Grundfos Dosing for Recreational purposes

At the Sun International Sun City Resort, South Africa is an environmentally friendly destination and has been awarded Gold Classification from the Heritage Programme for its commitment to the principles of sustainable and responsible environmental practices.  Situated in the bushveld of South Africa’s North West province and surrounded by the imposing mountains of the Pilanseberg, one would expect no less.

Unique in the context of world class resorts with a combination of features, unmatched anywhere draws thousands of visitors each year to its four top-quality hotels, magnificent sporting and recreational facilities, sought after golf courses, and the magical Lost City waterpark – The Valley of Waves.

The Valley of Waves is the central feature of the Lost City at the Resort.  It is one of the most advanced water parks in the world dominated by the Roaring Lagoon, a 6500m² wave pool with palm-fringed beach.  Hydraulic mechanisms can generate 1 1,8 meter wave every 90 seconds.  When waves are not generated, a bobbing cycle is generated in a diamond pattern.

The Water Park has five exhilarating flume rides:
* The Temple of Courage – swimmers drop a heart-stopping 17 meters down a 70 meter chute and race under a bridge and splash into a small pool at the foot of the slide.
* The Tarantula and The Scorpion are body slides.
* The Viper and the Mamba are flume rides where the swimmers float on large inflated tubes.
* The Lazy River is a gentle tube ride that flows endlessly round a kidney-shaped island.
* The Royal Bath is the large swimming pool adjacent to an amphitheatre which can accommodate an audience of over 800 people.

The Kiddies pool has an array of waterfalls and slides for younger children to enjoy.
There are two beautiful pools located at the Cascades Hotel.  Cascading waterfalls drop into the cold pool and the heated pool incorporates a slide and jacuzzi into its surroundings.   The Main Hotel, Cabanas and Vacation Club are also equipped with their own swimming pools set into the majestic surrounds of the Sun City Resort.

Problem
Historically Sun City’s pools were treated using chlorine gas.  There were great concerns regarding the safety of gas and the risks involved in its use.  Should there be a leak or an accident in such a large resort the consequences would be catastrophic.  The decision was made to find an alternative solution.  The Grundfos customer, Arch Chemicals came on board in 2006 providing a safer alternative to the chlorine gas.  Eleven systems were installed dosing Calcium Hypochlorite to disinfect all swimming pools.  

In 2010 a business review was called to assess the systems that has been running for a few years and had worked satisfactory in providing professional water treatment to huge volumes of water found at the Resort.  Yet again Sun City needed to make a decision to either revamp on the current units or install complete new systems.  Due to the increased maintenance due to old product wear and tear, current products and experience with the colometric method of testing it was decided to install complete new systems.

Grundfos Solution
Arch Chemicals conducted trials for almost a year, testing new control equipment for Sun City.  Variables such a cost, reliability, quality, ease of operation and back up support were assessed.  Grundfos was able to out rank all the competitors and with that, it was decided not only replace the older models with new Gurndfos models, but also to incorporate the Grundfos Control Systems.

Nine units were replaced with Grundfos DMI 208 Dosing units and incorporated with the Conex DIA 2 measuring amplifier and controller, for the measuring of chlorine and control the PH balance. These served to treat and disinfect all water for the Wave Pool, Body Slides, Tube Slides, Lazy River, Royal Bath, Main Hotel, Cabanas and the Cascades hot and cold pools.  Three of the old units remained in place, one for the Kiddies pool remained as it was due to the size being too small to justify the need for a replacement unit and one unit at the Vacation Club was still relatively new and the last as backup unit at the Wave Pool.

Result
With the Grundfos systems in place, we have achieved very favourable results as the systems are more advance and of high quality.  Less parts on the units resulted in fewer problems and lower maintenance costs across the board.  

Since the installations the site manager and Arch Chemicals has found that less time is spent checking the systems and there is no more inconsistent dosing resulting in wasted chemicals and the units provide them with constant accurate readings.

The pools are looking at their best as always with less effort required.
