A big part of our business is rehabilitating wells that have declined in performance or replacing wells that have reached the end of their life cycle. We understand that replacing a well is a difficult decision and one that comes at a cost. We also understand that like anything else, a well will last a long time if taken care of but it will not last indefinitely. It does have a life cycle and the efficiency of your well declines over time, no matter the well.
Regular rehabilitation can increase the efficiencies of a well but seldom will the rehabilitation improve the well over and above what its efficiency was when it was installed. So do we recommend regular well maintenance, yes we do. But regular maintenance will not eliminate the need for a replacement well, it will only delay (sometimes significantly) the need for a replacement.
A hydrogeologist that I greatly respect wrote an article entitled “Life-Cycle Economic Analysis of Water Wells” that is based on his time designing and working with wells in the Phoenix valley. This is an insightful article. Unfortunately, pvc as a casing is not discussed in great detail in this article but in my mind I put pvc in with stainless steel in terms of enduring downhole (assuming no great stress on the pipe).
We hope you enjoy this article as it describes how well materials can play a big role in extending the life cycle of a well.
