NOTICE OF PROPOSAL TO CONFIRM A PROVISIONAL ORDER
Anglian Water Services Limited
Notice under section 20 of the Water Industry Act 1991 (as amended)
The Secretary of State for Environment, Food and Rural Affairs gives notice as required by section 20(1) of the Water Industry Act 1991 that –
- he proposes to confirm the Provisional Enforcement Order dated (19 January 2026) (“the Order”) made under section 18 of the Water Industry Act 1991 (‘the Act’) prohibiting Anglian Water Services Ltd (‘the company’) from supplying water for the purposes of regulation 4(1) of the Water Supply (Water Quality) Regulations 2016 (‘the Regulations’) from the Lincoln to Grantham (L2G) section of the Strategic Pipeline Alliance (SPA) Main;
- the purpose of confirming the Order would be to secure compliance with regulation 31(1) of the Regulations;
- the Drinking Water Inspectorate (‘the Inspectorate’) were informed of the inappropriate use of Acothane DW (DWI approval reference 56/4/1059) to repair sections of the L2G, SPA Main, constructed of Noksel Steel Water Pipe (DWI approval reference 56/4/1192). Whilst both products hold approval under Regulation 31(4)(a), all use of such products must be in accordance with the conditions of approval. The products have not been approved to be used in conjunction, in this manner. The company was issued with testing to confirm compliance with regulation 31(1) of the Regulations in relation to the materials in contact with drinking water within the L2G section of the SPA Main;
- the company has not completed the required testing and is therefore unable to evidence compliance with regulation 31(1). The Secretary of State does not consider that the exemption at regulation 31(2) applies);
- he considers that confirmation of the Order is justified as the inappropriate and unapproved use of materials in contact with water intended for human consumption, as detailed in the Order, could pose an immediate risk to human health;
- in the event that the Order is confirmed its effect is to place the company under a statutory obligation to comply with the steps and reporting required under the schedule of works associated with the Order. The obligation to comply with an enforcement order is a duty owed to any person who may be affected by a contravention of the order (section 22(1) of the Act). Please note that any breach of this duty may render the company actionable for any loss or damage caused by non-compliance by a person affected, subject to the statutory defence under section 22(3) of the Act. Failure to comply may also result in civil proceedings being brought against the company by the Chief Inspector in respect of any contravention or apprehended contravention for an injunction or for any other appropriate relief (section 22(4) of the Act).
- representations or objections with respect to the confirmation of the Order may be made by 5:00pm on 16 February 2026 and should be addressed to Marcus Rink, Chief Inspector of Drinking Water at DWI.Enforcement@defra.gov.uk.
