Our Story

Welsh Water took over Lisvane & Llanishen Reservoirs in 2016 and became guardians of its amazing ecology and heritage.

Built in the late-19th century, this Victorian landmark covers 110 acres of green and blue space and is home to amazing flora and fauna – offering an oasis of calm just a few miles from Cardiff’s city centre.

Lisvane Reservoir is designated a Site of Special Scientific Interest (SSSI) for overwintering birds and the embankments of both reservoirs are designated SSSI for waxcap fungi. Much of the reservoir grassland and scrub woodland outside the SSSI is designated as a Site of Importance for Nature Conservation (SINC).

Whilst understanding its ecological importance, we have recognised the site’s potential as a hub for recreation, health and wellbeing. We have strived to open up an area in our vibrant capital where people can reconnect with water and our beautiful environment. Our aim has been to maximise public access whilst protecting and enhancing the ecology of the site.

The redevelopment of the site has been carried out in consultation with stakeholders and using feedback received from the local community.

Not For Profit

Dwr Cymru Welsh Water is a not-for-profit water company. We don’t have shareholders, which means that we put every single penny we make straight back into keeping bills down and looking after your water and beautiful environment – now, and for years to come.

We think it’s a much better way of doing things.
