Since the local community does not offer water supply in our region, we are forced to drill for water. The drilling was completed within a day. The water turned out to be enough. Officially, the well was 50 meters deep. Unfortunately, this turned out to be incorrect when we went to install the pump. The company was called back to drill to the agreed depth.
The tubes of 4 meter each are prepared to connect to each other to build a suction line.
The first tube is attached to the pump. Now screw on 10 tubes of 4 meters each one after the other. Specification of the pump we use: 1100Watt, 1,5HP, model ZB-95QJD5-67/10-1, suction depth 60 meters, With a suction depth of 60 meters you get 17 liters per minute. With a suction depth of 55 meters you get 25 liters per minute. With a suction depth of 15 meters you get 50 liters per minute.
The electric motors of the pumps are 3-phase motors. When connected to a 230 Volt mains supply and due to the absence of the 3rd phase, it must be taken into account that the power of the motor decreases to approximately 70% of the specified power. The diagram shows shows how the 3-phase motor is connected to a 230 Volt mains supply. By use of a capacitor a phase change is created, which is necessary to let the electric motor turn.
The picture below shows the connection box with capacitor
Three man are needed to hold the pomp atached to a loooong pipe.
The Kasetsart University carried out a water analysis with the measurement results shown on the picture.
Measured and recommended values.

It seems only hardness is outside the scope. Hard water is not a health risk but it will build mineral on shower head as example.We use strong magnets to soften the spring water. These are the best alternative to an expensive water softener with salt.
What's somewhat surprising is that the temperature of our well water remains consistently the same throughout the year. 28 (twenty-eight!) degrees Celsius, while the majority of voices on the Internet expect a temperature of around 15 degrees Celsius. So far it's been a nice energy saver because we like to shower at a temperature of around 38 degrees. It makes a big difference to heat the water from 28 to our beloved 38 degrees rather than from 15 to 38 degrees.
