A drainage system includes a storm water chamber and riser assembly for gathering and dispensing liquids. The storm water chamber comprises a generally elongated arch shape with an arch top and bottom side walls, thereby defining an enclosure. The riser assembly has two generally parallel base assemblies, which each have an outer wall and an inner wall and a top wall connecting the outer wall and the inner wall. The top wall has a chamber seating area for receiving the base area of the chamber and a retaining element for retaining the base area of a chamber in position in the chamber seating area.

1. A drainage system, comprising: a elongated arch shaped chamber having a base area at its lower end; anda riser assembly having two generally parallel hollow base assemblies, each said base assembly having an interior hollow space, each said interior hollow space being defined by an outer wall and an inner wall and a top wall connecting the outer wall and the inner wall, the top wall having an chamber seating area for receiving the base area of the chamber and a retaining element for retaining the base area of a chamber in position in the chamber seating area, one or more hollow connecting struts extending between the inner walls of the base assemblies and providing liquid transfer between the base assemblies. 2. The drainage system of claim 1, wherein each base assembly has a lower end and the interior hollow space is open at its lower end. 3. The drainage system of claim 1, wherein each base assembly is provided with reinforcing ribs in its inner wall, or its outer wall, or in both its inner and outer walls. 4. The drainage system of claim 1, wherein the retaining element of the base assembly includes a rail located along the top wall above the outer wall of the base assembly. 5. The drainage system of claim 4, wherein the retaining element of the base assembly is a pair of rails located along the top wall above the outer wall and inner walls of the base assembly. 6. The drainage system of claim 1, wherein the connecting struts are two diagonal struts which cross each other to form an X-shaped support. 7. The drainage system of claim 1, wherein one end of each of the base assemblies of one riser assembly is adapted to overlap and seat on the other end of each of the base assemblies of a horizontally adjacent riser assembly. 8. The drainage system of claim 7, wherein a plurality of riser assemblies may be connected together by overlapping one ends of the base assemblies with the other end of base assemblies. 9. The drainage system of claim 1, wherein the riser assembly has no end walls, one end wall, or two end walls. 10. The drainage system of claim 1, wherein the inner wall of at least one base assembly is provided with a plurality of holes. 11. The drainage system of claim 1, wherein the riser assembly is nestable and stackable with additional such riser assemblies for shipping or storage. 12. A riser assembly having two generally parallel hollow base assemblies, each said base assembly having an interior hollow space, each said interior hollow space being defined by an outer wall and an inner wall and a top wall connecting the outer wall and the inner wall, the top wall having an chamber seating area for receiving a base area of a chamber and a retaining element for retaining the base area of a chamber in position in the chamber seating area, one or more hollow connecting struts extending between the inner walls of the base assemblies and providing liquid transfer between the base assemblies. 13. The riser assembly of claim 12, wherein each base assembly has a lower end and the interior hollow space is open at its lower end. 14. The riser assembly of claim 13, wherein each base assembly is provided with reinforcing ribs in its inner wall, or its outer wall, or in both its inner and outer walls. 15. The riser assembly of claim 14, wherein the retaining element of the base assembly includes a rail located along the top wall above the outer wall of the base assembly. 16. The riser assembly of claim 15, wherein the retaining element of the base assembly is a pair of rails located along the top wall above the outer wall and inner walls of the base assembly. 17. The riser assembly of claim 12, wherein the connecting struts are two diagonal struts which cross each other to form an X-shaped support. 18. The riser assembly of claim 12, wherein one end of each of the base assemblies of one riser assembly is adapted to overlap and seat on the other end of each of the base assemblies of a horizontally adjacent riser assembly. 19. The riser assembly of claim 18, wherein the riser assembly has no end walls, one end wall, or two end walls. 20. The riser assembly of claim 19, wherein the inner wall of at least one base assembly is provided with a plurality of holes. 21. The riser assembly of claim 20, wherein the riser assembly is nestable and stackable with additional such riser assemblies for shipping or storage. 22. A method of installing a drainage system, comprising: positioning a plurality of riser assemblies, each said riser assembly having two generally parallel hollow base assemblies, each said base assembly having an interior hollow space, each said interior hollow space being defined by an outer wall and an inner wall and a top wall connecting the outer wall and the inner wall, the top wall having an chamber seating area for receiving a base area of a chamber and a retaining element for retaining the base area of a chamber in position in the chamber seating area, one or more hollow connecting struts extending between the inner walls of the base assemblies and providing liquid transfer between the base assemblies;said plurality of riser assemblies being positioned in an end-to-end fashion by overlapping and seating one end of each base assembly on the other end of base assemblies of an adjacent riser assembly;positioning a plurality of elongated arch shaped chambers having base areas at their lower ends in the chamber seating areas of the riser assemblies.
