Take length x width x depth x 6.2 = Holding tank size in gallons. For every 1000 gallons of waste add 1 liter of Pit Renovator.
Double the above amount of Pit Renovator. Before using on over-flown drains, bail out as much water as possible from area. For opening pit drains, pour 1/2 of a pail directly into drain. Allow working time of 1-30 minutes. For drain maintenance use 1/4 of a pail in weekly. Use 1 liter weekly for main drains.
