Prior to each filter are dedicated flocculation zones and a coagulation zone, which is common to each of two floc/filter train. - The TTF contains chemical storage and dosing facilities, chlorination system for effluent water system and laboratory and office spaces. The new building is fed with new utilities and roads and staff parking surround the building. - Associated tie-ins. - Start-up and Commissioning of this project component. - Civil and landscaping works involving erosion and sediment control, tree removals, clearing, grubbing, topsoil stripping, excavation, offsite fill disposal, yard piping installation, backfilling, compaction, rough grading, fine grading, paving, sidewalk installation, tree planting, landscaping and associated works.
