Myrtha Pools builds the largest pool ever built for a World Swimming

Championship during the 15th FINA World Championships being held in

Barcelona 2013

Myrtha Pools has been selected for the construction of two 50-meter temporary pools

at the Palau Sant Jordi in Barcelona The venue will be host to the synchronized

swimming and swimming events during the 15th FINA World Championships in

Barcelona 2013. The events are being held from July 19 to August 4, 2013 in Barcelona.

Who is Myrtha Pools?

Myrtha Pools is the world's largest company in terms of constructing prefabricated

pools with over 50 years of experience. Founded in 1961 in Castiglione delle Stiviere

(Mantova, Italy), they quickly became a leader in the international swimming pool

market.

Thanks to their continuous research and development activity in developing the most

advanced technologies and reliable exclusive patents, the Company has made many

technological breakthroughs in the pool market.

Myrtha Pools has built swimming pools in over 70 Countries around the world and its

exclusive technologies have been selected for major international competition events,

including the Olympic Games and World Swimming Championships

What does Myrtha Pools mean for BCN 2013?

Myrtha Pools is present in BCN 2013 World Championships in two different venues at

the Palau Sant Jordi and Municipal Montjuïc Swimming Pool.

Palau Sant Jordi: Two 50-meter swimming pools were installed for Synchronized

Swimming and Swimming events.

The central pool of the world championships is the largest Competition Pool ever built

having dimensions of 50 meters long by 26 meters wide and a depth of 3 meters and a

total water volume of 4 million liters. This pool is 60% larger than the pool of built in

2003. The pool depth of 3 meters allows synchronized swimming competitions and is

26 meters wide allowing the use of 10 lanes for swimming competitions.

A warm up pool was built in the parking lot outside the Palau Sant Jordi with the

dimensions of a competition pool. It is 50 meters long by 21 meters wide and 2 meters

deep and utilizes the same technology of Myrtha Pools and allows athletes to train and

warm up before their performance in the main pool.

Municipal Montjuïc Swimming Pools: Diving competition.

Myrtha Pools has also been contracted to install, in the most emblematic city pools,

their innovative technologies. In the Montjuïc pools Myrtha Pools has installed a

completely new filtration system using the latest technology. The system has been

redesigned and two steel Defender filters with regenerative media and perlite have

been installed. This revolutionary system has allowed for the replacement of the 12

old sand filters and now utilizes only two, one for each pool. With this installation the

filtering capacity has been improved by a ratio of 20-1 with a water savings of 90%. In

addition, in the diving pool, an air safety cushion has been installed which is ideal for

athletes training.

What does the installation of the Myrtha pool at the Palau Sant Jordi mean?

When Myrtha Pools built two temporary pools at the Copacabana Beach for the World

Swimming Championships in Rio de Janeiro in 1995, the International Swimming

Federation saw the success of bringing swimming to the largest possible audience and

the Palau Sant Jordi allows, for the first time, over 12,000 attendees to view the

synchronized swimming events live.

Myrtha Pools has built the pool without damaging or drilling the original slab of the

Palau. A ring of precast concrete was laid and joined together by iron plates and is

used to anchor the steel structure of Myrtha Pools. The optimized self-supporting

structure is bolted together and does not require any welding. The stainless steel

structure of the pool consists of 170 panels 3-meters in height and is bolted together

with 30,000 stainless steel screws.

The two pools at the Sant Jordi were built in just 3 ½ weeks with both pools being

installed simultaneously.

What is the Myrtha Pools Technology?

The smart use of materials

Myrtha is the most exclusive and advanced technology in the swimming pool industry.

Its patented pre-engineered modular system, based on the use of laminated stainless

steel panels and buttress system, enables a Myrtha structure to attain perfect

waterproofing. Myrtha Technology provides the ideal solution to the many limitations

of traditional reinforced concrete structures and ordinary prefabricated swimming

pools.

The exclusive Myrtha technology has been developed thanks to intelligent and

superior materials: stainless steel for the structure, PVC for waterproofing, and special

materials for finishes.

Stainless steel - structure

The high quality stainless steel used in a Myrtha pool guarantees the extremely long

life of the structure regardless of the presence of highly aggressive soils or high water

tables. Myrtha uses exclusively engineered components bolted together, thereby

eliminating the need for welding, which is subject to increased corrosion. The use of

stainless steel materials ensures maximum mechanical strength of the panels,

buttresses and the other components that form the structure of the swimming pool.

PVC – waterproofing

The unique process of bonding PVC to the Myrtha steel panels ensures perfect

waterproofing. A hard PVC membrane is hot laminated to the steel in the

manufacturing process. A reinforced PVC membrane is used on the floor of the pool in

order to follow the contours of the concrete sub-surface.

Finishes

For high-level aesthetic finishes, Myrtha technology uses a wide range of exclusive

materials that match the colors of the PVC. Myrtha allows different finishes with the

use of ceramic tiles, stones or technological materials. This combination of materials

and colors allow the client to personalize each and every swimming pool according to

their specific needs.

How is it constructed?

The base frame

The base frame that outlines the Swimming pool is constructed with bolted steel sections that

form the supporting structure for the Myrtha wall panels. It is mechanically connected firmly

to the concrete footing by the use of chemical anchors. Rigidity is obtained by the use of

numerous threaded bars (anchor bolts), which are anchored in the perimeter curb. The

threaded anchor bolts also provide micrometric adjustment so that perfect leveling of the

structure is achieved.

The wall structure

The pool walls are formed by the use of sturdy, prefabricated stainless steel pools

panels. They are factory laminated with a permanently welded layer of hard PVC and

are then bolted to the base frame and to each other. Similar to the aviation industry,

the use of actual steel welding is avoided, thus there are no potential corrosion points

in a Myrtha structure. The exclusive use of stainless steel for the structural

components and PVC for waterproofing means that there is minimal risk of corrosion

with a high probability of leak-free construction.

The support buttresses

A vertical panel joint (3 feet), sturdy steel buttresses provide rigidity and strength to

the structure. Each buttress is anchored to the concrete footing. The structure is both

sturdy and elastic and is therefore ideal for installations with difficult ground

conditions (e.g. seismic zones, or on unstable soils).

The overflow gutter

The Myrtha overflow gutter is made with the same material that is used for the wall

panels and comes in a wide range of standard configurations. The gutter can be

supplied with a design (“diagonal flow”), which limits the evaporation of chemicals and

reduces the noise of the falling water. The patented Myrtha gutter grating has been

designed to meet the strictest anti-slip and load requirements and the gutter dropouts

can be supplied with silencers, which virtually eliminate noise.

Waterproofing

In order to allow for better waterproofing, all joints between the Myrtha sections are

welded with a liquid PVC or a reinforced PVC tape. The resulting joint is extremely

resistant, optically uniform to the panel surface, and aesthetically pleasant.

The floor of the pool is formed using a concrete slab, which needs only to provide a

smooth support surface. The slab is waterproofed by a special reinforced PVC

membrane produced specifically by Myrtha Pools for use in large swimming pools. On

the bottom and walls, the markings are installed according to FINA specifications.

How is the pool water kept crystal clear?

Myrtha Pools has introduced the largest number of technical advances in water

treatment ever used in a swimming competition and has taken steps that promote

ecology and sustainability. Three innovations are used to achieve this objective:

Optimal distribution of water in the pool through CFD analysis.

Regenerative filtration to 1 micron and no water consumption.

Green treatment with moss.

C.F.D. (Computational Fluids Dynamics)

The water distribution system in the pool is made with the latest generation of nozzles

Strahlenturbulenz that are the most efficient presently. This system developed by CFD

(Computational Fluids Dynamics) is an evolution of the traditional systems. It is based

on a series of nozzles, all different from each other, located in the walls of the pool and

arranged alternately on two opposing sides, thus avoiding the risks of pipeline facilities

at the bottom of the pools.

The nozzles generate two powerful current flows that allow rapid and complete

circulation of water in the pool, leaving no dead zones. The performance of the nozzles

is based on the Venturi effect with controlled turbulence and is designed to avoid

disturbing swimmers.

Using this nozzle system for quick and homogeneous distribution of water is very

important because it allows a hydrodynamic optimization that reduces chemical

consumption.

Filtration with regenerative media

The filtration is done with an automatic filtration system with continuous regeneration

of the filter bed. The Defender filter consists of a steel outer structure and a filter core

made up of a system of small flexible stainless steel spiral tubes wrapped in a dense

polyester mesh.

The Defender filter uses perlite as the filter medium. Perlite is a non-toxic fossil

powder that can filter particles as fine as one micron, and as a consequence decreases

the quantity of chemical products used while considerably increasing water quality and

transparency.

Another great advantage of the filter is the regeneration system of the media. The

daily automatic regeneration cycle optimizes the capacity of the filter and prevents

water consumption. The goal is to not waste a single liter of water during the

championships.

Ecological treatment with Moss

For the first time in a major international sporting event, disinfection and pH control of

the water will be carried out largely by an ecological system that uses no chemicals.

This system is based on the placement of moss in the balance tank of the pool. This

particular moss is grown in New Zealand and has been brought to these pools

exclusively by Myrtha pools.
