How much does a lagoon septic system cost?
Also know, how much does it cost to put in a lagoon?
The average cost of a lagoon system installation for a small home was $2,426. To install a septic tank system for a large home cost $5,558, on average. An average installation of a lagoon system for a large home was $2,631.
Similarly, do you need a septic tank with a lagoon?
A residential lagoon system may use a conventional septic tank, but effluent from the tank flows to a storage pond or lagoon for further treatment. (Some states such as Missouri may permit a lagoon without a septic tank.)
Although costs vary according to the size of the leach field, soils and costs of local permits, expect to pay between $5,000 and $20,000 for leach field replacement. It is the most expensive component of the septic system.
