As a resident of Gilbert, you’re no stranger to the challenges of maintaining a beautiful landscape in the dry, arid climate of the Southeast Valley. Conserving water while keeping your yard lush and vibrant can seem like an uphill battle. But what if I told you there’s a resource you’re probably overlooking? That resource is greywater.
What is Greywater?
Greywater refers to the gently used water from your bathroom sinks, showers, tubs, and washing machines. It does not include water that has come into contact with feces, such as may be present in water from toilets or from washing diapers. Because greywater is relatively clean, it’s a safe and eco-friendly option for watering your garden or lawn.
However, there are certain guidelines you must follow when using greywater in your landscaping to prevent health risks and damage to your plants. Below, I’ll provide some advice on how to use greywater safely and efficiently in your Gilbert yard.
Understanding Greywater Regulations in Gilbert
Before you start rerouting your home’s plumbing, it’s important to understand the regulations surrounding greywater use in Gilbert. The Arizona Department of Environmental Quality (ADEQ) has established certain rules for greywater use to protect public health and the environment. For instance, greywater must be used on the property where it’s generated and cannot run off to neighboring properties or public areas.
It’s also crucial that greywater is used within 24 hours of generation, as it can develop a foul odor and harmful bacteria if stored. Make sure you familiarize yourself with these and other regulations to avoid any legal issues and ensure the safe use of greywater in your landscaping.
Choosing the Right Plants for Greywater
Not all plants are suitable for greywater irrigation. It’s best to use greywater for ornamental plants and trees rather than vegetables or fruits that come into direct contact with greywater. This is because greywater can contain bacteria and chemicals from soaps and detergents.
When choosing plants for your greywater system, consider species that are tolerant of alkaline soil, as greywater can raise your soil’s pH. Native plants are a great choice, as they’re well-adapted to the local climate and soil conditions of Gilbert. Some good options might include Desert Marigold, Brittlebush, or Blue Palo Verde.
Setting Up a Greywater System
Setting up a greywater system may seem complex, but with some planning and effort, it’s a manageable DIY project. Start by identifying the sources of greywater in your home. The easiest and most common source to access is the washing machine, as it produces a large volume of greywater and doesn’t require major plumbing alterations.
There are different types of greywater systems, but a simple one involves running a hose from your washing machine out to your garden. Remember to use the greywater within 24 hours and only on established plants, as greywater can be too strong for seedlings or young plants.
Maintaining Your Greywater System
Maintenance is key in ensuring your greywater system operates efficiently and safely. Regularly check your system for leaks or blockages and clean it as needed. Remember to prune your plants regularly and monitor their health. If you notice any signs of stress or disease, reassess your greywater use.
It’s also important to use greywater-friendly products in your home. These are products that are low in salts and free of boron, a common ingredient in detergents that can be toxic to plants. By choosing greywater-compatible products, you’ll protect your plants and the environment.
With careful planning and maintenance, greywater can be a valuable resource for your Gilbert landscaping. It not only helps you conserve water but also saves you money on your water bill. So why not give it a try?
