Septic Tank Installation & Replacement FAQs
Practical answers for Concord homes and businesses.
Is every Concord system aerobic?
No. Conventional and chamber fields are options where suitable. Pumps distribute effluent; aerobic treatment is a separate treatment process.
Does a bigger tank solve poor soil?
