i2O Water provides Smart Pressure Management solutions for water utilities around the world, currently saving over 235 million liters of water every day. Our SaaS software utilizes the Apache Cassandra NoSQL database to store time-series data from devices interacting with the software and intelligent learning algorithms analyzing that data. We record network topology changes over time as new zones/devices are managed and store large amounts of spot events such as alarms and warnings about faulty assets.
