Water saving technology adopted – Rainwater Harvesting
Why they chose to invest
The Greek island of Syros is a dry island with poor annual rainfall. As with Malta, most of its water is provided through reverse-osmosis desalination of seawater, and through groundwater abstraction.
Global Water Partnership’ Mediterranean (GWP-Med) aims to support the sustainable development and management of water resources at all levels in the Mediterranean. GWP-Med teamed up with the Coca-Cola system in Greece and the Municipality of Syros Island to create a case study in one of its parks within the Greek Islands’ Rainwater Harvesting Programme. The aim was to install a cost-effective water catchment system which required little ongoing maintenance, and could be quickly and easily constructed. Collected storm-water was planned to be used for irrigation.
After reviewing the space available for a collection cistern, a decision was taken to excavate an area beneath a football pitch in the park and use modular tanks for storm-water storage. These tanks were chosen as they require no maintenance; construction takes place on site; requires no heavy machinery; and is quick to complete taking only 2-4 days for a 200m3 capacity. An attractive advantage to this choice of storage is that it could be roofed over and the area returned to its original purpose – a football pitch.
How satisfied is the partnership with the technology?
Installation was completed in November 2011. Since then the tanks have collected an estimated 400 m3 of storm-water, enough to drip-irrigate all the parks plants including an additional 300 planted to make the area greener for the local community’s benefit.
The project cost €55,000.
