A borehole on its own is only half a water supply. What turns it into running water is the pump matched to the depth and yield, storage that carries you through an outage, and a pressure system that gives you a proper shower upstairs. We install and maintain all of it.

Borehole pump installation

Pump selection is where most water systems are won or lost. Too small and it never fills the tank. Too large and it draws the borehole down, runs dry and burns out. The right choice comes from the depth, static water level and yield, plus the head and distance it has to push against.

Submersible pumps supplied, installed and set to depth
Pump sizing against yield, head and daily demand
Rising main, cable, safety rope and headworks
Control boxes, dry run protection and level control
Pump removal, testing, repair and replacement
Assessment and fault finding on existing installations

Dry run protection matters. The most common cause of a dead borehole pump in Harare is running it against an empty borehole. Protection costs a fraction of a replacement pump, so we fit it as standard.

Storage and reservoir tanks

Storage is what makes a water supply reliable. It lets the pump work in short efficient runs, carries you through a power outage or a borehole recovery period, and when elevated it delivers water by gravity with no pump running at all.

Reservoir and storage tanks supplied and installed
Tank stands and elevated platforms
Multiple tank manifolds, balancing and isolation
Inlet, outlet, overflow, drain and float valve assemblies
Municipal backup storage with automatic switchover
Tank cleaning, repair and re-plumbing

Pressure tanks and booster pumps

Gravity from a low tank stand gives flow but not much pressure. A pressure tank and pump set gives consistent pressure at every outlet, and the pressure vessel stops the pump switching on and off every few seconds, which is what destroys pumps and pressure switches.

Pressure tank and pump sets sized and installed
Booster pumps for multi storey and long runs
Variable speed pumps for constant pressure
Pressure switch setting, bladder charging and commissioning
Non return valves, strainers and isolation
Diagnosis of short cycling, pressure loss and pump chatter

Solar borehole pumping

Where there is no reliable grid, or you simply do not want the pump on your electricity bill, a solar array can drive the pump through the day and fill elevated storage. No batteries, no fuel, and the tank does the work at night. See solar and battery storage for the electrical side.

Irrigation and reticulation

The same skills that get water to a house get it to a field. We install reticulation and irrigation for smallholdings, farms, greenhouses, nurseries and estates, fed from borehole and storage.

Mainline and sub-main installation
Manifolds, valve assemblies and zone control
Drip line layout and installation
Greenhouse and nursery irrigation
Filtration and pressure regulation
Estate and garden reticulation

Maintenance and callouts

Water systems are mechanical and they wear. Pressure switches drift, bladders lose charge, float valves stick and pumps eventually give up. We maintain and repair systems we installed and systems we did not.

No water, low pressure and pump not starting
Pump pull, inspection and reinstallation
Pressure system recommissioning
Leak tracing on buried reticulation
Scheduled maintenance for farms, estates and businesses

Borehole & Pump FAQs

Do you drill boreholes?

Our work starts once the hole is there. We install, commission and maintain the pump, rising main, storage, pressure system and reticulation, and we will advise on what your borehole's depth and yield mean for the equipment it needs.

My pump runs but the tank never fills. Why?

Usually one of four things. The borehole yield is lower than the pump's draw so it is running dry, the foot or non return valve is failing and letting water fall back, there is a leak in the rising main, or the pump has worn impellers. We test rather than guess, and we will tell you if the answer is a smaller pump rather than a bigger one.

Why does my pressure pump switch on and off constantly?

That is short cycling, and it is nearly always a pressure tank that has lost its air charge or has a failed bladder. It destroys pumps and pressure switches quickly. Recharging or replacing the vessel and resetting the switch normally solves it.

Can I run my borehole pump on solar?

Yes, and it is often the best value solar you can buy. A dedicated array drives the pump through the day and fills elevated storage, so you get water by gravity at night with no battery at all. Where you already have a hybrid system we can run the pump off it, but pumping into storage is usually cheaper.

Do you install irrigation for farms and greenhouses?

Yes. Mainlines, manifolds, valve assemblies, zone control and drip lines for field crops, greenhouses, nurseries and estates, fed from borehole and storage.
