Water utilities worldwide are on a mission to combat non-revenue water, which causes soaring costs, service disruptions, unhappy customers and wastes our most precious resource. In Australia and New Zealand, most utilities are exploring the game-changing potential of digital metering (DM). While DM brings efficiency gains and customer engagement, it falls short in identifying physical network leaks. Enter Sotto® (Sotto): the groundbreaking leak detection sensor created and proven by South East Water (SEW) in Melbourne.

By integrating Sotto into DM deployment at a marginal cost, SEW achieved early leak detection, thereby reducing water loss. SEW conducted a successful trial using 5,000 Sotto-enabled digital meters, leading to early leak detection with financial viability.

SEW engaged ÍøÆسԹϺÚÁÏÒ»Çø¶þÇøÈýÇø to review their findings and model a 1:1 or 1:2 density of Sotto sensors to save water effectively. You can read more about the benefits of Sotto and ÍøÆسԹϺÚÁÏÒ»Çø¶þÇøÈýÇø' analysis by checking out the case study below.
