TRENDS AND INNOVATIONS IN RAINWATER HARVESTING SYSTEMS IN THE CARIBBEAN REGION

D. MAHARAJ, A. CHADEE, L. SEECHARAN

Abstract


Rainwater harvesting systems are conventional technologies designed to foster water security using sustainable water management practices. The design of these systems is becoming more integrated through technological advancements.

 Even though many studies have been conducted on the design of rainwater harvesting systems, there is limited data about the existing infrastructure of these systems in the Caribbean region. To fill this gap, the objectives of the study are focused on the analysis of the constraints using existing research on the efficacy of such systems and formulated into a questionnaire survey. Responses were obtained from key stakeholders who have been or are actively involved in the construction industry.

 Using the insights from construction professionals the key success factors, challenges, and opportunities for improvement on the implementation of rainwater harvesting system are reduced.

The severity of these critical factors was evaluated, ranked, and categorized using the relative importance index (RII) approach. The top-ranking factors were effectiveness of conserving water resources, the improper installation of the rainwater harvesting system, the utilization of filters and filtration systems and the use of pitched roofs. The lowest ranking factors were public awareness, low quality storage tanks, pumps and distribution systems and flat roofs.

These findings reveal that there is a requirement for the implementation of workshops about the importance of rainwater harvesting systems and appropriate training of personnel which corresponds with the advancement of rainwater harvesting systems. Additionally, adequate consideration should be given by Governments to enact appropriate legislation that can help create a conducive environment for the implementation of the system.
