This powerpoint presentation begins by providing a brief overview of the Regional Municipality of Waterloo, and the Middleton Water Supply System's problem with low-level contamination by Trichloroethylene (TCE). Treatment alternatives are presented, and Advanced Oxidation Process (AOP) using ultraviolet (UV) plus hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) was
selected as the preferred alternative by the Region. Implementation of Interim Treatment approach is presented, along with design general concept, implementation timeline, fabrication/preparation, G3 preparation, site modifications, permitting, installation, and start-up. Presentation summary includes: unique delivery with Region acting as contractor for site and supplier
acting as contractor for a "turn-key" process;
five months from date of PO issuance to having finished containers on site
for final hook-up;
water running on June 8, 2009;
less intensive permitting required due to temporary nature of works;
coordination of supplier, fabricator, and site trades was critical;
required balance of long-term vs temporary decision-making for
several items -
well pumping, VFD,
well control, PLC and SCADA,
drain lines and service water,
reusability of equipment for long term use; and,
success was achieved by effective communication between all
stakeholders. Includes figures.
