Service · Borehole pumpsSolar borehole pumps & submersible pumps.

A borehole needs the right pump to be useful. We install solar-driven and electric submersible borehole pumps across Durban and KZN, sized to your borehole’s depth and yield, so water keeps flowing when the power doesn’t.

Submersible borehole pump being installed by the Ekhaya Projects team

01

Who it’s for

Homeowners who want water through power outages and load-shedding. Farms and smallholdings far from a reliable supply. Developments and businesses that want lower running costs. And anyone with an existing borehole whose pump has given up.

02

Solar or electric?

Both are submersible pumps that sit down in the borehole. The difference is where the power comes from.

  • Solar borehole pump

    Runs straight off solar panels through a controller, so it pumps whenever the sun is up, with no electricity bill and no dependence on the grid. Best paired with a tank that stores the day’s water for the evening.

  • Electric submersible pump

    Runs off your mains supply and pumps on demand, day or night. Simple and powerful, but it stops when the power does, unless it’s connected to an inverter or backup.

  • Hybrid set-ups

    Some properties run an electric pump with a solar inverter connection, so the pump keeps going through outages. Kelvin will tell you whether that suits your borehole and budget.

How we install a borehole pump

  1. 01

    Check the borehole

    We look at the depth, water level and yield. A yield test tells us how much water the borehole can safely give, so the pump never runs it dry.

  2. 02

    Size the pump

    The pump has to lift water from deep in the borehole up to your tank or house. We choose one that matches that lift and your daily water needs, and for solar, the panel array to drive it.

  3. 03

    Install and wire

    The pump is lowered on its rising main (HDPE pipe), safety rope and submersible cable. For solar, the panels go near the borehole head or on a roof and feed an MPPT solar pump controller with dry-run protection. Electric pumps are matched by kW rating to the depth and lift.

  4. 04

    Connect and test

    We connect the pump to your JoJo tank or booster system, with a float switch in the tank so the pump stops when it’s full and starts again as it drops, then run it and check the flow before we leave.

Questions, answered

Common questions

Will a solar borehole pump work during load-shedding?

Yes. A solar pump runs off its own panels, not the grid, so load-shedding doesn’t stop it while the sun is up. It pumps into a tank during the day, and the tank supplies you in the evening. If your house pressure comes from a booster pump on the tank, that pump does need power, so ask Kelvin about running it off backup.

Does a solar pump work on cloudy days?

It pumps less when the light is weak, and not at night. That’s why we pair solar pumps with storage: a tank sized to carry you through the evening and duller days.

Where do the solar panels go?

Near the borehole head or on a roof: wherever they get the most sun with a sensible cable run to the pump controller. Kelvin picks the spot with you at the site survey.

What stops a solar pump running the borehole dry?

The MPPT solar pump controller has dry-run protection, which stops the pump if the water level in the borehole drops too low. A float switch in the tank stops it when the tank is full.

Can you replace the pump in my existing borehole?

Yes. If an existing pump has failed or was never sized properly, we can check the borehole and fit a new solar or electric submersible pump. If the borehole itself is the problem, see borehole repairs.

How do I know what size pump I need?

It depends on how deep the water is, how far and how high it has to be pumped, how much water the borehole can give, and how much you use. Kelvin works that out at the site survey, so you don’t pay for a pump bigger than your borehole can feed.
