WA Business Tips: Reduce Water Consumption Costs with Rainwater Tanks
“A penny saved is a penny earned”—the same principle is true for businesses. If you think about it, reducing your daily utility expenses can be just as good as increasing your revenue. One area where you can gain significant savings from is water use. For small-scale hospitality businesses in Perth such as hotels, restaurants, bars, and resorts, rainwater harvesting is a practical and eco-friendly way to protect one’s income stream from rising water costs.
You can notice a difference in your bottom line the moment you install rainwater tanks and connect them to your plumbing system for non-drinking purposes such as flushing the toilet, washing cars, watering gardens, and supplying sporting grounds, as well as for cleaning pavements. Here are some tips to get you started:
1. Measure your roof’s rainfall catchment capacity. This is essential in determining monthly capture potential for rainwater tanks. By tuning in to your local weather station or enquiring with the WA Bureau of Meteorology website, you can determine the monthly rainfall averages in your area. From there, measure your collection surface area (roof, gutters, etc.) in sq. metres then calculate your monthly capture potential using this formula:
Monthly capture potential (kl) = [collection surface area sq. m. x average monthly rainfall mm] / 1000
You can then call upon a local manufacturer like Rainfill Tanks and Curved Roofing Supplies for an installation estimate and expert advice.
2. Explore your options. There are different types of tanks available in Perth, but nothing beats corrugated iron water tanks in terms of availability, price, longevity, and aesthetic value. As for shape, you can choose between round and slimline water tanks. Although round water tanks provide extra storage for businesses with ample area, slimline water tanks are more suitable for properties with space limitations. At any rate, you can install multiple tanks to maximise catchment. An expert can advise you regarding what system and arrangement could be more space- and cost-efficient.
3. Connect tanks to plumbing. After understanding local regulations and installing the rainwater tank onsite, it is now time to find a professional to deal with the plumbing. Don’t just choose any plumber, though; find one who is fully licensed, especially if a Compliance Certificate has to be issued for the job. For better results, choose a plumber who has worked with rainwater tanks in the past.
Owning a rainwater tank not only helps reduce water consumption but is also a socially and environmentally responsible practice that can add aid your business reputation.
