Pool removal: filling in or digging out, done properly

The kids grew up, the pool costs $1,500 a year in chemicals and power, the fence needs recertifying again — and the backyard would be worth more as lawn. Pool removal is one of the fastest-growing demolition jobs in regional Victoria. Here's what it actually involves and costs.

The two methods

Partial removal (fill-in) — the budget option

The pool is drained (legally — see below), the shell's top metre or so is broken off, holes are punched through the floor for drainage, the broken material goes into the void, and the hole is filled and compacted with clean fill, topped with soil. Typical cost: $5,000–$15,000. The catch: the land is generally classed as non-buildable — you can lawn or garden it, but a future extension, garage or new dwelling can't sit on it without expensive engineering, and the pool's presence should be disclosed when you sell. Cheap now, restrictive later.

Full removal — the clean-slate option

The entire shell — concrete, fibreglass or vinyl liner and its base — is broken out and carted away, and the hole is backfilled with controlled, compacted fill. Typical cost: $7,000–$18,000+ for a standard backyard pool, at the top end for big concrete shells with tight access. The result: land that (with compaction documentation) is genuinely reusable, no disclosure asterisk, and the best outcome for resale value.

What moves the price

• Shell type: fibreglass shells cut and lift out relatively easily; sprayed-concrete pools are demolition proper — hammer, excavator, many truckloads.
• Access: the decisive factor in regional towns' older streets. A machine that can drive to the pool is one price; craning over the house or barrowing through a 900mm side gate is another. Difficult access can add 30–50%.
• Size and depth: more shell, more fill. Fill isn't free — a typical pool void swallows 50–100+ cubic metres.
• Water disposal: a pool can't just be pumped into the street or a neighbour's paddock. Chlorinated water is dechlorinated and discharged per the local water corporation's rules, salt pools with extra care; sewer discharge needs the water authority's tick.

Permits and paperwork

Pool removal is demolition of a structure: a building permit is required for removal works, councils have requirements around decommissioning, and here's the step people love: once the pool is gone and certified, you deregister it from the council's pool register — ending the ongoing barrier inspection and certification cycle (and its fees) forever. The safety barrier must remain compliant right up until the pool can no longer hold water; the sequence matters and we manage it.

Above-ground pools: the easy version

Above-ground pools are the simple end of the trade: drain legally, dismantle the shell (steel walls usually go for scrap), and deal with the base — typically $1,500–$5,000 all-in depending on size, decking and access. The main trap is the sand or paved base pad left behind, which needs spreading or removal, and any deck built around the pool, which is a small demolition of its own. Still a permit conversation, still a deregistration step — just a much smaller cheque.

A worked example: filling in a 1990s concrete pool

A typical regional job — 8×4m sprayed-concrete pool, decent side access for a small excavator: drain and dechlorinate per the water corporation's guidance $400; break down the top shell and punch drainage $2,800; import, place and compact ~60 cubic metres of clean fill $3,600; topsoil and rough landscaping $900; building permit and council decommissioning/deregistration steps $800 — about $8,500, three days on site. The same pool fully dug out and carted, with documented compaction: closer to $14,000. Both numbers move with access — the identical pool behind a unit with no side gate is a crane conversation.

What you get back

Beyond the backyard: no more chemical and pump running costs (commonly $1,000–$2,000/year), no more barrier compliance certificates, lower insurance, and — agents in our towns confirm it — a bigger buyer pool at sale time, since family buyers split on pools but nobody objects to lawn. Payback on a partial fill-in is often under five years of running costs alone.
