Agenda item

Erection of pre-treatment and bromate removal facility comprising  four new buildings:-i) pre-treatment building.ii) chemical storage and dosing building iii) catalytic GAC building/structure and iv) washwater recovery building/structure:

Associated plant and machinery and new access arrangements to the site including constructions of temporary crossings of New River for construction traffic and extension of estates road from within New river Village ( New River Avenue N8) for delivery vehicles only.

RECOMMENDATION: To grant planning permission subject to a section 106 and agreement and planning conditions and subject to referral to the Greater London Authority who have 14 days in which to decide whether or not to direct refusal. 

 

 

Officers presented the report by advising the Committee that this application was for a water treatment plant to ensure that clean water was maintained for this part of London.  The applicant would be required to enter into a Section 106 legal agreement with contributions of additional planting within Alexandra Palace grounds to screen views from the palace and park, improvement to Penstock Path and a contribution to the Play scheme.  Members were also asked to note that the application had to be submitted to GOL for approval. 

 

Objectors spoke on behalf of local residents who felt the water treatment works need not be located at this site.  However they appreciated there was a requirement for a treatment plant and had found an alternative site in Enfield.  Thames Water however disputed this as it was too small for a treatment plant.  Members were also advised that the previous application had been refused on the ground of design and that this had not been changed in this application.  Concerns were raised on the poorly displayed montages and  contested the accuracy of the designs in that computer graphics could distort and misinterpret open spaces.

 

Cllr Gorrie also spoke on behalf of local residents as he had attended the Development Forum meeting.  He raised concern over access to the site by large construction vehicles and chemicals being delivered via New River Village which would reduce the attractiveness of the visual amenity.

 

The applicant’s representative advised the Committee that this was the third application submitted and that they believed was the most acceptable.  Thames Water had a statutory duty to develop and maintain water supply in the area and that the current proposal would ensure that improved clean water was provided and maintained for this part of London.   There were special circumstances for this proposal which had addressed the previous reasons for refusal.

 

The Chair moved a motion to grant the application.  Members voted 4 in favour, 2 against and 3 abstentions.   The application was agreed, subject to it being referred to the GLA and GOL and subject to conditions and Section 106 legal agreement.
