Benefits of Rainwater Harvesting in Caribbean and Mediterranean

GWP Caribbean (GWP-C) and GWP Mediterranean (GWP Med) are building awareness on the importance of water conservation by implementing rainwater harvesting techniques. With islands surrounded by salt water, the rainwater harvesting model is critical for access to fresh water in both regions.

From March 4-9, 2013, GWP-C participated in a national Community Science Week in Trinidad. The event, which took place in the rural community of Toco, is an initiative of GWP-C’s partner, the National Institute of Higher Education Research Science and Technology (NIHERST).

Rainwater Harvesting Model

Through its participation in the Science Week, GWP-C used its Rainwater Harvesting (RWH) model to engage over 1000 students; more than 50 teachers; and members of the general public in the benefits of RWH and water conservation. GWP-C gave a practical demonstration of how an actual RWH system works. Water education packages were specially prepared for teachers which contained various water conservation activities that could be used in the classroom at the primary and secondary level. The packages also contained background information on GWP-C, the development of its RWH model, and associated online ToolBox.

Video of Rainwater Harvesting System

GWP-Med has released a video of the rainwater harvesting system installed in 2011 on the Greek island of Sikinos, which is a flagship application of the programme. The system collects storm water running off from the two settlements on the island through a drainage system and directs it to a 400 cubic meter reservoir. The water collected is available to all residents and is used for watering their animals, bees, and orchards, thus supporting the local economy. 
One year after the installation, the Mayor of Sikinos, Mr. Yannis Syrigos, reported the significant contribution to the local water security of this small island (273 permanent residents). The RWH system and a small desalination unit put in operation last year, allowed the island to cover their water needs for the first time in many years, avoiding water transfer by tankers, which is a common, yet costly and unreliable practice for the water scarce islands. Watch video with Mayor Sikinos.
