Lifetime Costs: The typical total cost for a new septic system over a 20 year period is $6,300 to $13,000 for trenches and mounds, or $13,500 to $32,000 for alternative treatment systems.For multi-household systems, typical trench or mound systems range from $18,500 to $25,000.he typical total cost for a new septic system over a 20 year period is $6,300 to $13,000 for trenches and mounds, or $13,500 to $32,000 for alternative treatment systems.
According to the University of Minnesota, typical yearly costs for a mounded septic system might run as much as $500 as of the time of publication, including the costs of replacing pumps in these systems.he higher cost is necessary, however, if the site or soil condition makes it impossible to use a subsurface soil absorption system, according to the OSUES. Although installation costs vary depending on septic size and location, a mounded septic can run between $30,000 to $50,000 to construct.
