A sewerage undertaker whose area is wholly or mainly in England must publish annual reports in relation to the undertaker's storm overflows ("storm overflow reports").
A storm overflow report must specify, for each of the sewerage undertaker's storm overflows—
the location of the storm overflow;
the watercourse, body of water or underground strata into which the storm overflow discharges;
the frequency and duration of discharges from the storm overflow in the period to which the report relates;
where the information is available, the volume of each discharge in that period;
information on any investigations that have taken place or improvement works that have been undertaken in relation to the storm overflow during that period.
Storm overflow reports are to relate to successive calendar years, starting with 2021.
A storm overflow report must be published by a sewerage undertaker before 1 April in the year after the calendar year to which it relates.
A storm overflow report must—
be in a form which allows the public readily to understand the information contained in the report, and
be published in a way which makes the report readily accessible to the public.
The duties of a sewerage undertaker under this section are enforceable under section 18 by—
the Secretary of State, or
the Authority, with the consent of or in accordance with a general authorisation given by the Secretary of State.
