Table 3.

Summary of three prototypes that resulted from the co-design process implemented in the study area

Prototype	Scale of treatment (beneficiaries)	Investment Costs in USD	Operation & Maintenance requirements	Stakeholder involvement: Municipality	Stakeholder involvement: Neighbours
Horizontal subsurface flow constructed wetland	Household level (1 house)	2500	System works by gravity and natural processes. Cleaning the vegetated surface (carried out by the house owner)	Consult Municipality approved the modification of public space	Empower The owner of the property *Other neighbours were only informed
Bioretention area	Street level (15 houses)	11 000	System works by gravity and natural processes; cleaning and pruning the vegetated surface, removing solid waste from the system’s components	Partner Municipality is committed to maintain the prototype	Consult
Infiltration area	Sub-basin level (approx. 260 houses)	35 000	Involve Closest neighbours *Other neighbours were only informed
