SeWatch - wastewater and sewage wireless monitoring system...Manholes...haha
SeWatch™ - The wastewater monitoring system network from Telematics Wireless, provides a wireless system-wide reporting solution for CSO (Combined Sewer Overflow) and SSO (Sanitary Sewer Overflow) discharge or overflow.
SeWatch™ SCADA technology monitors and handles discharge of untreated water, sewer, storm water, waste water, solids or sludge, all along municipal ,industrial or any domestic sewage network.
SeWatch™ system makes sewer treatment easier and cheaper, keeping enviroment cleaner.
SeWatch™ SCADA includes:
Water-level sensors for sewer system manholes.
Remote Terminal Units (RTU) for data capture with built-in wireless communications.
Primary battery or solar-powered wireless relays/nodes, reader/gateway unit for interfacing to a Network.
A monitoring and Controling Management application running on PC or server, which alerts on screen or via SMS about manhole overflow and spillovers.
How SeWatch™ works?

SeWatch™ sensors
The Wastewater monitoring system network from Telematics Wireless, provides a system-wide solution which includes: water-level sensors for sewer system manholes connected to Remote Terminal Units (RTU) for data capture with built-in wireless communications, primary battery or solar-powered wireless relays/nodes, reader/gateway unit for interfacing to a Network, and a Monitor and Control Management application running on PC or server.
SeWatch™ wireless in-manhole units (RTUs)
The sewer-located units (RTUs) are battery-powered. This reduces cost dramatically by not requiring any electric cabling through the sewer system and enables rapid implementation of the system. The installation does not require any modification of the manhole cavity or the cover. The communications network and the RTUs, broadcast over unlicensed ISM bands which do not incur airtime charges. With manhole cover closed, RTU transmissions reach wireless relays at a distance of several tens of meters.
SeWatch wireless Relays/nodes
System wireless relays constitute the backbone of SeWatch network. Depending on the deployment conditions, relays are powered either by primary battery that last for several years, or by solar-powered battery (see picture). The network can be easily expanded to incorporate additional sewers. When a wireless node in a new part of the sewer system is added, it automatically connects to the wireless network, seamlessly integrating into the existing network topography. It sends its data to the network management control server at the Network Operations Center (NOC). If a malfunction occurs at one of the wireless nodes, an alarm is sent to the NOC informing the shift manager of the problematic network element.
The network transmits real-time information about the status of the sewer system section. The network contains self-testing elements to ensure constant communication, and identification and reporting procedures which are monitored at the NOC.
The specific configuration of the Wireless relay/node and Wireless Reader/Gateway depends on the deployment topology, e.g. distance between the wireless nodes, readers etc.
Thus the Network backbone configuration can either be a wireless mesh network of the nodes,
or a wide-area star-type communication network:
In the mesh configuration, wireless nodes communicate with each other to relay the data to the closest Gateway. From there it is further distributed via public (GPRS) network. In this configuration, solar-powered nodes are used due to the “heavy” relayed traffic. In the star-type configuration, each wireless relay communicates directly with one of the network’s readers, strategically spread over the coverage area. These readers are further interfaced with GPRS network to deliver the data to the NOC.
Network Operations Center (NOC)
The server at the Network Operations Center enables graphical display of the dynamic picture of the water levels throughout the sewer system pipes and manholes, with warnings of any problems or unusual readouts. concering water or wastewater overflow or discharge.
Every system alarm, including warnings that are defined as serious, is shown on the screen and can optionally be sent to shift managers and technicians via SMS text messaging service.
