persons require 146,000 × 100 = 14,600,000 gallons of water per year. Since a standard 1 m

plastic tank can trap 224 gallons per hour, tugging down of cloud water
by HSEF described above shall require only ten (10) ideal 1 m

insulator tanks to
meet the total water demand for a standard building of 32 m × 31 m with a height
of 30 m.
In Situ Water Treatment
Since the gathered water in the insulated tank is simply the liquid state of cloud
water, it will not require any conventional process of sedimentation, coagulation,
and chlorination to clean the water to make it potable. Just implementation of the
UV application and filtration is required to treat the water to meet the US National
Primary Drinking Water Standard code [6, 52]. It is the most unadorned approach to
treat water by utilizing SODIS framework (SOlar DISinfection), where a simple
chamber is filled with water and exposed to full daylight for a few hours (Fig. 6.8).
Once the water temperature reaches 50 °C with a UV radiation of 320 nm, the activation process will be accelerated rapidly to eliminate all microorganisms which
will be then usable immediately for domestic water supply [15, 52].
This technology is not just an imaginative wellspring of water supply for a building by the usage of electrostatic power to catch the cloud water and treat it in situ by
UV application for domestic use, but indeed it will without a doubt be a novel,
coordinated, and inventive field in science to fulfill the potable water crisis throughout the world.

if the UV radiation of 320 nm of solar light is implemented into the cloud water with a temperature
of only 50 °C, it eliminates all microorganisms immediately
