## Description
This notice is seeking expressions of interest for the establishment of a Contract for Continuous Water Quality Monitoring (CWQM) related to:
•	Site Planning & Investigation;
•	Hardware & Data Transmission; 
•	Installation, Maintenance & Calibration; and 
•	Data Visualisation & Analysis.
This Contract Agreement is envisaged to be the primary route for selecting supplier(s) for the delivery of the CWQM hardware and services for the duration of the Agreement.
Any estimated quantities or values contained or referred to in this or other documentation are for guidance only and do not bind YWS to buy any specific quantities should the bidder be successful and enter into an Agreement.
Yorkshire Water has a statutory obligation to deliver continuous water quality monitoring up and downstream of all discharges for parameters as outlined in the Interim Technical Standard of Section 82 of the Environmental Act 2021.
Interested bidders will have the opportunity to express interest to this tender and Yorkshire Water will reserve the right to either award everything to the lead supplier under a "Data as a Service" managed service model (Lot 1), or Asset Ownership model (Lot 2).
Lots 1 and 2 have the same service scope and requirements but under different commercial models. Interested bidders can provide submission(s) for Lots 1 and / or 2.
Bidders need to deliver all the required services of the Lots they intend to submit a response. Lots will be awarded at Yorkshire Water's discretion.
Procurement Process:
To express an interest in participating in the tender, please contact David Archer (David.Archer@yorkshirewater.co.uk) through email by 17:00 (GMT) on 9th October 2024.
Once a bidder expresses an interest, a Selection Question (SQ) document pack will be shared with them at a later date. This will include the SQ document that must be completed by all bidders and submitted in line with the deadlines included within the pack, which will be after the deadline to express an interest, giving bidders enough time to complete the documents.
All clarifications should be submitted on Ariba and can also be emailed to David Archer (David.Archer@yorkshirewater.co.uk) by 17:00 (GMT) on 27th September 2024.
YWS will periodically consolidate clarifications that would be relevant to everyone and share the response to these with all bidders anonymously.
Following an assessment of the SQ responses received, successful bidders will be invited to participate in the ITT. This is planned for November 2024 but is subject to changes based on YWS discretion.
