5.2 Remote monitoring solutions to urban wastewater management

SolidAT and Holon Municipality, Israel

Located in the centre of Israel, Holon municipality's old sewage system was plagued with problems
such as frequent blockages and overflows. By installing several of Solid Applied Technologies'
(SolidAT) SmartScan 50 non‐contact gauging devices equipped with sensors, the municipality was
able to better control and manage its sewer systems. Additional improvements were achieved due
to the high resistance of the devices to the methane environment, and to the municipality's ability
to receive reliable information and monitor its sewer system using a web platform, and sending
alerts via short message service (SMS) messages when the level reaches low/high limits.

SolidAT offers a variety of level sensors and remote monitoring solutions for sewer level monitoring
and water level monitoring. Further information is available at: http://solidat.com/

Delft‐FEWS and Hollandse Delta Regional Water Authority, Netherlands (pilot project)

In the Netherlands, extensive sewer networks are linked with SCADA. However, systems are not
linked to Wastewater Treatment Plants (WWTPs) nor are they linked together, as each municipality
is responsible for maintenance and operation within its boundaries. The system is vulnerable to
