**Short answer:** Yes. Spot laundry detergent sheets are grey-water and septic safe, and they dissolve completely in under 60 seconds, so nothing solid reaches your tank. Earth Breeze, Seventh Generation and HeySunday sheets are septic safe too. For the healthiest system, dose to the load and spread laundry across the week.
