The ReWaterDesign Key gives you exclusive access to HarmonyBio’s online greywater and rainwater calculator, developed in compliance with UNE-EN 16941 standards.
This tool allows you to estimate the potential for water reuse based on flow rates, occupancy, and building characteristics—offering a professional and technical approach for real-world projects.
After purchasing this product, you will receive a 📋 Project Code (ReWaterDesign Key), which you can use on the platform to generate an Advanced Digital Report tailored to your data.
💡 What’s Included?
-
Detailed simulations and comparative scenarios of consumption, savings, and performance.
-
Automatic analysis with regulatory interpretation according to UNE-EN 16941-1 and UNE-EN 16941-2.
-
Quick review by an engineer to ensure consistency and reliability of results.
-
Personalized recommendations based on the type of installation and project conditions.
-
Digital delivery within a maximum of 48 hours.
🧠 Why Is It Necessary?
For projects with more than 8 occupants (hotels, gyms, residential communities, urban buildings, etc.), consumption patterns and installation conditions differ from those of a single-family home.
While the UNE-EN 16941 standard provides a general framework, it does not address every specific case.
The ReWaterDesign Advanced Digital Report offers a customized perspective, with technical scenarios that reflect real project conditions, serving as a foundation for the design and sizing of the treatment and IoT systems.
