Ve­o­lia awarded con­tract for Vartry Wa­ter Plant up­grade

Wicklow People (Arklow) - - NEWS - BY MYLES BUCHANAN

THE Irish Wa­ter con­tract for the de­sign, con­struc­tion and com­mis­sion­ing of the new wa­ter treat­ment plant at the site of the Vartry Reser­voir has been awarded to Ve­o­lia Wa­ter Ire­land Ltd.

The con­struc­tion of the new wa­ter treat­ment plant is part of a €200m in­vest­ment in the Vartry Wa­ter Sup­ply Scheme, with works due to be­gin later this year and ex­pected to be com­pleted in 2020.

The scheme was orig­i­nally built in the 1860s and is in ur­gent need of im­prove­ment. It is also on the En­vi­ron­men­tal Pro­tec­tion Agency’s (EPA) Re­me­dial Ac­tion List (RAL) which iden­ti­fies wa­ter sup­plies that are in need of im­prove­ment to com­ply with drink­ing wa­ter reg­u­la­tions.

Ge­off O’Sul­li­van, Project Man­ager with Irish Wa­ter said: ‘The up­grade of the Vartry Wa­ter Sup­ply Scheme has been a pri­or­ity for Irish Wa­ter since the util­ity took over the re­spon­si­bil­ity for wa­ter ser­vices in 2014. I am pleased to con­firm that a con­tract has been awarded to com­mence work on this vi­tal project which will re­place the age­ing plant with a mod­ern fa­cil­ity, safe­guard­ing the wa­ter sup­ply for 200,000 peo­ple in Wick­low and south Dublin.

‘The scheme has had no ma­jor up­grade since it was built 150 years ago and is in ur­gent need of this in­vest­ment.

‘The con­struc­tion of a new wa­ter treat­ment plant at the ex­ist­ing Vartry reser­voir site is the next phase in a wider in­vest­ment project in the scheme which also in­cludes the con­struc­tion of a new 4km pipe­line from Cal­low Hill to the Vartry Wa­ter Treat­ment Plant and cov­er­ing the treated drink­ing wa­ter stor­age reser­voir at Stil­lor­gan. The in­vest­ment in the scheme en­sures that the peo­ple of Wick­low and south Dublin have a drink­ing wa­ter sup­ply that meets all drink­ing wa­ter reg­u­la­tions that safe­guards pub­lic health for gen­er­a­tions to come,’ said Mr O’Sul­li­van.

Irish Wa­ter has also com­mit­ted to pro­vid­ing a com­pen­sa­tion flow of five mil­lion litres per day into the River Vartry, which will pro­tect the ecol­ogy of the river dur­ing pe­ri­ods of low flow. The vol­ume of wa­ter ab­stracted will be the same level as it has been since the scheme was com­mis­sioned 150 years ago.

Mean­while, pipe lay­ing has pro­gressed to sched­ule as part of the con­struc­tion of a new link from the ex­ist­ing wa­ter treat­ment plant at the Vartry to Calowhill. The works started in Jan­uary of this year and are con­sid­ered a pri­or­ity el­e­ment of the over­all Vartry Wa­ter Scheme up­grade.

The works in­clude: a new pump­ing sta­tion at the ex­ist­ing plant and four kilo­me­tres of buried pipe­line from Vartry to Cal­lowhill and a break pres­sure tank at Cal­lowhill.

The fi­nal sec­tion of pipe has been laid and the con­struc­tion works will be mainly con­fined to the sites at Cal­lowhill Lower, the sum­mit break pres­sure tank and the Vartry Wa­ter Treat­ment Plant. The works should be com­pleted by De­cem­ber.
