Why Spreading Out Water Usage Protects Your Septic Tank

Excessive water use doesn’t just increase your water bills—it can also wreak havoc on your septic tank. Many septic system owners do not realize that too much water use can directly impact the tank. Excessive water released into a septic tank can overwhelm the system and lead to system failure, backups, slow drains, and foul odors around the area. You can dodge most septic tank issues with spreading out water usage. Read on to learn more on why spreading out water usage protects your septic tank.

  • Allows For Solids Separation

A septic tank functions on retention time. It needs enough time to sort raw sewage into distinct layers. Heavy solids have to sink to the bottom while lighter materials rise to the top. If water moves through the tank too fast, it will sweep these suspended solids out with it. A steady, spaced-out flow keeps the middle layer clear for treated wastewater to safely exit to the drain field. Therefore, spreading out water and installing water-saving fixtures usage keeps your septic tank working properly and extends its lifespan. If you notice a problem with solids separation despite being careful with water usage, it could indicate a problem inside the tank. Call a trusted septic company to perform an inspection and make the necessary repairs.

  • Prevents Drain Field Flooding

One of the common misconceptions surrounding drain field use is that this component has an unlimited capacity when it comes to absorbing effluent discharged from the septic tank. Nothing could be further from the truth. A standard drain field typically handles between 400 and 600 gallons of wastewater a day. Exceeding this limit comes with several consequences, including saturating the soil and forcing the solids out of the tank. You may end up with sewage backups, standing water in the drain field area, and slow drains.

This is why septic service providers recommend that you spread out water usage throughout the week rather than doing it all on one day. It gives the drain field enough time to disperse the effluent from the tank, thereby preventing hydraulic overloading. Other measures you can take to keep excess water out of your drain field include diverting surface water away from the drain field area. It’s also a good idea to schedule regular septic pumping to give the saturated soil time to rest and dry out.

  • Extends the Life of the Septic System

Replacing a septic system can be a significant expense running into thousands of dollars. Fortunately, many septic failures can be prevented through proper maintenance, regular septic cleaning, and responsible water usage habits. Reducing stress on the septic tank and drain field allows the system to function more efficiently for a longer period. Homeowners who spread out water usage often experience fewer repairs, lower maintenance costs, and a longer-lasting septic system.
