Technical Guidelines for Greywater Reuse
The reuse of greywater requires technical rigor. NBR 16783 It establishes the parameters for non-potable use. Therefore, the design must separate bath and sink water from black water. Furthermore, the filtration system must ensure the removal of suspended solids. Thus, the system's efficiency depends directly on correct hydraulic sizing.
Design Sizing and Loads
The load calculation considers the number of users and daily consumption. For example, in a high-end residence close to... Beto Carrero World theme park, The irrigation demand must be mapped accurately. Below, we present a reference table for typical loads:
| Source | Estimated Flow Rate (L/day/person) | Organic Load (BOD) |
|---|---|---|
| Showers | 50 | Low |
| Washbasins | 10 | Low |
| Tanks | 15 | Average |
Therefore, the treatment system must process this volume daily. However, it is essential to provide equalization tanks to avoid flow peaks. Consequently, the sizing of the biological filters ensures the stability of the final effluent.
Treatment and Safety Processes
Basic treatment includes primary sedimentation and filtration. Furthermore, final disinfection is mandatory to avoid health risks. However, any cross-connection with the potable water network must be avoided. Therefore, physical separation is the main safety barrier required by current regulations.
Integration with WGB Infrastructure
Modern engineering prioritizes circular systems. Therefore, integrating greywater reuse reduces the operational costs of buildings. Furthermore, its use in toilet flushing and irrigation drastically reduces consumption from the public water supply. In this way, our technical team ensures regulatory compliance and resource optimization. Designing with WGB means investing in long-term sustainability. To optimize your water resources and raise the standard of your [building/project/etc.]. work in Penha, Our team is ready to integrate efficient solutions into your project.
