An optimization procedure for the sustainable management of water resources

The sustainable management of water resources requires the identification of procedures to optimize the use and management of resources that are able to deal adequately with the problems of an integrated water service. Taking cue from the classic problem of transport of operations research, this paper proposes a procedure to optimize the allocation of resources for water supply in an area. The transportation problem has been particularized to the case of water resources management considering water intake structures present in a territory as source nodes and utilities in the area as destination nodes. The variables to be determined are the quantity of water resources transferred from each source node to each destination node, in order to achieve a balance between the needs and availability, minimizing the costs of supply consequently necessary. The problem that is obtained, is a constrained non-linear type problem that can be used, for example, to solve local problems of supply, through the redefinition of the distribution system. An application of the model to the province of Croton in southern Italy is shown. The results obtained from the application of the model show the reliability of the methodology in applications similar to that of the case study.

Process Element

Water and poverty interface in many different ways. Sustainable management (i.e. development, allocation and utilization) of water resources is therefore a process-element of sustainable human development. This paper looks into water-poverty interfaces as well as into approaches to, and tools of, managing water in such a manner that water sector activities can contribute to alleviation of poverty. It gives a southern perspective and includes a case study of the evolving water management regime in Bangladesh.

The Difference

Non-revenue water (NRW) is the difference between net water inputs in the distribution system and billed authorized consumption. Water resources are under stress due to growing population and climate change making a shift towards the implementation of non-revenue water reduction strategies in most countries worldwide (Kanakoudis and Muhammetoglu, 2014). It is expected that by 2030, 47 % of the world population will live in regions with severe water stress (González-gómez, García-rubio and Guardiola, 2015). The increase in water demand coupled with Non-Revenue Water (NRW) is causing a challenge in meeting water demands for all competing uses of water; hence the need to assess the management of non-revenue water in Doka district of Kaduna North LGA. In assessing the existing situation and the management strategies to minimize non-revenue water in the Doka district questionnaires and Key Informant Interviews (KII) were administered using purposive sampling. Results show that plumbing materials to fix bursts and leakages which contribute highly to NRW are inadequate to the tune of about 70%. There should be a proactive programme of constantly reviewing the basis for estimation of bills for customers who are currently not metered to improve the accuracy of these estimates while efforts should be made to complete the metering of all customers.
