Directions:
The Welsh Water head office is unsurprisingly located in Wales. It is accessible by car from the A470 and the A472, or from the nearby Nelson or Quaker’s Yard. There is a car park on the site and bus stops on the road outside. The bus routes which go this way are the 78, E78, and S79, which travel through both nearby villages. The closest train station is 2 miles away at Quaker’s Yard for Transport for Wales trains. You can walk 3 minutes to Treharne Road and catch the 78 bus to the Welsh Water offices. This bus journey will take around half an hour.
