What Size Cistern Water Tank do I need?

Any time you are looking to add a cistern tank to you home, business, or industrial location, one of the most common questions asked is, "What size cistern tank do I need?". While the answer can vary based on your location, tank and supply requirements, some general information on sizing your tank can be found below.

 

Water Consumption

One of the first steps in determining your water requirements is determining the amount of water used in your location. To assist customers with this process, we urge them to check out the Water Consumption Calculator. This calculator takes the amount of people, faucets, and toilets in your location and then calculates your approximate water usage.

Depending on how you are looking to use your collected rainwater, different fields may be more applicable than others. For example, if you are looking to reuse rainwater exclusively for sprinkler systems, you may require different options than if you are looking to supply your entire home with water.

  • Number of People in your Residence
  • Daily Showers (average time in shower, shower head flow)
  • Toilet Water Use (number of toilet uses, gallons per flush)
  • Faucet Water Use (average number of faucet uses, minutes per use)
  • Dishwasher Uses (by hand numbers, gallons per dishwasher)
  • Laundry Uses (amount of loads, gallons per load)
  • Lawn Water Uses (how many times is the lawn watered, minutes per watering)

The second step in sizing your cistern tank involves your collection area and collection method. For example, if you are planning on collecting rainfall from your roof, you will need to determine the size of the roof collection area. This will help determine how many gallons you can expect to collect from your given method. Some things you will need to consider includes the following:

  1. How you will be collecting rainwater
    Typical collection methods will include rainwater catchment from the roof, downspouts, gutters or even straight into your open top tank.

  2. Available collection area
    The size of the collection area can help you determine how much water you can except to catch in a given area.

  3. Amount of rainfall in your area
    The next step in the process is determining how much rainfall you can expect in your area. For this process, you will want to look at both the average rainfall amounts, as well as the normal rainfall amounts for your specific area.

Cistern Tank Types

After you determine how much water you will need, the next step is choosing the right cistern tank for your location. Factors you will need to take into consideration includes storage area (space restrictions, above ground, below ground) and size. Some common options include:

Fiberglass Tanks: The fiberglass storage tank is a favorite for rainwater collection due to its strength and stability. Fiberglass tanks will not rust or corrode, making them ideal for long-term storage applications.
corrugated tanks Corrugated Steel Tanks: As an alternative to standard steel, corrugated steel tanks are also available for rainwater storage and collection. These tanks will ship in pieces and then are installed on site.
steel water tanks Steel Tanks: Another common option is a steel storage tank. These are available in both above ground and below ground options and can accommodate water storage requirements up to 50,000 gallons.
Pillow Cistern Tanks: For small scale storage, rainwater pillow tanks are a great option. These tanks are often implemented in crawl spaces, basements, or under decks to provide low profile storage.
