Example of Water Consumption Estimation

Let's calculate the approximate consumption for a household of 3 people, with the following estimated habits:

• Shower: 1 per person/day, 5 minutes duration (considering an efficient head of 10 Liters/minute).
• WC: 5 flushes per person/day (considering a modern 6 litre/flush tank).
• Washbasin: 3 minutes of use per person/day (tap open, approx. 6 Liters/minute).
• Washing machine: 4 loads per week for the entire home (considering 50 Liters/load).
• Dishwasher: 1 cycle per day for the entire home (considering 15 Liters/cycle).
• Kitchen/Other: (Let's assume about 10 L/person/day for drinking, cooking, minor cleaning).

Performing the Estimated Calculation (Daily):

1. Shower: 3 pers. * 1 shower/pers. * 5 min/shower * 10 L/min = 150 L
2. WC: 3 pers. * 5 discounts/pers. * 6 L/off = 90L
3. Washbasin: 3 pers. * 3 min/pers. * 6 L/min = 54 L
4. Washing machine (daily average): (4 loads/week / 7 days/week) * 50 L/load ≈ 28.6 L
5. Dishwasher: 1 cycle/day * 15 L/cycle = 15 L
6. Kitchen/Other: 3 pers. * 10 L/pers. = 30 L
7. Estimated Daily Total: 150 + 90 + 54 + 28.6 + 15 + 30 ≈ 367.6 Liters

Monthly Projection (approx. 30 days):

• Monthly Consumption (Liters) ≈367.6 L/day × 30 days ≈11,028 Liters
• Monthly Consumption (Cubic Meters) ≈11.028 L/1000 L/m3 ≈11.03 m3

📊 Estimated Result: This household would consume approximately 368 Liters per day, which is equivalent to about 11 cubic meters (m³) per month.

Note: This is an estimate based on averages. Actual consumption may vary. Use the calculator based on your own habits for a more personalized estimate.

How Does Our Water Consumption Calculator Work?

Estimating your home's water usage is easy by following these steps:

Step 1: Indicate the Number of People

👨‍👩‍👧‍👦 Indicate how many people normally live in your home.

Why is it important? Many uses (shower, toilet, sink) are per person, while others (washing machine, irrigation) are per household.

Step 2: Estimate Your Water Use by Category

💧 Review the different water usage categories listed (Shower, Toilet, Washing Machine, Kitchen, Irrigation, etc.).

💧 Enter the requested information for each one, which could be:

* Frequency: Times per day or week that you perform the activity (e.g. number of showers, number of washing machine loads).

* Duration/Quantity: Minutes that the activity lasts (e.g. shower) or number of times (e.g. toilet flushes).

💧 If you don't know your exact data, the calculator may offer average values as a reference (e.g., liters/minute of shower, liters/toilet flush). Be as realistic as possible!

Why is it important? The accuracy of your estimate depends directly on the quality of the data you enter about your habits.

Step 3: The Calculator Adds and Projects

The tool will calculate the estimated daily consumption for each category, considering whether it's per person or per household. It will then total all of these daily consumptions. Finally, it will project this daily total to monthly consumption (usually multiplying by 30 days):

Monthly Consumption≈(∑Daily Consumption by Category)×30

Why is it important? Automate the complex calculation of adding up all your usage and converting it to a monthly figure comparable to your water bill.

Step 4: Get your Estimated Total Consumption

📊 Done! The calculator will show you the total estimated water consumption for your home, usually in:

• Liters per day
• Liters per month
• Cubic meters (m³) per month (This is the unit that usually appears on the water bill in Chile).

Why is it important? It gives you a clear view of your total consumption and a basis for comparing it with averages or your bill.

Step 5: Identify Savings Opportunities

Review the results by category (if the calculator displays them) to see where the highest consumption is in your home. Is it the shower? The toilet? Irrigation? Focusing your savings efforts on the areas with the highest consumption will have the greatest impact.

What is the Domestic Water Consumption Calculator?

This calculator is an interactive tool designed to estimate the total amount of potable water used in a home over a given period, typically a month.

It works by asking the user for information about their consumption habits in different categories (shower, bath, cooking, laundry, watering, etc.) and the number of people in the household.

It uses this data, along with average consumption values by activity (liters per minute of shower, liters per toilet flush, etc.), to calculate an estimated total daily consumption, which it then projects to a monthly consumption.

Its main purpose is to generate awareness on personal and family water use, identify the activities that consume the most and provide a estimate that can be compared with the water bill or with consumption averages.

It's an educational and planning tool, not an accurate measure of actual consumption (that's what your home's water meter is for).

Avoid These Common Mistakes When Estimating Your Consumption

The calculator's accuracy depends on your data. Common estimating errors include:

• 🚫 Underestimating “Small” but Frequent Uses – Leaving the faucet running while brushing your teeth or washing dishes by hand can add up to many liters per month.
• 🚫 Forget Occasional or Seasonal Uses – Watering the garden in the summer, filling a small pool, or washing a car can significantly increase consumption.
• 🚫 Using Very General Averages Without Adjusting Them – If you have very old appliances (toilets, washing machines) or very efficient ones, or habits that are very different from the average (very long/short showers), the estimate will be less accurate if you don't adjust the data.

Be as honest and detailed as possible when entering your habits for a better estimate.

Comparison: Estimated Calculator vs. Water Bill

What additional information does this calculator give you regarding your monthly bill?

The calculator will estimate your total daily and monthly consumption in liters and cubic meters (m³).

What is this calculator for?

It is used for estimate your domestic drinking water consumption, helping you to:

1. Be aware of how much water you use.
2. Identify the activities that consume the most energy in your home.
3. Get an idea of your potential monthly consumption to compare with your water bill or averages.
4. Discover opportunities to save water and money.

What are the major water consumptions in a typical home?

Generally, the highest consumptions in an average home are:

1. WC (Toilet): Especially older models that use a lot of liters per flush.
2. Shower: Long showers or those with high-flow showerheads use a lot of water.
3. Clothes Washing Machine: Particularly older models or the use of partial loads.
4. Garden Irrigation: It can be a very high consumption, especially in summer.
5. Dishwashing: Leaving the faucet running while washing by hand uses more water than using an efficient dishwasher (generally).

Practical example of estimation for 1 person

Let's estimate the daily consumption for 1 person:

• Shower: 1 * 7 min * 10 L/min = 70 L
• WC: 5 flushes * 6 L/flush = 30 L
• Handwashing: 3 min * 6 L/min = 18 L
• Washing machine (daily proration, e.g.): 10 L
• Kitchen/Other: 15 L
• Estimated Daily Total: 70 + 30 + 18 + 10 + 15 = 143 Liters.
• Monthly (30 days): 143 L/day * 30 ≈ 4290 L ≈ 4.3 m³.

How many liters of water does a shower, toilet, or washing machine use on average in Chile or around the world?

Average values may vary, but as a reference (approximate):

• Shower: A normal showerhead can use 10-15 L/minute. An efficient showerhead uses 8-10 L/min. A 10-minute shower can use 100-150 liters!
• WC: Older ponds use 10-15 liters per flush. Modern ones with double flush valves use about 3-6 liters.
• Washing machine: Older models can use 80-120 liters per charge. Efficient (front-loading) models use about 40-60 liters.

How can I reduce my water consumption at home?

Some key ideas:

• Shorten the length of your showers.
• Install efficient (low-flow) showerheads and faucet aerators.
• Quickly repair leaks in faucets and toilets.
• Use the washing machine and dishwasher only with a full load.
• If you have an older toilet, consider putting a full bottle of water in the tank or replacing it with a dual-flush toilet.
• Don't leave the faucet running unnecessarily (when washing dishes, brushing your teeth, shaving).
• Water your garden early in the morning or late in the evening to reduce evaporation.

How accurate is this calculator's estimate?

Accuracy depends completely dependent on the accuracy of the data you enterIf you accurately estimate your shower times, flushing frequency, etc., and if the calculator uses realistic average flow rates for your country/features, the estimate can be fairly close. However, it will always be an estimate, not an exact measurement.

How can I read my water meter to know my actual consumption?

Locate your water meter (usually outside your home, under a cover). Write down the numbers it displays (usually in cubic meters, m³). Reread it after a period of time (e.g., a week or a month). The difference between the two readings is your actual consumption in m³ during that period.

What is the average water consumption per person in Chile?

According to data from the Superintendency of Sanitary Services (SISS) and other sources, the average consumption of drinking water per person in Chile is around 150 to 170 liters per dayYou can compare your daily estimate per person with this figure.

Do water leaks affect consumption? How can they be detected?

Yes, a lot! A leak, even a small one (a constant drip from a faucet or a quietly running toilet), can waste hundreds or thousands of liters a month, inflating your bill.

• To detect a leak in a toilet: Put a few drops of food coloring in the tank. Wait 15-20 minutes without flushing. If you see color in the bowl, the tank mechanism has a leak.
• To detect general leaks: Turn off all the faucets in the house. Check your water meter. If the dial or numbers keep moving, you have a leak somewhere in your water system.
