Cesspools are cylindrical holes in the ground lined with stone or concrete and designed to hold a property’s wastewater. Though similar to septic tanks, cesspools don’t treat incoming material. In this guide, you’ll learn about how to determine if your house has a cesspool and why you may need a septic installation service to provide you with a tank.

What to Know About Cesspools In Hawaii

Hawaii has about 88,000 cesspools, which is the most of any state. Since these containers don’t treat the wastewater, the toxic liquid can seep through small cracks in the mortar and enter the soil. From there, it can affect groundwater, potentially tainting drinking supplies. Nitrogens and other elements from the wastewater can also travel to nearby ponds or the ocean. This can upset the delicate balance within these aquatic environments, causing harm to structures like coral reefs.

In 1992, Oahu passed a law banning the building of new cesspools. Additionally, according to Act 125 in 2017, all existing cesspools must be upgraded to septic tanks by 2050. If your property has one, you’ll eventually need to order a tank from a septic installation company.

How to Find a Cesspool on Your Lot

One of the easiest ways to determine whether or not your property uses a cesspool is by looking up the year of construction. If your home was built before 1992, it’s likely that it has a cesspool.

Since building codes require them to be at least 10 feet from the exterior walls, check the perimeter for a circular metal or cement covering about three feet in diameter. Some properties have more discreet cesspools, especially those built on slabs, so you may need a professional to look beneath the house.

After the septic installation, have your new tank maintained by ABC Cesspool and Septic Pumping in Kamuela, HI.
