Assessment of subsurface flow constructed wetland systems as secondary wastewater treatment for reuse in irrigation

Abstract
Reclaimed water reuse for indirect consumption purposes such as irrigation resolves two key issues in integrated water management - high freshwater abstraction and water source contamination. The study aimed at identifying the applicability and social acceptability of dairy farm wastewater reuse for irrigation using effluent quality and removal efficiency analysis and a perception-based (senses of sight and smell) Likert scale questionnaire. Effluent samples from the different subsurface flow constructed wetland systems were collected and analyzed. Samples were sent to 200 respondents together with a questionnaire to facilitate blind and learned perceptions analysis. From the laboratory test results, the two-phase systems were more efficient in contaminant removal. Based on the ANOVA and Duncan's Multi Range Test, acceptability level of the hybrid and the vertical in series subsurface flow constructed wetland systems are at 3.815 and 3.6225 out of 5.00, respectively. After an array of socio-economic factors were considered, results of the study showed wastewater reclamation and reuse is acceptable and that the local community surrounding the dairy farm is more willing to use reclaimed wastewater to irrigate their crops - ornamentals, vegetables and fruit bearing trees - after going through the two-phase subsurface flow constructed wetland systems than the one-phase systems.
