The Use of Mathematical Modelling to Demonstrate Effective Environmental Solutions to Intermittent Discharge Problems in North West UK
Publication: Urban Drainage Modeling
Abstract
As a result of the agreed Asset Management Plan for North West Water (NWW) covering the period from April 2000 to March 2005 (AMP3), there is a need to improve a total of 919 unsatisfactory intermittent discharges to surface waters, either at Wastewater Treatment Works (storm tanks or inlet CSOs) or within the wastewater network. The 919 intermittent discharges are made up as follows: 1) 125 are designated as impacting on bathing Water / shellfish waters, 2) 353 are designated as having an aesthetic impact without river impact, and 3) 441 are designated as having an impact on the in-river quality. (River Impact). Some linking of problems has been carried out to ensure that geographical location is taken into account. From this the following numbers have been identified: 1) 585 river impact and linked aesthetics / bathing waters, 2) 121 stand alone bathing water / shellfish intermittents, and 3) 213 stand alone aesthetic intermittents. The three categories have differing modelling study requirements, as the design standards are different.
