From the information in table 4.4, the project will source their water by means of rain
water harvesting. The basic roof catchment system will be augmented by recycling of the
gray water produced by the various facilities. During periods of heavy water use the roof
catchment will be augmented by the small reverse osmosis system.
4.5 Source Supply Description
The total potable water demand for the project will be about 40,070 gallons a day at full
development and operation. This volume will be the initial capital water supply
requirement for the project and this volume is expected to be reduced as recycled and
desalted water is used to supplement the existing demand. The sources will be as follows:
1- Main Source: Potable water for operation will be gotten from rain water
harvesting. Since the project will consist primarily of condos, villas and other
buildings, rain water sequestered from individual roofs will be stored under
buildings in cisterns designed as integral structural elements of the foundation
structure. Each building will have its own rain water cistern along with all the
necessary equipment needed to supply the building with water. The roof of the
buildings will harvest the water where it will be conveyed to the foundation via
gutters and pipes. A small in line filtration system will be installed on each
building to treat the water. Potable water for the water cabanas will be gotten
from the activation of the R.O. plant. Water transmission lines will be laid
underneath the piers and branched off to each cabana.
2- Secondary Source: In case of water shortage due to over consumption, as could be
the case during the dry months, water can be gotten from the activation of the
Water desalinization plant installed in the utility zone and transported to the
desired area. The volume generated by this process will be small to medium and
will be used as a back up source to drinking water, and to supply water to the
pools, spa, kitchen, restaurants and bars. This will also be the primary source for
the construction phases. The RO Unit to be deployed will yield 3,000 gallons/day.
The desalted water will be chlorinated and stored in a 5,000 gallons ground
reservoir.
3- Tertiary Source: The basic roof catchment system will be augmented by recycling
of the gray water produced by the various facilities for such heavy water
consumptive uses as toilet flushing, landscaping and other non-potable use. The
treated (chlorinated) wastewater will be stored in a 10,000 gallons tank and sent to
the different areas to be used as required. For the flushing of toilets a color coded
water transmission line will be facilitating this process. Table 4.6 shows the
volume required by the project to enable this water to be used for the required
purpose.
4- Construction Demand: It is difficult to ascertain the volume of water required for
construction purposes. Moreover, the daily demand required for the construction
workers since they may vary depending on the work load or construction
