CONSTRUCTED WETLAND ASSOCIATION ANNUAL CONFERENCE: ‘How to make better constructed wetlands’ 12 & 13 September 2018, University of Portsmouth, UK

The 14th Annual Conference ‘How to make better constructed wetlands’ is taking place on the 12th & 13th September at Portsmouth University, recognised for its long history of wetland research. DAY ONE (12th SEPTEMBER): TRAINING MORNING

This interactive training workshop, in partnership with CIWEM, will introduce constructed wetland technologies and their application to domestic, industrial and agricultural wastewater treatment. Wetland experts will present the latest technologies and

approaches to point source and diffuse discharges to deliver catchment water quality improvements and, through a series of case studies, discuss ongoing management and maintenance requirements and the wider benefits, in addition to water treatment, that can be delivered by constructed wetlands. Workshops:- • Introduction to constructed wetlands - Dr Matthew Simpson, Associate Director, WWT

Consulting • Design, operation and maintenance impacts on treatment wetlands’ performance – Dr Gabriela

Dotro, Senior Research Fellow, Cranfield University • Applications of constructed wetlands – Geoff Sweaney, Director, Wetland Engineering Ltd. DAY ONE (12th SEPTEMBER): AFTERNOON SITE VISIT On the afternoon of 12th September, delegates will visit two sites near to Portsmouth. SITE 1: Berewood Major Development Area Sustainable Drainage

Berewood is a new-build township of 2550 units, approximately 12km north of Portsmouth. The site is in the catchment of the River Wallington, which has a history of flooding Wallington Village downstream. Sustainable Drainage Schemes (SuDS) have been integral to the design in order to mitigate flood risk and enhance water quality.

The SuDS features include a treatment train of enhanced swales, linear detention basins, ponds and wetlands, with areas of porous paving, underground storage tanks and vortex separators. There is also a river restoration programme for a highly modified tributary of the River Wallington. Various green corridors and wildlife areas have been included in the master plan to enhance biodiversity in the development. The effect of the SuDS have been studied by Portsmouth University in collaboration with the SuDS designer Mayer Brown Ltd and are included in the Wildfowl and Wetlands Trust’s Working Wetlands directory. SITE 2: University of Portsmouth Environmental Technology Field Station

This field station is at a Southern Water operational wastewater treatment works at Petersfield, approximately 20 miles north of Portsmouth. It is a conventional trickling filter works with an ARM Forced Bed Aeration Constructed Wetland for tertiary treatment. The site visit will involve a tour of the sewage works and the University facilities.

The University has onsite laboratories and a greenhouse. It hosts a collaborative Innovation Hub between the University and Southern Water as well as other projects. This site has hosted many studies of constructed wetlands for a range of applications. Ongoing activities of interest to the CWA include: - Simulation of pollutant transport in swales in a 10m greenhouse swale - Field scale studies of reactive media for phosphorus removal that will be scaled up to a full scale site study at a local site later in the year. DAY ONE (12th September): CWA AGM & EVENING SOCIAL All delegates are invited to attend the CWA Annual Meeting on the afternoon of day 1, where they can have their say in the CWA’s direction, strategy and committee for 2018/19. This will be followed by a social evening on 12th September at the local Still & West pub. DAY TWO (13th September): PRESENTATIONS Day two (13th September) will bring delegates up to date with the latest developments in constructed wetlands through presentations sharing the knowledge of leading academics and practitioners in the field of constructed wetlands with the key themes: • Building partnerships to deliver multiple wetland benefits • Using natural ecosystems to reduce pollution in river catchments • New approaches to wetland design CONFERENCE SESSIONS AND SPEAKERS:- • KEYNOTE: The historical development of constructed wetlands for wastewater

ENTER OUR POSTER COMPETITION! We are inviting students, practitioners and academics specialising in constructed wetlands to produce and submit a relevant, creative and interesting poster for display at the Annual Conference. Posters can illustrate recent wetland research or showcase an innovative project, ideally relating to one of the main event themes: • Building partnerships to deliver multiple wetland benefits • Using natural ecosystems to reduce pollution in river catchments • New approaches to wetland design A short overview summarising your research / case study and its findings of no more than 150 words should be submitted using our website or by sending us an email by 1st September 2018. Whilst entries from all types of researchers and practitioners are welcome, there will be separate, cash prize for the best student poster. Attendees at the event will vote for the posters that have impressed them the most. This is a great opportunity for to showcase innovation and enable the next generation of wetlands experts to display their latest research findings to a wide range of stakeholders in the wetland community.
