Summary of the contracting process

Southern Water Services Limited procured telemetry equipment for its water and wastewater operations in Kent, Sussex, Hampshire and the Isle of Wight. The requirement covers remote outstations and field devices that transmit operational data and alarms to area or regional control centres, with remote monitoring, control and diagnostics for isolated and unmanned sites. Three active lots cover mains-powered large outstations, mains-powered small outstations and battery-powered outstations. The equipment supports electro-mechanical assets such as pumps, and may also serve reservoirs, sewers and outfalls. Spares are included, together with ancillary software development and integration, warranties, installation, commissioning and training. The procurement category is telemetry equipment (CPV 32441000).

The procurement has been awarded through a selective negotiated procedure with prior competition, using a framework agreement and successive reduction. The tender submission deadline was 30 April 2024 at 17:00. The original estimated value was £8.8 million. The active lots were estimated at £1.2 million for large mains outstations, £800,000 for small mains outstations and £600,000 for battery outstations. Contracts were signed with Schneider Electric Systems UK Limited for £1,900,548.54 on 6 July 2026, Ovarro LD Ltd for £1,900,548.54 and £549,728.59 on 11 September 2026, and HWM-Water Limited for £39,849.04 on 20 July 2026. The framework duration is 1,440 days, with an option to extend by up to four years. Evaluation used technical quality and price, generally weighted 60% and 40%.

This award demonstrates recurring demand from Southern Water for telemetry suppliers able to support operational water and wastewater assets at scale. Credible competitors would need to manufacture or supply robust remote outstations in mains-powered large, mains-powered small and battery configurations, with reliable transmission of data and alarms from isolated sites. Relevant capability includes remote monitoring, control and diagnostics, battery back-up, spare-parts support and integration with operational control or event-management systems. Suppliers offering software development, installation, commissioning, warranties and training would match the wider requirement. The successful supplier group included both SMEs and larger businesses, indicating that specialist telemetry manufacturers and established control-system providers can compete. Businesses should be able to demonstrate technical quality alongside competitive pricing, and deliver equipment suitable for pumps, reservoirs, sewers and outfalls across Southern Water’s operating area.

Notice Information

Notice Title

prj_6010 - Telemetry Framework Lots 5a, 5b and 5c

Notice Description

Telemetry shall provide a means of transmitting key data and alarms between the site and an area or regional control centre. All operational sites that include electro-mechanical assets shall be provided with Telemetry monitoring. In some instances, telemetry may also be used to remotely control assets - typically pumps in the water supply process. Other sites or locations that do not include electro-mechanical assets may also have a requirement for telemetry where specified by the Purchaser - this includes such assets as reservoirs, sewers and outfalls. Southern Water Services (SWS) is looking to procure remote telemetry units. That is, an outstation / field device that provides remote monitoring, control and diagnostic facilities for isolated and unmanned sites.

Lot Information

Lot 1 - Pressure & Flow Loggers

Southern Water Services (SWS) wishes to procure flow and pressure logging equipment or devices that are used to measure flow and pressure within the potable water network, enabling SWS to monitor live data enabling the use of network operating systems to carry out Calm network operations. Flow devices - Pre-Calibrated, and able to accurately measure flow within the network giving real time l/s performance of the network. Flow devices where possible should record the following: - Flow measurement - Temperature measurement - Pressure measurement - Analytical measurement - Level measurement - Battery Usage / % left - GSM/GPRS/NBIoT Signal Strength Pressure Logging devices - Pre-Calibrated, and able to accurately measure pressure within the network giving real time m/h performance of the network. The simplest loggers record one channel of pressure data and are suitable for locations such as the AZP (Average Zonal Point) or CPP (Critical Pressure Point), however pressure loggers with greater than one channel recording are required. Pressure devices where possible should record the following: - Pressure measurement - Temperature measurement - Analytical measurement - Battery Usage / % left - GSM/GPRS/NBIoT Signal Strength Data acquisition: 1. Flow devices should be logging at a minimum of 15min cycles and be set to transmit this data back to the main server at 15minute intervals. 2. Pressure devices should be logging at 1min cycles and be set to transmit this data back to the main server at 15minute cycles. Data availability and storage costs need to be made available before any procurement is carried out to ensure the most cost effect solution for need is selected. The interval and cycles should be able to be changed remotely to near real time data with this information being available for incident control.

Renewal: ICA Telemetry framework agreement lasting 4 years, with an option to extend for a period of up to 4 years.
