If a partial load of sludge is removed, the volume of sludge shall be determined by the use of the Contractor furnished dipstick or sight-glass. All readings taken by Water Treatment Plant Operators will be rounded off to the nearest 25 gallons and accomplished with the truck parked on reasonably level ground.
