Live indoor-versus-outdoor board, so a WaterSense toilet never pretends to fix a thirsty lawn.
Educational indoor-versus-outdoor sketch. Not a utility bill, leak audit, or drinking hydration guide.

01
Household water advice often collapses into one number: gallons per day, or “we installed low-flow heads.” That single total hides two clocks. Indoor use. Showers, toilets, faucets, laundry, dishwasher. Is fixture rating times habit minutes and loads. Outdoor use. Yard irrigation. is a schedule and a landscape, not a showerhead sticker.
This page’s framing is Indoor vs outdoor. Efficient fixtures can look like a win while a thirsty lawn still dominates weekly gallons. The twin board separates those clocks so priority is visible before you buy another aerator.
That is a different job from daily water intake (desk vs sweat for drinking/hydration) and from home energy (Bill vs footprint for electricity and fuels). Here we stay on municipal household water. Indoor end-uses versus outdoor irrigation. Not how much you should drink and not your kWh bill.
Decision framing: “Is my next gallon win indoors. Or is the yard already running the meter?”
02
The unique affordance is the twin weekly readout: indoor gallons versus outdoor gallons, with outdoor share of the total. Flip Suburban yard → Apartment with similar indoor habits. Indoor can look almost unchanged while outdoor collapses to zero. Indoor vs outdoor made visible, not a residual landfill twin and not a desk vs sweat hydration dial.
Per-person indoor daily and total daily sit under the board so you can compare habits without letting irrigation inflate “how much each person uses indoors.” Mixing those clocks is how a family with a green lawn gets told they shower too long when the sprinkler is the real story.
04
Showers, toilets, faucets, laundry, and dishwasher rails show share of indoor weekly gallons. Not of the outdoor-inclusive total. That keeps yard gallons from drowning fixture priorities when you are deciding between a shorter shower and a high-efficiency washer.
Flow rates (gpm / gpf) and minutes interact. A 2.5 gpm head for 14 minutes is a different indoor story from 1.8 gpm for 6 minutes. Same “shower” category, different habit × fixture product. The rails make which indoor end-use leads before you look at the yard.
05
Each indoor end-use is a weekly gallon estimate from household size, frequency, and flow or gallons-per-cycle. Outdoor is a direct weekly irrigation input. Totals and shares follow from those sums.
Factors are educational averages (typical WaterSense-era flows and load sizes). Your fixtures, leaks, guests, and controllers will differ. This is a planning sketch, not a billed meter read.

After Indoor vs outdoor, hand off for drinking hydration, home energy Bill vs footprint, waste Divert vs reduce, or whole-lifestyle inventory.
07
Scenario A. Apartment. Yard irrigation at 0. Yard-zero narrative; indoor rails and per-person indoor daily own the conversation. Indoor vs outdoor still matters as a check: you are not “missing” outdoor . It is simply absent.
Switch Apartment → Suburban yard without touching indoor inputs. Watch outdoor share and the twin board. Same showers, different meter story.
Scenario B. Suburban yard. Outdoor-led when irrigation is large. Fixture upgrades indoors still help the indoor clock; they may barely move total weekly gallons until the schedule or landscape changes.
Scenario C. Long showers. Indoor habit spike with modest yard. Indoor-led or balanced narrative: minutes × gpm on the shower rail leads indoors. Habit literacy before blaming the lawn.
Scenario D. Efficient + thirsty lawn. Low indoor flows and short showers, high irrigation. Outdoor-led chip: WaterSense indoors does not cancel flood irrigation outdoors. Celebrate each clock; pick the larger lever first.

Stop here for household municipal water literacy across indoor and outdoor clocks. Hand off for drinking hydration, home energy, waste hierarchy, or lifestyle inventory.

Indoor use (showers, toilets, faucets, laundry, dishwasher) is one clock. Outdoor irrigation is another. Efficient fixtures can look like a win while a thirsty lawn still dominates weekly gallons. Indoor vs outdoor.
Daily water intake owns desk vs sweat for drinking/hydration. This page owns household municipal water across indoor end-uses and outdoor irrigation. Not how much you should drink.
Home energy owns Bill vs footprint for electricity and fuels. Here the twin clocks are indoor gallons versus outdoor gallons. Same house, different meter story.
US gallons. Convert with a conversion tool if you work in liters. Factors are educational averages. Your fixtures and irrigation controllers will differ.
When outdoor irrigation is a large share of weekly gallons, indoor fixture upgrades move the total less than landscape or schedule changes. The twin board makes that priority visible.
No. It is a planning sketch from habits and flow rates. Bills include leaks, guests, pools, and rate tiers this panel does not model.
Each rail shows that end-use’s share of indoor weekly gallons. So you can see whether showers or toilets lead indoors before you look at the yard.
