Low Impact Development (LID) solutions system called Drainage Block

Objective:

This invention is a Low Impact Development (LID) solutions system called Drainage Block that is effective for retention of rainfall on paved areas in average as well as in extreme conditions. The system is developed for roof runoff but the general idea can also be applied to delay runoff from roads parking lots and in small canals. The Drainage Block is very well applicable in a modular system. Modular application in large paved areas will create nearly endless possibilities to spread the runoff from rainstorm events. Simultaneous application of a wide range of delaying capacities of the Drainage Block in a modular system will extend the runoff spreading even more. This is applicable both as different Drainage Blocks in a single area and as similar Drainage Blocks on different areas that runoff to the same drainage system. The Drainage Block can also be applied to improve water harvesting and to create a much larger base flow that is required for beautification of urban canals. Technology Features: (1) Large reduction of peak flow and large delay of runoff and thus a large runoff spread (over time) for moderate as well as for extreme rainstorm events. (2) Large flexibility in delaying capacities (3) Simple concept (4) Low need for maintenance (5) Applicable for water purification techniques (6) Modular construction Applications: (1) Storm water retention and control (2) Water management Patents: Pending patents - US provisional patent application Opportunity: Exclusive/ non-exclusive licensing; Partnership in commercial development

Benefits:

(1) The drainage block is effective than existing solutions in both large reduction of peak flow and large delay of runoff and thus a large runoff spread (over time) for moderate as well as for extreme rainstorm events (2) Large flexibility in capacity to delay a wide range of rainwater flow (3) Easy maintenance (4) Modular application in large paved areas
