Global and local water-related challenges are becoming increasingly severe due to climate change, population growth, industrialization and urbanization. Flooding is the most disastrous type of local challenge and causes significant problems in human livelihood. A particularly difficult situation occurs when the amount of water to be treated exceeds the capacity of the unit. Then untreated water needs to be led directly to the environment.

The objective of the study is to naturally infiltrate 150 m3 of treated wastewater into the subsoil and analyse its behaviour and reactions with the porous aquifer and when combined with native water. For this purpose, a structure was built to capture the volume to be infiltrated and several observation and monitoring wells to observe the variations in the static levels of wells and 82 samples will be taken for physic-chemical characteristics of water.

Water & Nutrient reuse in irrigation: Robust solutions in Western Europe

The treatment of wastewater with a view to recover both the water & the nutrients has to be favored for a resource efficient strategy, in all countries including European countries. Braunschweig Water Services (BS) have never given up the idea of reusing wastewater in field irrigation, gradually improving the technical settings over a period of more than 50 years. To ensure the quality of the disposed water as well as the sludge, BS have enforced discharge control and requirements for pre-treatment of industrial wastewater: these measures results in the division by a factor of 6 of metallic compounds in sludge and water, thus in compliance with parametric values imposed for soil protection.

Large-scale irrigation projects can bring prosperity to an area but less desirable changes can also occur as a result of increased intensity of land and water use. One important change in the hydrological regime is that of an alteration or degradation in quality that takes place as water is used and re-used within the hydrological basin. In addition, wastewater generated by agricultural and urban sources can degrade water quality and must be considered when developing a river basin management plan.

This plan, the Gaza comparative study of water supply options (CSO-G) differs in both its timing and its overall approach.  It represents the first component of an envisaged emergency response to the problems in the water sector in Gaza, and provides proposals for an overall strategy to address – and hopefully resolve – the current problems.

The Sustainable Sanitation and Water Management (SSWM) Toolbox is an integrated tool for capacity development linking water management, sanitation and agriculture at the local level.The SSWM Toolbox recognizes, that single sector approaches are not going to solve the global water and sanitation crisis. It considers the whole water and nutrient cycle from source to sea and back in an integrated, holistic approach. Focusing on the human influence on the water cycle, the Toolbox helps in finding an answer to the following questions: “How can I optimize my local water management and sanitation system and make it more sustainable?”; “With what kind of processes, measures and tools can I plan and implement my sustainable sanitation and water project?”

WAJ has been contracting with farmers to provide them with reclaimed water for agricultural irrigation. In 2009, a total of about 760 ha is irrigated with reclaimed water under contracts with WAJ. It is worth noting that fodder crop irrigation is the dominant application for all other water reuse schemes in Jordan, with a few exception of irrigating trees such as date palm and olive.  In an effort to integrate reclaimed water resources in national water planning, the government of Jordan, with support from the US Agency for International Development (USAID), has been for the past ten years implementing several projects for direct water reuse activities. Wadi Mousa Water Reuse Pilot Project is one of these projects that seek to demonstrate that reclaimed water reuse can be reliable, commercially viable, socially acceptable, environmentally sustainable and safe.
