Did you know that the first septic tank in the United States was installed in 1876? We’ve had these tanks since then but it was only in 1905 when baffles, which were made of oak boards, were added in the system to regulate the flow of sewage. And by the 1920, septic tanks were already common and essential features of properties, whether commercial or residential. Read on and learn more about septic system design!
Septic Tank Size
Nowadays, most jurisdictions require a minimum capacity of 1,000 gallons. However, to prevent overflows and backups, it is recommended to add a few more gallons. For instance, if you have three bedrooms at home, instead of installing a 1000-gallon tank, install one with a 1,350-gallon capacity. To ensure that you’ll pick the right size, consult a licensed plumber.
Septic Tank Make
Approved septic tanks can be made from fiberglass, concrete or polyethylene. As long as it is properly installed, any of these materials will do. If a lightweight tank will be used for the property, it must be anchored to keep it from floating up when it’s empty.
When choosing the site for the tank, you must remember that you should follow a number of important guidelines in terms of clearances for buildings, wells and other types of structures. Since the tank will hold waste materials that are detrimental to one’s health, it must be placed in a safe distance away from these structures. Once again, let your plumber choose the best location for the installation. This way, you’ll surely comply with your local codes.
Just as there are recommended sizes for septic tanks, there are recommended sizes for drainfields. The typical trench size ranges from 2 to 5 feet, as per USDA. The trench length, meanwhile, is usually set at 100 to 150 feet. The bottom line is, it depends on your installation site and the condition of the soil. There are other elements to take note of in terms of drainfield size but we’ll tackle those some other time.
Effluent Retention Time
The septic tank’s effluent retention time is important, too. Tanks should be pumped out regularly to prevent clogging and avoid malfunction. Remember, when the septic tank clogs, wastewater may back out of your drains and your clean water may get contaminated, too.
Soil PERC Test
PERC tests should be done in order to analyze the condition of soil when the septic tank fails or prior a tank installation, repair or replacement. Take note that the PERC test is different from the deep hole test pit. Also remember that there are also PERC hole specifications that should be followed. Again, we will talk about these another time.
