There are various pipes around the outside of the swimming pool to take the water to the sand filtration unit, which is compulsory for a “public” pool, which is what this is considered to be. The pump then takes the water through the heat pump and brings it back to the pool – it will circulate the entire volume of water (70m3) in one hour. There is also an additional tube, which will feed the waterfall feature. These have to be covered in fine sand to protect them, before we can infill with gravel.
The same day, we excavated a couple of trenches. One to take a drain from around the pool in case the ground gets waterlogged and disturbs the pool structure. The other trench was to feel electricity to the pump house. These were quickly back filled (before I had a chance to get the camera out) and you would almost never know there were there!
All of this work was washed down with a beer for the boys, whilst I did the school run!
