Budgeting for a system in Manassas city, VA
Without a countywide reading for Manassas city, both cost ranges below are worth knowing before a test, not just one. Conventional systems typically run $3,000-$8,000; where the soil doesn't allow one, engineered alternatives run $10,000-$40,000. A perc test decides which range applies.
