Why You Should Care About Digital Metering For Your Borehole
When you’ve spent up to millions on a borehole, guessing how much water you use is a big risk. A digital water meter gives you:
1. Accurate usage data.
2. Leak and fault detection
3. Better cost control for apartments, farms and institutions, clear readings mean fair billing and less conflict.
4. Remote visibility – many meters send data to your phone or web portal.
The Water Resources Authority (WRA) regulates all significant groundwater abstraction through permits. As part of that, borehole owners are required to measure and report water use at abstraction points using water meters. Non compliance with permit conditions can attract fines or even orders to stop abstraction.
Rocktech Geoengineering helps you design, drill and equip boreholes with proper metering from day one by:
1. Selecting the right digital meter for your pump and flow range.
2. Installing it correctly and integrating it into your system.
3. Aligning your setup with WRA requirements while keeping the operation simple for you.

Before You Buy a Water Tank, Answer These 5 Questions
A water tank is not just a container; it is the heart of your water supply at home, on the farm, in apartments, schools, or industry. The wrong choice can mean leaks, contaminated water, or replacing the tank much earlier than planned.
At Rocktech Geoengineering Services, we design and build complete water systems, and we always start with five simple questions:
1. How much water do you really need?
- A typical home might need 3,000–10,000 liters; farms, schools, apartments and hotels often need far more.
2. Where will the tank sit, and for how long?
- Above ground tanks are easier to inspect, repair and replace.
- Underground or partially buried concrete tanks save space and protect water from heat and vandalism, but they must be properly designed for soil conditions and waterproofed to avoid leaks.
3. Which material fits your environment and budget?
- Plastic (poly): Light, quick to install, corrosion resistant and usually the most affordable. Great for most domestic and light commercial uses, but long term UV exposure, impact and poor bases can shorten their life.
- Concrete: Heavy, very durable and ideal for large, permanent reservoirs or underground tanks on farms, estates, institutions and industrial sites.
- Steel/metal: Strong and suitable for larger volumes or elevated tanks. Needs proper internal coating and ongoing maintenance to prevent rust and protect water quality.
4. What will the water be used for?
- Drinking and domestic use require food grade materials, covered tanks, screened vents and secure lids to keep out dust, insects and animals.
- Irrigation, livestock or industrial use can be more flexible, but we still check chemical compatibility and any treatment you plan now or in future.
5. Is the base, plumbing and maintenance plan in place?
- A good tank on a weak or uneven base will tilt or fall. We design suitable concrete pads or ring beams, correct inlet and outlet levels, overflows, washouts and access for cleaning.
Talk to us before you buy. We’ll look at your site, consumption, plans and budget, then recommend the most suitable plastic, concrete or steel tank setup for you.

Before you drill a borehole on your land, talk to us first.

Too many boreholes still start with a rig and a prayer, which is fine for faith but not for protecting your water source, complying with regulations, or long-term cash flow.
At Rocktech Geoengineering Services Ltd, we follow a clear 4 step process to turn a borehole from a guess into an engineered groundwater asset:
1. Survey first, permits second, rig last- We begin with a proper hydrogeological survey and use it to support WRA approval before any rig is mobilized.
2. Design the borehole, don’t guess it- Using the survey, we set the target depth, casing and screen configuration, and build clear deliverables into the contract: drilling log, step and constant rate pumping tests, water quality tests, and a signed completion report.
3. Drill under supervision- We work with registered drillers, share the permit and the survey report upfront, and provide hydrogeological supervision so that what is drilled on site matches what was designed and approved.
4. Complete, protect, then license- We oversee proper development, sanitary sealing and headworks protection, verify water quality, and support you through the abstraction permit process.
If your process starts with “call the driller”, you are skipping the half that actually protects the aquifer and your investment.
If you are planning a borehole, contact Rocktech Geoengineering Services Ltd to survey, design, and supervise it as a true engineered asset

Choosing the Right Water Tower for Your Borehole

Once the borehole and pump are in place, the next big decision is the water tower. Get it wrong, and you end up with low pressure, cracked structures, or an overpriced monument. Get it right, and your system runs quietly for years.

At Rocktech Geoengineering Services, we look at four questions before recommending a water tower design in Kenya.
1. How much pressure do you need?
Water pressure from a tower is mainly determined by height. As a rule of thumb, about 10 meters of water height corresponds to about 1 bar of pressure. If you have higher buildings, long pipe runs, or irrigation sprinklers, you may need more height or a booster pump rather than just building an extremely tall tower. The goal is to balance comfortable pressure with safe, economical construction.
2. How much water do you need to store?
Your daily and backup demand drives tank volume:
- Homes: often 1–3 days of typical use.
- Farms: enough to cover key irrigation hours, especially when power is limited.
- Estates and institutions: demand profiles plus backup requirements.
Remember that a full 10,000 liter tank weighs over 10 tonnes. Oversizing “just in case” can push structural and foundation costs much higher than necessary.
3. Steel or concrete structure - which is better for you?
a) Steel towers – good when you need speed and flexibility
- Faster to fabricate and install, and easier to modify or extend later.
- Lighter structures are helpful where soil bearing capacity is moderate or access is tight.
- Require proper corrosion protection and periodic painting, especially in coastal or industrial areas.
b) Reinforced concrete towers – good when you want long term permanence
- Very durable when correctly designed and built, with good fire resistance.
- Heavier and more rigid, so the foundation and design must be done properly.
- Higher upfront cost and longer construction time, but low visible maintenance if detailed correctly.
4. Safety, stability, and maintenance are non negotiable
Whatever you choose, a water tower is a heavily loaded structure:
- Foundations should be sized for soil bearing capacity, wind, and seismic forces.
- Ladders, platforms, and guardrails are essential for safe inspection and cleaning.
- Access and maintenance planning from day one reduces life cycle costs and safety risks.
Cutting corners here creates real risk to people and property, not just minor cracks.
At Rocktech Geoengineering Services, we design borehole systems as a whole: borehole, pump, rising main, tower, and distribution network. We help clients choose tower height, tank size, and structural type that match their actual demand, site conditions, and budget.

Selecting the Right Submersible Pump for Your Borehole

For many borehole owners, the real frustration starts after drilling – when the pump keeps failing, cannot fill the tank, or slowly kills the borehole by over pumping. In most cases, the issue is not the brand; it is wrong sizing and design.

At Rocktech Geoengineering Services Ltd, we see four basics that every borehole owner in Kenya should understand before buying a submersible pump.
1. Start with your borehole data
Use your borehole completion and test pumping report: static water level, pumping (dynamic) water level, total depth, casing diameter, and tested yield.
2. Be clear on how much water you really need
Households, farms, institutions, and estates all have very different daily and peak demands. Your target flow rate (m³/hr) should sit safely below the tested borehole yield. Oversizing at this step is one of the fastest ways to stress a borehole and waste energy.
3. Know the “total head” your pump must work against
A proper design considers the dynamic water level during pumping, the height above your tank, and friction losses in pipes, bends, and valves. If you underestimate total head, the pump struggles and under delivers; if you grossly overestimate it, you pay more for a bigger pump and motor than you actually need.
4. Match the pump to the borehole and the power source
The pump must physically fit inside the casing, deliver your required flow at the calculated head, and match your power set up.
A submersible pump is not just an accessory; it is part of the borehole design. Getting it wrong costs you in repairs, power bills, and sometimes a damaged aquifer. Getting it right gives you reliable water at the lowest sensible life cycle cost.
At Rocktech Geoengineering Services Ltd, we help clients move from borehole data and water demand calculations to a correctly sized pump and control system, so that the borehole, pump, and power all work together.

Are You Thinking of Drilling a Borehole? Read This Before You Drill

If you are considering drilling a borehole in Kenya, the most expensive mistake is starting with a rig rather than a survey. At Rocktech Geoengineering Services, we are often called in after a borehole has already failed, and in most cases, the problem could have been avoided with proper surveying.

Step 1: “See” underground before you spend
Commission a hydrogeological survey. In Kenya, we typically use electrical resistivity, in which a controlled current is injected into the ground, and the response is measured. Different rocks, clays, and aquifers react differently to that current, so we can build a picture of what lies below the surface.
A good survey helps you:
a) Pick the best site on your land
b) Estimate the depth and thickness of water bearing zones.
c) Avoid dry or very low-yield areas, and flag zones likely to contain saline water.
The final hydrogeological report gives a specific recommendation: drill here, to approximately this depth, with this expected yield. That is a far better basis for investment than guesswork.

Step 2: Get the right permits before drilling
In Kenya, all boreholes require authorization from the Water Resources Authority (WRA) under the Water Act 2016 and the Water Resources Regulations 2023. Drilling without permits can attract penalties, including fines and possible closure of the borehole.
a) Submit the survey report, ID, and land ownership documents to WRA.
b) WRA reviews the application, may visit the site, and if satisfied, issues an authorization letter allowing you to construct (drill) the borehole at the specified location and depth range.

After drilling, apply for a water abstraction permit
a) After drilling, a Borehole Completion Record, pumping test data, and water quality report are prepared.
b) These documents are submitted to WRA to get a groundwater abstraction permit, which legally allows you to use the borehole and sets your allowable yield and annual fees.

Skipping these steps might look cheaper in the short term, but it exposes you to a higher risk of drilling a dry/poor yield borehole and to legal issues later when you try to connect the borehole to formal projects or sell the property.

At Rocktech Geoengineering Services, we support you through the entire journey:
i. Professional hydrogeological surveys to choose the best site and depth.
ii. Preparation of the hydrogeological report and guidance through WRA requirements.
iii. Technical oversight during drilling, test pumping, and water quality assessment.

If you are planning a borehole for your home, farm, institution, or real estate project in Kenya, we can help you design a borehole plan that makes sense technically, legally, and financially.

Engineering Solar Pumping Systems That Work with Your Borehole
Solar pumping can dramatically cut operating costs, but only when the system is designed from sound test pumping data.
At Rocktech Geoengineering, we integrate borehole and solar design into one coherent package:
1. Data driven system sizing- We use borehole construction details and test pumping data (dynamic water levels, yield, required head and daily demand) to size pumps, solar arrays and storage correctly.
2. Optimized capex and lifecycle opex- We balance pump and panel sizes against your usage profile to minimize lifecycle costs while maintaining a reliable supply.
3. Integration with existing infrastructure- Our designs consider existing storage, reticulation and backup power options so installations are seamless.
4. Technical supervision- We can supervise installation to ensure the as built system matches the design and manufacturer requirements.
If you plan to solarize a new or existing borehole, contact Rocktech geoengineering Services Ltd for an engineering grade solar pumping design based on real borehole data.

Turning Boreholes into Engineered Groundwater Assets
Many water projects still treat borehole drilling as a one off activity instead of an engineered groundwater asset. The result is short lived boreholes, poor data and higher lifecycle costs.
At Rocktech Geoengineering, we design boreholes to match the aquifer and the project:
1. Hydrogeological investigations before siting
We analyze geology, existing boreholes and expected yields to select sites with realistic performance and clear drilling targets.
2. Regulatory compliant designs and documentation
Our designs and reports support WRA licensing, NEMA approvals and county requirements.
3. Construction supervision and Quality Assurance
We design and supervise casing, screen selection, gravel pack, and grouting to protect the aquifer and deliver the design life you expect.
4. Data for future infrastructure decisions
Accurate drilling logs and hydrogeological interpretations provide a solid base for future storage, reticulation and expansion.
If you are planning a borehole, contact Rocktech Geoengineering Services Ltd to Survey, design, and supervise it as an engineered asset.
