Understanding Water Consumption
Water is a precious resource, especially in Australia. Understanding how much water your household uses is the first step towards sustainable water management. The average Australian uses around 200 litres of water per day, but this can vary significantly depending on lifestyle, garden size, and water-using appliances.
Tracking Your Usage
Monitor your water bill: Your water bill provides a detailed breakdown of your water consumption over a specific period. Compare bills from different months to identify trends and potential areas for improvement.
Read your water meter: Learn how to read your water meter. Taking regular readings (e.g., weekly) allows you to track your usage more closely and identify leaks early on. Contact your local water authority for instructions on how to read your meter.
Use a water audit tool: Many water utilities offer online water audit tools that help you estimate your water usage based on your household size, appliances, and habits. These tools can provide valuable insights into where you can save water.
Identifying Water-Intensive Activities
Certain activities consume significantly more water than others. Common culprits include:
Showering and bathing: Long showers and frequent baths can use a substantial amount of water. Consider shorter showers and using a water-efficient showerhead.
Toilet flushing: Older toilets can use up to 12 litres per flush. Upgrading to a dual-flush or low-flow toilet can save a significant amount of water.
Laundry: Washing machines can use a lot of water, especially older models. Always wash full loads and consider a water-efficient washing machine.
Dishwashing: Dishwashers use less water than handwashing, but only when run with a full load. Scrape food off plates before loading and avoid pre-rinsing.
Garden watering: Watering lawns and gardens can be a major water consumer, especially during dry periods. Implement water-wise gardening practices to reduce your water needs.
Water-Saving Fixtures and Appliances
Investing in water-saving fixtures and appliances is a highly effective way to reduce your water consumption and save money on your water bill. These fixtures are designed to use less water without compromising performance.
Toilets
Dual-flush toilets are a popular choice, allowing you to use less water for liquid waste. Look for Water Efficiency Labelling and Standards (WELS) rated toilets. A 4-star or higher rating indicates excellent water efficiency.
Showerheads
Water-efficient showerheads restrict water flow without sacrificing water pressure. Choose a showerhead with a WELS rating of 3 stars or higher. Aerating showerheads mix air with water, providing a satisfying shower experience while using less water.
Taps
Install aerators on your taps to reduce water flow without affecting water pressure. Aerators are inexpensive and easy to install. Look for taps with a WELS rating of 4 stars or higher.
Washing Machines
Front-loading washing machines are generally more water-efficient than top-loading machines. Look for a washing machine with a high WELS rating (4 stars or higher). Consider features like load sensing, which adjusts the water level based on the size of the load.
Dishwashers
Choose a dishwasher with a high WELS rating (4 stars or higher). Look for features like soil sensors, which adjust the water usage based on the cleanliness of the dishes. Always run the dishwasher with a full load.
Rainwater Harvesting Systems
Rainwater harvesting involves collecting rainwater from your roof and storing it for later use. This is a great way to supplement your water supply and reduce your reliance on mains water. Rainwater can be used for various purposes, including garden watering, toilet flushing, and laundry.
Types of Rainwater Tanks
Poly tanks: Polyethylene (poly) tanks are lightweight, durable, and relatively inexpensive. They are available in various sizes and shapes.
Concrete tanks: Concrete tanks are strong and long-lasting. They provide excellent water quality due to their alkaline properties, which help neutralise acidic rainwater.
Steel tanks: Steel tanks are durable and aesthetically pleasing. They are available in a range of colours and finishes.
System Components
A rainwater harvesting system typically includes the following components:
Roof and gutters: The roof acts as the collection surface, and gutters channel the rainwater to the tank.
Leaf screens and gutter guards: These prevent leaves and debris from entering the tank.
First flush diverter: This diverts the first flush of rainwater, which may contain contaminants, away from the tank.
Tank: The tank stores the collected rainwater.
Pump: A pump is needed to deliver the rainwater to its intended use.
Filtration system: A filtration system removes any remaining sediment or contaminants from the rainwater.
Installation and Maintenance
Installing a rainwater harvesting system may require professional assistance. Ensure that the system is installed according to local regulations and building codes. Regular maintenance is essential to keep the system functioning properly. Clean the leaf screens and gutter guards regularly, and inspect the tank for any signs of damage.
Greywater Recycling
Greywater is wastewater from showers, baths, sinks, and washing machines. It does not include wastewater from toilets or kitchen sinks. Greywater can be recycled for non-potable uses, such as garden watering and toilet flushing.
Types of Greywater Systems
Diversion devices: These simple systems divert greywater directly to the garden. They are suitable for small-scale applications.
Treatment systems: These systems treat greywater to remove contaminants before it is reused. They are more complex and require regular maintenance.
Benefits of Greywater Recycling
Reduces water consumption: Greywater recycling can significantly reduce your reliance on mains water.
Saves money: Lower water bills.
Reduces environmental impact: Conserves water resources and reduces the demand on water treatment plants.
Regulations and Considerations
Greywater recycling is subject to regulations and guidelines. Check with your local council to determine the requirements in your area. It is important to use greywater safely and responsibly to avoid health risks. Use biodegradable soaps and detergents, and avoid using greywater on edible plants.
Water-Wise Gardening Practices
Gardening can be a water-intensive activity, but there are many ways to reduce your water consumption while still maintaining a beautiful and healthy garden.
Plant Selection
Choose native and drought-tolerant plants that are well-suited to your local climate. These plants require less water and are more resistant to pests and diseases.
Mulching
Apply a layer of mulch around your plants to help retain moisture in the soil and suppress weeds. Organic mulches, such as wood chips and straw, also improve soil health.
Efficient Irrigation
Water deeply and less frequently: This encourages deep root growth, making plants more drought-tolerant.
Water in the early morning or late evening: This reduces water loss due to evaporation.
Use a watering can or hose with a trigger nozzle: This allows you to target water directly to the roots of plants.
Install a drip irrigation system: Drip irrigation delivers water slowly and directly to the roots of plants, minimising water waste.
Soil Improvement
Improve your soil's water-holding capacity by adding organic matter, such as compost and manure. Healthy soil retains moisture better and reduces the need for frequent watering.
Group Plants with Similar Water Needs
Group plants with similar water requirements together to make watering more efficient. This allows you to water each area of your garden according to its specific needs.
Detecting and Fixing Leaks
Even small leaks can waste a significant amount of water over time. Regularly check your taps, toilets, and pipes for leaks. A dripping tap can waste litres of water per day, and a running toilet can waste even more.
Checking for Leaks
Read your water meter: Turn off all taps and water-using appliances, and then read your water meter. Wait for 30 minutes, and then read the meter again. If the reading has changed, you likely have a leak.
Check your toilets: Add a few drops of food colouring to the toilet tank. If the colour appears in the bowl within 30 minutes, you have a leak.
Inspect your taps and pipes: Look for drips, puddles, or signs of water damage around your taps and pipes.
Fixing Leaks
Tighten loose connections: Many leaks can be fixed by simply tightening loose connections on taps and pipes.
Replace worn washers: Worn washers are a common cause of dripping taps. Replacing the washer is a simple and inexpensive repair.
Repair or replace damaged pipes: If you have a leaking pipe, it may need to be repaired or replaced. If you are not comfortable doing this yourself, hire a plumber.
