Selecting the Right Filter for Borehole Water in Kenya: A Complete Guide
Borehole water is a valuable and often necessary source of water in many parts of Kenya, especially in rural and peri-urban areas. However, borehole water is not always safe to use directly due to the potential presence of contaminants such as iron, fluoride, nitrates, bacteria, and sediment. Choosing the right filtration system ensures your water is clean, safe, and tastes great.
Let’s break down everything you need to know.
🔹 Why Filtering Borehole Water is Important
Borehole water may look clear, but it often contains:
Sediment (sand, silt, rust)
Dissolved minerals (iron, manganese, calcium)
Heavy metals (lead, arsenic)
Bacteria and pathogens (E. coli, coliform)
Excess fluoride or nitrates (in some regions)
Filtering ensures:
✅ Health and safety
✅ Protection of household appliances
✅ Improved taste and smell
✅ Longer lifespan of plumbing
🔹 Step-by-Step Guide to Selecting a Filter for Borehole Water
1. Water Testing Comes First
Before you buy any filter:
Get a professional water test to identify contaminants.
Most local labs or companies like Protech Water and Solar Equipments in Kenya offer affordable water testing.
2. Understand the Common Contaminants in Kenyan Borehole Water
Iron/Manganese: Stains, metallic taste, pipe blockages
Hardness (Calcium/Magnesium): Causes scale in pipes
Fluoride: Harmful if above 1.5mg/L
Bacteria: Can cause waterborne diseases
Turbidity: Cloudy water from particles
🔹 Types of Filters and Treatment Systems
A. Sediment Filters
Purpose: Removes sand, silt, rust, and large particles.
Recommended: 5 to 20 micron pre-filters.
Installation: First stage of filtration.
B. Activated Carbon Filters
Purpose: Removes chlorine, odors, and improves taste.
Limitations: Doesn’t remove heavy metals or microbes.
C. Iron/Manganese Filters
Oxidation Filters: Use air or chlorine to oxidize and filter out iron.
Greensand Filters: Common in Kenya for iron and manganese removal.
D. Water Softeners
Purpose: Removes calcium and magnesium.
Benefit: Prevents scale in geysers, kettles, and pipes.
E. Reverse Osmosis (RO)
Purpose: Removes fluoride, heavy metals, nitrates, and TDS.
Best For: Drinking and cooking water (not for whole-house unless specially designed).
F. UV Sterilizers
Purpose: Kills bacteria and viruses.
Always installed after all filtration stages to ensure clear water for UV to work effectively.
G. Ultrafiltration (UF)
Alternative to RO: Keeps minerals, removes bacteria and sediment.

2. How do I know if my water is safe after filtration?
Have the water tested again post-filtration. Ensure it’s clear, tasteless, and free from bacteria.
3. How much does a borehole water filter system cost in Kenya?
Prices range from KSh 15,000 to KSh 150,000 depending on the complexity and capacity.
4. Is RO necessary for borehole water?
Only for drinking water if your borehole has high fluoride, nitrates, or heavy metals.
5. Can Protech Water and Solar install and maintain the system for me?
Yes! They offer full installation, water testing, and maintenance services across Kenya.
