Once a water project is completed, it belongs to the community it serves. Through training and engagement during implementation, communities are equipped to manage day-to-day operation and afford routine maintenance.
We remain engaged beyond construction so that, if challenges arise that exceed local capacity, additional technical support can be arranged. Project lifespan depends on the type of system, environmental conditions, and maintenance practices.
Below are typical lifespan ranges for common water solutions:
1. Drilled Wells with Hand Pumps (Boreholes)
A drilled well, commonly known as a borehole, has an estimated lifespan of 20–50 years.
The hand pump installed on the borehole can last up to 15 years when properly maintained.
To maximize longevity, we assess groundwater conditions before drilling and oversee construction quality. In areas with corrosive groundwater, we prioritize durable materials—such as stainless steel pipes instead of galvanized iron—to reduce corrosion and extend system life.
2. Piped Water Systems
Piped water systems with tap stands typically have a lifespan of 10 years or more when properly designed and maintained.
When planning these systems, we account for population growth projections of up to 20 years, allowing systems to be expanded as communities grow. High-quality materials and proper source design are critical to long-term performance.
3. Rainwater Collection Systems
Rainwater harvesting systems generally last 10–20 years, depending on tank materials, roof catchment quality, and regular upkeep. With proper maintenance, these systems can provide reliable seasonal water access for households and institutions.
4. Borehole Rehabilitations
Rehabilitated boreholes can extend the life of an existing water point by 10–20 additional years, depending on the condition of the original borehole and the scope of repairs. Rehabilitation often restores functionality at a lower cost than new drilling.
5. Solar-Mechanized Systems
Solar-powered water systems typically have lifespans of 15–25 years. While pumps and solar components may require periodic replacement, the overall system design allows for long-term, high-volume water delivery when maintained properly.
6. Household Connections
Household water connections can last 10–20 years with proper installation and routine maintenance. Longevity depends on pipe quality, water pressure management, and ongoing system care.
Designed for the Long Term
Across all systems, longevity depends on three key factors:
Appropriate design based on local geology and population trends
High-quality materials suited to environmental conditions
Ongoing community management and maintenance
When these elements are in place, clean water systems have a strong likelihood of serving communities reliably for a decade or more—and often much longer.
