Unlock Endless Water Supply with Grey Water Secrets
Have you ever paused to consider the fate of the water that flows down your home’s drains? From waiting for the shower to reach the perfect temperature to straining pasta or leaving half-empty water bottles, we often let valuable water slip away without a second thought. This isn’t an uncommon oversight, as our plumbing systems are designed to whisk away excess water, leading us to believe it’s no longer useful.
However, in areas facing droughts or for those keen on reducing water bills and conserving resources, reusing this water, known as grey water, presents a viable solution. Understanding the different types of water—white, grey, and black—is crucial in this endeavor. White water is clean, entering our homes from taps, while black water, like toilet water, is heavily contaminated. Grey water, which is not entirely clean but not toxic, can be repurposed for various non-consumptive uses.
Grey water is typically sourced from showers, sinks, and washing machines. Although it contains residues from washing, bathing, and cooking, it remains unusable for drinking but can be a boon for other applications. For instance, while it’s unsuitable for vegetable gardens due to contamination risks, it can nourish fruit and nut trees, as they are less likely to come into direct contact with the contaminated water.
“Take care to prevent grey water from coming into contact with any fruits and vegetables due to the contamination risk (especially if the produce may be consumed raw),” advises How Stuff Works. Additionally, it’s crucial to avoid storing grey water for more than 24 hours, as it will start to degrade and produce unpleasant odors.
The Water Wise Group warns, “Ensure that greywater soaks into the ground. Try not to allow it to pool up or run off. […] Stagnant greywater can create mosquito breeding grounds, as well as an area for potential human contact with greywater.” Therefore, proper management and application are key to effective grey water reuse.
Before embarking on a grey water collection journey, it’s important to be aware of local regulations. The EPA notes, “EPA does not require or restrict any type of reuse. Generally, states maintain primary regulatory authority (i.e., primacy) in allocating and developing water resources.” This means regulations can vary widely, so checking with local authorities is a prudent first step.
Collecting grey water can be as straightforward or complex as desired. Simple methods include placing a bucket in the shower to catch unused water or collecting ice cubes to water plants. Cooking water, such as that from rinsing vegetables or pasta, can also be saved and reused.
Aquarium water, rich in nutrients like nitrogen and phosphorous, can be repurposed for landscaping, though it’s important to avoid using saltwater aquarium water due to its high salt content. “Aquarium water is very good for plants because it contains materials such as nitrogen, phosphorous, potassium and ammonium and other microorganisms found in soil sediments, which can act as a natural fertilizer,” explains Conserve Energy Future.
For those interested in more structured systems, rain barrels can collect roof runoff, and grey water collection systems can be installed to divert water from showers and washing machines for irrigation. If you’re considering an indoor system, consulting a plumber is advisable, while outdoor systems might benefit from a landscaper’s expertise.
With a water filtering system, grey water can be further utilized, even for activities like laundry. DIY enthusiasts can find numerous instructional videos online to guide the construction of a grey water collection system. The Tiny Life provides a basic outline: identify drain points, plan drainage routes, ensure proper elevation, and install valves and pipes accordingly.
Whether opting for a simple bucket or a comprehensive system, reusing grey water offers an effective way to conserve water and contribute to environmental sustainability.
