Abstract: A publicly accessible urban beach entertainment complex for bringing an idyllic beach life to 
urban locations in a cost-efficient and sustainable manner, in order to transform the retail 
market, event centers and arenas, cultural facilities, stadiums, golf courses, zoos, university 
campuses, speed tracks, horse race tracks, Olympic venues, and many other recreational, 
educational, sports, and/or commercial venues, the complex comprising: 
a) a centerpiece lagoon, the lagoon having a bottom, a perimeter including curved 
shapes and round corners to resemble a natural water body, and a minimum surface 
area of 10,000 m2 , the lagoon comprising: 
i) at least one bathing zone comprising a zero-entry edge at the perimeter of the 
lagoon, the zero-entry edge having a slope between 5% and 30%, and a localized 
disinfection system adapted to provide an increased chemical concentration in 
the bathing zone; 
ii) at least one water sports zone providing a water depth of at least 1.8 meters at 
its deepest point, and having a bottom at least 80% of which is constructed with 
a flexible, plastic material comprising polyvinyl chloride, polyethylene, rubber, 
or polypropylene, 
b) at least one sand beach area and a rest area surrounding the perimeter of the lagoon, 
wherein the at least one sand beach area comprises sand having a color similar or 
in the range of the following colors according to the RAL color scale: RAL 9001, 
RAL 9002, RAL 9003, RAL 9010, RAL 9016, RAL 9018, RAL 1001, RAL 1014, 
or RAL 1004, whereby the at least one sand beach area resembles a tropical beach, 
and wherein the at least one sand beach area and rest area have a surface area of at 
least 2,500 m2 to allow significant use of such area for different activities such as 
concerts, plays, screenings, and sports, among other activities and events; 
c) a water supply system operatively connected to a water supply for providing filling 
and make-up water to the lagoon, the make-up water having iron and manganese 
concentrations of up to 2 ppm and turbidity of up to 8 NTU; 
d) a water treatment system configured to: 
i) collect water and storing such water in the lagoon having a bottom designed to 
be thoroughly cleaned by a mobile suction means;
ii) during a 7 day interval, treating the water in the lagoon by periodically adding 
a disinfectant agent to said water to establish an ORP of at least 500 mV for a 
period of time dependent on the temperature of the water being treated; 
iii) activate the operation of the mobile suction means to suction a portion of said 
water containing settled solids to prevent the thickness of settled material from 
exceeding 3 mm, and 
iv) filter the portion of water suctioned by the mobile suction means and returning 
the filtered water to the lagoon, and 
whereby the water in the lagoon has a minimum vertical transparency of 1.2 meters 
and presents a less noticeable smell in its majority relative to many conventional 
pools containing water having a chlorine level of 1 ppm, and wherein the water 
treatment system uses at least 50% less electricity compared to electricity consumed 
by a conventional swimming pool centralized filtration system, wherein the filtration 
capacity and filtration water volume is at least 50% lower than for a conventional 
swimming pool filtration system that is operated to filter the complete water volume 
4 times per day, 
e) a physical barrier surrounding at least a portion of the urban beach entertainment 
complex, the barrier being arranged and configured to limit individual access to the 
complex or its centerpiece lagoon; 
f) an access control system located in at least one portion of the physical barrier, and 
being arranged and configured to selectively permit entry of individuals into at least 
a portion of the complex, and 
g) at least one ancillary facility located within the complex in order to allow different 
events and activities to be held within the complex and allow massive public use, the 
at least one ancillary facility being selected from a commercial facility, a recreational 
facility, an educational facility, a cultural facility, a residential facility, and a sports 
facility; 
wherein the complex is located in a site having a minimum total surface of 16,000 m2 that has 
a surrounding population of 200,000 people within a 30-mile radius with road connections and 
access, the site being selected from vacant land, underutilized sites, or limited use land, thereby 
transforming the lifestyle of people around the world by targeting the nearby surrounding 
population connected by road access.
