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.
1 Mound System-A mound septic system cost will depend largely on the slope and grade of the property, and these systems can cost from $9,000 to $25,000 or more. 2  This type of system can have many variables which can affect the cost you will pay. Evapotranspiration System-The septic system cost for this system type is high, and will start at about $25,000 and go up from there. 2  This septic system is ideal for desert areas but not many other locations, and that is one reason why the cost may be so high.
