Screening: Strainers and leaf screens located in the gutters and downspouts will
be used to prevent the debris, like leaves, from entering the reservoir tank.
Settling. Sedimentation within the tank is necessary to settle out any potential
particulate matter and solids.
Filtering. In-line multi cartridge systems with activated charcoal will be used to
remove potential contaminants either at the pump tank or tap.
Disinfecting. The use of chemical treatment (chlorine, iodine), ultraviolet light,
and/or ozonation will be used to kill the microorganism usually found in the tank.
4.5.2 Secondary Source Description
It is estimated that a 10,000 gallons a day water desalinization plant will be used to
provide potable water to the amenities and be used as a back up source to drinking water.
The Desalinization plant or R.O. plant as it is normally referred to will get its water from
a well that will be dug on the project site. Figure 4.3 show a typical well cross section.
The plant will consist of a set of membrane filters that will be cleaned regularly. Water
generated by this process will be sent to a 15,000 gallons tank where it will be treated and
piped via water transmission lines to the different areas as required by the development.
The brine waste produced won’t be of concern as there are two disposal options that are
presently being contemplated by the project developer (figure 4.4). The first option
includes the injection of the brine into a deep well, dug some distance away in the
property. This brine, which comprises of most salt precipitates, would be safely contained
in the well, where it would diffuse eventually. The other option includes the use of
diffusers to safely diffuse the brine into the lagoon. Water quality data in the lagoon
indicated elevated levels of salinity. This elevated level, can possible be attributed to the
shallowness of the lagoons and water exchange rate. Discharging the brine solution into
the lagoon would not significantly affect the biological diversity.
