Water Use Efficiency Planning

Water Use Efficiency simply put is using water without waste. Water Use Efficiency goes hand in hand with Water Demand Management. Water Demand Management is the efficient allocation of water to meet growing demand for consumption. Without doubt they both have technical aspects to them. For example Water Use Efficiency is divided into allocative and technical efficiency (according to GWP there are two other divisions- Productive Efficiency and Product Choice Efficiency) and water demand management has its own divisions (Industrial, agricultural, residential, water supplies and so forth). We have gathered resources that will help the user better understand these divisions and how they are taken into consideration when developing a Water Use Efficiency and Water Demand Management strategy. These resources will also show that an important output of these plans is the development of water pricing. These resources have been placed into subsections for your convenience.

Concept of Water Use Efficiency and Water Demand Management
In order to successfully manage and implement an Integrated Water Resource Management, Water Use Efficiency and Water Demand Management are key concepts that need to be seriously looked at. You may find that many countries do not have such strategies or plans in place or are in the process of developing one now. The consequences of years of neglect is failing infrastructure for water resources that will need to addressed as soon as possible for proper water demand management to take place. This is only one example of not having these plans in place. The resources we have for you will explain in more detail the concept of these strategies, why and how they are prepared, the economic tools used (allocative efficiency and cost benefit analysis) and their necessity to IWRM.

Case StudiesThis case study shows the development of a Water Efficiency Plan for the California Region. It demonstrates what is required to develop such a plan and what considerations need to be accounted for before you can start on such an undertaking.
