Glenmore WTP Filter Upgrades:

Ø     This filter optimization program includes the removal and disposal of existing filter media, modifications to existing underdrain systems and the installation of a new Phoenix Underdrain System in three filter beds.

Ø     The phase is scheduled to be complete in February 2008.

Glenmore WTP Powder Activated Carbon:

Ø     This phase consists of the supply and installation of powder activated carbon storage and dosing system near the Glenmore Reservoir Dam. The carbon is used to control seasonal taste and odor anomalies.

Ø     The Request for Proposal for the equipment supply and the chemical supply has been issued.

Ø     This phase is scheduled to be completed by May 2008.

Glenmore WTP Carbon Dioxide System:

Ø     This phase consists of the installation of a carbon dioxide system to depress the pH of the raw water feed. 

Ø     A concrete foundation pad for the tank, piping from the tank to the rapid mix building, and the installation of mixing piping coils and eductor nozzles into the raw water supply pipes are included in the scope currently under design.

Ø     This phase is scheduled to be complete by June 2008.

Glenmore WTP Glenmore Reservoir Dam Work:

Ø     This phase will consist of construction management for the refurbishment of the twelve foot diameter dow valve disks and their actuators and refurbishment of the penstock for the dam's low level outlet.

Ø     Klohn Crippen Berger is the consultant responsible for the work in relation to the dam.

Ø     Testing of anchors in the stilling basin will also be conducted to satisfy dam safety monitoring.

Ø     This phase is scheduled to be complete by March 2009. One disk will be removed and the corresponding penstock will be refurbished each winter (2007/2008 and 2008/2009).

Glenmore WTP Residuals & Pretreatment Facility:

Ø     This phase consists of an integrated structure combining four Actiflo pretreatment trains and the residuals thickening and sludge dewatering process.

Ø     The project is at a ninety percent design level and budget updates have been submitted based on the ninety percent drawings.

Ø     This phase will consist of 8,450 cubic metres of structural concrete and 5,825 cubic metres for lean mix fill, 24,700 square metres of formwork in a 3,720 square metre building footprint.

Ø     The Residuals Equalization Tank substructure was tendered early so that the excavation would not interfere with work on the main structure.

Ø     The Residuals Equalization Tank substructure will consist of 1,480 cubic metres of structural concrete, 1,250 cubic metres of non-shrinkable fill and 3,950 square metres of formwork.

Ø     This phase is scheduled to be commissioned by May 2011.

Bearspaw WTP Residuals Treatment Facility:

Ø     Drilling of 526 rock-socketed and compacto piles that include a significant excavation and shoring program.

Ø     A challenging structure with 7,900 cubic meters of concrete placement, complex formwork combined with a stringent concrete quality control specification.

Ø     Installation of 3,000 lineal meters of water stop combined with sandblasting and pressure to all concrete joint locations. 

Ø     Hydrostatic water testing of sixteen water tank structures, thickener tanks, floc cells, effluent channels and equalization tanks.

Ø     Procurement for owner-supplied equipment; thickener/clarifier equipment, electrical switchgear, motor control centers and transformers, centrifuge, dechlorination and polymer feed equipment.

Ø     This phase was substantially complete on June 18, 2007 and is in the final stages of commissioning.

Bearspaw WTP Pretreatment Facility:

Ø     Demolition of the existing sedimentation basin that made way for the new Pretreatment Facility.  Demolished concrete was recycled and used for site roads and backfill accordingly.

Ø     Drilling of 381 rock-socketed piles and additional seventy-six piles for Valve Chamber 10.

Ø     10,200 cubic meters of concrete placed including Valve Chamber 10. 

Ø     Installation of 2,400 lineal meters of water stop placement combined with sandblasting and pressure wash to all concrete joint locations.

Ø     Thirty-three water retaining tank structures tested to meet the specified hydrostatic water requirements.   

Ø     Procurement of owner-supplied Actiflo equipment for s

Glenmore WTP Sodium Hypochlorite Facility:  The Sodium Hypochlorite Facility is the second stage of expansion at the City of Calgary's Glenmore Water Treatment Plant. This Facility will eliminate the use of gaseous chlorine for disinfection of the City's potable water supply, replacing it with salt generated sodium hypochlorite. The Sodium Hypochlorite Facility is scheduled to start commissioning in January 2008 and finish in February 2008 with plant take over by the City of Calgary in March 2008. Currently, concrete work is 90% complete and masonry is commencing.

Bearspaw WTP Residuals Treatment Facility:  The Residuals Treatment Facility will be the first of two facilities to be added to the City of Calgary's Bearspaw Water Treatment Plant's potable water processing system. The Residuals facility will remove solid waste from the waste water generated through the treatment system, eliminating the process of residuals that are currently being discharged to Calgary's Bow River. The Residuals Facility is scheduled to be commissioned starting in January 2007 and finishing in March 2007. Currently all systems are complete and coordination schedules for equipment vendor representatives is in progress.  The City of Calgary assumed control of the plant in June 2007. 

Bearspaw WTP Pretreatment Facility:  The Pretreatment Facility will be the second of two facilities added to the City of Calgary's Bearspaw Water Treatment Plant's potable water processing systems. The Pretreatment facility will lessen the demand on the existing treatment process by pre-treating water taken from the Bow River and/or circulated from the Residuals Treatment facility, removing solids prior to water entering the existing plant. The Pretreatment facility is scheduled to be commissioned starting in October 2007 and finishing in January 2008 (pending City water demands). 

Bearspaw WTP Landscaping: This final phase is currently underway and will be completeby end of 2007.
