To ask the Scottish Government whether it is aware of any problems with Scottish Water’s Old Meldrum project; if so, what issues have arisen, and what the (a) original and (b) final cost of the work was.
As this is an operational matter for Scottish Water, and the Scottish Government does not hold the information, I have asked them to respond. Their reply is as follows:
Scottish Water’s in-house capital project delivery team was asked to deliver a project to provide capacity for growth at Oldmeldrum Wastewater Treatment Works. The project involved cleaning of an existing aeration ditch, replacement of its mechanical rotors and installation of an innovative secondary treatment unit. The renewal of the aeration ditch was delivered successfully, but the innovative element of the project was found not to be suitable in combination with the existing treatment process at the site. The forecast cost of the project was £3.3 million and the final cost was £3.9 million.
