In Part 2 we looked at setting up the main water tank, the water collection from the roofs, as well as building the main water features for the water filtration.
In this post we will cover the sealing and finishing the water features, collecting the rain water from the first summer rains to fill up the pool, the water features and the tank. And then finally getting the water features running.
My goal was to only use rain water to fill up the pool, as well as get enough rain water to fill up the water features and the 2 water tanks.
But before the rain came i needed to get the brick and cement water features properly sealed otherwise the water will just slowly seep through the cement. For this we used FlashHappy Hypercrete, which is effectively a primer coat and which needs to be mixed with cement. At least 2 coats are required. Once this was done i applied 3 coats of FlashHarry FibreFlex. This required at least 7 rain free days to cure properly, so it needed to be done before the rains came. The picture below shows the second coat of the Hypercrete being painted on.
Next was the installation of the stainless steel water spouts to feed the water from one pool to the next, and which also serve to aerate the water from the waterfall effect. The spouts were made some left over stainless steel from the kitchen table tops.
After the mad rush to get everything ready for the summer rains, finally the first summer rains came. The rain water was collected from the roofs, into the tank, and then ran into the pool via a hosepipe connected to the tank. After a few days rain the pool was just about full, however it was an unexpected blackish colour. The picture below shows the pol almost full with rain water.
Once the pool was full i opened up the valves from the water tank to fill up the water features. This water was also a blackish colour.
Below is a picture of the running water.
The picture below shows the final reservoir where the water collects before being pumped back into the tank. This is done with the help of a float switch is the orange floating device. This float switch turns on the pump to pump the water back into the tank when the water reaches a certain height. The float switch then turns off the pump when the water level gets below a certain level. This is the only pump that is used. The water is gravity fed into the water feature.
Slowly over the next few days the blackish sediment sank to the bottom of the pool and was manually vacuumed out. After a bit of chlorine and running the pump for a few days the water starting clearing up and was swim-able. Then the salt was added and the chlorinator was fired up and the pool was finally up and running ready for summer 🙂
Next was getting the outdoor rainwater shower up and running. A basic metal support frame was built to hold the reed divider. The gas geyser was setup to get water from the rain water tank. And the hot rain water shower was up and running and working like a charm.
And below is a picture from the other side. There is still quite a bit of finishing work and plastering and painting to work to do, but its almost finished.
And finally a picture of the outside section with the clean pool and water features. The garden is also slowly coming together with indigenous plants, succulents and aloes.
And a quick pic of the original back garden before any construction started.
