What pushes the price of borehole tank installation up

Raised steel stand height, from 3 m up to 4.5 m
Tank size and material: poly, pressed steel or concrete
Booster pump, pressure vessel and float-switch controls

Types of borehole tank installation

Type	Best for	Keep in mind
Vertical poly tank on ground base	Most homes with a booster pump	Needs a pump for household pressure
Poly tank on raised stand	Gravity pressure without a booster pump	Steel stand adds about R13 000 or more
Horizontal or slimline tank	Tight spots under decks or eaves	Costs far more per litre than vertical
Underground tank	Hidden storage where space is tight	Hard and costly to replace later
Pressed steel tank	Large volumes for farms and irrigation	Costs more than poly tanks

Borehole tank installation materials and specs compared

Material	Strengths	Watch out for
UV-stabilised food-grade poly (LLDPE)	Rustproof, seamless, 10-year warranty common	Hard impact can crack it
SANS 1731:2017 tank standard	Shows the tank meets the national standard	Cheap tanks may skip UV stabilisation
Primed or galvanised steel stand	Engineer-designed, 10-year guarantee on some kits	Galvanised costs about 15% more
Pressed steel tank	Lasts 20+ years, closed so algae-resistant	Higher price than poly
Concrete tank	Lasts 20–30 years, often buried	Bare concrete leaches lime; lining advised
Level compacted or concrete base	Spreads the load of a full tank	Bare soil sinks and tilts

Base and stand

Every 1 000L of water weighs roughly 1 tonne.
Ask for a level, compacted base or reinforced concrete slab.
Never place one tank half on concrete and half on soil.
Route overflow water away so it cannot wash out the base.

Pump, float and pressure

A float switch stops the borehole pump when the tank is full.
A low-level cut-out stops the booster pump running dry.
Ground-level tanks need a booster pump for usable household pressure.
Ask for a non-return valve so water cannot drain back down.

Size and water quality

Plan on about 200 litres per person per day.
A low-yield borehole can still cope with a big enough tank.
Choose a light-blocking tank with a fitted lid to limit algae.
Drain and rinse the tank every few years to clear sediment.

Approval for borehole tank installation

Boreholes using over 10 000 litres a day need national registration.
Ask your municipality's building control about plumbing approval and tall stands.
Tanks fed by municipal water need an air gap; use SABS-approved fittings.

Borehole tank installation services

Service	What to ask for
Poly tank supply and fitting	Quote tank, base, plumbing and delivery separately
Raised tank stand build	Stand height, steel finish and guarantee
Float switch and pump control	Dry-run protection and overflow cut-off
Booster pump and pressure set-up	Pump flow rate and pressure rating
Tank base preparation	Level compacted pad or reinforced slab
Tank replacement or relocation	Old tank removal and pipe reconnection

Practical borehole tank installation tips

Size the tank to hold at least 2 days of demand.
A 2 500L tank gives about 3 to 4 days for four people.
Set the pump shut-off float at least 15 cm below the overflow.
Leave 300 mm around the tank for inspection access.
Test borehole water before drinking it; budget R2 000 – R5 000.
Confirm the UV rating and warranty paperwork before you pay.

What to send with your request

Frequently asked questions

How much does borehole tank installation cost?

Fitting a 5 000L tank runs about R4 100 – R7 500, plus the tank. A 5 000L poly tank starts from ±R7 900.

How long does a poly borehole tank last?

Quality UV-stabilised tanks often carry a 10-year warranty. Many last 15 to 20 years when well positioned.

Do I need approval to install a tank on my borehole?

Boreholes using over 10 000 litres a day need national registration. Ask your municipality's building control about plumbing and stand approval.

Is a raised stand better than a ground tank with a pump?

A stand gives gravity pressure, but 3 m steel stands start near R13 440. A booster system for a ground tank costs about R5 000 – R15 000.

What tank size suits my household?

A home of four uses roughly 600 – 800 litres a day. A 5 000L tank gives about a week of reserve.
