Planning Your Tiny Home Greywater System

Designing an effective greywater system requires careful planning to maximize efficiency in your limited tiny home space.

Assessing Water Usage Patterns

Start by tracking your daily water consumption from each source. Monitor how many gallons flow from your shower (15-25 gallons/day), bathroom sink (3-5 gallons/day) and washing machine (15-30 gallons/load). Create a water diary for two weeks to identify peak usage times and potential collection points. Understanding your usage patterns helps determine the right system size and storage capacity for your needs.

Choosing the Right Collection Methods

Select collection methods based on your tiny home’s layout and available space. Install a branched drain system for shower and sink water that uses gravity flow to reduce complexity. Consider a drum system with removable filters for laundry water collection. For limited spaces choose compact surge tanks (30-50 gallons) that can fit under raised floors or in exterior compartments. Ensure all collection points have easy maintenance access.

Understanding Local Regulations

Research your area’s specific greywater codes before installation. Many jurisdictions require permits for systems processing over 250 gallons per day. Check setback requirements from property lines (typically 5-10 feet) and depth regulations for subsurface irrigation. Contact your local health department for approved greywater-safe soaps and detergents. Some areas restrict kitchen sink water recycling due to high organic content.

Installing Basic Greywater Collection Systems

Sink and Shower Water Diversion

Install a three-way diverter valve under your sink or shower drain to redirect greywater efficiently. The diverter connects to a 1.5-inch PVC pipe that slopes downward at a minimum grade of 2% to ensure proper flow. Use flexible corrugated pipes for shower connections to accommodate tight spaces while straight PVC works best for under-sink installations. Add a mesh strainer at collection points to catch hair debris particles.

Filtration Methods for Safe Outdoor Use

Create a compact filtration system using a series of graduated filters starting with a 100-micron screen. Install a mulch basin filled with wood chips wood shavings or bark to naturally filter particles while providing beneficial nutrients. Connect a small activated carbon filter before the storage tank to remove soap residues chemicals. Use biosponge filters in vertical arrangements to maximize space efficiency while ensuring water quality.

Storage Solutions for Small Spaces

Utilize slim-profile water tanks that fit against exterior walls or under deck spaces. Install 30-50 gallon surge tanks vertically to minimize footprint while maintaining adequate storage capacity. Consider collapsible water bladders that can be stored flat when not in use or underground cisterns if space permits. Add floating sensors to monitor water levels automatically triggering overflow prevention systems when tanks reach capacity.

Creating an Outdoor Living Oasis With Recycled Water

Transform your tiny home’s outdoor space into a sustainable paradise using your greywater recycling system as the foundation for a vibrant ecosystem.

Designing Water-Efficient Garden Spaces

Create zones based on water needs by grouping plants with similar requirements together. Install permeable pathways using gravel or stepping stones to maximize water absorption. Position water-loving plants like ferns and hostas near greywater output points while drought-resistant herbs and natives can thrive in outer areas. Use vertical gardening techniques with wall-mounted planters to save ground space while incorporating efficient watering channels.

Installing Drip Irrigation Systems

Set up a gravity-fed drip system using 1/2-inch mainline tubing connected to your greywater output. Install pressure-compensating emitters at 12-inch intervals to deliver water directly to plant roots. Use 1/4-inch micro-tubing to reach container plants and vertical gardens. Add a basic filter at the system’s start point to prevent debris buildup and incorporate adjustable flow controls to manage water distribution effectively.

Building Natural Filtration Zones

Construct a three-tier filtration system using repurposed containers filled with gravel sand and activated charcoal. Plant water-purifying species like cattails and rushes in the first zone to filter larger particles. Create a rock garden in the second zone using various-sized stones for additional filtration. Add a final reed bed section with wetland plants to polish water before it reaches garden areas.

Maintaining Your Greywater System Year-Round

Proper maintenance ensures your greywater system operates efficiently while maximizing its benefits for your outdoor living space.
