Anglian Water has gone out to tender with a major AMP8 contract for sewer level network monitoring sensors worth an estimated value of £140.4 million (inc VAT).

The water company intends to award multiple framework agreements 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).
Anglian Water estimates that it may require the supply of around 50-60,000 of these devices over the course of AMP8 between 2025 to 2030).
Other requirements include:
- provision of a platform to visualise data produced by the devices and metadata
- provision of data and licensing for the life of the devices
However, 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 will also be outside the scope of the framework.
All monitoring sensor devices must be suitable for deployment within the sewer network – the utility is pointing out that bidders “must be mindful of the harsh environments” that the monitoring sensor devices will be installed in.
The combined monitoring sensor device and platform solutions will also be required to 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.
Anglian Water is also specifying that options for external antennas should be provided and that 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.
Currented estimated dates that the contract will run from are 2 October 2025 to 1 October 2027, with possible further extension options up to 1 October 2031.
Deadline for enquiries about the contract is 6 April 2025 and deadline to submit requests to participate is 11:00pm on 13 April 2025. All interested parties must complete the Request for Information questionnaire before the deadline for requests to participate.
