Transfer blackwater to wastewater systems or away from low-lying areas by selecting a sump pump, effluent pump or sewage pump from Grainger. Grinder pumps reduce sewage to a finely ground slurry for pumping into elevated septic or sewer destinations. Similarly, a septic effluent pump moves septic fluids free of solids to a drain field with greater durability than a sump pump. Keep wastewater moving with the right pump from Grainger.
