Perth lives with water scarcity the way other cities live with traffic, permanently and mostly without thinking about it. Our rainfall has declined over decades, our supply leans heavily on desalination and groundwater, and every household drop genuinely counts. The encouraging part is that meaningful savings rarely require sacrifice, most water waste is habit and hardware rather than lifestyle, and fixing it usually saves money twice, on the water bill and on the hot water energy that rides along with it. Here are the eight changes we recommend, ordered by how much they matter.
One, hunt down the leaks
Before changing a single habit, stop the water you are losing for nothing. A running toilet, a dripping tap or a weeping retic fitting wastes more than most habit changes save, silently and around the clock. Read your water meter with everything off, wait an hour, and read it again. Movement means a leak, and the food dye test in the toilet cistern, a few drops, wait twenty minutes, look for colour in the bowl, finds the most common offender in minutes. Fixing leaks is the least glamorous and most effective item on this list, which is why it is first.
Two, shorten the shower, or at least upgrade the head
Showers are the biggest indoor water user in most homes, and the maths is simply minutes multiplied by flow rate. Trimming a couple of minutes helps, but if the habit will not budge, change the hardware instead. A modern efficient shower head cuts the flow substantially while maintaining genuinely good pressure, and because most shower water is heated, the saving lands on your energy bill as well. A four minute timer in the bathroom is the cheapest water saving device ever invented.
Three, fix the toilet situation
If your home still runs a single flush cistern, it is using far more water per flush than a modern dual flush unit needs, and multiplied across a household’s daily use, the difference is substantial. Upgrading the cistern is a modest job with a permanent payoff. And whatever cistern you have, resist the old brick trick, which damages valve components as it crumbles. Modern mechanisms are already engineered to the minimum effective flush.
Four, run appliances full, and choose them well
Dishwashers and washing machines use roughly the same water whether half full or full, so the free saving is simply waiting for a full load. When replacement time comes, the water rating label pays attention dividends, because efficient machines save on every single cycle for a decade. A modern efficient dishwasher, run full, typically beats hand washing the same load comfortably, which is one of the rare water saving facts that makes life easier.
Five, stop running the tap as a habit
Teeth brushing, vegetable rinsing and hand washing dishes under a running tap all share the same fix, a plug or a pause. A basin of water for rinsing vegetables, a closed tap while brushing, a sink of wash water rather than a running stream, none of these cost comfort, they just retire a habit formed when nobody counted litres. A jug of drinking water in the fridge similarly ends the summer ritual of running the tap cold.
Six, water the garden like a Perth local
The garden is where Perth households win or lose the most water. Water early in the morning within your rostered days, deeply and less often to train roots downward, and check your reticulation regularly, because a cracked fitting or stuck solenoid can quietly outconsume the entire house. Mulch generously, group plants by thirst, and lean native where you can, a waterwise Perth garden in full flight is proof that saving water and having a beautiful garden are the same project.
Seven, catch the cold water you already paid for
The water that runs while you wait for hot to arrive is clean, metered and usually lost. A bucket in the shower and a jug at the kitchen sink capture it for pot plants, cleaning and the kettle. If the wait for hot water is genuinely long, that is worth mentioning to a plumber too, since long dead legs of pipework waste water and energy on every use and can often be improved.
Eight, know your numbers
What gets measured gets managed. Compare your usage against the typical Perth household on your bill, watch the trend across seasons, and treat any unexplained rise as a leak until proven otherwise. Households that glance at the meter monthly catch problems at the trickle stage, and the habit takes one minute. Water efficiency is mostly the sum of small boring victories, and the meter is the scoreboard. If your numbers say something is leaking, or your fixtures are due for the efficient upgrade, Drains Plus can find the leak, fit the hardware and leave your home measurably thriftier. That is good for your bill and genuinely good for Perth.
If you want to go beyond the eight, the frontier is reuse. Greywater diversion from the laundry to the garden, rainwater tanks plumbed to toilets or the washing machine, and hot water recirculation systems all take Perth homes from efficient to genuinely thrifty, and several attract rebates from time to time. They involve licensed plumbing work and are worth sizing honestly against your usage, but for larger households and keen gardeners the payback is real. Start with the free eight, measure the difference, and then decide whether the hardware step earns its place.
