Single Compartment Septic Tanks

Affordable and Reliable Wastewater Solutions
Looking for a simple, affordable, and durable solution for your property’s wastewater management? Single compartment septic tanks are the perfect choice for smaller households, cabins, or rural properties with low daily water usage. Designed with a single chamber, these tanks separate solid waste from liquid effluent through natural settling, with clarified effluent flowing into the drain field for final treatment....

Single chamber septic tanks are also a great option if you’re only directing greywater to your septic system. Since greywater doesn’t contain solid waste, there’s no need for a two-compartment tank, making this a cost-effective and efficient choice for properties with separate blackwater and greywater management. Our single compartment tanks come from trusted manufacturers like Snyder Industries, Norwesco, and Chemtainer, ensuring top-notch quality and durability. With capacities ranging from 500 to 1500 gallons, these septic tanks are designed to suit a variety of property sizes and needs.
