@murchr the above pic is a sketch from the net. But it's a similar idea.

I got quotation from Doshi & Co (Hardware) Ltd. Nairobi. Prices for some items shocked me. Based on my quantities, total cost is coming to tune of sk200K+ Think

None return valve 3" @7,850
Gate valve 3" @7,880
Gate valve 0.5" @510
T-joint 3" @750
T-joint 0.5" @30
Pipe 3" @1,630
Pipe 0.5" @220
Horse pipe 0.5" roll @1,690
Elbow joint 3" @550
Elbow joint 0.5" @30


whether 200k is cheap or expensive depends on the scope of the project. i would advise u to consider using polypropylene (PPE) pipes and fittings (eg. gatevalves) that would be cheaper to buy and install (done by heat welding). PPE pipes are being commonly used for plumbing.

I have not bought yet. In fact as you suggest, I'm considering all "plastic" pipes and fittings. This is cheaper. Besides, I will use trenches, to bury the pipes underground to avoid damage by cattle.

How best would one be able to pump water from a spring that is about 100-200m down hill for domestic use? Is there any wazuan who has embarked on such a project?

The spring often floods when its raining how best can someone tap into this resource.

While doing my research, I found out that the most economical way is use of ram pumps. My neighbour in upcountry has used it successfully, 100m uphill (steep) and 3km flat distance to the home.

Look at this basic model from wikipedia

Basic components of a hydraulic ram:
1. Inlet — drive pipe
2. Free flow at waste valve
3. Outlet — delivery pipe
4. Waste valve
5. Delivery check valve
6. Pressure vessel
