Most of the water has been captured in the rivers of Israel and they have turned into dry river-beds which deliver only sporadic winter floods. In a semi-arid country where literally every drop of water is used, reclaimed wastewater is the most feasible water source for river recovery. Two topics are addressed in this paper: water quality management in rivers where most of the flowing water is treated wastewater, and the allocations of reclaimed wastewater required for the recovery of rivers and streams. Water quality management must consider that the main source of water to the river has a pollution loading which reduces its capability to absorb other pollution impacts. The allocation of treated wastewater for the revival of rivers may not affect negatively the water balance of the region; it may eventually improve it. An upstream bruto allocation of 122 MCM/year of wastewater for the recovery of 14 rivers in Israel may favor downstream reuse of this wastewater, resulting in a small neto allocation and in an increase of the water resources available to the country. The discharge of effluents upstream to revive the river followed by their re-capture downstream for irrigation, implies a further stage in the intensification of water reuse.

Water quality standards set in the past have not helped resource managers in the decisions that they face in seeking sustainable development. Resource managers are looking for meaningful information on water quality so as to evaluate the resource, set priorities for action, and to monitor progress. Resource managers need to know how water quality affects, and is affected by, catchment uses and activities. Examples of three wild and scenic rivers, the Nymboida, Murrumbidgee, and Hawkesbury/Nepean River systems, demonstrate how a ‘Total Catchment Management' approach to resource use and resource protection has advantages for water quality management.

The Gulf Coast Waste Disposal Authority is a regional public agency created by the State of Texas to design and implement water quality management systems in three counties surrounding Galveston Bay. This article will outline the water quality management strategy employed by the Authority for a highly industrialized and populated region. Regional treatment and public and private sector cooperation will be presented as a management objective for muncipal and industrial waste disposal. A description of the background and operations of the Authority will be included along with examples of joint or combined wastewater treatment. The pressing problem of hazardous waste management in Texas will be discussed. The Authority's experiences with facility siting and public reaction will be summarized and a new approach to help resolve these issues will be presented. The article will conclude with some thoughts on strategic planning for public managers.

This paper examines the administrative and legal structure of the wastewater sector in Turkey, identifying its shortcomings and their causes, and suggests solutions. The study begins by outlining the existing administrative and legal structure, then focusing on the areas where difficulties are faced and seeking solutions to them. Those administrative and legal facets which have produced improvements and/or function effectively have been analysed so as to provide examples for other areas. When examining the sector it was observed that problems common to every area are the failure to adequately define powers and responsibilities, the lack of coordination between sectoral organisations, and the fact that attention is generally concentrated on routine matters of secondary importance. The fact that numerous organisations share powers in the same area causes confusion. Plurality also creates difficulties where enforcement is concerned. The existence of more than one set of regulations relating to the same area gives rise to loopholes. At the same time, unrealistic, and hence unenforceable standards undermine the effectiveness of sanctions. It has been concluded that a single organisation should be invested with the legal powers to lay down the principles of water management, that environmental courts should be set up to enforce legislation by means of sanctions; and that for this purpose existing legislation should be reexamined and revised as necessary and/or brought up to date.
