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.
