Greener Grangetown starts at last

21 November 2016

Work on a new water recycling project, which will see new green spaces and tree-planting in a dozen streets, has got under way.

There was a packed meeting of residents involved in Greener Grangetown at a “meet the contractors” event at Grangetown Hub on Tuesday 15th November.

Concerns about loss of parking spaces were raised and those involved in the project said at least 50% of roadside spaces would be allocated for residents’ permit parking, with the potential of more to follow. 

The £2m first phase aims to manage better surface and waste water from paths and roads – equivalent of the size of 10 football pitches – and plant trees and green spaces in streets which will better absorb the water.

The post-consultation, improved design for the Taff Embankment – with priority for cyclists and more residents’ parking. Top: How Blaenclydach Street will look – includes a rain garden and more residents’ parking.

It has been four years in the making and involves a partnership between Dwr Cymru Welsh Water, Natural Resources Wales and the council. ERH Communications have now been appointed as contractors.

The streets involved are: Aber Street, Abercynon Street, Bargoed Street, Blaenclydach Street, Taff Terrace, Taff Embankment, Coedcae Street, Cymmer Street, Clydach Street, Ferndale Street, Ystrad Street, Llanbradach Street.

At the moment, the excess rainwater is pumped eight miles out to sea, but soon it will be diverted into the River Taff by an underground pipe in each street after being “cleaned” by the trees, plants, soil and shrubbery above ground.

The by-product of course is that we will have street improvement and extra green areas – which themselves will encourage bees, birds and other wildlife.

The project will see 135 new trees planted, new habitats as well as new pavements and benches.

Designs for the road layouts can be seen here.


The issue of the lay-out of the road along the stretch of the Taff Embankment has also been raised, given that it is also part of the Taff Trail and cyclists have asked about traffic priority. The idea is that traffic calming will follow, with reduced speeds for motorists.

Cabinet member for transport, planning and sustainability, Councillor Ramesh Patel, said:  “This innovative partnership project represents a significant investment in the Grangetown area.

“Once completed the scheme will deliver real community benefits in the form of increased green space, increased provision for resident parking, improved cycling and active travel facilities as well as reducing our carbon footprint and improving the management of rainwater in the area.  This is a real step on the road to making Cardiff Europe’s most liveable capital city.”

It was summer 2015 when residents were shown the design details but it has taken an extra year to tie up final matters to proceed. 

Work on the project will be carried out in phases to minimise disruption to residents. It is expected to be complete in late 2017.

Dwr Cymru’s Steve Wilson said: “The Greener Grangetown project will help improve the way our network operates during heavy rain which in turn will bring clear environmental benefits for decades to come.”
