                          Northumbrian Water Group plc


                                (the "Company")


                          Dealings by employee trusts


The Company has been informed that Northumbrian Water Share Scheme Trustees
Limited (the Trustee of the NWG Long Term Incentive Plan) has today, 12 February
2007, sold 6,560 ordinary 10 pence shares as a result of the exercise of an LTIP
award by someone who is neither a director of the Company nor a person
discharging managerial responsibility ("PDMR"). The sale of these shares is
pursuant to a conditional award of shares made on 27 January 2004.


Following this reduction, the Trustee holds 804,428 shares, representing 0.155%
of the Company's issued share capital.


The Trustee holds these shares in order to satisfy awards made under the
Company's LTIP, and so John Cuthbert and Chris Green, as executive directors of
the Company, and Ceri Jones and Graham Neave, as PDMRs of the Company, are
potential beneficiaries of these shares.



In addition, the Company was advised on 12 February 2007 by the Trustee of the
Northumbrian Water Group plc Share Incentive Plan (the "SIP Trustee") that on 9
February 2007 it released 3,120 ordinary 10 pence shares on behalf of certain
participants of the Company's Share Incentive Plan who have left the Company.


Following this transaction the SIP Trustee holds a total of 1,719,153 shares
representing 0.33% of the share capital of the Company.


The following people John Cuthbert (Director), Chris Green (Director) and Ceri
Jones (PDMR) are beneficiaries along with other employees, and as such, each is
deemed to be interested in the shares held by the SIP Trustee.


This announcement is made in accordance with the requirements of DTR 3.1.4 R(1).
