A drainage blunder has stopped children being able to move into a brand new church school.
Pupils expecting to start the autumn term at Ysgol Llanfair Dyffryn Clwyd’s new site in Denbighshire will now have to suffer their old and cramped building until next year.
It comes after “unforeseen issues” connecting to the drainage networks emerged after the main building works were completed.
An issue between Welsh Water and the local authority meant that Denbighshire Council thought they could connect to a network on the public highway, when in fact drainage needed to be connected within the Neuadd Eleanor car park, which is owned by a third party.
The local authority has since been working with the land owner, trustees, agents, solicitors, Welsh Water and the Neuadd Eleanor committee to resolve the problem amid a lengthy legal process.
Meanwhile, foul drainage works had to be put on hold until contractors Wynne Construction were given approval to proceed.
Approval was only granted in September.
Once the drainage work is finished, builders will then need to complete works to the external areas including the forming of the main entrance and the new car park.
It means it will be next year before pupils can move in.
But some residents contacted North Wales Live to brand it as “incompetence”.
One man, who did not want to be named said: “Llanfair DC has a new school we are all delighted about.
“Unfortunately although the school is built and all appliances installed, the school is not open.
“Children have had to go to their old cold building.”
The resident said the reason the “mismanaged project” has stalled is because sewage wasn’t connected to the main drain.
They added: “Groundworks done, school built, fully stocked minus children. Incompetence again.”
The council said that, throughout the process, the school, governing body and Diocese of St Asaph have been provided with updates on the progress and are fully aware of the current position.
Helen Oldfield, headteacher of Ysgol Llanfair DC, said: “The project has been progressing well and the new facilities look fantastic.
“The next phase of the works is the final piece of the jigsaw and although the unforeseen issues with the foul drainage has been frustrating. We would like to thank Denbighshire for their efforts to resolve the matter.
“We are looking forward to the completion of these works and the new school opening.”
The new bilingual church school, jointly funded by the council and Welsh Government , will “provide a transformation of the teaching and learning environment”.
The council say it will “see pupils and teachers leave their cramped main building and mobile classrooms and see them move into state of the art facilities where for the first time they will have a main hall which will include a dining area away from their classrooms and bright and airy classrooms with direct access to the external areas”.
A spokesman for Denbighshire Council said: “The foul drainage connection works commenced at the end of September and completion is expected early next year.
“There will be a clearer indication on a confirmed move in date once the works have reached the mid-way point. The council will continue to engage with the school, the Diocese and the community on progress.”
A Welsh Water spokesman said: “As part of the planning process, we provided the applicant with a point of connection to our system… (it was) established that this point of connection was on third party land.
“We are aware that the council has engaged with the land owner to acquire access to ensure a connection can be made to our sewer network.
“We will continue to work closely with all the interested parties.”
