By optimizing the use of water in the field detailed or allocated for the  

Green development. This could be done in various ways by ensuring that drains are constructed and they are all linked without any leaving or linking out from the area concerned.To avoid evaporation of water these 'canals' will be covered with materials that will prevent surface evaporation. Alternatively, a network of plastic pipes will be used in the canals spread over the field.

first of all your statement "I need your brainstorming ideas" is very interesting and brainstorming.

Green development is a real estate development concept that carefully considers social and environmental impacts of development. It is defined by three sub-categories: environmental responsiveness, resource efficiency, and community and cultural sensitivity. some interesting links related to your topic is linked below. Hope you find it helpful.

Is not it rather straightforward that responsible use of water as a resource falls under the category of resource efficiency, which is one of the indicators of sustainable development globally according to the UN sustainable development goals (http://www.un.org/sustainabledevelopment/sustainable-development-goals/) and at least in EU (http://ec.europa.eu/environment/resource_efficiency/about/roadmap/index_en.htm)?... Further ideas might originate from discussion on the water footprint and international standards being developed.

Thank you all
