The Barking Barrage Order 1995

Monitoring of chalk aquifer water pressure levels

66.—(1) Prior to the commencement of the scheduled works, the Borough shall ask Thames Water to propose relevant observation boreholes and, upon agreement by the Borough (which may include adding to or varying the list), Thames Water may require the Borough to implement a detailed programme for the monitoring of chalk aquifer water pressure levels in the vicinity of the river, which shall include—

(a) detailed monitoring by the Borough during the time of construction of the barrage and for a period of not longer than one year after practical completion of construction of the barrage;

(b) access arrangements to the relevant observation boreholes to be made by Thames Water to enable the Borough to undertake the work;

(c) the necessary computer facilities and programmes to be provided by the Borough with advice and assistance of Thames Water; and

(d) arrangements for the Borough to circulate to Thames Water the results of monitoring.

• Provided that the Borough shall be consulted on the terms of the monitoring programme and shall comment thereon within 28 days of receiving a draft programme and Thames Water shall consider the Borough’s comments before implementation of the programme.

(2) Should the results of monitoring indicate that, on account of the existence or operation of the barrage, there is an effect on the said chalk aquifer which is likely to be detrimental to the future operation of the public supply source abstracting ground water at East Ham pumping station at reference point TQ43748424, the Borough shall take steps as may be necessary to rectify the situation or compensate Thames Water for the loss of this source.
