A Greywater Monitoring Protocol for Off-Grid Greywater Treatment and Reuse Systems

Greywater usage is of great interest in a world where water distress is of a severe concern. The challenges surrounding off-grid greywater monitoring, raised already by previous research from greywater market-leader countries, concern mainly about quality parameters. This research will explore how greywater quality parameters can be utilized as general indicators of treated-effluent water quality and, finally assess the appropriateness of a sensor-to-mobile application for greywater monitoring network for permitting greywater to be used for irrigating cash crops whilst ensuring human and environmental health.

The research will focus on the suitability of an off-grid greywater monitoring for the specific need in rural developing regions. The hydrochemistry aspects of the research will be complemented by findings from the field of Environmental Management, utilizing data from various rural household greywater pilot projects in the West Bank. The research will incorporate stakeholder analysis, market research, capacity building among the community of end-users and environmental risk management to establish whether an off-grid greywater monitoring protocol is both possible and advisable.
