hey guys im looking for the proper technic for this job i have to bid on. we r installing a 380 sq paver walkway. the one part of the walkway is the lowest part of the yard and the soil is graded to this area. the street and every other part of the yard is higher than this area. im thinking on making a large 4x4x4 dry well system here that has 2 gutter downspouts connected into the system. installing a 1/2 hp submesible pump 2ft from the bottom of the system and connecting the pvc line with a check valve. the rise to the street is 2 ft and the run is 60 ft. right infront of the check valve i wanna drill a hole and wrap it in weed fabric with a mini gravel pit there so no water is in the line. how do this sound? is there a website that can help me on this?
