Commercial Septic Tank Services in Tacoma
Helping You Select the Right Septic Tank for Your Business
Sizing for septic tanks and drain fields is much different for commercial establishments as opposed to residential. There are many more variables to take into consideration such as what type of facility your system is accommodating, how many visitors it will receive per day, and what types of activities will be taking place.
There are many codes that determine what size of septic field and tank will be permitted on any given property. When deciding what size drain field and tank you will need, you must keep in mind that the amount of water and waste flow will typically not be uniform day to day.

Other Factors to Consider in Getting a Septic Tank
Installing a septic tank is a big decision that needs careful consideration. In addition to the type of your facility and purpose of the septic tank, other factors should also be weighed in to ensure that you’re getting the right fit for your commercial properties.
These other factors include:
- Soil percolation rate- This is measured in minutes per inch and will determine how well the soil in your drain field will filter your wastewater.
- The number of expected occupants- This will give you a decent idea of how many gallons of wastewater per day will be passing through your system.
- The number of linear feet your drain field will need- This is based on how much projected wastewater you are expecting to flow on any given day.
Great care should be taken when determining these factors. Any miscalculation could lead to overflows of the system which is a danger to people and extremely hazardous to the environment.
How Septic Tanks Work
Typically, a septic system will consist of one or more plastic or concrete tanks with a capacity of 4000 to 7500 liters. While one end is connected to an inlet wastewater pipe, the other is connected to a septic drain field. Wastewater will enter through the first chamber of the tank. This allows the solids to settle and scum to float.
Once the solids are settled, they are broken down with anaerobic digestion. This will reduce the volume of the solids making them easier to manage. Any liquids are sent through to the second chamber, where another instance of settling takes place. Excess liquids are drained through the outlet into a septic drain field.
In order to make sure the soil is correct for a drain field to take place, you must first perform what's called a percolation test to determine the absorption rate of the soil and ensure that it will drain correctly.
If the soil is correct for draining, any remaining impurities will be trapped while the excess water is eliminated through percolation, evaporation, and into the root systems of plants. A network of pipes will distribute the wastewater via multiple holes into the drainage field.
While some septic systems can operate by gravity alone, others may require the application of a lift pump. With a properly designed septic system, there should be no odor at all. In addition, with regular emptying and maintenance from your Tacoma plumber, your septic system should last for decades without needing to be replaced.
Emptying Your Septic Tank
Some waste that enters the septic system will not be broken down. This means that it must eventually be removed from the septic tank. Otherwise, material that has not been decomposed will leak directly into the septic field. Not only is this extremely harmful to the environment, but may lead to complications by clogging the pipe leading into the septic field. This may also lead to a decrease in how well the soil drains which will require expensive repairs to amend. When excess sludge is removed from the tank, it is done so via a vacuum truck.
How often your tank needs to be emptied depends on a few different variables such as:
- Volume of the tank relative to the input of solids
- The amount of indigestible solids
- The ambient temperature
- System characteristics
- Requirements of the relevant authority
While some tanks require pumping every few years, others only need to be pumped every 10-20 years. The anaerobic decomposition is resumed as soon as the tank is refilled.
