Plan Your Borehole in Minutes
Six free tools that take you from first idea to a clear plan. Work out the cost, see the savings, size your pump, plan your irrigation, and diagnose problems.
Thinking about a borehole but not sure where to start? Our free borehole calculators do the hard maths for you in under a minute each.
Each tool answers a different question, and together they give you a complete picture before you ever pick up the phone. They are built on our real field experience drilling across all 47 counties of Kenya since 2010.
Planning a New Borehole
Start here if you do not have a borehole yet. These three tools follow the natural order of planning one.
Cost Calculator
Estimate the total cost of your borehole project. Choose your county, depth, casing and equipment, and get an instant breakdown tailored to your site.
Open Cost CalculatorSavings Calculator
Find out how fast your borehole pays for itself. Compare what you spend on water now against owning a borehole, and see your long term savings.
Open Savings CalculatorPump & Tank Selector
Work out the right pump size and water tank for your needs. Enter your depth and demand to get a recommendation based on real engineering.
Open Pump & Tank ToolRunning or Fixing a Borehole
Already have a borehole? These three tools help you cut your running costs, plan your farm water, and work out what has gone wrong.
Solar Pump Savings Calculator
See what grid power is really costing your pump each month, and how fast a switch to solar pays for itself. Enter your pump size and tariff.
Open Solar CalculatorIrrigation Water Calculator
Work out how much water your crops need each day, and the borehole flow and storage that demand implies. Covers crop, area, climate and method.
Open Irrigation ToolBorehole Problem Diagnoser
Weak flow, dirty water, sand, or a pump that has stopped? Tell us the symptom and get the likely causes and the recommended fix in seconds.
Open DiagnoserHow to Use Them Together
If you are planning a new borehole, the first three tools follow the natural order. Start with the cost calculator to see what your project might cost, then use the savings calculator to see how quickly that cost pays back.
Next, the pump and tank selector tells you what equipment you will need. Farmers should add the irrigation calculator first, since your crop water demand sets the borehole yield you need.
If you already have a borehole, the problem diagnoser is the place to start when something is wrong, and the solar savings calculator shows what you could save on electricity.
By the time you call us, you already know your numbers. That makes the conversation faster and the quote more accurate.
