All of our 12x12 Packages come with the included basin (fully enclosed with outlet cut out options already in the basin) and the included grating which is selected. Basket for debris removal is available as well for sediment trap.
What size outlets are on the basin?
Each 22x22 (actually all of our basins) come with pre designed cut outs for pipe connections. The 12x12 basin has a 6, 8, 10 and 12 inch outlet cutout option. We recommend using a hole saw for easy removal of the inner portion of the attachment. Then you simply slide your pipe on - seal with Standartpark Professional sealant and you are all done. Outlet connections are located on ALL FOUR sides of the basin - but the basin itself comes completely enclosed - making it perfect for a sump pit as well.
