How long does a water well last?
A properly constructed and maintained borehole well can last 20 years or more with routine upkeep and access to spare parts.
But that is only part of the story. We have personally seen wells that are 30 and even 40 years old that are still going strong. So why do some wells last for decades while others fail after only a few years? In most cases, it comes down to how the well is managed after installation.
With a regular schedule of preventative maintenance, strong community ownership, and a clear commitment to the well’s long-term care, there is no reason a borehole well cannot last for decades and provide clean water to generations to come. The key to success is community participation.
Long-term success depends on local ownership
A well is not a one-time project that can simply be installed and forgotten. Like any piece of infrastructure, it needs ongoing care. When a community takes responsibility for the well, sets clear expectations, and responds quickly when small issues appear, the well is far more likely to remain functional for many years.
This is one reason why sustainability matters so much in rural water projects. At Drop in the Bucket, we have seen that the long-term success of a well depends not just on drilling it correctly, but also on preparing the community to manage it well after construction is complete.
Some parts wear out faster than others
An India Mk II hand pump has several parts that will gradually wear down over time. That is normal. A well used by hundreds of people every day will eventually need maintenance and replacement parts.
One of the most important components is the riser pipe. Traditional galvanized iron riser pipes will rust over time. Eventually, they may weaken, break, or begin to affect the taste of the water. Stainless steel riser pipes are a newer and far more durable solution. They cost more upfront, but because they do not rust, they often save money over the life of the well.
Some manufacturers also produce PVC riser pipes, which do not rust and can be a cost-effective option for shallow wells. However, in our experience, they are not ideal for deep wells. When used at greater depths, the weight of the water column can sometimes cause the pipes to pull apart. For that reason, we do not use them. We prefer stainless steel riser pipes because they are stronger, more reliable, and better suited for deep borehole wells.
Maintenance is not optional
Outside of the riser pipes, other parts of the pump will also wear out over time and need to be replaced. Even the cement apron around the well may eventually need repair or replacement. None of this should be viewed as unusual. Repairs are not an anomaly. They are a normal part of the life of any well.
That is why every organization drilling wells should also be preparing the community for long-term maintenance. Communities need trained pump mechanics, access to spare parts, and a system for raising funds to cover repairs when they arise. Without those systems in place, even a well that was properly drilled can fail long before it should.

Why some wells last for generations
When everyone involved honors their responsibilities, wells can and should last for several generations. That means the NGO must build the project properly, use durable materials, and provide training. It also means the local community must stay engaged in maintaining and protecting the well.
A well that is cared for properly can continue serving children and families for decades. In that sense, the lifespan of a borehole well is not determined only by engineering. It is also determined by the strength of the systems and people responsible for keeping it running.
