This event is aimed at CIWEM members interested in understanding what is required to upgrade a working treatment plant so that it complies with new tighter permits. Construction work presently underway presents an ideal opportunity for members to look at the design engineering and construction methods necessary to install new process units and upgrade of assets within an existing wastewater treatment plant.
Yeovil (Pen Mill) WRC is owned and operated by Wessex Water and serves the Somerset town of Yeovil and catchment with a Population Equivalent (PE) of 75,000. Its existing permit requires treatment of flows up to 397litres/second.
The tour will be given by Wessex Water Project Delivery staff (led by Stuart Pile) and is intended to present the process improvements presently underway as part of a major AMP7 upgrade of the plant.
Members will be given a tour of the site with an opportunity to see the construction works taking place. This includes new Primary Settlement Tanks, High Rate Filter and package TSR plants designed specifically to remove ammonia and phosphorus (these utilising MBBR and MMF treatment technology).
The tour is intended to showcase the size and scale of construction required to treat dry weather flows up to 400l/s and some of the new treatment processes being installed by Wessex Water to reduce nutrient levels to below permit thresholds.
As this visit is on a construction site, it is important for those attending to wear the appropriate PPE, including long sleeved Hi-Viz vest or jacket, steel toed boots, hard hat and cut 5 level gloves.
We will meet at 9:45am for a 10:00 am start.
Part of the CIWEM Wastewater and Biosolids series.
Stuart Pile is a design co-ordination engineer at Wessex Water. He has been working within the water industry for 15 years (both overseas and within the UK) and is a Chartered Member of CIWEM. Stuart joined Wessex Water in 2020 and was been heavily involved in the design of the AMP7 upgrade for the Yeovil Pen Mill WRC. This involved extensive liaison with design consultants throughout a two and half year design programme as well as the interface management of numerous external suppliers of proprietary treatment technology installed as part of the upgrade.
Paul Duffy is principal mechanical engineer at AECOM and has over 20 years in the water industry as a consultant in field. He is an Associate Member of iChemE and has an extensive track record in the design of treatment and network solutions in both clean and waste water environments. Paul lead the AECOM team in the mechanical design of the plant upgrade at Yeovil Pen Mill ensuring that all new proprietary treatment processes were dovetailed into the existing process flow.
The engineering design for the AMP7 upgrade at the Yeovil Pen Mill WRC is widely regarded as one of the most successful achievements of Wessex Water’s capital upgrade programme for the period 2020-25.
This event is open to members and non-members of CIWEM.

The event will take place at the Wessex Water Yeovil Pen Mill Water Recycling Centre, Flushing Meadow (off Sherborne Road), Yeovil, BA21 5BG. The venue is only five minutes’ walk from the Yeovil Pen Mill train station. This provides a realistic opportunity to reach the event via public transport.
The site is an active construction site and therefore requires a high level of mandatory PPE. This as follows:
Long sleeved Hi-Viz vest or jacket, steel toed boots, hard hat and cut 5 level gloves must be worn when on site.
Travelling to the venue
As part of CIWEM’s commitment to tackling the climate and ecological emergency we would encourage delegates to use the most environmentally sustainable means of transport possible.
By Train | Underground | Tram
Yeovil Pen Mill railway station is the nearest mainline railway station to Yeovil Pen Mill WRC and is also off Sherborne Road - short walk from the treatment plant. Yeovil Pen Mill train station is served by GWR has direct services from Bath and Bristol.
Yeovil Junction train station is served by trains from Exeter. This train station is further afield so you would either need to change trains to get to Yeovil Pen Mill or book a taxi to take you to the treatment plant.
By Bus | Coach
The no 58/58A bus from Wincanton stop at Yeovil Pen Mill approach.
By foot | cycle
The Yeovil Pen Mill WRC is only five minutes’ walk from Yeovil Pen Mill railway station and twenty minutes from Yeovil bus station respectively.
If you are coming by car, please consider sharing the journey with others to reduce your environmental footprint.
Visitor parking is presently provided for through a lease agreement Wessex Water have with a neighbouring business within the Yeovil Pen Mill Industrial area – namely Pittards. Please follow the signs when parking here before then signing in at the temporary security arrangement presently in place.
Guests should then follow the pedestrian signs to Gate B before following the pedestrian signs to the welcome cabins and the site office where they will be greeted by Wessex Water staff.
As this is an in-person event, please remain vigilant to control the spread of COVID-19 and stay safe.
We would request that if you think you might have contracted COVID or have recently had the disease, that you do not attend the workshop.
