A publicly accessible urban beach entertainment complex is disclosed, with a man-made tropical, pristine-clear lagoon as the centerpiece of the complex, with surrounding entertainment, educational, sports, and commercial facilities, the complex having controlled public access and providing the look and feel of a tropical beach with clear waters and sandy beaches. In addition a method for efficiently utilizing facilities and land that are vacant, underutilized, have limited uses, or that are contiguous to or nearby recreational, educational, sports, or commercial venues is disclosed. The method providing a publicly accessible urban beach entertainment complex with a centerpiece man-made tropical-style pristine-clear lagoon. The method allows for generating revenue and increasing efficiency by pairing vacant sites, underutilized sites, limited use land, or sites that are contiguous to entertainment, educational, sports, and/or commercial venues with urban beach entertainment complexes. The complex preferably has a controlled public access, thereby allowing entrance upon payment of a fee.

A system for limiting the flow from a dispensing valve when a dispensing cartridge is replaced with the system including a dispenser cartridge with a cam and a water socket with a flow limiter therein that is activeable in response to the position of the dispenser cartridge in the dispensing valve and operable in response to an upstream fluid pressure in the dispensing valve.

A multi-stage floatation dispenser for carrying a ballast, which may be a non-water consumable dispersant and at least one water consumable dispersant wherein the weight of the water consumable dispersant decreases as the water consumable dispersant is consumed with the weight of water consumable dispersant and the non-water consumable coordinated with the flotation capacity of a flotation dispenser to provide for either a two stage or a three stage dispensing mode.

A two-part dispensing device for a pool having a dispensing saddle with a static port therein for continual delivery of a first dispersant and a hold for floatingly supporting itself and an exchangeable dispensing pod therein with the dispensing pod having a dynamic port and a static port for a continual delivery of a dispersant wherein the static port delivery of a dispersant maintains the pool at a safe level when there is no human bather load on the pool and the condition of the disperant in the dispensing pod can be determined by the orientation of the dispensing saddle and the dispensing pod in the pool.

A managed water system can include a first body of water contained in a vessel. The managed water system can also include at least one sensor device that measures at least one parameter associated with the first body of water. The managed water system can further include a circulation system that circulates the body of water relative to the vessel. The managed water system can also include a controller communicably coupled to the at least one sensor device and the circulation system. The controller can control the circulation system, and receive measurements of the at least one parameter made by the at least one sensor device. The controller can also evaluate the measurements using multiple algorithms, and communicate a result of evaluating the measurements.

A retrofit assembly for a chlorinator has a cylindrical disk portion having a lower region for insertion into a cylindrical opening of a chlorinator cylinder, a groove for receipt of a first O-ring and a flange at the top to abut the cylindrical opening, and an upper cylindrical member attached to the lower region having exterior threads thereon, a central bore passing through the cylindrical disk portion for passage of chlorine tablets into the chlorinator cylinder, a cylindrical collar with threads for engagement with threads on the chlorinator cylinder, the collar configured to fit over the lower region of the cylindrical disk portion, and a cap having a cylindrical section with internal threads for engagement with the exterior threads of the upper cylindrical member to cover the central bore of the upper cylindrical member, wherein a recess formed in the cap has a bottom for receipt of a second O-ring.

Constructive method and operational process for creation of artificial beaches, suitable for bathing, around plots of land, more precisely, constructive method and operational process for creation of artificial beaches, allowing implementation of watercourses forming isles and/or peninsulas, that contains lots of condominium and/or subdivision, with formation of artificial beaches in perimeter of lots composing condominium and/or subdivision, watercourses are appropriate for contemplation and bathing by condominium members and/or owners of subdivision.

A non-dissolvable immersible dispensing puck in the shape of a dissolvable halogen puck when the dissolvable halogen puck is in an undissolved state with the non-dissolvable immersible dispensing puck physically interchangeable with a dissolvable halogen puck when placed in a dispenser for normally holding only a set of halogen pucks to enable a single dispersant dispenser to be converted to a dual dispersant dispenser without changing the structure of the single dispersant dispenser by placing a dispenser within a dispenser wherein only one of the dispensers may be provided with adjustable water ports.
