How does Waterproof work?

WaterProof is a tool that aims to help community and institutional actors to design case studies that help them decide on the most appropriate Nature based Solutions for their city’s climate and water demand conditions.

Although the user can consult the available case studies, the aim is for analysts to have tools to accurately indicate the way in which water is obtained for a city from water intakes located in supply basins, as well as the characteristics of their treatment plants, so that, through soil and climate analysis, it is possible to suggest the most appropriate Nature based Solutions and their respective return on investment.

In the graphic below we explain the major steps that must be taken in the system to obtain results:

a. Configure the water supply intakes from your city:

4. The system will ask for estimated data on the water demand by each catchment.

5. Indicate which processes and technologies are part of your treatment plant. Each technology has its cost function.

6. Define the cost functions for operation and maintenance of the treatment plant. If you don't have them, the system will use default values.

1. Indicate the location of the catchment or catchments that provide water to your city.

2. Indicate the characteristics of your water intake system: types of connection, existence of reservoirs, external entrances, among others.

3. Define the functions that determine how the operation and maintenance costs of the water system. calculated. If you don't have them, the system will use default values

The system will allow you to record all the water intakes and treatment plants that you need in your analysis. The system is then prepared to start the analysis.

b. Set up your case study:

1. Link all the catchments and treatment plants that you want 

2. Configure the objectives and activities that you want to integrate into analysis

3. Create the financial settings

4. Launch the analysis by indicating to the system the climatic conditions that you believe will be present during the course of implementation of your project.

5. Take advantage of the results of the analysis. The system will present you with suggested areas for the implementation of the Nature based Solutions accompanied by indicators and graphs on the Return on Investment

d. Article - WaterProof—A Web-Based System to Provide Rapid ROI Calculation and Early Indication of a Preferred Portfolio of Nature-Based Solutions in Watersheds

Watersheds are being degraded around the world, with dire impacts on water security. Nature-based solutions (NbS) can preserve or restore degraded watersheds, thereby addressing critical water security issues; however, there is a lack of NbS uptake and investment. This is in part due to the complexity and time required to demonstrate an NbS portfolio’s positive return on investment (ROI) for desired water security outcomes. WaterProof is a web-based decision support tool to provide a rapid ROI calculation and early indication of a preferred portfolio of NbS for any watershed in the world using Natural Capital ecosystem service models (InVEST and RiOS). WaterProof is intended to engage stakeholders interested in exploring green infrastructure solutions for local water challenges and for prioritization of locations of possible NbS water security programs. WaterProof version 1.0 is freely available and open-sourced, with clear methodology and metadata, with a user-friendly interface suitable for a wide range of potential audiences.
