Our future drilled well will also need a ring (designed for drilled wells). After all the installations the ring will be very important for maintenance. We bought our ring right after the drilling day and placed it in its place to see if it fits there. The diameter of our ring is 80cm. That is the typical size for a drilled well for households. Of course, before the fitting, we had to prepare the area first.
In future posts, you will see how the ring is placed. Apparently, no one took a photo from that step. XD
