A modular deck drain system comprising a bottom channel and an upper cover. The bottom channel has a pair of opposed side walls and a bottom surface coupled to the side walls. The bottom channel also has a plurality of stabilizing members coupled to and extending from an external surface of the bottom channel, and at least one modular junction node. The upper cover is configured to couple to the bottom channel. The upper cover has two upper walls, each wall having a top end and a bottom end, and the top end of each wall is coupled to an upper lip. A narrow top opening is formed by the upper lips. The upper cover has at least one cutline.

Modular pool comprising a support structure placed around a containment basin for the water and comprises a plurality of metal plates, joined together, which comprise a base for resting on the ground, an upright at least partially above ground, and lateral edges provided with a reinforcement flange. The pool also comprises fixing elements fixed to the base of the metal plates and anchored to the ground, a waterproofing layer placed to coat a bottom and a lateral surface of the containment basin, and a surface finish layer placed to cover the waterproofing layer.

A pool perimeter assembly extending along a portion of a pool perimeter includes a combined gutter assembly having a gutter conduit and a grate supported above the gutter conduit. The combined gutter assembly also has a partition dividing the gutter conduit to form an exhaust air plenum on one side of the partition. A surge tank is fluidly connected to through a modified converter box and a water-air line to the exhaust air plenum. An exhaust fan is connected to the surge tank and generates below atmospheric pressure so that the contaminated air on the pool surface is drawn through the grate and into the exhaust air plenum, through the water-air line, into the surge tank, and of the surge tank through the exhaust fan.

The present specification discloses a pool overflow drain heightener that prevents pool water from draining through the pool overflow drain during normal usage, yet permits draining during an emergency overflow event. The pool overflow drain heightener includes a dam basin having an upper rim that defines a mouth configured to be positioned above the desired water level and above the lowest point of the pool overflow drain, such that the water level can temporarily or permanently rise above the lowest point, yet not drain from the pool. Excessive water levels will still be able drain through the mouth, and out the overflow drain, thereby preventing overflow of the pool.

The present invention relates to a swimming pool structure having at least one edge zone and a water collection, filtering and recirculation circuit, the latter including at least one well zone (WZ) for falling water, at least one filter mounted in the well zone and designed to intercept the water falling into it.

An original drain is removed from a pool gutter by cutting the joint where the drain tube joins the drain pipe. The remainder of the drain pipe is contained in a portion of the original drain tube. The replacement drain tube is inserted and bonded into the interior of the remaining drain pipe. A liquid flow path and reinforced joint are defined by the hopper of the replacement drain, original and replacement drain tubes, and the drain pipe. The top of the hopper of the replacement drain is tilted to about the slope of the gutter.

The subject of the application relates generally to the field of drainage elements, typically drainage channels, and covers thereof, as well as mixtures for production of such covers. Embodiments may include drainage element covers, meeting functional (water permeability, slip resistance, abrasion resistance, hygienic safety, strength, resistance to frost, etc.) as well as aesthetic requirements, and which would be suitable for applications in exteriors as well as interiors, and further propose a mixture for production of such drainage element covers. Functional and aesthetic requirements may be achieved by means of a mixture for producing drainage element covers, comprising aggregate and/or milled glass pulp and binder, and further comprising thixotropic additive.

One aspect of the invention provides a system including: a liquid filter configured for fluidic communication with a fluid repository; a flow sensor in fluidic communication with the liquid filter; a variable-speed pump in fluidic communication with the liquid filter and the flow sensor; and a processor in electronic communication with the flow sensor and the variable-speed pump. The processor is configured to: determine a total volume threshold for a filtration procedure of the fluid repository; identify a set of fluid flow activities performed by the variable-speed pump; determine a remaining volume for completing the filtration procedure by reducing the total volume threshold by a volume of fluid moved by the variable-speed pump during the set of fluid flow activities; and determine, from a set of energy-expenditure factors and the remaining volume, an activation schedule and an activation power output of the variable-speed pump for completing the filtration procedure.

A system for the removal of volatile products resulting from the disinfection of water in a swimming pool, including a main channel arranged at an edge of a swimming pool and to collect overflowing water from the pool, air suction holes distributed along the main channel, the suction holes facing the internal volume of the main channel and being arranged at a height above the free water surface in the main channel, ventilation device configured to generate a suction flow of air from the suction holes. The system includes an air insufflation device arranged in the main channel at a height below the free surface of the water in the main channel, the air insufflation device generating a flow of air to strip the gases dissolved in the water in the main channel, from the liquid phase to the gaseous phase.
