The Hidden Cost of Cheap Borehole Drilling

A quote that is far lower than everyone else’s is tempting. But a borehole is built mostly underground, where you cannot see what was left out until it starts to fail.

This guide shows where cheap quotes usually save money, what those shortcuts cost you later, and how to compare quotes fairly. For current prices, see our guide to borehole drilling cost in Kenya.

How a Cheap Quote Gets Cheap

Drilling costs money per metre, plus fuel, crew time, materials and testing. When a quote comes in far below the rest, something on this list is usually missing:

ShortcutWhat it saves todayWhat it costs later
No hydrogeological surveyKES 50,000Drilling in the wrong spot: a dry, weak or salty borehole
Shallower drilling than the site needsSeveral metres of drillingA borehole that fails in the dry season
Thin casing or no screensMaterialsSand, silt and collapse
No gravel packMaterials and timeMuddy water and clogged screens
No development or test pumpingOne to three days of workDirty water and a pump sized by guesswork
No water analysisLab feesUnknown health risks for your family
No permitsAbout KES 85,000Drilling illegally under the Water Act 2016
With Bonvic Drilling, the survey and permits are priced separately and every other item above is included in our per metre rate.

What the Numbers Look Like

At our 2026 air drilling rates of KES 6,500 to 7,200 per metre, a 200 metre borehole costs KES 1.3 to 1.44 million to drill. Add KES 50,000 for the survey and about KES 85,000 for permits.

So if someone quotes half that for the same depth, ask what is not included. Often the answer is the survey, the permits, part of the casing, the testing, or the depth itself.

The Real Cost of a Borehole That Fails

  • Paying to drill a second borehole, often at a deeper, better surveyed point
  • Buying water from bowsers while the problem is fixed
  • Replacing pumps damaged by sand or by running dry
  • Treating water that was never tested
  • Time lost on a farm, a rental building or a business

These costs are why a properly built borehole is cheaper over its 30 to 50 year life than a cheap one that fails early. Read why boreholes fail in Kenya for the full picture.

How to Compare Quotes Fairly

  • Ask every driller for a line by line quote
  • Compare the same depth, taken from your survey
  • Check what the rate per metre includes: casing, screens, gravel pack, development, test pumping, water analysis
  • Ask who handles the permits, and at what cost
  • Ask what happens if the borehole is dry, and get it in writing
  • Check references, photos of their rig and past work

Red Flags: Walk Away If You See These

  • A quote far below every other one you received
  • “We will get water, guaranteed” with no survey
  • No breakdown of what is included
  • Full payment demanded upfront
  • No written agreement or warranty

Paying Less Without Cutting Corners

If the full price is a stretch, do not cut the borehole. Spread the payments instead. With our staged payment plan you deposit at your own pace and we drill once 75% is paid. You clear the balance at the same pace while you already have water. See how to pay for a borehole in Kenya.
