Borehole Drilling
Westville

Westville is typically sandstone country. The reddish, quartz-rich Natal Group sandstone that forms the cliffs of the Palmiet River gorge runs under much of the suburb, with Dwyka tillite and dolerite in places. Water is held in joints and fractures rather than in the rock mass, so siting a hole on a fracture matters more than drilling deep.

The suburb is known for big, established stands under tall indigenous and exotic trees, many on sloping ground falling towards the Palmiet. That leafy character is what shapes most jobs here: getting a rig past mature trees, garden walls and paved driveways without damage takes as much planning as the drilling itself.

What Is Under Westville

Formation	Where it sits	What it means for drilling
Natal Group sandstone	Under much of Westville and exposed in the cliffs of the Palmiet River valley	Hard, abrasive and slow to drill when fresh. Water comes from joints and faults, so a survey aims to cross a fracture zone rather than chase depth.
Dwyka tillite	Patches on the lower ground and towards the Pinetown side, depending on the stand	Drills steadily and weathers to a clayey cover that needs casing. Yields can be poor, so a sandstone site is usually preferred where there is a choice.
Dolerite dykes and sills	Intrusions cutting both rock types, often marked by changes in soil colour and vegetation	Fresh dolerite is very hard, but the cracked contact zone beside it is a common water target in this area.

What That Means for Your Borehole

• Siting beats depth because a hole that misses the fractures in sandstone can stay dry however far it goes.
• The water is usually soft and often of reasonable quality, though it can be slightly acidic and carry iron or manganese.
• Drilling is slower than on the coast so allow more rig time on fresh sandstone than on the sandy coastal belt.

What to Watch For Here

Old trees decide where the rig can go. Westville's mature canopy is one of its best features, but large roots, overhanging branches and protected trees limit both the access route and the drilling spot. We walk the property first, look for a path that avoids root zones and low limbs, and sometimes use a smaller rig rather than force a big one through a garden.

Soft sandstone water can be aggressive. Water from quartz-rich sandstone is often low in minerals and slightly acidic. Over time that can corrode copper pipes and steel fittings and leave blue-green or brown stains. A water test shows whether a simple pH correction or iron filter is worth adding before it reaches the house.

What the Water Is Used For

• Irrigating large shaded gardens and lawns on Westville North stands
• Keeping indigenous gardens alive through the drier winter months
• Standby water during supply interruptions on the western side of eThekwini
• Topping up pools on larger family properties near Dawncliffe
• Feeding toilets and outside taps through a separate borehole line

Wellpoint or Borehole?

Rarely. Most of Westville sits on hard sandstone or tillite with only a thin soil cover, and the water table on the slopes is usually well below suction depth. A narrow strip of alluvium beside the Palmiet or a stream might allow a driven point, but for nearly every property here a drilled borehole is the practical route.

Approval and Abstraction

Westville falls under eThekwini Metropolitan Municipality. Municipal requirements differ across KwaZulu-Natal. eThekwini is reported to require a borehole to be registered with the municipality once drilling is complete, and its Water By-law prohibits any connection between a borehole system and the municipal supply unless backflow is prevented. Msunduzi, KwaDukuza and Umdoni set their own requirements, so confirm the current position with the municipality before the rig arrives. Separately, the National Water Act governs how much you may abstract: reasonable domestic use generally falls under Schedule 1, and in 2026 the Department of Water and Sanitation confirmed that households using borehole water for reasonable, non-commercial domestic purposes do not need to register nationally. Commercial, agricultural and larger abstraction may need registration or a water use authorisation, and draft national groundwater regulations published for comment in December 2025 may add obligations once finalised. Rules change, so confirm the current 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	R500 - R1,200 /m	Fresh Natal Group sandstone and dolerite are hard and wear bits; tillite drills more steadily. The mix your hole meets decides where the rate lands.
uPVC casing, installed, per metre	R400 - R700 /m	Casing covers the weathered top and any clayey tillite. In hard sandstone the cased length is often short.
Mobilisation and site establishment	R2,500 - R9,000	Slopes, gorge-side stands and access through older suburbs move this; a site visit settles it.
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	R60,000 - R190,000+	Everything above, excluding treatment, which depends entirely on the water analysis.
