If you are building a new house and will not be hooked up to the municipal sewage system, then you will need to install a septic tank. A septic system is needed to break down the organic components in sewage before it can be safely released back into the ground. Most areas of the country have requirements and regulations for septic tanks and sewage treatment. Septic tanks come in various sizes to meet a variety of needs. Ultimately, the size of the tank depends on how much water will be going through it. Keep reading learn how to determine exactly what size septic tank you need for your house.
Estimate How Much Water Will Enter The Septic Tank
The first step is to estimate how much water will be going into your septic tank. In order to come to this figure, think about how many people will be living in your new home. Then consider how many people will visit your home. Look at your water bill to see how much water being used in your current household. Consider the age of all your family members. Young kids use a lot more water than adults, who are more conservative. Having kids also typically means more laundry, which uses more water. These situations will increase the demand of your septic system, so you'll need a larger tank to handle that amount of water.
- If your family uses about 400 gallons of water a day, then you should get a 900-gallon septic tank.
- If your family uses about 500 gallons of water a day, then purchase a 1,250-gallon tank.
- If your family uses about 700 gallons of water a day, then you need to buy a 1,550-gallon septic tank.
Consider The Number Of Bedrooms In Your Home
If you are unsure of your family's water usage, then you can base the size of the septic tank you need on the number of bedrooms in your new home.
- If there are 3 bedrooms in your new house, then the smallest septic tank you should purchase is 900 gallons.
- If there are 4 bedrooms in your new home, then buy a 1,250 tank.
- If you have 6 bedrooms, then the minimum tank size you should buy is 1,550 gallons.
If possible, don't solely base the size of the septic tank needed by the number of bedrooms in the house. But do keep it in mind. It's best to base the tank size on the volume of water used, because more than one person often occupies one bedroom and you could easily end up with a tank that is too small.
