Yesterday, our borehole survey team conducted a detailed geophysical groundwater investigation at Carrick Creagh Estate using the PQWT (Portable Quantum Water Detector) system.

The PQWT instrument operates on the principle of the Earth’s natural electromagnetic and telluric fields, using the Natural Electric Field Frequency Selection Method. This advanced hydrogeophysical technique does not introduce any artificial signal source; instead, it relies entirely on naturally occurring subsurface electrical variations.

How the system works:

1. Natural Signal Source
The system detects naturally generated electromagnetic fields originating from the Earth, solar activity, and atmospheric interactions.

2. Variation in Subsurface Conductivity
Different underground materials such as rock formations, fractures, and water-bearing zones exhibit varying levels of electrical resistivity and conductivity. These differences create measurable anomalies in the natural field response.

3. Data Acquisition
The instrument records potential differences across multiple frequencies along survey lines, capturing subsurface resistivity variations linked to geological structures.

4. Real-Time Interpretation & Imaging
The collected data is processed instantly to generate profile curves, cross-sectional models, and 3D subsurface visualizations, allowing for the identification of aquifers, fault zones, and potential voids.

Survey Outcome

A promising groundwater target was identified at Point 3 on the initial profile, which was later confirmed and refined during calibration, correlating strongly with Point 6 on the secondary profile interpretation. The anomaly indicates a potential fracture-controlled aquifer zone suitable for borehole development.

We are currently finalizing the drilling quotation and technical design, and our team will be returning to the site within the coming days to commence drilling operations.

Further updates from this project will be shared as work progresses.

After the rod flushing a high-yielding borehole was successfully intercepted at an alternative location within the same property in Glenluce. The borehole has demonstrated strong groundwater potential, making it suitable for supporting larger pumping systems, including 10 HP pumps and above, depending on the final yield and pumping test results.

Such boreholes provide an excellent foundation for commercial irrigation, livestock watering, and other high-demand water applications, unlocking significant development opportunities for the property.

We extend our congratulations to our client on securing access to this valuable groundwater resource and look forward to supporting the next stages of development.

We are pleased to announce the successful installation and commissioning of two Venturi fertigation units at Glenluce Farm, Norton, each designed to service a 500 m² greenhouse production unit.

As part of the upgrade, we also improved the existing irrigation infrastructure by installing 10 cm double-emitter drip tape, a modification aimed at enhancing water distribution uniformity and addressing the water deficit challenges that had been affecting crop performance within the greenhouses.

● Inadequate and uneven water application.
● Inefficient fertilizer utilization.
● High labour requirements during fertilizer and chemical application.
● Inconsistent crop response due to non-uniform nutrient distribution.

Through the integration of a Venturi-based fertigation and chemigation system, WaterFirst Agrisolutions has provided a practical and cost-effective solution that improves both irrigation and nutrient management efficiency.

𝐖𝐡𝐚𝐭 𝐢𝐬 𝐚 𝐕𝐞𝐧𝐭𝐮𝐫𝐢 𝐅𝐞𝐫𝐭𝐢𝐠𝐚𝐭𝐢𝐨𝐧 𝐒𝐲𝐬𝐭𝐞𝐦?

A Venturi injector is a hydraulic device that uses the pressure energy of flowing water to draw liquid fertilizers, nutrients, or agrochemicals into an irrigation system without the need for an external power source.

The technology enables the simultaneous application of water and nutrients directly to the crop root zone through the irrigation network, a practice commonly known as fertigation. When crop protection products are applied through the same system, the process is referred to as chemigation.

𝐊𝐞𝐲 𝐁𝐞𝐧𝐞𝐟𝐢𝐭𝐬 𝐨𝐟 𝐕𝐞𝐧𝐭𝐮𝐫𝐢 𝐅𝐞𝐫𝐭𝐢𝐠𝐚𝐭𝐢𝐨𝐧

1. Improved Fertilizer Use Efficiency
Nutrients are delivered directly to the active root zone where plants absorb them most effectively. This minimizes nutrient losses through runoff, evaporation, and deep percolation.

2. Reduced Labour Costs
The system eliminates the need for manual fertilizer application, reducing labour requirements and improving operational efficiency.

3. Enhanced Water Productivity
Water and nutrients are applied simultaneously, ensuring that crops receive both resources precisely when needed.

4. Uniform Nutrient Distribution
Every plant connected to the irrigation network receives a consistent nutrient concentration, resulting in more uniform crop growth and improved yields.

5. Cost-Effective Technology
Venturi injectors operate using existing water pressure and require no electrical power, making them one of the most economical fertigation solutions available.

6. Flexible Chemical Application
The system can also be used to inject approved soluble agrochemicals, allowing growers to carry out chemigation operations efficiently.

𝐓𝐡𝐞 𝐒𝐜𝐢𝐞𝐧𝐜𝐞 𝐁𝐞𝐡𝐢𝐧𝐝 𝐭𝐡𝐞 𝐕𝐞𝐧𝐭𝐮𝐫𝐢 𝐄𝐟𝐟𝐞𝐜𝐭

The Venturi injector operates on the principles of fluid dynamics, specifically the Continuity Equation and Bernoulli's Principle.

When water passes through the narrowed throat of the Venturi injector:

1. The flow area decreases.
2. Water velocity increases.
3. Fluid pressure drops significantly within the constricted section.
4. A pressure differential is created between the injector throat and the fertilizer tank.
5. The pressure difference generates a suction force that draws fertilizer or chemical solution into the irrigation water stream.

The injected solution is then carried through the drip irrigation network and delivered directly to the crop root zone.

In simple terms, the system uses the energy of moving water to automatically "pull" fertilizer into the irrigation line without requiring a pump.

Drip irrigation is one of the most efficient irrigation methods available because it applies water directly to the root zone with minimal losses. When combined with Venturi fertigation:

• Water application efficiency improves.
• Nutrient use efficiency increases.
• Fertilizer wastage is minimized.
• Crop growth becomes more uniform.
• Production costs are reduced.
• Yield potential is enhanced.

This combination is increasingly becoming the preferred irrigation strategy for greenhouse production, horticulture, and high-value crops.

We recently carried out rod flushing on a collapsed borehole that was originally drilled to a depth of 45 m. Investigations suggest that improper casing installation may have resulted in casing separation during the first drilling, leading to progressive silt accumulation within the borehole.

Over time, the borehole became heavily silted, eventually trapping and damaging the pump. Approximately 27 m of the lower section had become blocked by sediment.

As part of the rehabilitation process, we conducted rod flushing to remove the accumulated silt and restore the borehole. The operation successfully recovered 30 m of usable depth, improving the borehole's condition and providing valuable information for the next stage of remedial works. The farmer has already lost the other 15m.

Proper borehole construction and casing installation are critical for ensuring long-term borehole performance and reliability. Deepening a hole installed with small casings is very difficult as the drilling bit cannot fit in the casings. Rod flushing doesn't have a guaranteed success and its a 50/50 probability of winning or loosing. We strongly advise clients to do it right at first.

Rod flushing is the blowing of the borehole using the drilling rig and drilling rods. Its more powerful and effective on resuscitating heavily silted or collapsed boreholes. The alternative flushing method is the one that uses a poly pipe and a compressor to blow out silt out of the borehole. We term it poly pipe flushing and is less effective for heavily silted boreholes.

Client’s experiencing similar problems of borehole collapse, trapped pumps, silted boreholes and clogged boreholes should conduct us for an assessment on 078 764 8966

The borehole was drilled at Peg 6, a location that had been identified during the geophysical survey as having an average probability of intercepting groundwater. The target was associated with a fracture zone indicated by contour convergence; however, the anomaly was not well confined or strongly bounded, leading to its classification as an average to low-yielding target.

Survey interpretation indicated that the fracture exhibited its highest conductivity within the upper 15 m, as evidenced by the steep contour convergence and the presence of low-resistivity (blue-coloured) zones, characteristic of soft, unconsolidated overburden materials. The conductivity and inferred saturation decreased significantly with depth, suggesting that any groundwater encountered would likely be associated with shallow weathered formations and perched aquifer conditions rather than a deep, productive fractured aquifer.

Drilling progressed smoothly to the planned termination depth of 70 m, with conditions encountered largely consistent with the survey interpretation. The first 12 m were drilled using a commercial cutting bit through the unconsolidated overburden, after which drilling continued with a standard 140 mm down-the-hole (DTH) bit to the final depth.

Three principal geological units were encountered:

0–5 m: Wet, coarse-grained gravel.

5–10 m: Fine-textured sandy formation.

12–70 m: Predominantly competent granitic bedrock.

Moisture content within the drill cuttings progressively decreased with depth, and by approximately 25 m, the formation had become largely dry. Drilling was dominated by whitish-grey granitic dust, with only a few minor fractures intercepted throughout the borehole profile.

At 60 m, drilling was temporarily halted for approximately 30 minutes to allow for borehole recovery and assessment of groundwater inflows. Following flushing, only limited wet cuttings were observed, indicating minimal water contribution from the intercepted fractures. Drilling was then extended by an additional 10 m to a final depth of 70 m, after which the borehole was terminated.

The borehole was fully cased to the bottom using 140 mm Class 6 uPVC casing, with double casing installed through the first 12 m to stabilize the unconsolidated overburden section.

Conclusion

The drilling results confirmed the pre-drilling interpretation. The borehole is classified as a low-yielding borehole, performing below average expectations. Groundwater production is expected to be derived primarily from the shallow weathered zone and minor fractures encountered in the upper section of the profile. The granitic bedrock intercepted at depth is generally tight and exhibits limited groundwater storage and transmissivity.

While some improvement in yield may occur over time as the borehole develops and fractures are gradually cleaned, no significant increase in productivity is anticipated.

Recommendation

The borehole is suitable for domestic water supply purposes only. We recommend installation of a 1 HP borehole pump operating at a low abstraction rate and equipped with dry-run protection to safeguard the pumping system against water-level fluctuations.

Today, we successfully conducted a borehole survey in Kaviya Village, Chiweshe, for a client seeking a reliable groundwater source.

Travelling along the Glendale–Chiweshe Road, we turned at the Howard turn-off, proceeded for several kilometres, and then took the second left turn at Godzi Township to reach the site.

The survey area is located close to Mwenje Dam, which is fed by the Sawi River. The site is characterized by white sandy soils, typical of granitic geology, with a prominent dwala (granite outcrop) located approximately one kilometre from the survey point.

From a hydrogeological perspective, granite is generally a hard, competent, and relatively impermeable rock formation. As a result, groundwater does not typically occur within the rock mass itself. Instead, groundwater occurrence is largely controlled by secondary geological structures such as fractures, cracks, joints, weathered zones, and conductive fault systems, which create pathways and storage spaces for water.

Having established that the area is underlain by granitic formations, our survey focused on identifying these favourable subsurface features that are most likely to host and transmit groundwater. Locating such structurally controlled targets is essential for improving drilling success rates and achieving sustainable borehole yields.

This project forms part of our ongoing commitment to helping farmers, communities, and institutions secure dependable water sources for domestic use, livestock, irrigation, and long-term agricultural development. Within a space of 2 to 3 days we going back to drill this point.

Stay tuned for more updates as we continue serving clients across Zimbabwe. 💧🌱🚜
