6. Supplier Market Engagement Events

Scottish Water intends to host one or more market engagement events during October 2026 to meet with organisations that can provide all or part of the services outlined within this PIN. The anticipated date of the market day is 8 October 2026; however, this is subject to change and will be confirmed closer to the time.

The purpose of these sessions is to better understand current market capabilities, supplier experience, delivery models, innovative approaches including digital leakage solutions, emerging technologies, and opportunities to help shape Scottish Water's future leakage strategy and procurement approach. Scottish Water is seeking insight into the range of client and supply chain operating models that can incentivise and drive significant improvements in leakage performance, including integrated, enterprise style approaches that move beyond the traditional client contractor model.

Scottish Water welcomes participation from suppliers and is keen to engage with organisations that can offer specialist services, integrated end to end solutions, or innovative approaches to leakage detection, monitoring, analytics, customer side leakage management, repair activities, network conditioning and flushing services.

Suppliers interested in participating in these market engagement events should submit the information requested in Section 5 and register their interest by contacting [email protected] no later than 12:00pm on 25 September 2026. Further details regarding the format, location and timing of the events will be provided to relevant interested parties.

Scottish Water will manage this process in an open and transparent manner to maximise the potential benefits. Participation or non participation in informal discussions or the Market Day will neither preclude participation in, nor provide any advantage or disadvantage to, suppliers in any subsequent procurement process.

Scottish Water shall have no liability for any costs incurred by organisations attending the Market Day or otherwise participating in this engagement activity.

Direct or indirect canvassing of any Scottish Water representative concerning this procurement, or any attempt to obtain information relating to this Prior Information Notice outside of the formal process described in this document, may result in disqualification from this procurement and may be taken into consideration in future procurement activities.
