This 18" x 30" Sump and Sewage Basin provides a solution for sump pumps and sewage ejector systems. Designed to be installed below ground level, the basin collects wastewater or groundwater before it is pumped away from the structure, helping manage drainage in basements, utility rooms, and other low-lying areas. With a 30 gallon capacity, this basin offers ample space to accomoodate pump systems while providing sufficient holding volume for wastewater or drainage before discharge.
