environmentally sustainable water supply to the Eyre Peninsula in the short to medium term. Three water supply options were considered in detail: extension of the Morgan-Whyalla pipeline to b...
