Changes are proposed to improve urban water supply systems around the globe. Improvement in service delivery mechanisms, institutional efficiency, financial viability and acceptance by users are the key criteria for initiating and sustaining a change. To improve the situation of water supply in Karachi, Pakistan, advised by the World Bank, a private sector participation (PSP) strategy was formed during the 1990s. The strategy aimed to promote a gradual increase of PSP in water and sanitation services. The proposed project faced strong resistance from stakeholders, mainly civil society, leading to its suspension. Efforts are being made to revive the PSP and to make it acceptable to the stakeholders concerned. The paper documents and analyses the stakeholders response to the anticipated PSP process and the possible social and economic impacts. The study makes a contribution in the areas of participation and consensus building in the context of PSP. Willingness to negotiate continuously and even consideration of possible alternatives based on the changing situations are the key to any way forward for sustainable improvements.

Abstract A large part of operating costs in urban water supply networks is usually due to energy use, mostly in the form of electricity consumption. There is growing pressure to reduce energy use to help save operational costs and reduce carbon emissions. However, in practice, reducing these costs has proved to be challenging because of the complexity of the systems. Indeed, many water utilities have concluded that they cannot practically achieve further energy savings in the operation of their water supply systems. This study shows how a hybrid linear and multi-objective optimization approach can be used to identify key energy consumption elements in a water supply system, and then evaluate the amount of investment needed to achieve significant operational gains at those points in the supply network. In application to the water supply system for the city of London, the method has shown that up to 18% savings in daily energy consumption are achievable. The optimal results are sensitive to discount rate and the financial value placed on greenhouse gas emissions. Valuation of greenhouse gas emissions is necessary to incentivise high levels of energy efficiency. The methodology can be used to inform planning and investment decisions, with specific focus on reducing energy consumption, for existing urban water supply systems.
