New plans for Llanishen and Lisvane reservoirs have been announced

Welsh Water has unveiled plans for Llanishen and Lisvane reservoirs for the first time – including a brand-new visitor centre and exciting plans for facilities.

They took over Lisvane and 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).

Since taking over Lisvane and Llanishen reservoirs in 2016 they have been working to bring them back to their former glory. Whilst understanding the ecological importance of the site, they also recognise the site’s potential to create a  hub for recreation, health and wellbeing – and provide an area in our vibrant capital where people can reconnect with water and our beautiful environment. Our proposals aim to maximise public access whilst protecting and enhancing the ecology of the site. They have been developed in consultation with key stakeholders and using feedback received from the local community.


As part of their plans to transform the reservoirs into a hub for health and wellbeing, they intend to bring back watersports to Lisvane and Llanishen reservoirs, plans include providing water-based activities – windsurfing, stand-up paddleboarding, canoeing, kayaking, electric picnic boats, and more.

Sailing would also come back to Lisvane and Llanishen reservoirs for the first time since the club was moved to Cardiff Bay in 2010. The site was one of the most prominent and well-loved sailing training centres in Wales and our intention will be to bring back this sport for people in Cardiff and South Wales to enjoy once more.

They also intend to bring paddleboarding, canoeing and kayaking to the reservoir – allowing everyone the chance to enjoy a range of watersports and learn new skills in a safe inland environment.

More details on the new develop[ments of the site can be found on the Welsh water website  – Welsh water Lisvane Reservoir
