During the torrential rains expected tomorrow (Friday), you are requested to avoid using dishwashers, washing machines. baths and, ideally, to refrain from flushing the toilet until the rain is heavy but not as heavy as an inch per hour. Our roofs, courtyards, and window wells carry a lot of rainwater into our system. Our basement apartments tend to flood when the city’s sewer mains are overwhelmed by rainwater from the catch basins. The less water we elect to send into the system at such times, the better.
