Protect Your Borehole. Protect Your Health.
To safeguard groundwater quality and prevent contamination, the Water Resources Management Authority (WARMA) reminds the public that minimum distance requirements for boreholes are provided for under the Water Resources Management Act No. 21 of 2011 and the Water Resources Management (Groundwater and Boreholes) Regulations, 2018.
These minimum distances are based on aquifer type, pumping rates, and pollution risk, and are essential for protecting drinking water sources and public health.
📌 Minimum Distance Between Boreholes •
Most boreholes must be at least 50 metres apart
• Limestone and cavity aquifers require up to 100 metres
• Unconsolidated sediments such as Kalahari sands require up to 200 metres
📌 Minimum Distance from Pollution Sources
• Pit latrines and septic tanks – 30 metres
• Animal pens and farm sheds – 50 metres
• Fuel, fertiliser and pesticide storage – 100 metres
• Waste disposal sites and cemeteries – 500 metres
⚠️ Why this matters
Boreholes must be drilled away from pollution sources such as pit latrines, septic tanks, waste sites, and chemical storage areas. When boreholes are located too close to these sources, pollutants can migrate through the ground and contaminate the groundwater, increasing the risk of waterborne diseases and threatening household health and long term water security.
✅ Before drilling a borehole
Always consult WARMA, follow approved minimum distances, and obtain the necessary permits.
Safe spacing today protects Zambia’s water tomorrow.
