Living Lab #04 Central Helophyte System Dwarka: Retrofitting i) Issue: This is an opportunity rather than an issue. The barren lands can be used for as open green public spaces with this project.
iii) Project description: The helophyte filters can be implemented along streets, in courtyards as a larger field or in existing waterways. A connection to the separate grey water system of the block or street and the surface water is necessary as well.

ii) Strategy: The helophyte filters are vertical flowing reed fields where grey water can be treated. These reed fields can be easily integrated in the urban fabric as they bring (green) quality. Nevertheless, there is many space needed for the filters (2 m2 per inhabitant). The helophyte filters should be implemented on street or block scale to make integration possible.

iv) Implementation: a) Supporting Policies/ Projects 1. Incentives to the households from the municipality for adapting smarter ways of resource usage. 2. Information through educational institutes & initiatives. b) Conditions / Scenarios for implementation This project can be successful very easily if merged with the greywater separation system. c) Involved Actors and Stakeholders Citizens +private
