Eleven pupils from the school have been involved in the joint art project with the support of East Renfrewshire Culture and Leisure and the council.
The mosaic is now on display at the site, which has been completely transformed into a community-friendly space.
Arts Development Officer Tess Forbes, from East Renfrewshire Culture and Leisure, explained: “We were delighted when St Ninian’s approached us to work on a creative project. The pupils went through the process of creating a concept for the regeneration of the Waterworks site and what they felt the community would benefit from. We then invited them to create a permanent feature.
“They came up with the idea of a mosaic and designed the motif themselves. The pupils then created the mosaic depicting a flower inspired by how green the Water Works is, the wild flower garden and the orchard.
“They have also included their initials on the design.”
The pupils studied Public Art with teacher Katie Joice, who conducted visits to the site over the course of the project and undertook research to understand how the public interact with the area and what the Waterworks would benefits from, before agreeing on their final design.
St. Ninian’s Art and Design teacher Katie Joice said: “We are proud to see the pupils’ artwork displayed prominently at Barrhead Waterworks. As well as being a great achievement for the pupils, the mosaic really brings the space to life for the community.”
