Wellpoint Installation Durban

Wellpoint Installation Durban covers shallow groundwater systems for properties across the metro: the wellpoint itself, the pump that lifts the water, the controller that switches it, and the irrigation, storage or filtration it feeds.

A wellpoint is a small-diameter point jetted into water-bearing sand, usually somewhere between 6 and 12 metres down, with a surface-mounted suction pump above it. It is the cheapest practical way to get off the municipal meter for garden water, and it goes in inside a morning rather than over a week.

What a Wellpoint Installation Involves

Site and suitability assessment

The installer looks at what is likely to be under the property, where the pump can sit relative to power and the irrigation system, and whether there is jetting access. Ground with a high clay or stone content can stop the process before water is reached, which is why a no-water fee is quoted up front.

Jetting the point

High-pressure water is pushed down through galvanised steel pipes to open a hole into the sand. Once the water-bearing layer is reached, an LDPE riser with a filter screen is fed inside and the steel pipe is withdrawn, leaving the point in the formation.

Pump, controller and connection

A self-priming jet pump, typically 0.75kW to 1.5kW on domestic sites, is mounted at the surface with a non-return valve. From there the system is either left on a garden outlet or wired into a pump controller, a pressure tank, an irrigation manifold or a storage tank.

Testing and handover

Flow is measured, the pump is set and the system is run long enough to clear the fines that come through on a new point. Water quality is worth testing at this stage, before anything is plumbed into filtration or irrigation.

Wellpoint vs Borehole

A wellpoint is the right answer on the sandy coastal and Berea ground and the wrong answer where the ground turns to tillite, sandstone or shale within a few metres. That is the single question a site assessment is there to settle.

Durban Groundwater Conditions

Wellpoints work here because the older parts of the city sit on sand. The Berea Formation red sands cap the ridge through Berea, Glenwood, Morningside and Sherwood and carry on north through Durban North, La Lucia and Umhlanga, and the dune sand of the Bluff and the coastal strip north and south of the city is jettable ground for the same reason.

What does not follow is that any given erf has water. Ground conditions change over short distances, and two houses on the same street can return completely different results. Clay lenses, weathered rock, buried rubble and stone all stop a jetting rig, and the inland ground through Westville, Pinetown, Queensburgh and the Upper Highway sits on Natal Group sandstone, Dwyka tillite and shale, which is a borehole proposition rather than a wellpoint one.

Seasonality matters as much as geology. Durban gets its rain in summer, the water table recovers through the wet months from about October to March, and it draws down through the dry winter and into spring, which is exactly when the garden is under the most stress. A point set well into the saturated layer rides that swing; a marginal one does not.

What the Water Is Good For

• Garden and lawn irrigation. The main use, and the one that makes the numbers work, since outdoor watering is a large share of a typical household's consumption.
• Automated irrigation. With a controller and adequate flow, a wellpoint can run zoned sprinklers and drip lines without touching the municipal supply.
• Pool top-ups. Common, but depends on water quality: iron-bearing water will stain plaster and fittings.
• Storage tanks. Filling a buffer tank slowly and drawing from it evens out a modest yield.
• Washing and outdoor cleaning. Vehicles, paving and equipment.

Drinking, cooking and washing are a different matter. Shallow groundwater sits close to surface contamination sources and needs laboratory testing before anyone treats it as potable. Under the municipal Water By-law a groundwater system also may not be interconnected with the municipal water installation.

Registration and Water Rules

eThekwini requires groundwater abstraction points on a property to be registered with the municipality once installed, and the responsibility for obtaining permission sits with the property owner rather than the contractor. National guidelines gazetted in 2018 require groundwater abstraction to be metered, with records kept and available for inspection. Municipal requirements change, and properties in Ballito, Stanger, Scottburgh and Pietermaritzburg fall under different councils entirely, so confirm the position with the relevant municipality before you commit.

What to Check Before Appointing Anyone

• What is charged if no usable water is struck, and how is that decided?
• Is the pump included, and at what size and make?
• Who does the electrical connection, and is it in the price?
• Is the measured yield reported to you in litres per hour?
• Does the quote cover connecting to the existing irrigation system?
• What guarantee applies to the point, the pump and the workmanship?
• Will they handle the municipality application and registration paperwork?

Areas Covered

Quotes are arranged across the Berea suburbs of Glenwood, Morningside and Sherwood, north through Durban North, La Lucia, Umhlanga, Umdloti, Ballito and Stanger, south through the Bluff, Amanzimtoti, Kingsburgh, Warner Beach and Scottburgh, west through Westville, Pinetown, New Germany, Queensburgh, Malvern and Chatsworth, up the Upper Highway through Hillcrest, Kloof, Waterfall, Gillitts and Botha's Hill, and inland to Pietermaritzburg.
