Welsh Water kicks off £9million investment to boost Rhondda drinking water


Welsh Water has started work on an £9 million pound investment scheme which will ensure around 10,000 customers in the Rhondda Valleys continue to receive a top quality drinking water supply.

Work to upgrade the water treatment works at Tynywaun, Treherbert will see a new treatment process introduced at the site.  This will ensure the works, which operates around the clock, continues to meet the highest drinking water quality standards. 

The work, which is set to be completed by March 2018, forms part of the £1.7 billion investment the not for profit company will be spending up until 2020 in further improving services to customers and protecting the environment.   

To mark the start of the work, local Assembly Member Leanne Wood and local councillors Irene Pearce and Geraint Davies visited the site to cut the first turf.

Welsh Water’s Project Manager for the project, Karen Morris said: “Our £9 million investment reflects our commitment to provide customers in the area with a first class drinking water supply direct to their taps.  The treatment works has served the area well over the years and our investment will ensure it continues to do so for decades to come.

“We have engaged with the local community about the work and are committed to keeping them informed as we progress with this essential scheme”.

Local Assembly Member Leanne Wood said:  “It’s good that Welsh Water is investing so much in this treatment works.   It serves people across the whole of the Rhondda and so will benefit many households. This is a significant investment in our area.  I look forward to seeing how it progresses over the coming months”.

The work will involve the construction of new buildings to house the new treatment process.  These will be built within the site, next to the existing treatment works and will be mostly concealed from view by trees.  The buildings will be sympathetic to their surroundings and similar to those already on site.  

Over the course of the coming weeks, local residents will likely notice an increase in activity at the site as work gets underway.

Karen added: “This is one of the largest investment schemes we are undertaking as a company and requires various materials to be brought to site so that we can get things started.  We will be writing to local residents to explain exactly what will be going on over course of next few weeks to ensure they are kept fully up to date with what is going on.  We’ll of course ensure we do everything to cause the least impact possible on the local community during our work”.

Earlier this year, Welsh Water supported the local Blaenycwm Chapel Community Garden by helping with preparations for a summer garden party by strimming the grass, weeding, raking, sweeping and a helping with general clean-up of the gardens.

The team also built a picnic table, two benches and a bird table which they donated to the gardens for the local community. They also arranged for an external tap to be fitted so the community group has easier access to water.
