Benefits of Commissioning & Training

Following construction, the commissioning of the pool system is critical to ensure that it is working properly and as it was designed, before handing over the operation of the pool to its Owner. These are the people who will be operating and maintaining their body of water on a daily basis.

 

COMMISSIONING

During commissioning, all pieces of equipment are started-up, run, and programmed. I have learned first-hand how important it is to allow for the proper amount of time for this to occur. Allowing a few weeks to complete the commissioning ensures that each piece of equipment has enough time to operate as designed. If anything goes wrong it can be rectified immediately.

 

The set-up of the system begins when the water is introduced into the pool. Once the water starts to run through the piping, it is also running through each piece of equipment that is required to operate the system. Here are a few examples of equipment that requires set up;

 

CHEMICAL CONTROLLER

The chemical controller, which monitors and reads the pools chemistry, requires some initial set up. The controllers parameters are set to ensure that if the chemistry is not within those parameters, the controller alarms to alert the operator that the water chemistry requires attention. This can take time to complete to ensure accuracy.

 

POOL PUMP

After the pump is started up, it should be allowed to run for a period of time to ensure that there are no leaks. Seals in a pump can be dry and cracked before the pump is even installed. You won’t be able to physically see this issue until the water is running through the system.

 

Those are just two examples of the numerous pieces of equipment that are involved in pool systems, most of which require set up. There is always a possibility that equipment can fail, so ensuring everything is commissioned by the time the system is fully operational means less chance of equipment or system failure. When there is a failure after the pool is fully operational, it could mean that the pool would have to be shut down and closed to its patrons. This is something that all Owners want to avoid at all costs.

 

TRAINING

Once the pool is completely commissioned, it is now the perfect time to train those individuals who will be operating the pool on a daily basis. Every pool system is different, so even if a person has experience with pool systems, the new system could be slightly different. A controller could be updated from the previous version, or the system could include a UV system that the Operator has no previous experience with.

 

Training sessions cover many techniques including:

  • How the piping system flows
  • How to operate the controller
  • Understanding what can go wrong
  • What to do if the pool overflows
  • How to adjust chemistry of the pool
  • What to do if the system equipment is in alarm

Allowing those people the opportunity to watch and learn through a hands-on training session has amazing benefits for them in the future operation of the pool. When Operators have the understanding and knowledge that they need, their confidence level is increased, allowing them to maintain the system properly, and promptly deal with any issues that may arise, shortening their down time.

 

As you can see, commissioning and training benefits all parties involved in the operation of the pool system. The time for this to occur should be considered in every construction schedule.

Pool Finishes: Options & Considerations

When planning the construction or renovation of your pool, whether commercial or residential, one of the many decisions you will need to make is the pool finish. There are several options available to both commercial and residential pools, there are also many factors to consider when choosing a finish. Cost is usually the first thing on everyone’s mind, when making any purchase. However, there are many other considerations that will often times outweigh the initial cost. The intended use of the pool is an important factor to consider when determining the finish of a pool. Residential pools, which have a lower use, can get away with one of the more budget-friendly options, as there is less wear and tear. A low-cost finish will save some money upfront however, repairs and refinishing will be required much sooner than some of the longer lasting, high-end finishes.          

 

TILE FINISH

Tile has been used as a pool finish for years and is known to be the most durable finish. When applied correctly, a tiled finish can last for decades before requiring any replacement. Tile offers the pool owner a wide variety of colour options and design possibilities. Due to the preparation and labour required for installation, this high quality finish option comes at a higher initial cost. However, over time it will pay for itself, through the savings on repairs and replacements.

 

ADVANTAGES

  • Durability & Longevity: A tiled finish will last decades if applied correctly, and compensate for the higher upfront costs.
  • Easy to Repair: If there is an issue with isolated delamination of tile, it is very easy to replace small areas of tile and match to the existing, without having to re-finish the entire pool.

DISADVANTAGES

  • High Upfront Cost: Correctly installing tile, comes with heavy labour including; the preparation of the subsurface, laying the tile and grouting the tile.
  • Deterioration of Grout: Though tile has a very long life span, the grout will deteriorate much quicker. Over time grout will begin to wear out of the joints and discolour. Normally, grout will be required to be replaced much sooner than the tile. 

PLASTER FINISH

Plaster is one of the most prominent pool finishes around, and has been used for several years; a quicker install than products like tile is the main reason for its popularity. Plaster is shot onto the pool walls, similar to gunite, and then toweled to give it a smooth consistent finish. A plaster finish does require some sort of tile border at the waterline as the waves against the plaster will cause it to deteriorate quickly.

 

ADVANTAGES

  • Cost & Durability: Even with the high level of durability a plaster finish offers,  the cost is relatively low.
  • Aesthetically Pleasing: Plaster provides a very nice finish which is smooth and able to form to any shape or design.

DISADVANTAGES:

  • Pool chemistry can very quickly deteriorate a plaster finish if not properly maintained; low pH in the water is a big concern and requires experienced supervision.
  • With age, pool plaster will start to delaminate and cause sections of the plaster to pop off, having to re-plaster a pool is very costly.

PAINT FINISH

Painting a pool is a very inexpensive method of finishing any pool, and is typically used in a commercial application for community or public pools. Though painting a pool is an economical and quick finish option, over several years the paint will chip and need to be repainted. A parge coat is required before painting to ensure all honeycombing of the concrete is filled, leaving the floor and walls smooth.

 

ADVANTAGES

  • Low Cost & Project Schedule: The cost of the material and labour required to complete the work is extremely low and can be completed quickly.
  • Low Risk of Damage: Since paint is applied to a cementations backing, there are no concerns about damaging or puncturing the finish from items in the pool.

DISADVANTAGES

  • Frequency of Repairs: A paint finish will need to be refinished every 3 to 5 years, requiring the existing paint to be blasted off before repainting.
  • Imprefections: If the subsurface of the pool is not done perfectly any imperfections such as honeycombing or rough parging will show through and can cause injuries to swimmers.

VINYL LINER FINISH

Traditionally Vinyl liners have been a typical residential pool finish, due to the relatively low cost and quick installation. Liners can and have been used for commercial applications however, due to the low durability of a liner it is not very common. Vinyl liners can be used in both stainless steel and concrete pools.

 

ADVANTAGES

  • Low Cost: In comparison to other finishes, liners can be an economical alternative. The liner itself is relatively inexpensive, in comparison, and installation labour is a significantly lower cost.
  • Creates a Water Tight Tank: This benefit can be an efficient solution, saving time and money, to a deteriorating concrete pool, which has started to leak. 

DISADVANTAGES

  • Deterioration: Vinyl liners are more susceptible to deterioration caused by harmful UV light and poor water chemistry, resulting in the liner needing to be replaced sooner.
  • Easy to Damage: Vinyl liners can very easily be damaged from foreign objects, such as tree branches or toys falling into the pool. Punctures in the liner will result in water getting behind the liner, causing the pool to leak and the liner to bubble out.
