We commonly find that wet pits that have sump wells the wells are always at the highest point so the water pools away from the well. So the first trick we try is to drill holes in the sides and bottom of the sump wells. This gives the water a -place to drain at the lowest possible point. And its right where you want it. This works most of the time. If that doesn't work we then have gutters cut in the pit floor to direct the water to the sump well.
