Milnerton borehole drilling: compare three quotes

Local considerations in Milnerton

The Cape Flats aquifer is described as a shallow aquifer in coastal sand that stretches from False Bay to the Tygerberg hills and to Milnerton, lying over Malmesbury shale. That means groundwater is often close to the surface, and it also means the sand must be properly supported: casing and screens keep a borehole from filling with sand. A United Nations assessment describes the Cape Flats aquifer as highly vulnerable to pollution from land use, including industrial areas and landfills. With the Diep River lagoon, the Rietvlei wetland and industrial zones such as Montague Gardens nearby, it is sensible to ask installers where they would site a borehole relative to drains, sewers and any fuel storage. Complexes and gated estates may need trustee or association consent. The City requires written notice before drilling, registration, metering and a sign.

Pricing guidance

There is no single national price for a borehole. Cost is driven by drilling depth, rock type, the casing needed, rig access and travel distance, plus the pump, storage and electrical work that make the water usable. As a reference point, complete residential projects in Johannesburg typically range from about R40,000 to R150,000; Cape Town quotes can land above or below that depending on local depth and geology. Compare complete-system quotes, never drilling-only prices.

Typical Milnerton scenarios

• A Milnerton homeowner near the lagoon asks installers how far a new borehole should be from the sewer line and stormwater drain. (Illustrative example.)
• A sectional-title complex in Milnerton wants a shared irrigation borehole and needs consistent quotes to present to its trustees. (Illustrative example.)

What installation involves

1. Site assessment and, where appropriate, geophysical survey
2. Drilling position agreed; rig access confirmed
3. Drilling and casing to water-bearing depth
4. Yield test to establish delivery
5. Pump selection and installation
6. Storage, electrical and plumbing integration
7. Water test and commissioning with documentation

How to compare your Milnerton quotes

• Compare complete-system quotes, never drilling-only
• Ask how rock and extra depth are priced
• Confirm casing specification and included depth
• Check yield testing and water testing are included
• Ask for recent reference sites nearby
• Confirm pump brand, warranty and service costs
• Ask what you pay if yield disappoints
