ALL SEWERS OF VARYING DIAMETER SHALL BE GRADEDOBVERT TO OBVERT WHEN THE SEWERS ARE IN LINE.

CASE 1. WHEN D-d IS EQUAL TO OR LESS THAN D/3 ie. (D-d ≤ D/3) THEN THE OBVERT OF THE SIDE BRANCH SHALL BE GRADED TO THE OBVERT OF THE MAIN SEWER.CASE 2. WHEN D-d IS EQUAL TO OR LESS THAN D/3 + 230, BUT GREATER THAN D/3 ie. (D/3 + 230 ≥ D-d > D/3), THEN THE OBVERT OF THE SIDE BRANCH SHALL BE GRADED TO THE OBVERT OF THE MAIN SEWER UP TO THE MAINTENANCE HOLE WALL AND THEN THE CHANNEL THROUGH THE BENCHING SHALL BE GRADED TO D/3 OF THE MAIN SEWER.

CASE 3. WHEN (D-d) - D/3 IS GREATER THAN 230, THE OBVERT OF THE SIDE BRANCH SHALL BE GRADED TO THE OBVERT OF THE MAIN SEWER AND A BACKDROP JUNCTION SHALL BE USED TO BRING THE SIDE BRANCH FLOW INTO THE MAIN SEWER AT D/3.

CASE 4. WHEN (D-d) - D/3 IS GREATER THAN 230, THE SIDE BRANCH SHALL FIRST BE GRADED TO MEET THE MAIN SEWER AT OBVERT LEVEL, THEN: (a) THAT SECTION OF THE INCOMING LINE FROM THE FIRST BRANCH SEWER MAINTENANCE HOLE TO THE MAIN SEWER SHALL BE REGRADED SO THAT THE SIDE BRANCH SEWER HAS AN ENTRANCE DEPTH OF D/3 OR: (b) THAT SECTION OF THE INCOMING LINE FROM THE FIRST BRANCH SEWER MAINTENANCE HOLE TO THE MAIN SEWER SHALL BE REGRADED SO THAT E.L OF WATER SURFACE IN THE SIDE BRANCH IS EQUAL TO E.L OF WATER SURFACE IN MAIN SEWER FOR AVERAGE DAILY DRY WEATHER FLOWS.
