RV Grey Water Recycling: The Ultimate Guide
Understand Greywater and Its Importance
Greywater, also spelled gray water, is wastewater from showers, bathroom sinks, and washing machines. It differs from black water, or "poop water," which comes from toilets and contains harmful pathogens. Greywater recycling systems are crucial for RV owners aiming to maximize water conservation efforts, significantly reducing overall water usage. With proper treatment, greywater becomes a valuable resource for non-potable uses like irrigating flower beds and gardens, especially beneficial when traveling off-grid or in remote areas with limited access to clean water.
Benefits of Greywater Recycling in RV Life
Utilizing a grey water recycling system in your RV supports extensive water conservation efforts. Recycling greywater can save hundreds of gallons of water each month, significantly reducing freshwater tank refills and extending boondocking capabilities. Additionally, grey water recycling reduces strain on waste tanks and conserves potable drinking water for essential tasks, preserving clean water for human consumption and cooking. Environmentally, using recycled greywater for watering flower beds and non-edible plants helps sustain ecosystems and reduces the glut of water dumped at dump stations or RV parks.
Types of Greywater Recycling Systems for RVs
Several types of greywater recycling equipment exist, including:
-
Simple Filtration Systems: Basic water filters connected to collection pipes and flow pipes, suitable for watering flower beds.
-
Advanced Grey Water Recycling Kits: Include storage tanks ranging from 80-100 gallons, additional pumps, and internal plumbing to ensure consistent water flow.
-
Water Recycling Showers: Specialized showers that recycle shower water by cleaning and reusing it, substantially lowering hot water and cold water consumption by up to 70%.
Key Components of a DIY Greywater Recycling System
A DIY greywater recycling system typically involves:
-
Collection Pipes: Drain water from bathroom sinks, showers, and plug holes.
-
Grey Water Tank: Storage tank positioned in storage bays to hold untreated water.
-
Water Filter: Ensures water is safe for use on flower beds by removing skin, food particles, soap residue, and food chunks.
-
Additional Pumps: Including volt pumps or additional pumps to manage water flow effectively.
-
Internal Plumbing and Additional Plumbing Modifications: Customized internal plumbing setups to manage the movement of recycled grey water efficiently.
-
Overflow Pipes: Safety measure to prevent overflow and manage excess water flow.
Step-by-Step Guide to DIY Greywater Recycling System
Creating your DIY grey water recycling system involves these steps:
-
Planning and Compliance: Research grey water laws to comply with local regulations.
-
Installing Plumbing: Set up internal plumbing, collection pipes, overflow pipes, and flow pipes.
-
Tank Placement: Place the grey water tank securely within storage bays.
-
Installing Additional Pumps: A volt pump or additional pumps ensure consistent water flow.
-
Adding Filters: Use antibacterial or enviro'friendly soaps to minimize contaminants, install water filters such as carbon-based filtration.
-
System Integration: Connect internal plumbing and waste pipes securely.
-
Safety Installation: Set up overflow pipes and reed switch mechanisms for automatic shut-off.
Importance of Filtration and Maintenance
Quality filtration, from basic water filters to advanced multi-stage filtration systems with water recycling equipment, ensures greywater is safe and odor-free. Carbon filters remove food debris, food particles, food chunks, and soaps. Advanced systems utilize additional pumps or volt pumps and sometimes water recycling showers that employ innovative recycling to minimize water heater usage. These showers recycle shower water by maintaining the water flow and temperature, reducing the use of potable water.
Safe and Effective Usage of Recycled Greywater
To safely use recycled greywater:
-
Avoid contact with greywater or using it as drinking water, as it's untreated and non-potable.
-
Use thefiltered water strictly for irrigation of non-edible plants and flower beds.
-
Periodically inspect your greywater recycling system to ensure the water flow remains unobstructed.
-
Dispose of excess grey water at designated dump stations or in properly dug 12-24 inch deep cat holes in remote areas where allowed.
Legal and Ethical Considerations
Always verify grey water recycling and disposal practices are legal at your location. While grey water recycling is encouraged for water conservation, many states have specific grey water laws governing the disposal and treatment of recycled water. Respecting these laws avoids penalties and protects local ecosystems.
Regular Maintenance and Troubleshooting
Proper maintenance involves:
-
Regular cleaning of the grey water tank and water filter every few months.
-
Checking water flow regularly for leaks in pipes, storage tanks, and pump systems.
-
Cleaning shower recycling systems to prevent clogs from food debris or skin products.
-
Regularly inspect and replace reed switch or switch mechanisms if necessary.
Practical Tips for Maximizing Water Recycling
-
Monitor water usage closely; aim for efficient consumption.
-
Install additional pumps or volt-operated pumps for improved water flow.
-
Prefer environmentally friendly, biodegradable soaps.
-
Insulate pipes and tanks to maintain hot water temperatures, reducing strain on the water heater.
-
Combine the use of hot water and cold water wisely to minimize energy consumption and maximize freshwater savings.
Conclusion
RV grey water recycling systems are vital for sustainable living on the road, particularly for boondockers. By effectively managing water from showers, bathroom sinks, and washing machines, you can extend freshwater supplies, lower environmental impact, and enhance your RV living experience. Implementing an efficient grey water recycling system, maintaining it regularly, and adhering to local regulations will optimize your water conservation efforts and contribute positively to sustainable RV travel.
