Water Features near you

Victoria's Better Health Channel states that a toddler or child can drown in five centimetres of water, and lists ponds among the water sources to cover with mesh, alongside bird baths and similar sources. It also makes the wider point that every exposed water source, however shallow, is a significant danger, and mentions the ones people forget entirely, such as septic pits and pet water bowls.

The design answers are ordinary and effective. A pondless reservoir feature removes the hazard rather than managing it. A rigid mesh or grate set just under the water surface makes a pond look like a pond and behave like a solid surface. Restricting access to the part of the garden that holds the feature works if the restriction is real rather than notional.

Note that pool and spa barrier law is a separate matter with its own depth test and its own state registers, and it is covered in the pools and fencing guides rather than here. Do not assume a water feature is exempt because it is decorative; check the definition that applies in your state before you dig.

NSW Health's guidance on reducing mosquitoes around the home tells householders to empty and wipe out bird baths, pet water bowls and water features, and to fill pot plant bases with sand to avoid standing water. Its reason for caring is mosquito-borne disease, and it names Japanese encephalitis as a specific risk when mosquito populations rise after flooding. For rural dams and ground pools it suggests keeping them free of vegetation and introducing a local species of fish or using mosquito control agents.

The practical rule that follows is that a feature is safe while the pump is running and becomes habitat when it stops. Mosquito larvae need still water; a surface that is genuinely disturbed does not support them. That makes pump reliability a health question rather than a convenience one, and it makes a feature that runs on a timer for two hours a day a worse idea than it sounds.

If you leave the house for a few weeks in summer, the correct action is to empty a small feature rather than to leave it running unattended. A pump that fails on day three of a holiday leaves you a breeding site for a month.

The pump, the lighting and any filtration are electrical work, and electrical wiring work is licensed in every Australian state and territory regardless of size. The NSW Government's home electrical safety advice puts the principle plainly — do not mix electricity and water — and describes safety switches as devices that cut the electricity supply to protect you from serious electric shock, injury or death and help prevent electrical fires.

In New South Wales the electrician must give Building Commission NSW a Certificate of Compliance for Electrical Work showing the work has been tested and complies with the Gas and Electricity (Consumer Safety) Regulation 2018, and the certificate has to be submitted as soon as practical and no later than seven days after the electrical test. Ask for a copy. An outdoor circuit installed by a landscaper without an electrician is the single most common corner cut on this kind of job.

Most problems with a small feature are mechanical. The pump intake blocks with leaf litter, the flow drops, the surface stills, and algae takes over within days. A weekly clear of the intake screen in the warm months prevents nearly all of it. A feature with fish and plants is a different system: it wants stable water, shade over part of the surface, and restraint with anything you add to it.

Resist the urge to dose a small ornamental feature with chemicals. Anything strong enough to kill algae in a bowl will kill whatever else is living in it, and it ends up in the garden bed when you drain the feature. Shade, movement and regular emptying do more, and they are what the public health advice asks for anyway.
