Title: An investigation into the water quality of a treated effluent from Hambleton Dairy, Todber, Dorset
Author: Jenny Watkinson
Document Type: Monograph
Hambledon Dairy is situated at Todber, Sturminster Newton, Dorset. The dairy has a consent to discharge treated sewage effluent, milk parlour washings and waste from the pasteurisation unit via the treatment plant installed at the site. The final effluent is discharged to a lagoon which connects via a series of drainage ditches to the Key Brook, a tributary of the River Stour. Routine Audit of the effluent and additional monitoring by Water Quality highlighted persistent consent failures from the treatment plant installed at the site. The dairy runs at peak output from 0600 to 1200 and off-peak output from 1200 to 0600, Monday to Friday and shuts down completely over the weekend. It was suspected that the effluent quality may vary over time due to the variety of dairy processes and the intermittent use of cleaning chemicals which include Hydrogen Peroxide, Phosphoric acid and Hypochlorite.
