return to Measurement Pages

Our goal with water usage was to use water at a fraction of a level of a traditional commercial office building. We did this in a variety of ways, from selection of efficient plumbing fixtures to reduction of use of city water through the use of cisterns. Our data is below.

Our 2 cisterns, prior to placement. The larger cistern, 1,400 gallons, is under our parking lot, and the smaller, 500 gallons, is on top of our 3-season room. Both are fed with water coming from our roof.

Measurement Decisions

  • The statistics come from our monthly City of Detroit water bills.
  • Unit of measure = gallons (water dept measures in cu, where 1cu = 100 cubic feet = 728 gallons)
  • 'Usage Per Person' is calculated based on the number of people that are in Businesses-in-Residence at the beginning of each month, plus the number of volunteers and paid contractors that work more than 2 days a week.

Sources of Water

  • Our water comes from the City of Detroit Water and Sewerage Department, which gets its water from the Detroit River and Lake Huron.
  • Water for outside use comes from 2 cisterns, one on top of our roof, and one under our parking lot. Together, they collect about 2,000 gallons of water.

Uses of Water

  • 4 Toilets (@ 1.28 gal/flush)
  • 5 Sinks
    • 3 Bathroom (0.5 gal/min + automated)
    • 1 Kitchen
    • 1 Mop-basin
  • 2 Dishwasher (4 gal / load)
  • 1 Shower (2.5 gal/min shower head)
  • Coffee / Drinking
  • Outdoor watering. We harvest the water that we use for outdoor watering in 2 cisterns (1,700 gallons total) and only use city water when the other water is exhausted. Our goal is to use no city water for outdoor use.
