This part of the Sustainable Sanitation and Water Management Toolbox is designed as a tutorial to help you in getting an overview of your area in terms of water and sanitation and to help you identify the most pressing problems. It allows you to find specific problems, while keeping in mind the whole picture, i.e., the whole water and nutrient cycle, including its relations to sanitation and agriculture.
This section should allow you to get an overview of your local water and nutrient cycle. It will help you to identify root causes, and how problems are linked, thus giving you and a deeper understanding of the interrelationships between the water resources management, sanitation and agriculture in your specific locality.
Getting a common understanding of your sanitation and water situation/problem: After you got a first understanding of the situation on your own, you need to redo the exercise in a workshop together with local stakeholders. This is crucial to get a common understanding of a problem right at the outset and to avoid future misunderstandings (see also exploring).
Get to know where you will find further information on your issue in the toolbox: Going through this tutorial will get a better understanding of where you will find what type of approaches, tools or technologies and which are most useful to you.
Understand how the toolbox works for you: If you are using this toolbox for the first time, this tutorial is the best way to get a quick, but quite comprehensive first overview of your local water and sanitation situation and shows you how the toolbox could help you.
The graph show the general system approach of the Sustainable Sanitation and Water Management Toolbox. It is a simplified and idealised version of the water and nutrient loop that puts humans at the centre. Water coming from water sources is purified, distributed and used in agriculture, households and industry. By using water for these different purposes, nutrients are introduced into the water cycle (e.g. through wastewater, but also in runoff in agricultural systems, etc.). Wastewater, in order to be treated, is collected. The treated wastewater is reused or used to recharge water sources. Nutrients are reused beneficially to produce food or animal feed, thereby not polluting aquatic ecosystems. In this way, both the water and the nutrient loop are closed.
Now, your system would probably look different (if not, you would not need this toolbox). To help you to get an idea where to start, go through this tutorial step by step. To get a first overview, it should be sufficient to carry out this exercise at your desk or at home, using your local knowledge, and discussing it with your work colleagues or friends. In a second step, you can do it together with stakeholders and experts.
To help you carry out this analysis, we have created the City of Unsustainaville. As the name says, not everything is running as nicely and smoothly in Unsustainaville as in the picture above. There are many problems - some of which you may encounter in your own place as well. This may help you to detect your own problems. For every step, you will find a picture of Unsustainaville, where the current steps and problems are highlighted.
