Many times after a large storm that brings a lot of rain, there is a lot of pressure on sewer systems from all of the storm water. Also, electricity outages can mean the loss of power at some pump stations. After a hurricane, you may be asked to limit usage to sanitary use only —that means strictly limiting or not doing laundry, taking only very short showers, no watering your lawns, and limiting dish washing or any other activity that sends a lot of water down the drain and into the sewer system. To prevent back-up into homes, conservation is a good option. Only use your water for what is necessary until the systems can get back to normal after the storm. This is also another good reason not to rush back home after the storm.
