Yes, water is required of course to keep things flowing. The issue is not the septic tank itself, but how much water the leeching field can absorb at a time. If water's going in faster than it's going out, the level in the tank will rise. This is expected (i.e. TL washer draining) and capacity is calculated into tank size. However, if:
water inflow g.p.m. > tank capacity at start + water outflow g.p.m.
the level in the tank will rise. If it continues there'll be a problem for your basement
Water outfow g.p.m. is not a static number. Day to day it depends on how saturated the leeching field is with water from rain, runoff, etc.
