The Department of Environment, Food and Rural Affairs has issued a preliminary market engagement notice setting out its intention to establish a new framework for the supply of hydrometric data loggers capable of cardinal point logging functionality for use by the the Environment Agency.
The framework will include after sales technical support and cover the supply of spare parts and modules necessary for the repair and maintenance of data logging equipment acquired under the agreement.
The Environment Agency (EA) is transitioning to a unified Schneider-based national telemetry system, consolidating six legacy systems. Field equipment is managed and maintained by fourteen area-based operational teams, each responsible for ensuring reliable data collection and logging from environmental monitoring sites. Loggers with the option to meet some of the future telemetry requirements will also be considered as part of the framework.
As part of the telemetry system transition, the EA is adopting modern communication protocols including DNP3, WITS-DNP3, Lucid, and IP-based packet-switched data transmission. The technologies will support more robust and flexible data logging from field data loggers, enabling improved data integrity, accessibility, and analysis.
The new framework will comprise of two Lots, each with a set of functional requirements that must be met by the proposed data logger types. Where data loggers have telemetry functionality, they are required to operate with Schneider telemetry systems using either DNP3, WITS DNP3 or Lucid (when available) and inclusion of a multi band modem is desirable.
- Lot 1 - IP68 rated logger device to operate at level, flow and rainfall sites as backup devices to the main existing remote telemetry units. Maximum device dimensions of 170mm x 150mm x 80mm.
- Lot 2 - A single sensor IP68 rated logger device to operate where space may be limited. Dimensions should allow fitment within a tube diameter >50mm. Functionality to directly connect input sensors, without need for external junction box, to data logger whilst maintaining IP68 rating.
No information has been made available as yet with regard to the total estimated value of the framework.
Current estimated start and end contract dates are 12 January 2026 to 11 January 2029 with a possible further extension option to January 2031.
Engagement deadline is 28 November 2025 – DEFRA expects to issue a formal tender notice in early December
Interested suppliers will need to be registered with the Defra E- Commercial System on the Atamis Supplier Portal if they are not already on the system – visit https://defra-family.force.com/s/Welcome
