Reuse of oil and gas produced water in south-eastern New Mexico: resource assessment,treatment processes,and policy

The Permian Basin of south-eastern New Mexico in the United States exemplifies the combination of rapidly expanding oil and gas production with freshwater shortages and aquifer stress. Reuse of saline produced water can provide a stable supply of water for drilling, fracturing and completion and minimize consumptive use of freshwater. We discuss water withdrawals and use by the oil and gas industry in this region, processes for reuse and recycling of produced water in place of freshwater, and operational and policy changes to help improve maximal use of all available water resources in this arid region.     

Is water scarcity a constraint to feeding Asia's growing population?

Growing population and wealth, as measured by per capita GDP, are predicted to put water resources and food production in Asia under increasing pressure over the next few decades. Critical factors include the increasing demand for animal proteins in diets and the growing need for energy. Climate change impacts may further reduce available water resources because of greater evaporation losses in some areas and storms and floods in others. If we are to overcome these significant constraints on food production, we must turn to strategies that are focused around sustainable intensification of agriculture. These include modernization of old irrigation schemes to increase water productivity, innovative concepts that capture and store flood runoff for use in agriculture, much more recycling and reuse of urban wastewater, and other efficiency-improvement techniques. However, these will not happen in a policy vacuum, and it is argued that reforms are needed in water policy, water training and water management institutions across Asia.     

Towards sustainability in water recycling.

Those like us who believe in and spread the gospel of planned wastewater reclamation and reuse usually emphasize that this is a step towards sustainability in water resource management, but this is something that is very seldom analyzed. This paper discusses, from a critical point of view, issues such as goals in water reuse and influence on water demands, ecological analysis of the cycle of the main pollutants, health aspects and treatment requirements, energy consumption and measurable environmental benefits, in order to provide a set of criteria to assess sustainability in water recycling projects and to decrease the impact of the cultural water cycle on the environment.

Application of Islamic Legal Principles for Advanced Water Management

Abstract

Saudi Arabia experienced extensive and rapid developments in all sectors during the last two decades with a rapid and vast increase in water demand. The country follows the sacred principles of the Muslim law “Shari'a,” where water is considered the common entitlement of all Muslims. In the last decades, however, the traditional methods for satisfying the limited water needs have been modified in accordance with Islamic laws to meet the rise in water demand and organize water management issues. Legislation and institutions, new water pricing policies, demand reduction techniques, and regulations for well drilling have been introduced. Support of cultivation of some crops has been modified to minimize irrigation water use, and modern irrigation techniques have been practiced to reduce water losses and demand. The Council of Muslim Leading Scholars has given pioneering examples of the flexibility of Islam by issuing a special Fatwa to regulate the reuse of treated effluents for different purposes. This has promoted wastewater recycling by the public. The Islamic principles used in Saudi Arabia have helped to improve water demand management, and the gained experience can benefit other countries.
