Borehole Installers Kenton-on-Sea | Boorgate Kenton-on-Sea

Kenton-on-Sea sits between the Bushmans and Kariega river mouths on Alexandria Formation ground under a thick cover of coastal and dune sand.

Shallow, workable holes by Eastern Cape standards, with salinity rather than depth as the main constraint.

What Is Under Kenton-on-Sea

The formations below are what a rig actually meets on a Kenton-on-Sea property, and between them they govern the depth, the casing requirement and what the hole will realistically give you.

Formation	Where it sits	What it means for drilling
Alexandria and Nanaga Formations	The coastal terraces and palaeodunes from Alexandria to Port Alfred	Semi-consolidated to consolidated calcareous sandstone, coquinite and aeolianite with calcrete. Intergranular and fracture flow combined, and the basal conglomerate yields only low to fair quantities.
Kirkwood and Sundays River Formations	The Sundays River valley through Kirkwood and Addo	Reddish mudstone and impermeable mudstone with sandstone lenses. Acts largely as an aquiclude, and the water in it is frequently salty.
Schelm Hoek dune sand and estuarine sand	The dune cordon and the river mouths at Port Alfred, Kenton and Boknes	Genuinely unconsolidated and shallow, which makes it the one wellpoint target here. Brackish more often than not.

What That Means for Your Borehole

Brackish is the normal result on this coast, not the exception, and it is why Kenton, Bushman's and Alexandria all run on reverse osmosis rather than on borehole water alone. Plan around treatment or around non-potable use.
The deeper Table Mountain Group is the good water, and in the Sundays River valley it supports substantial citrus and lucerne irrigation. That is a deeper and more expensive hole than one stopping in the Uitenhage Group.
Calcareous ground means hardness, because limestone, coquina and calcrete all contribute. It is manageable, but it belongs in the budget for fittings and treatment.

Where We Work Around Kenton-on-Sea

Holiday homes and second properties
Smallholdings on the inland side

What to Watch For Here

Two tidal river mouths flank the village, so salinity risk depends heavily on exactly where you are rather than on a village-wide rule.

Sandy ground needs screened casing and a gravel pack, not plain casing. That specification is where quotes genuinely differ here.

What the Water Is Used For

Irrigating coastal gardens and lawn
Rinsing salt off paving, walls and vehicles
Pool top-up, subject to what the analysis says
Standby supply through restrictions and outages
Keeping mature planting alive through summer

Wellpoint or Borehole?

Only on the dune cordon and the estuarine sand at the river mouths, and the water there is commonly brackish. The Alexandria, Nanaga and Bathurst Formations are consolidated and cannot take a driven point, which is worth saying plainly because they look like sand.

Water Quality in Kenton-on-Sea

Brackish water is the defining local issue. Uitenhage Group boreholes are generally unsuitable for domestic or irrigation use without treatment, and the Sundays River Formation carries very salty, probably connate water. Hardness is predictable in the calcareous Algoa Group. On cultivated ground, nitrate from fertiliser belongs on the analysis.

A water analysis is what turns that from a general expectation into a number for your specific hole, and treatment should be specified against the result rather than against the area's reputation.

Registration and Abstraction

Groundwater itself is regulated nationally rather than municipally, and we could not find a published borehole by-law for this district municipality. As the water services authority it can still require approval before a property draws on an alternative supply, so we confirm the local position before drilling rather than assuming it. Separately, the National Water Act governs how much you may abstract. Reasonable domestic use and small-scale garden watering generally fall under Schedule 1 and need no licence or registration, but taking more than 10 cubic metres a day from groundwater on a property must be registered, and irrigation or commercial volumes usually require registration or a water use authorisation from the Department of Water and Sanitation.

Borehole Prices in Kenton-on-Sea

Drilling is charged per metre, so depth drives the total. The ranges below are framed for local ground conditions and access.

Item	Indicative range	What moves it locally
Drilling, per metre	R450 - R1,000 /m	Shallow coastal and Uitenhage Group holes drill quickly. A deeper hole targeting the Table Mountain Group is a different cost altogether.
uPVC casing, installed, per metre	R420 - R780 /m	Screening and gravel pack through semi-consolidated sand, and casing through the weathered mudstone section.
Mobilisation and site establishment	R2,500 - R11,000	Access, distance and site conditions move this; a site visit settles it before quoting.
Water survey	R5,000 - R12,000	Targets structure rather than depth. Worth most where yield is fracture-dependent.
Yield testing	R3,500 - R15,000	Establishes the sustainable rate that pump selection depends on.
Pump, supplied and installed	R15,000 - R45,000	Greater depth means more head, which means a larger pump and heavier cable.
Storage and booster	R12,000 - R35,000	Needed wherever peak demand exceeds the borehole's sustainable rate.
Typical complete project	R65,000 - R180,000+	Everything above, excluding treatment, which depends entirely on the water analysis.

These are indicative ranges, not a quotation. They are compiled from published South African supplier and contractor pricing to give you a starting point for budgeting. They are not our rate card, and no figure here is a commitment.

Treat them as a broad guide only. Published borehole pricing in South Africa varies enormously - different 2026 guides quote per-metre drilling rates for the same province that differ by a factor of three - because depth, geology, access, specification, distance and fuel costs all move the number. Depth in particular is not known until the hole is finished. Figures generally exclude VAT unless noted, and change over time. Only an itemised written quote against your actual site means anything.

Kenton-on-Sea Borehole FAQs

Is Kenton-on-Sea good borehole ground?

Modest, and worth being straight about. The village's own supply wells are shallow and brackish, each contributing a small fraction of daily demand, with the bulk of the town's water coming from a desalination plant.

A private hole can still earn its place for irrigation and washdown. Treating it as a drinking-water solution without an analysis would be a mistake here.

Do I need a borehole for a holiday house here?

It depends on what the garden needs while you are away and how reliable your supply is through season peaks, when the village population multiplies.

A tank buys you more than a bigger pump does on an irregularly used property.

Will borehole water at Kenton-on-Sea be salty?

Frequently, yes, and it is worth hearing that before you drill rather than after. This coast is dominated by brackish groundwater, which is precisely why the local municipal schemes depend on reverse osmosis.

That does not make a borehole pointless. It makes the water analysis the step that decides what you can use it for, and it often means irrigation and washdown rather than drinking.

Can a Kenton-on-Sea property irrigate from a borehole?

It depends entirely on the analysis, because salinity and sodium matter more to soil structure and to trees than they do to a lawn.

The deeper Table Mountain Group water in the Sundays River valley does support large citrus and lucerne irrigation, so good water exists here. It is usually deeper than people expect.
