Abstract: Now a day’s drainage blockage is the major cause of pollution and flooding in the Metro manila cities. Because of these people in Metro cities faces no. of problem such as bad impact on human health and also causes of accident. We have designed the drainage blockage detection system to avoid such problems. This system provides monitoring of drainage condition and to inform authorities of these condition. This design present an implementation wireless sensor network in the monitoring of drainage system using GSM system. To detecting blockages and monitoring water level condition we use level sensor. This design consist of GSM module is used to send the messages to central computer and monitors all drainages throughout the area.
