A country public house in the North of England case study

A Public House had a new treatment plant installed in order to comply with the new discharge consent levels for BOD imposed by the River Authorities.

A few months after the plant was commissioned the National Rivers Authority took samples and reported that the discharge was far above the BOD consent level by a factor of ten. The contractors were contacted and they recommended that wastes such as cream, fat and beer pipeline cleaning fluid should not be permitted to enter the sewage treatment plant as well as recommending de-sludging the plant at more frequent intervals.

Despite these actions the BOD level however remained substantially above consent and some months later the tenants received a Summons issued by the National Rivers Authority for contravention of the discharge consent conditions.

An independent report was commissioned. This indicated that the plant was probably incapable of meeting the consent levels in its present form. It appeared at that stage that the sewage treatment plant would have to be replaced at substantial cost

A month before the date of the hearing of the Summons instructions were issued to Cleveland Biotech Limited to investigate the sewage disposal unit at the public house with a view to bringing the effluent discharge within the consent levels. A report was provided which recommended modifications costing less than £200 and the introduction into the system of bacteria to degrade the waste matter. The tenants approved the proposal to bio-augment the plant with Amnite L100 and within two weeks of starting the programme the plant was operating within consent.

When the case against the tenants was heard the tenants received an absolute discharge on all counts with no order for costs.
