Each section has a â¿¿berm drainâ¿¿, which catch the water coming down from the slope face immediately above and from the berm itself. At the top of the slope, there is a â¿¿cutoff drainâ¿¿. The drain at the very top of a slope to intercept and safely carry away all water coming from areas laying above, including that from the property above.
