Sewer Network Monitoring Sensors

Description

Anglian Water Services (AWS) Limited intends to award multiple framework agreement(s) for the supply of battery powered sewer level monitoring devices and sewer derived flow level monitoring devices with communications to cloud based data centre via MQTT or HTTPS being utilised if MQTT is not available. It is estimated that Anglian Water may require the supply of circa 50-60,000 such devices over AMP8 (2025 - 2030). Delivery will be required to any location within the Anglian Water region. Provision of a platform to visualise data produced by the devices and metadata must be included. Provision of data and licensing must be also included for the life of the devices. Provision of a 3rd party visualisation and analytical tool / platform to ingest API link data is outside the scope. On-site services such as installation and maintenance will be carried out by Anglian Water or a 3rd party delivery route and are therefore also outside the scope of this framework. All monitoring sensor devices must be suitable for deployment within the sewer network. Bidders must be mindful of the harsh environments that these monitoring sensor devices will be installed in. The Equipment and Protective Systems Intended for Use in Potentially Explosive Atmospheres Regulations 2016, UKSI 2016:1107 is a requirement for some locations within Anglian Water's sewer network. The combined monitoring sensor device and platform solutions should support the following communications medium and protocols: • At least one of the following primary methods of communicating back to data collection servers must be either 4G or CAT1 BIS • Serial Comms, Bluetooth or equivalent for local use. Bluetooth must communicate through closed heavy duty (cast, ductile and / or galvanised iron) manhole covers at a range of up to 3 metres. • Communications to cloud based data centre via MQTT or HTTPS being utilised if MQTT is not available. • All devices must support a minimum of at least one form of fall-back safety communication protocol from the following: 4G/2G/ CAT1 BIS. • Devices need to contain a roaming SIM that allows the SIM network to switch from one provider to another - e.g. EE to O2. Options for external antennas should be provided. All monitoring sensor devices must have the ability to identify signal strength for installation purposes and log the signal strength at the successful transmission time. Level data shall be exported into third party systems through REST API or file export. The solution should comply with the following key elements of the specification: 1. 15-minute logging intervals minimum frequency (adjustable from proprietary platform) 2. Range must cover 50mm to >3000mm 3. Ability to Report on Exception. (see 4.8) 4. Minimum Twice daily dial up or exception (adjustable from proprietary platform) 5. Minimum requirement of 5-year battery life (Based on above requirements) 6. Ability to remotely apply false signal suppression 7. Continuous flow measurement principle 8. Easy to install and commissioning -
