Dŵr Cymru Cyfyngedig (DCC) Welsh Water has launched a market engagement exercise to assess filtration options for network cleaning, ahead of initiating a tender process to secure delivery of bag filters for network cleaning from 2025 for a potential period of up to 8 years.

As part of continuous improvement activities to drinking water treatment and quality, the water company has identified the need for alternative water network cleaning technologies to remove any accumulation of sediment. To fulfil this requirement Welsh Water is looking for bag filters which can be integrated with a mobile water network cleaning technology.
The utility is reviewing a multitude of filter options – as part of this it requires filters which produce less of an impact during maintenance and filters that are DWI regulation 31 approved. The filters will be integrated with a mobile water network cleaning technology which circulates and filters water for general water quality improvements.
The constituent elements of the service are as follows:
- Improvements to the quality and the reliability of drinking water supply
- Increased efficiency by responding rapidly to deteriorating water quality
- Increased visibility of a market and collaboration with providers
- Increase resilience and competition from filter manufacturers
Welsh Water has now issued a Periodic Indicative Notice(PIN) to launch a market engagement exercise before publishing a formal contract notice - currently expected to be in late Spring/early Summer 2024.
The primary focus of the market engagement is to gain market intelligence and an insight into market availability, to test with the market various options for delivery that will offer the greatest value for customers, as well as any perceived risks and opportunities.
Key requirements outlined in the PIN are:
- A set of filters that comply with DWI regulation 31 and are capable of integrating with a vessel holding between 7-12 bag filters. DWI regulation 31 approval for the product must be sustained throughout the duration of the agreement or already be held.
- A filter vessel that comply with DWI regulation 31 that is capable of holding between 7-12 bag filters.
Welsh Water will provide further details on this opportunity, together with a short questionnaire to companies responding to the PIN. The water company envisages holding a series of one-to-one meetings in July 2024- September 2024 to further discuss the content of the completed questionnaire.
The utility is inviting suppliers with experience of any of the goods described in the PIN to participate in the market engagement process by registering their interest by 10th July 2024 and responding to the questionnaire by 17th July 2024.
