Santerra Green FlushSmart V Series Systems are the most advanced environmental toilet system available today. A modern-looking vacuum flush toilet, in choice of two styles, uses as little as 0.2L of water/flush to the remote composting unit. Gravity is not required, making it ideal for slab-level installations (basements, cottages on rock, work shops). Can flush up, down & around corners up to 70’ away! Pulverizes waste before it reaches composting unit for even greater efficiency. Double tank models offer high capacity option.
