Description

Morgan Sindall working with Dŵr Cymru Welsh Water, successfully implemented a catchment approach to phosphorus removal in the River Wye Catchment; with over of 16 kg/day (4.8tonnes/year) of additional Phosphorus removed from the river.

The schemes included a variety of solutions tailored to meet each WwTW specific requirements:

• Hereford WwTW
- Installation of a Bluewater Bio FilterClear Multi-Media filtration system at Rotherwas WwTW.
- Chemical dosing system upgrade at Eign WwTW.
- Implementation of a combined Total P load discharge limit from Eign and Rotherwas WwTWs.

• Leominster WwTW
- Installation of a Brightwork Nitrifying Continuous Sand Filter ensuring tightened Total P and Ammonia permits limits are complied with.

• Presteigne WwTW, Pontrilas WwTW, Clyro WwTW and Weobley WwTW
- Installation of chemical dosing systems to meet new Total P permit limits.

• Kingstone and Madley WwTW
- Installation of chemical dosing systems to meet a new Total P permit limit.
- Refurbishment of existing aerated reedbed and installation of additional aerated reedbed.

This paper presents how Morgan Sindall successfully managed the design and delivery of solutions on time and under budget for DCWW across the River Wye Catchment to meet DCWW regulatory obligations and improving service and the environment for its customers.
