Geometric freshwater sanitary areas are created within large water bodies without the use of physical barriers to separate the area. A coordinated reference system (CRS) is used for mapping the defined geometric freshwater area in terms of its position; the definition of directional vectors (DVs) for the introduction of freshwater into the geometric freshwater area through inlet elements to achieve a minimum renewal rate of such geometric freshwater area; the application of a Comparative Water Renewal Index (CWRI); and the application of a Homogeneity Index (HI) based on the mixing conditions of the geometric freshwater area and its required homogenous conditions. Utilizing the processes together generate geometric freshwater sanitary areas that are suitable for bathing (direct contact purposes).

A low-cost structure is for the containment of high clarity water. The structure provides for the purification of water that is used for direct contact recreational purposes. The structure utilizes microleakage and a dual frequency skimmer system.

A sustainable heat transfer system that includes a digital processing facility and a recreational man-made swimming lagoon that provides cooling for such facility, the system being configured for contributing to environmental sustainability and community benefits, comprising a man-made swimming lagoon, a High Temperature Water Treatment System, and a waste heat transfer mechanism.

A dual method and system for eliminating suspended particles from artificial bodies of water possessing a minimum surface area of 10,000 m 2 is provided. A permanent sub-standard centralized filtration flow is utilized together with a Chromo-Turbidity Index (CTI) below about 19. The CTI is maintained by introducing an effective amount of a CTI-Decreasing Agent. Other agents can also be introduced.

A venue transformation and construction method is disclosed that creates a tropical style swimming lagoon at an infield site of a race or activity circuit facility, the infield site being contained within a race or activity circuit perimeter. The transformation includes demolishing at least part of the infield site; excavating material from an area within the infield site; and forming a basin for a large water body having a surface area of at least 3,000 m2. Water containment walls are constructed on a first section and a sloped access area is formed on a second section of the basin for a beach. A barrier is included to control access to the beach. At least one additional recreational facility is constructed around the basin and a connection is provided that connects the outfield of the race or activity circuit with the infield site to allow transit of vehicles and/or people.

A treatment for a large body of water to make the water suitable for recreational purposes is disclosed. A sedimentation zone and a dissipation zone are designated in the water body. A disinfection method based on a CT index and a flocculant composition are utilized in the sedimentation zone to aid in the settling of different microorganisms and/or contaminants. Also, the water in the sedimentation zone is minimally disturbed to facilitate the sedimentation process. A permanent chlorine residual is maintained in the dissipation zone by adding an efficient amount of a chlorine disinfectant such that at least a 0.5 mg/L free chlorine level is maintained in the water volume. Water is injected into the dissipation zone by means of one or more inlet nozzles. Along with natural currents produced by winds and water temperature differences, a water dissipation pattern from within the dissipation zone into the sedimentation zone is generated.

An urban performance venue having a waterfront setting for providing entertainment to an audience is disclosed. The venue includes a performances surface that includes a reference point located substantially in its center. A first spectator area is located closer to the performances surface, is substantially covered with a sandy material, and has an elevation angle not higher than 10° with respect to the performances surface. A second spectator area is located farther from the performances surface, has an elevation angle of at least 30° and extends over at least a 90° reference angle view from the reference point. A man-made clear lagoon extends from a side of the performances surface away from the spectator area, partially surrounds the performances area, and is arranged and configured to resemble a portion of a tropical sea. Wherein the line of sight from a spectator includes views of the performances surface and the lagoon.
