Rainwater Harvesting
Making every drop count
RAINWATER CATCHMENT
Fully Automated Rainwater Harvest System
The landscaped areas and the nursery at Cala Azul are irrigated with rainwater that has been harvested during the rainy season from the road system and the roofs of the Dragonfly condos at the ridge. This water is directed through underground pipes towards a concrete cistern with a capacity of 600,000 liters (600 m3).
This infrastructure represents a significant investment on the sustainability approach of Cala Azul on a regional basis, as it reduces the demand for a more expensive water to produce and deliver by the city, especially in times of drought.
Before the rainwater is finally stored at this collection tank, it goes through a pre-treatment system consisting of three chambers in which sedimentation occurs so that the rainwater enters with less turbidity and very small particles if any.
The harvested waters are pumped to seven 10,000-liter tanks at the south point, and from there, it is distributed by gravity through the irrigation network.
This pumping system has a liquid chlorine dosing mechanism to improve its quality. Even though this water is solely for outdoor applications, chlorine is added to prevent the growth of harmful bacteria and other microorganisms.
WELL WATER
Renewable Source of Life
One hundred feet underground, water from a certified well is pumped to refill the irrigation cistern when the harvested rainwater has been used. This water supply is dedicated to irrigation and to nurture the recirculating stream integral to the nature trail that branches down towards the oceanfront following the contours of the natural ravines inherent to Cala Azul’s topography.
Embracing rocks and filling a series of ponds on its downhill flow, this water becomes available for the wildlife inhabiting or traveling through the core of the tropical dry forest corridor that is being restored and protected by the Community developed at Cala Azul.
POTABLE WATER SYSTEM
Fully Automated Potable Water System
The potable water coming from the city of San Juan del Sur is received in a 160,000-liter (160 m3) cistern designed as a fully automated pumping station from which a collection of ten ten-thousand-liter tanks (100 m3) is filled at the highest elevations of both the north and south points of Cala Azul.
The water stored on the hills is distributed on demand by gravity throughout the community. The installed capacity can be scaled up as necessary and is exclusively dedicated to providing with the precious liquid to each residence and the amenities at your service.
