7-10 years isn't long. Around here there are many 40 year old fields and 20-30 years is the normal expectancy. Many systems have pump up systems like mine. I have a holding tank, then a pumping chamber that pumps up to the field.
I too however don't want to reduce the life span any on my field. Ironically, the soil (at least the grass) over the leach field (The whole mound) is the hardest in my lot as the lower parts of my lot stay soft due to a fairly high water table.
