DŵrCymru Welsh Water target energy savings in water supply

DŵrCymru Welsh Water have commissioned Tynemarch Systems to undertake a 6 month pilot  of the MISER real-time,sub-daily pump and valve scheduling software, to identify the electricity and other operating cost savings that can be achieved, whilst maintaining security of supply.

The initial implementation of the system will be used to provide pump schedules and monitor the performance of the Heads of the Valley area comprising some eight reservoirs and five sources.

MISER will take live information such as flows and reservoir levels from the telemetry system to forecast demand over the following few days. It will then produce pump and valve control settings automatically to manage the water supply network night and day to meet customer demands, licences and other constraints at minimum cost.

A key benefit is that MISER provides an holistic view of network operation and helps to control the flows through water treatment works, such as maintaining a steady flow where treatment is sensitive to flow fluctuations.

The system will also support in responding to routine maintenance and unplanned network events, to prevent or minimise any impact on customers. MISER can be used to provide operators with the most cost-effective strategy to recover from unplanned outages arising from equipment failure or pollution incidents for example.

The system can also optimise the operating costs of both medium-term operation (monthly) and long-term (yearly) resource utilisation (production planning) as well as short-term sub-daily pump and valve control.

Tynemarch will be providing support and maintenance for the system which will be operated from the DŵrCymru Welsh Water control room.

DwrCymruWelsh Water personnel will be trained to enable them to extend the MISER models to cover the remaining areas of the water supply system.
