P-REC recreational Pools


This Rule is applicable Regulatory in pools containing glasses dedicated to leisure, recreation and bath of youth and adults, especially non-swimmers.

This document has been produced with the purpose of normalizing regulatory aspects of any facility able to practice this activity.

In construction projects or reform of recreational pools should be considered compliance and Autonomous Municipal concerning the pools of collective use affecting them.


Recreational vessels will be included in a pool complex, which is a Useful aquatic facilities for recreation, physical education and training or sporting competition of children, youth and adults.

All glass for recreation must be separated from the remaining for a minimum distance of 5 m.

Are valid for recreation of young people and adults non-swimmers preferably in the area of shallower and swimmers throughout its Area.

Recreational vessels along with their outer bands can be grouped with sports vessels, the pits of jumps, multipurpose vessels and its outer bands forming a single compound. Should be isolated from the splash glasses and teaching. See
regulatory standardsSplashandEducation. Will be protected the scope of prevailing winds that upset users, as well as the proximity of Trees or deciduous plantations which can contaminate vessels. There are No shadows dropped on the glass or diminish that hide solar action.


Recreational vessels can be designed most varied forms, if and when there are no bends, angles and obstacles that hinder the movement of water, clean, the monitoring of the water or may be hazardous to users.

The surface of water may not be less than 200 m2 and in any case your choice will be based on the calculation of needs of the Area served by the pool.See the section of the rules of draft Pools.

Among the many ways that you can give these glasses, a particular case is the rectangular that are selected on the basis of their simplicity of construction and lower cost. The water must have, in this case, identical dimensions some that are checked in the vessels of teaching, sports multipurpose.

Allowed for the possibility that in a same glass designing independent areas, either for recreation, either for the sport of swimming or water-polo, if it is indicated in the right places the change of use and depth. This will be done in both the signs bordillo-rebosadero through alert indicators of the depth, as in the walls and merits of the glass through continuous lines red 0.10 m wide or other physical elements that does not pose any danger to the user.

If you have water slides must be delimited its area of fall so preventing accidents with other bathers. The water slides must be safe so as not to risk of accidents in users, which met the requirements set out in the following rules: UNE IN 1069-1 “ Water slides of more than 2 m in height. Specifications 1: and test methods ” and “ 1069-2 IN Water slides of more than 2 m in height. ” Instructions 2:

If there are platforms and / or bouncy trampolines will have a moat of independent jumps, see the standard NIDE of jumps. If you have height trampolines less than 1 m respect the water, can be placed in the glass if its recreational area is delimited drop so preventing accidents with other users.

The minimum depth of this type of glasses is 1.00 m and maximum will be 1,40m recreation area of non-swimmers and 2,20 m in the swimmers. Where you have water slides or areas of jumps depth in this area will be the appropriate and at least 3 m. When we reach the depth of 1,40 m is indicated in the kerb, walls and merits of the glass as described in the previous paragraph. If there exit platforms for swimming, the minimum depth 1,40 m will (recommended 1.80 m), since 1 m 6 m of the wall point where you put these platforms.

Surface slope of the fund will not exceed 6% and will be as a minimum of 2%, in any of the lines that can rely on him, develops its steepest line perpendicular or parallel to the walls of the glass fronts.


To enable the movement of users around the glass, as well as to separate the water from other areas and gardens in outdoor pools, develop on a glass outer bands, beaches or platforms paved throughout its perimeter. The minimum widths of beaches OR platforms, steps from the edge of the water will be 2,00 m, width is recommended 3.50m.

The surface of the beaches or platforms will be horizontal, and will be awaiting at least 2% in direction perpendicular and opposite the glass towards channel of water harvesting perimetral, independent and removed from the glass.


Recreational vessels are composed by walls OR vertical walls and the bottom of the glass. The construction of the walls and merits of the glass will be solid lagging assured perfectly its stability, resistance and Uralelastotechnika.

For support or rest of users, may be a perimeter step at a depth low water levels below 1.20 m its width will be understood from 0.10 m and 0.15 m, seefigure NAT – 8the swimming Regulatory Standard.


All glass polyvalent must have first - kerb throughout its perimeter.

The first will limit the maximum level of water, desaguará the film surface of impurities, will grip users and mark the role of breakwater.

The first kerb will type overflowing with Flumes drain on the beach paved. See figuresP-REC-1aandP-REC-1b.

Part of the perimeter of the glass must be dedicated to access to the interior of the water. Can be done by stairs or vertical scales located in the corners of the lateral sides and unique points where the glass sudden changes of depth. other Will be placed at a distance not exceeding 20 m between them.

You can also be done through wide beach area or in descending staircase until the minimum depth of the glass.

To enable accessibility inside the water and leave it to disabled, on its own or with the help, they will be lateral or direct staircases to access the glass with balustrades and hydraulic lifters or manuals in the
beaches or platforms. The frontal staircases to access the glass will occupy part or all of the side.

Vertical ladders or not sobresaldrán scales the general level of the walls, so to avoid potential clashes between users and which evolve into water. It is recommended that a ladder at least scope the background to enable access of personnel responsible for cleaning and maintenance.

All the metal elements stainless will or will be adequately protected against the action oxidant water.

Vertical ladders or have scales the dimensions that are shown in FigureNAT- 10 a and bRegulatory standard swimming and they meet the standards: UNEEN 13451 “ Swimming pool equipment. General safety requirements and testing methods ” and “ 13451-2 UNE-EN Specific safety requirements and testing methods for additional scales, staircases and balustrades. ”

Mark the requirements of structural integrity and resistance to loads, skid resistance of the ladder will be such that will generate a minimum of twenty Angle to standard UNE-EN 13451 cited, as well as the requirements to prevent trapping so that the distance between the upper echelon and the wall shall not exceed 8 mm and in the remaining steps the distance between the step to the wall will be 0 – 8 mm OR in another case of 25 – 140 mm.

In recreational vessels are allowed the placement on the bordillo-rebosadero of devices capable to leisure users such as slides, sliders, walkways, etc. so that his disposal does not involve dangerousness for users who remain in the water.


The height between the surface of the water OR the pavement of the beaches OR platforms and the nearest obstacle (underside of roof, hang beam, luminaire, through air conditioning in covered facilities) should be entirely free and have a minimum of 4 m.


The lining of the facings of glass will be a waterproof material that enables easy cleaning and non-slip characteristics, so that skid resistance is such that it obtains a minimum Angle: 24º (Class (C) in kerbs rebosaderos pool and ladders and twelfth (Class To) in funds depth 1,40 m below; according to the test method described in the standard DIN 51097 which determines the non-slip properties for areas with bare feet.

The paving of the beaches should enable the movement of bare feet by its surface. The surface finish will rule dry and wet a character slip that prevents the slips, on the other hand surface roughness must be such that does not bother or injure the soles of the feet barefoot. Skid resistance of the pavement of the beaches OR platforms will be that you get an angle minimum of eighteenth (Class (B) according to the test method described in the standard DIN 51097 which determines the non-slip properties for areas with bare feet.

The pavement must have solved the superficial drains rainwater and / or splash of glass, insomuch that leads through a extraction independent of the glass first corresponding to the destination.


Usable water in a glass of recreation will proceed general network of public supply, in case your provenance is of rivers, lakes, springs, underground streams, etc. is necessary to perform the relevant studies and analyses to ensure quality and health authorization for use.

Water from the glass will be a water with sanitary conditions admissible, for which mark at any time requirements in accordance with the legislation in force that is of application and will be the corresponding sanitary authorization.

To achieve and maintain the water of glass with the required quality system, there will be a leak debugging and perform a treatment of disinfection of water for removing microorganisms and prevent the growth of algae and bacteria.

The purification system will be done through water recirculating the glass, within the timeouts authorized and with the contribution of water new necessary to maintain the quality and the water level of the glass.

The water, during the regular use of the swimming pool, must be constantly to its maximum level.

The water treatment equipment mark the safety requirements of standards UNE-EN 13451 “ Swimming pool equipment.

General requirements of security and test methods UNE-EN 13451-3 ” and “ specific requirements of security and additional testing methods to pool accessories for the treatment of water ”.

The water temperature all glass of recreational must be filled 25ºc ± 1ºc.

We must say that can only be using conventional energy for water heating of pools where in a covered premises. In outdoor pools can only be used for heating the water of the pool, alternative energy sources such as solar, air thermal waters or the ground. See Rules of Thermal Installations in buildings Additional Technical Instruction ITE 10.2 Refurbishment of pools.


Ambient air of all indoor pool that includes a glass of recreation, must be constantly at a temperature between 2ºc and 3ºc higher than the water in that glass, for technical reasons and physiological, with a minimum of 26ºc and a maximum of 28ºc.

The relative humidity should be between 55% and 70% be advisable to use as a value of design 60%. The maintenance of the relative humidity of the environment within the limits listed can be achieved by means of a heat pump, cooling, deshumedeciendo and warming the air at the same time.

In the ventilation system will be disposed of heat scrubber air expelled.

The use of conventional energy for these purposes should be restricted to supplement the heat required for the air ventilation and minimum transmission losses.

The use of Recuperators or heat pumps is mandatory for indoor pools greater capacity of 80 m3 or whose erodes surface water is over 50 m2.

See Rules Thermal facilities in buildings. Additional Technical Instruction ITE 10.2 Refurbishment of pools.


Artificial lighting is uniform and so that does not hinder the vision users and should not cause reflexes in the water. Mark the standard UNE-EN 12193 “ Illumination of sports facilities ” and get the following minimum levels of illumination:

(indoor and outdoor)
Horizontal illuminance
And med (lux) Uniformity
And min / Emed
Recreational use 300 0.5

The luminaires should not be placed on the vertical of the water, in case you are placed in this position must be available gateways for accessing the lights for conservation and maintenance.
