Title: An investigation into the effect of Farnham STW on the River Wey
Author: Mark Liddiard
Document Type: Monograph
This study was carried out to determine the effect of the effluent from Farnham STW on the water quality in the north arm of the River Wey. The effluent quality was examined for compliance to the discharge consent. The quality of the water found in the river, both upstream and downstram of the effluent discharge, was studied to see if it complied with current R.Q.O. standards. The current RQO's were also examined to determine if they were appropriate for the uses of the river and to see if they should be changed at all to reflect water quality on river usage. The River Wey's North arm rises in the Alton area and flows north-east through largely agricultural land. The main sewage treatment works upstream are at Alton and Bentley which are both a considerable distance away and should have no effect on the water quality at Farnham. The only major tributary is the Caker Stream which is right at the head of the catchment and there are no other major discharges into the river. The aim of this study is to assess whether these RQO's are appropriate given the quality of the water in the Wey North and the effluent produced by Farnham STW.
