A: This often asked question is one of the more difficult questions to answer, as there are many variables involved. However, historical data show that savings of up to 30% can be achieved in most cases. Much of these savings are in the reduction or elimination of excavation and backfill cost and the reduction in trenching depths on site. The reduction in number of downpipes and their size also contributes to the lower material costs.
