Introduction
If you’ve drilled a borehole in Kenya—congrats! That’s a smart move for securing a reliable water source. But don’t stop there. One often overlooked yet critical component of a borehole system is the borehole cap or cover. It’s not just a lid; it’s the guardian of your water supply. Let’s dive into why it’s essential and how to choose the right one.
Purpose of a Borehole Cap or Cover
A borehole cap serves several purposes, all of them vital for safety and water quality:
Prevents Contamination: Keeps dust, debris, and pathogens out of your water system.
Protects Pump and Pipework: Shields sensitive components from exposure and damage.
Avoids Accidents: Uncovered boreholes are a danger to children, pets, and livestock.
Stops Unauthorized Access: Prevents tampering, vandalism, or water theft.
