Part of the problem was that the Jamaica Water Company's wells were contaminated by chemical spills. Jamaica was switched over to city water. Wells that had been in use for a hundred years were no longer being pumped and the water table rose to its natural level.More ground water is getting into the storm sewers and they have less capacity for storm run-off. Catch basins along Hillside overflow even if they are not clogged. Sometimes water comes out of the sewer grates instead of going down. The street floods over the curb and water runs into the subway ventilation grates and the station stairways. The subway pumps are designed to pump into the storm sewers which are already full. Raising the ventilation grates on Hillside and rebuilding the stairways so that you go up one or two steps before you go down does seem to have helped to keep water out. There was a proposal to buy some land on Hillside and build a big tank for the subway pumps to pump into but nothing seems to have happened yet. |
