The survey is expected to gather data on borehole locations, the volume of water being extracted, and whether the drilling activities are being carried out in line with existing regulations.
Karen, which is located in the southern part of Nairobi, has experienced significant development in recent years.
As new homes, institutions, and commercial projects continue to emerge, demand for water has also increased sharply.
This has led many property owners to rely on private boreholes as an alternative water source.
However, residents say the growing number of boreholes has raised fears that underground aquifers could be depleted if the situation is not properly regulated.
As part of the court’s orders, the Water Resources Authority has also been instructed to provide information about Nairobi’s permissible aquifer allocation.
This refers to the amount of groundwater that can safely be extracted without damaging the underground water system.
Experts say aquifers must be carefully managed because excessive pumping can lower water levels and affect nearby wells, rivers, and ecosystems.
The court’s directive is meant to help establish whether the current rate of groundwater extraction in Karen is sustainable or whether new restrictions may be necessary to protect the environment.
Residents who filed the complaints say they hope the survey will bring clarity and accountability to the issue.
They believe better monitoring and regulation of borehole drilling will help prevent long-term damage to the area’s natural water resources.
Environmental advocates have also welcomed the move, noting that urban expansion in Nairobi has increased pressure on underground water supplies.
