Reservoirs Act 1975

Monitoring and supervision

11Recording of water levels etc.

(1)For every large raised reservoir the undertakers shall keep a record in the prescribed form of—

(a)water levels and depth of water, including the flow of water over the waste weir or overflow ;

(b)leakages, settlements of walls or other works, and repairs;

(c)such other matters as may be prescribed ;

and shall install and maintain such instruments as may be needed to provide the information to be recorded.

(2)The record to be kept for a reservoir under this section shall give such information as may be prescribed of any of the matters to be included in the record, and shall give it at such intervals and in such manner as may from time to time be required by any directions of the construction engineer or inspecting engineer.

12Supervision of large raised reservoirs

(1)At all times when a large raised reservoir is not under the supervision of a construction engineer, a qualified civil engineer (" the supervising engineer ") shall be employed to supervise the reservoir and keep the undertakers advised of its behaviour in any respect that might affect safety, and to watch that the provisions of section 6(2) to (4) or section 9(2) above and of section 11 are observed and complied with and draw the attention of the undertakers to any breach of those provisions.

(2)It shall be the duty of the supervising engineer, so long as any matters are noted as matters that need to be watched by him in any annex to the final certificate for the reservoir or in the latest report of an inspecting engineer, to pay attention in particular to those matters and to give the undertakers not less often than once a year a written statement of the action he has taken to do so.

(3)The supervising engineer shall recommend to the undertakers that the reservoir be inspected under section 10 above, if at any time he thinks that such an inspection is called for.

(4)Where it appears to the enforcement authority that a large raised reservoir is not for the time being under the supervision either of a construction engineer or of a supervising engineer, the authority may by written notice served on the undertakers require them within twenty-eight days after the date the notice is served to appoint a supervising engineer and to notify the authority of the appointment or, if the reservoir is at that date under the supervision of a construction engineer or of a supervising engineer, to notify the authority of that fact.

(5)References in this section to a construction engineer include an engineer acting under section 8 or 9 above.
