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

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.

Leakage detection and location equipment or devices that are used to measure and direct active leakage reduction activities.

Leakage localisation devices (units): which identify and prioritise the areas and points of interest of leakage to make the pinpointing of leaks easier.

Leakage pinpointing methods: which identify the position points of interest including leaks as accurately as possible.

Data acquisition: equipment or devices that gather and store measured data or signals. Data acquisition equipment may include computers, data loggers, network ancillaries, remote terminal units, highspeed timers, random access memory (RAM) devices and USB flash drives.

Data processing software: All data processing required to pinpoint the location of the potential point of interest and or leak is to be provided. All raw and processed data is to be made available for access and transfer to SWS.

Output displays: Hand-held or on-line displays which are to be used during leak detection operation on site (localisation and pinpointing) with an option for future integration/data transfer into SWS event management platforms.

Services: Services associated with recycling and disposal of equipment.

Pressure Controller equipment or devices that are used to control Pressure such as Pressure Reduction Valves (PRV’s), Enabling SWS to monitor live data enabling the use of network operating systems to carry out Calm network operations.

Data acquisition: Controllers should be logging at a minimum of 1min cycles and be set to transmit this data back to the main server at 15 minute intervals.

The interval and cycles should be able to be changed remotely to near real time data with this information being available for incident control.

Data processing software: All raw and / or processed data is to be made available for access and transfer to SW Waternet system.

Output displays: Hand-held or on-line displays with full integration into SWS event management platforms.

IP68

Monitors, cabling and connections / ancillaries will be IP68 rated to prevent the ingress of dirt particles and liquid into the equipment.

Southern Water Services (SWS) have procured pressure transient loggers previously and SWS now wishes to procure additional pressure transient devices that are used to monitor pressure transient waves within a water network which are believed to cause bursts and leakage, making them a key part of SWS’s leakage control effort.

Pressure Transient devices (units): which identify and triangulate the source of pressure transients waves.

Data acquisition: Pressure is to be measured at a frequency of at least 60 samples per second (60Hz) as well as providing summarised data as average, minimum, and maximum pressures in 1-minute intervals (or as required by SWS). Internal clocks are to be aligned to sub-second accuracy.

Data processing software: Sufficient software to convert the raw pressure measurements into events based on pre-defined criteria (magnitude, duration, frequency) and provision of summaries (average, minimum, maximum for 1-minute intervals).

Output displays: The Web Hosted Platform can be accessed as a web page with an option for further integration/data transfer into SWS event management platforms in the future.

Services: Analytical support for interpretation of the logger results and logger management and deployment if required.

Support during installation and setting up: Advice and recommendations for best positioning and setting up of the units.

IP68: Monitors, cabling and connections / ancillaries will be IP68 rated to prevent the ingress of dirt particles and liquid into the equipment.

Pre-assembled system shall be provided ready to be used by SWS Framework contractors.
