Hidden costs in water feature projects
- !Electrical work — every water feature needs power. GFCI-protected outdoor circuit, installed by a licensed electrician. Budget $500–$2,500 depending on distance from switchboard.
- !Water supply — top-up for evaporation. An outdoor tap nearby is essential. Running a new water line adds $200–$800.
- !Site preparation — any slope requires levelling. Rocky soil requires manual excavation. Access limitations add labour costs.
- !Ongoing pump electricity — a typical water feature pump costs $150–$500/year in electricity running 24/7.
Best value for most Australian homeowners: a well-designed pondless waterfall in the $7,000–$15,000 range delivers maximum enjoyment per dollar spent — beautiful sound, no standing water risks, minimal maintenance, and professional installation that will last 15–20 years with basic pump servicing.
