New bicycle parkings

Vadim has just finished installing 2 new bicycle parkings at two entrances to the swimming pool: one beside the door near the river (see the picture), the other beside the petanca. As you can see, they are of the same type that we have been using in the last years.

Machine room now fully finished

As promised, here is how the machine room looks today, fully finished. Attached to he wall at the far end, you can see the devices that produce chlorine from salt, i.e., salt chlorinators. At the right side you see the pumps and filters. On the left side you see the light control system, more about that in the next weeks.

In order to desinfect the water, we add salt to it, and afterwards the water goes throught a salt chlorination process that uses electrical current to convert it to hypochlorous acid, a form of chlorine. Theoretically, it takes less of this purer, more effective chemical to sanitize the water and maintain a safe free chlorine level than with other forms of chlorine. It also eliminates the caustic acid that is present in liquid pool chlorine, or the inert ingredients that are a part of granular and tablet chlorine.

The salt level needed to produce chlorine is only about 3,000 ppm, which is less salt than is contained in the average human tear, and about 1/17 the salt found in sea water. A nice side effect is that the salt softens the water, giving it a smoother feel for swimmers.

This desinfection method has recently become popular in the private pools, also because of the easy of dealing with salt, avoiding dangerous chemicals. But it is not so popular among public swimming pools, althought the trend is towards it, as salt chlorinators are becoming more powerful.

One of the last signs

Vadim is fixing one of the last signs that were not yet positioned, this one is located in the south-east access to the new pool. You can see, farther in the picture, a garbage bin that is still waiting to be properly fixed.
Meanwhile, the machine room needs some signs and last touches, to be done during this next week.

Garbage bins around the pool

Pep is right now preparing the concrete bases for the garbage bins that are to be located all around the new pool. We expect to put three bins in the south side and four bins in the north side. The all are of a mixture of metal and wood decoration.
