The verdict in three sentences
A water borehole drilling contractor in Nairobi is judged by NGOs, UN agencies and county governments on its track record before the financial bids are even opened. A website showing a map of 350 completed boreholes, success rates by geological zone, the rig fleet and the funders served turns a line in the bid file into verifiable proof. On Kolonell's website grid, this site costs 800,000 to 3,500,000 FCFA (1,220 to 5,340 EUR) and is delivered in 4 to 7 weeks, a cost that a single extra drilling lot repays several times over.
What evaluation panels check
Borehole tenders funded by UNICEF, the World Bank, bilateral donors, international NGOs or county budgets follow a similar logic: a pass or fail technical score, then price comparison. Evaluators are trying to reduce one specific risk, a dry borehole or an abandoned site in a hard-to-reach area. A programme officer torn between two bidders will almost always look them up online.
| What the panel assesses | Bid document | What the website should show |
|---|---|---|
| Similar experience | Reference list over 5 years | Interactive map of 350 boreholes, filterable by county and year |
| Geological expertise | Technical methodology | Success rate by zone: basement rock, volcanic Rift areas, sedimentary north-east |
| Equipment capacity | Equipment list | Rig fleet with dated photos: drilling rigs, compressors, support trucks |
| Key personnel | CVs of hydrogeologists and site supervisors | Technical team profiles with years of experience |
| Administrative standing | Registration, permits, turnover | NCA registration, Water Resources Authority permits handled, counties covered |
| On-time delivery | Completion certificates | Funders served, lots delivered, average time per borehole |
In Kenya, success rates vary sharply between basement aquifers, volcanic formations and the arid north-east, and depend heavily on the quality of the hydrogeological survey. Publishing an honest rate, for example 74% in basement areas and 86% in volcanic zones, reassures far more than a blanket claim of "100% satisfaction".
Kolonell's three tiers applied to a drilling contractor
Kolonell's website grid scales with the size of the company and how often it bids.
| Tier | Price | Content for a drilling contractor |
|---|---|---|
| Starter | 800,000 to 1,200,000 FCFA (1,220 to 1,830 EUR) | 5 pages: company, services, reference list, equipment, contact |
| Growth | 1,200,000 to 2,000,000 FCFA (1,830 to 3,050 EUR) | Borehole map, project sheets, success rates by zone, extra languages on quote |
| Premium | 2,000,000 to 3,500,000 FCFA (3,050 to 5,340 EUR) | Growth + detailed project sheets with before and after photos, advanced SEO, refined animations |
| Basic maintenance | 35,000 FCFA a month (53 EUR) | Technical updates and backups |
| Standard maintenance | 75,000 FCFA a month (114 EUR) | Basic + monthly addition of new boreholes and references |
| Premium maintenance | 120,000 FCFA a month (183 EUR) | Standard + performance tracking and priority support |
For comparison, a Nairobi freelancer charges KES 150,000 to 400,000 for a simple site, often with no map and no reference updates, and a local agency KES 500,000 to 1,500,000 (2026 order of magnitude). The difference lies in upkeep: a map frozen in 2023 works against you in front of an evaluator.
Preparing content in 4 to 7 weeks
The timeline depends mostly on data collection. The company's project lead gathers, for each borehole: GPS coordinates, date, depth, test-pumping yield, result (productive or dry), funder and client. This information already sits in completion reports; the job is to consolidate it in one spreadsheet that the site turns into a map and statistics.
Watch for sensitive data: some funders ask contractors not to publish contract values or precise water-point coordinates in insecure areas. In that case, publish the county and sub-county without exact coordinates.
Mini case study
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Wanjiru, managing director of a 45-person drilling contractor in Nairobi, answers about 40 tenders a year and passes the technical stage 15% of the time, so 6 shortlistings. She chooses Growth at 3,050 EUR with Standard maintenance at 114 EUR a month, so 4,418 EUR in year one.
With a reference map, project sheets and published success rates, the cautious assumption is a 20% shortlisting rate, or 8 bids retained. At one award for every three shortlistings, that is about 0.7 extra contract a year. A typical lot of 10 equipped boreholes at KES 3.5 million each is worth KES 35 million; at a 12% net margin it earns KES 4.2 million, roughly 28,000 EUR. Weighted at 0.7, the expected gain (about 19,600 EUR) is more than four times the site's first-year cost.
FAQ
Do funders really look at bidders' websites?
Increasingly, especially during pre-award checks. An up-to-date site with 350 mapped references makes that check easy and avoids requests for extra documents that delay the file by 1 to 2 weeks.
Should we publish dry boreholes?
Yes, as a success rate by geological zone. A 74% rate in basement areas, explained by your siting method, is more credible than a perfect figure evaluators know is unrealistic.
Is a French version useful?
For contracts in francophone Africa and some European donors, yes. It is quoted separately depending on the number of pages and project sheets, on top of the 800,000 to 3,500,000 FCFA grid.
How long until the site is live?
4 to 7 weeks, including 2 to 3 weeks to consolidate borehole data. The sooner the reference spreadsheet is ready, the closer you get to 4 weeks.
Can the website feed directly into tender files?
Yes: each project sheet can be exported as a PDF and attached to the technical references. With Standard maintenance at 75,000 FCFA a month (114 EUR), new boreholes are added every month.
