How to calculate water bills at home

The calculation of water bills in a household can be done by multiplying the actual amount of water used by the water rate set by the utility, which may vary depending on the amount of water consumption or the billing system in different areas (tiered water pricing). Here are the methods for calculating water bills and tips for reducing water expenses in the home:

How to calculate water bills at home

1. Check the water meter

• Start by checking the water meter to see the amount of water used each month. The amount of water used will be measured in cubic meters (m³), which can be viewed on the meter or the bill.
• Typically, 1 cubic meter (m³) is equivalent to the use of 1,000 liters of water.

2. Calculate the water usage fee based on the water service rate

• Many cities or communities use a tiered water pricing system, meaning that if you use more water, the price will increase accordingly.
• For example (prices may vary by area and plumbing):
  • 0-10 m³: 10 Baht/m³
  • 11-30 m³: 12 Baht/m³
  • 31 m³ and above: 15 Baht/m³

How to reduce water expenses at home

There are several ways to reduce water costs that help decrease water usage effectively.

1. Use water-saving tools

• Install water-saving showerheads and faucets: Showerheads designed to use less water can significantly reduce water usage in the bathroom.
• Use water-saving fixtures: such as water-efficient toilets or washing machines that use an appropriate amount of water.

2. Reduce unnecessary water usage

• Turn off the water when not in use: Turn off the water while brushing your teeth, washing dishes, or cleaning to save water.
• Use a rainwater collection barrel: If you have a garden or outdoor space, you can collect rainwater to use for watering plants or cleaning the area.

3. Use energy-efficient appliances

• Water-saving washing machines: Choose washing machines that have water-saving systems, especially those that can wash with less water.
• Efficient dishwashers: Some models of dishwashers can use less water for cleaning.

4. Check for water leaks

• Check for Leaky Pipes: Sometimes, leaks in water pipes can lead to increased water usage without us realizing it. It is advisable to check and repair any leaking pipes or faucets to prevent water loss.

5. Adjust water usage methods in various activities

• Watering plants: Water at the right times, such as in the morning or evening, to avoid excessive water loss from evaporation.
• Washing laundry or dishes in large quantities: Instead of washing small loads, you should wait until the washing machine or dishwasher is full before using it to make the most of the water used.

6. Use a water circulation system in the house

• Using a Greywater Recycling System: If possible, using a recycling system for water from laundry, showers, or dishwashers can be utilized for watering plants or flushing things without the need for new water.

Summary

The calculation of water bills in a household depends on the actual amount of water used and the service rates of that area. There are several ways to reduce water costs, such as using water-saving devices, reducing unnecessary water usage, and regularly checking for leaks. Choosing these methods can effectively reduce water expenses in the long run.
