Borehole Casing Price in Kenya (Thika Edition): Everything You Need to Know Before Buying
💧 Introduction
Thinking of drilling a borehole in Thika or elsewhere in Kenya? One critical but often overlooked aspect is borehole casing. It might not sound glamorous, but without the right casing, your borehole could collapse, contaminate, or stop working altogether.
So, how much does borehole casing cost in Kenya? What influences the price? Which type should you go for in Thika’s unique terrain? Let’s break it down in simple terms.
📌 What is Borehole Casing and Why Is It Important?
Borehole casing is the lining material inserted into a borehole after drilling to stabilize the walls, prevent collapse, and protect water from contamination. It also helps maintain water pressure and supports the pump system.
📍 Why Borehole Casing Is Crucial in Thika
Thika lies in a region with volcanic and hard rock formations, but also patches of soft soils. This variation makes proper casing essential for boreholes to remain functional and safe.
Without quality casing, you risk:
Wall collapses
Contaminated water
Pump damage
Reduced borehole lifespan
💸 Borehole Casing Price in Kenya (2025 Update)
Prices vary depending on:
Material type (PVC or steel)
Diameter
Thickness (class)
Supplier or region
Here’s a quick look at average 2025 casing prices in Kenya, specifically near Thika:
| Casing Type | Diameter | Price Per Metre (KSh) | Use Case |
|---|---|---|---|
| PVC Class B | 4″ | 700 – 900 | Light duty – shallow wells |
| PVC Class C | 6″ | 1,100 – 1,400 | Standard for Thika boreholes |
| PVC Class C | 8″ | 1,700 – 2,200 | High-yield or deeper boreholes |
| Mild Steel | 6″ | 2,800 – 3,500 | Rocky or unstable formations |
| Stainless Steel | 6″ | 5,000+ | Corrosion-prone or premium setups |
Note: Prices fluctuate based on availability and the global cost of materials. Always confirm with local suppliers.
🔍 Factors That Affect Borehole Casing Prices
1. Material Type
PVC is cheaper, lighter, and corrosion-resistant.
Steel is durable, perfect for hard formations or industrial use — but pricier.
2. Wall Thickness / Class
Class B: Thinner, suitable for shallow or soft ground
Class C: Thicker and stronger, ideal for deeper boreholes in Thika
3. Borehole Depth
Deeper boreholes need more casing — sometimes 80 to 200 meters long — multiplying the cost.
4. Location and Delivery
Transporting casing to remote sites or areas with poor roads adds extra charges. Thika benefits from proximity to Nairobi, so delivery costs are generally lower.
5. Market Demand and Dollar Rates
Imported materials, especially steel and high-grade PVC, are tied to foreign exchange rates.

🔁 PVC vs Steel: Which Is Better for You?
| Feature | PVC | Steel |
|---|---|---|
| Cost | More affordable | More expensive |
| Corrosion | Resistant | Prone to rust (unless stainless) |
| Weight | Lightweight | Heavy |
| Installation | Easier, faster | Needs machinery |
| Lifespan | 15–30 years (proper use) | 25–50 years |
Verdict: For most Thika domestic and farm use, Class C PVC is more than enough.

❓FAQs
1. Can I use Class B PVC for my borehole?
Only if it’s shallow (under 50m) and in firm soil. Otherwise, go for Class C.
2. How long does PVC casing last?
15–30 years if properly installed and water is not too corrosive.
3. Can casing be reused?
No. Once removed, it can’t guarantee structural integrity or hygiene.
4. What if my borehole doesn’t hit water?
You’ll still pay for casing used up to that depth. That’s why pre-drill surveys are vital.
5. Is steel casing worth it?
Yes — in rocky areas or for high-yield commercial boreholes. But it comes at a higher price.
