Is it possible to size a tank based on seasonal use?

Understanding Seasonal Water Demand

To size a water pressure tank for seasonal use, you need to determine the average daily water demand during both peak and low periods. For example, if you live in an area with a dry season, you may use more water during the summer months for irrigation. In contrast, the winter months may see significantly reduced water use.

Calculating Peak and Low Period Demand

Calculate the average daily water demand during peak and low periods. For instance, assume a household uses 500 gallons per day during the peak summer months, but only 200 gallons per day during the winter months. To size a tank, you’ll need to choose a tank that can handle the higher demand, typically the peak period.

Sizing the Tank for Seasonal Use

A general rule of thumb is to size the tank for 1-2 days of peak water demand. Using the peak summer demand of 500 gallons per day, a 1-day storage tank would be 500 gallons, and a 2-day storage tank would be 1000 gallons. This will ensure that the tank can handle the increased demand during peak periods, even if it’s not as large as it would be for a single day of peak demand.
