When one homesteader with a creek, a well, and rainwater catchment asked how much water a household really needs, one answer stood out for how modest it was.
Here's what to know
In an r/homestead thread, a Reddit user said they were "trying to figure out how much [water] I need to plan to use." They estimated they used about 15 gallons per load of laundry, 1.5 to 3 gallons per minute in showers, 1 gallon per minute at sinks, and 1.4 gallons per flush.
"Is that right?" they wondered. A household of four with a dog, a cat, and around 20 chickens replied that it uses roughly 700 gallons a week in the spring.
That total rises to roughly 1,000 gallons in summer, when gardening adds about 300 more gallons, but the discussion showed that self-managed households can use less water than people expect when they actively track it.
"Way lower than I would've guessed," one person remarked.
Another commenter said their two-person household used about 80 gallons a day. When a third person joined them, that total rose to roughly 116 gallons daily, or around 3,500 gallons a month, with their garden sustained by rain or rain catchment "90% of the time."

"We spent 7 years living off grid in an RV so we're really good at conserving water," they shared.
More background
The thread also showed how water demand can vary significantly depending on household habits, from longer showers to landscaping. One person said, "When I lived in the suburbs it was not uncommon to use 20-30k gallons a month for household and lawn/garden watering."
Beyond capturing water with rain barrels, many residents are transitioning to natural lawns or rewilding their yards to lower water bills and lawn maintenance, and to support local wildlife.
What can be done?
Planning a well, storage tank, or backup water setup depends on measuring actual use whenever possible instead of relying only on fixture estimates.
In the thread, people used hauled-water totals, utility meter histories, and even water-softener cycling to estimate demand.
Another data point came from the commenter who said they had spent seven years living off-grid in an RV. They said their water softener cycles every 700 gallons and now runs every six days with three people, versus every nine days when there were two.
Laundry also came up as an easy category to underestimate. As one commenter put it, "Washing clothes is the thing that uses probably over half of our water usage." While gardening can also require a lot of water, it can lower grocery bills, providing a significant return.
