YW Business Risk
• Current asset would not achieve the P requirements.
• The works have reached the end of their asset life. The RBC requires maintenance, screens have been removed and the storm overflow
needs to be abandoned.
• Current discharge point is to a ‘grassed plot’

Chemical Dosing for P removal
• Conventional solution for 4mg/l TP consent is the provision of chemical dosing for P removal
• However, considerable supply chain issues surround projected Ferric Sulphate dosing requirements to meet future AMP7 TP consents
• These supply chain issues are further exacerbated by effects of Brexit and COVID 19 causing lorry driver shortages as recently reported by BBC

• Alternative nonchemical solutions for P removal are an attractive proposition and are being widely trialled by UK water companies in AMP7
• One such alternative is the use of land treatment solutions such as integrated constructed wetlands
