Borehole Drilling
Milnerton

Milnerton sits on sandy coastal ground with a shallow water table, which means water is usually available and the real questions are quality and volume.

Iron staining is the routine complaint, salinity is a genuine possibility near the shoreline, and a wellpoint covers garden irrigation on many properties without needing a borehole at all.

What Is Under Milnerton

Formation	Where it sits	What it means for drilling
Coastal and windblown sand	Across most of the area	Unconsolidated and permeable with a shallow water table. Wellpoints work; boreholes need screening and a gravel pack rather than open hole.
Alluvium and vlei deposits	Around Rietvlei and the Diep River corridor	Shallow water with significant surface influence. Quality needs careful attention here.
Basement rock	At depth below the sand	Rarely the target, since the sand above is more accessible and more productive.

What That Means for Your Borehole

• Finding water is usually not the problem; quality and sustainable volume are.
• A wellpoint often covers garden irrigation at a small fraction of borehole cost.
• Iron and manganese staining is the common complaint, treatable but only once measured.
• Surface influence is real near Rietvlei and the Diep River, where shallow water sits under developed and low-lying ground.

What to Watch For Here

Iron and manganese. The routine issue in this ground. Water arrives clear, oxidises on contact with air and stains laundry, paving, sanitaryware and pool surfaces. Treatable with oxidation and filtration specified from measured concentrations - see filtration.

Surface influence near Rietvlei and the Diep River. Shallow water beneath low-lying developed ground is exposed to stormwater, sewer infrastructure and general urban runoff. Microbiological testing is essential before any indoor use, and a proper sanitary seal at the headworks matters more here than in deep hard-rock settings.

Older suburbs, established gardens, industrial neighbours. The mature parts of Milnerton carry far larger irrigated areas than the newer coastal developments, which pushes demand up and usually brings storage into the design. On the industrial side toward Montague Gardens and Paarden Eiland, historic land use is a genuine reason to widen the analysis beyond the standard domestic panel before putting the water anywhere near people.

What the Water Is Used For

• Garden and lawn irrigation, the dominant use
• Complex and estate communal landscaping
• Pool top-up, usually after iron treatment
• Toilet flushing and laundry on separated plumbing
• Commercial and industrial washdown in Montague Gardens and Paarden Eiland
• Standby supply during municipal interruptions

Wellpoint or Borehole?

Viable across much of Milnerton, and often the sensible choice. Sandy ground with a shallow water table is what a driven or jetted point needs, and for garden irrigation it usually suffices at a small fraction of borehole cost. A borehole is worth it where you need more volume, better seasonal reliability, or water that can be properly sealed against the surface contamination shallow points cannot exclude.

Registration and Abstraction

Boreholes and wellpoints here must be registered with the City of Cape Town. Separately, the National Water Act governs how much you may abstract: reasonable domestic use and small-scale garden watering generally fall under Schedule 1, while larger abstraction may require registration or a water use authorisation from the Department of Water and Sanitation. Requirements change, so confirm your position before drilling.

Borehole Prices in This Area

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	R400 - R900 /m	Coastal sand drills quickly, keeping per-metre rates at the lower end.
uPVC casing, installed, per metre	R400 - R700 /m	Diameter and class. Weathered-zone thickness is not known until drilling starts.
Mobilisation and site establishment	R2,500 - R9,000	Flat and accessible. Iron treatment is the item most often needed and most often forgotten.
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.
Wellpoint alternative	R6,500 - R10,000	Where sand depth and a shallow water table allow it, this covers garden irrigation for a fraction of the cost.
Typical complete project	R50,000 - R140,000+	Everything above, excluding treatment, which depends entirely on the water analysis.
