Permaculture "wastewater" systems

  1. 1. Permaculture“Wastewater” SystemsGreywater and Black waterLisa DePiano
  2. 2. What is Greywater Anyway?   Water from your sinks, showers and washing machines   It is NOT water from your toilets or anything that has come into contact with Feces (Black water)   50-80% of residential “wastewater” is greywater Art Ludwig, Creating and Oasis with Greywater
  3. 3. Why Use Greywater?  Reduce use of Freshwater  Less strain on septic systems or treatment plants  More effective purification  Feasibility for sites unsuitable for a septic tank  Reduced use of energy and chemicals  Recharge Groundwater   Plant Growth  Reclamation of Nutrients  Increased awareness of natural cycles  More FUN!
  4. 4. Greywater Potential   Top Loader Washer: 30-50 gallons per load   Front Loader Washer: 10-15 gallons per load   Shower: low flow shower head (2.5 gall/min) x 10 minutes= 25 gallons   Bathtub: 30-40 gallons per bath   Kitchen Sink: 50-15 gallons per person per day
  5. 5. Greywater Guidelines   Do not store for more than 24 hours   Minimize direct contact   Do not allow anything toxic to go into the system   Make sure all greywater goes into the ground   Install 3-way valve for easy switching between greywater and sewer
  6. 6. Soaps and Products   Avoid Salt and Boron   Products that are salt and Boron Free: Oasis, ECOS, Bio Pac Liquid Detergent   Dr. Bronners, Aubrey Organics, some Burts Bee’s   Mostshampoos and Conditioners contain reproductive toxins and carcinogens check out cosmeticdatabase.org
  7. 7. Code/Legal Issues   Arizona, New Mexico and Texas- Residential Systems (under 400 gal/day) fall under permit and are “legal”   Australia- greywater is mandated, rebates
  8. 8. Grey Water Plants   Plants that don’t like greywater: drought dependent (oak tree), acid loving (blueberry, ferns)   Best for fruit trees, bushes, large annuals or perennials   FoodCrops: Do not put greywater on edible portion, no roots, salad, good for berries and fruit
  9. 9. Greywater DesignProcess
  10. 10. Choosing a System•  There are many different systems that can be tailored to you or your clients design goals, site and budget. •  The following slide is a list of some of the different types of greywater systems.
  11. 11. Choosing a System   Landscape Direct   Washer: Laundry Drum   Washer: “drumless laundry”   Shower/Sink: Branched Drain   Shower/Sink: “drum with effluent pump”   Solar Greywater Greenhouse   Constructed Wetlands
  12. 12. Drill bits for drilling holes through drywall 3-way valveHere are some basic greywater tools
  13. 13. Installing 3-way valve towasher so you can switchbetween the system and sewer
  14. 14. Connected and mounted to wall
  15. 15. Hole is drilled through exteriorwall and vented. PVC pipe bringswater down slope to landscape
  16. 16. Greywater is applied to mulch ring in landscape
  17. 17. Brick is added for flow
  18. 18. We all can install- Work with complementary skill sets
  19. 19. Other Waste WaterTreatment FLOATING “TRASH ISLAND”CONSTRUCTED WETLAND USING WASTE MATERIALS
  20. 20. Constructed Wetland •  We mimic the way that a wetland cleans water. •  Water enters system through a washing machine and gravity fed into bathtubs filled with gravel and wetland plants. •  We create habitat for aerobic and anaerobic bacteria. They digest carbon, nitrogen and phosphorus which they use as nutrients. Rhizome Collective, Austin, TX
  21. 21. •  Mimics floating islands inStorm Water Runoff nature when lake bank breaks from the shore. •  Plant roots hold “island” together creating habitat for bacteria, zooplankton and other organisms which uptake excess nutrients and break down toxins •  This is used in a storm water run off pond in Floating Island, Austin, TX Texas. Made from “trash” on site.
  22. 22. Black Water•  Water containing fecal matter•  Different contamination level and process•  Best solution is source separation of fecal matter from clean drinking water•  “Less than 2/10ths of 1 % of the planets water is drinkable, and 90 % goes to buildings, including flushing toilets.” –national resources defense council
  23. 23. Black Water Treatment"Black waterBucket system Composting toilet Methane digester Living MachinePros, inexpensive, Onsite, low energy, Can be used to Uses biologicalSimple, direct Can be used as provide gas or resources,contact- visible fertilizer, energy, delt with BeautifulLow energy Decentralized onsite Large ScaleCons- direct Cultural View, Cost Energy intensive,contact, visible improper Cost,Cultural Views management Centralized The above is a chart of black water treatment options with pros and cons
  24. 24. Dockside Green, CN•  Permaculture Design for community scale.•  Located on a 15 acre Brownfield on Victorias waterfront. It’s a mix business and residential development containing 26 buildings totaling 1.3 million square feet.•  Treating 702,240 gallons of wastewater per week. Water used to flush toilets and irrigate landscaping. Extra water will go to canal treated with plants.•  Water feature increases real estate sales•  www.docksidegreen.com
