Representation

Thank for you the opportunity to comment on the Thurrock Flexible Energy project. Anglian Water is considered to be a statutory consultee for nationally significant infrastructure projects as identified in the Planning Act 2008 and associated regulations. The following representations are submitted on behalf of Anglian Water as sewerage undertaker for the above site: Anglian Water is in principle supportive of the above project. Impact on existing assets: There are existing sewers located within the boundary of the above project as shown on statutory asset plans. Draft DCO wording: Anglian Water is of the view that article 16 as drafted does not appear to be consistent. Paragraph (3) makes it clear that consent of the owner of the sewerage network is required to discharge water into it (subject to reasonableness); but paragraph (2) states that disputes must be determined in accordance with Section 106 of the Water Industry Act. However consent is not required as part of the Section 106 process nor can the capacity of the received network which is considered to be a planning issue be taken into account. We would therefore suggest at that article 16(2) (Discharge of Water) of the Draft DCO be replaced with the following wording: “(2) Any dispute arising from the making of connections to or the use of a public sewer or drain by the undertaker under paragraph (1) is to be determined in accordance with the arbitration provisions in article 43 (arbitration)” Protective provisions for Anglian Water: We have previously requested the inclusion of specific wording for the benefit of Anglian Water to ensure that we can continue to serve our customers and limit the potential for disruption to the services we provide to our customers. It is noted that specific protective provisions for Anglian Water are not included in the current version of the DCO. Therefore we recommend that the Draft DCO is amended to include specific protective provisions for Anglian Water as previously requested. Therefore we would wish to make a holding objection to Draft DCO wording for the reasons set out above. Connections to public sewerage networks: We note that an on-site package treatment plant or tankering off site is currently the preferred option for the discharge of foul flows from the welfare facilities which form part of proposed development (7.3 – Conceptual Drainage Strategy) with details to be developed and agreed post consent. Similarly it is proposed to develop attenuation basins and associated infrastructure to manage surface water which is expected to be discharged into ditches. As such the foul and surface water drainage strategy for the proposed development does not appear to interact with Anglian Water's operated assets. Therefore we would expect the Environment Agency and Thurrock Council as Lead Local Flood Authority to comment on the suitability of proposed method of foul and surface water drainage. In the event that the method of foul and surface water were to require a connection to the public sewerage network following approval we would wish to be consulted to ensure that any revised strategy is sustainable and that there is no detriment to our customers. Should you have any queries relating to this response please let me know.
