Kit PetersFLOOD FIX: Funding confirmed to finally tackle Killay Square and Gower road misery after years of chaos
Killay Square is finally set to get its long-awaited £800,000 flood fix — as Swansea Council confirms the funding that will tackle one of the city’s most persistent and disruptive road flooding problems.
The junction where Gower Road meets Goetre Fach Road and Goetre Fawr Road has been a byword for flood misery for years. When heavy rain arrives, stormwater pools so deeply across the junction that cars stall mid-road, pavements disappear entirely and bus services are diverted away from the area.
Historic flooding events have blocked access for emergency vehicles and caused damage to nearby homes and businesses. With climate change driving more intense and frequent storms, engineers have warned the situation will only worsen without intervention.
The fix engineers have designed involves a new 600mm overflow pipe running from the junction to the open watercourse behind Killay Library, which feeds into a tributary of the River Clyne. By splitting the flow between the existing drainage pipe and the new one, the system gains enough capacity to prevent the junction flooding during heavy downpours.
With £800,000 now confirmed as part of the 2026/27 transport programme, construction is expected to begin in late 2026. Work is estimated to last between six and nine months.

The Gower road at the A4118 between Llanddewi and Scurlage is also making progress — though at an earlier stage. The stretch of road is a key route for locals and visitors heading to the Gower coast, and can become completely impassable during heavy rain, leaving residents cut off and causing widespread disruption for motorists.
Funding has now been confirmed to design a flood alleviation scheme for the route, with construction expected to follow in a later phase once that design work is complete.
Council engineers have been studying a range of possible approaches for the Gower road. These include installing larger drainage pipes to carry higher volumes of water, improving connections between the drainage system and nearby streams, and potentially raising sections of the road to keep vehicles moving during the worst downpours.
Nature-based measures to slow the flow of water before it reaches the road have also been under consideration, alongside improved maintenance of the existing drainage network.
Both the Killay and Gower schemes have been in development for some time. An earlier round of Welsh Government Resilient Roads Fund money — around £265,000 — was used to investigate solutions at both sites.
That initial work informed the engineering design at Killay Square, which moved further along the process than the Gower scheme and is now funded for construction. The Gower road scheme, which entered public consultation earlier this year, is now progressing to the next stage with design funding confirmed.
The confirmation that both schemes are moving forward will come as significant relief for residents and businesses who have had to put up with the disruption for years. For many in Killay, the flooding has become a depressingly familiar seasonal spectacle — and one that, with the drainage fix now funded, should soon become a thing of the past.
On Gower, the road between Llanddewi and Scurlage presents different engineering challenges given its rural setting, but the principles are similar — getting water off the road more quickly and providing alternative routes for it to travel without causing wider damage.
Swansea Council’s Head of Service for Transport and Highways, Stuart Davies, said the funding would enable the council to deliver “a wide range of transport related projects that will benefit motorists, public transport users as well as pedestrians and cyclists.”
Both schemes form part of a broader £6.7 million transport investment package for Swansea in 2026/27, backed by Welsh Government regional transport fund money alongside UK Government contributions.
