Anne Street North Zone 2 and Zone 3 Water Booster Pumping Station

The Anne St Reservoir is located within Zone 1 of the City of Barrie’s Water Distribution System. There is an existing booster pumping station (BPS) that pumps water to Zone 2N. A complete rebuild of the existing Zone 2N Pumping Station is provided as the existing station is reaching the end of its life expectancy and is in need of major refurbishing.

ETO Engineering is retained by the City of Barrie to provide professional engineering services to rebuild the existing BPS to replace the existing Anne St BPS feeding water distribution to Zone 2N and to include a new booster pumping system arrangement feeding Zone 3N all housed within one common new BPS.

Keswick WRRF Aeration System Upgrade

The Keswick Water Resource Recovery Facility (WRRF) is an extended aeration treatment plant equipped with tertiary ultra-filtration membranes. The existing process aeration system consists of four (4) 200 HP (150 kW) multi-stage centrifugal blowers (3 duty, one standby), each capable of supplying approximately 5,316 m3/hr of airflow. The blowers are located in the lower level Aeration Blower Gallery, complete with inlet valves used to regulate blower output.

ETO Engineering is retained by the York Region to identify risks and opportunities within the aeration system. ETO will provide professional engineering services to assess the existing aeration system capacity, upgrade the aeration system with the state-of-the-art process equipment and advanced control systems to achieve overall energy savings. A new Ammonia Based Aeration Control (ABAC) will be piloted and implemented in addition to various upgrades to the system.

Mechanical, Electrical and Fuel System Upgrades Related TSSA Compliance at Various Pumping Stations and Bayshore WWPS Upgrades

The Regional Municipality of Halton has identified thiry-one (31) Water, Wastewater and Stormwater facilities that require civil, mechanical and fuel system upgrades in order to maintain the water distribution system and wastewater collection system in a state of good repair. The Halton Region also intends to upgrade the Bayshore WWPS by adding a new emergency standby diesel generator.

ETO Engineering is retained by Halton Region as the Prime Consultant for the Design, Contract Tender Preparation, Contract Administration, Project Management and all Construction Field Services (provisional) including Contract Administration and Construction Inspection.

Contract Administration for Construction of King City Booster Pumping Station

The King City Booster Pumping Station Project is located at 12640 Dufferin Street in the Township of King. The new pumping station is constructed at the site of an existing elevated tank (Dufferin Street and Fisher Street). Under this project, the King City Booster Pump Station replaces the existing temporary diesel pumps and supplies water from the Pressure District 8 (PD8) watermain to the King City Elevated Tank Dufferin Street (KCETDS), and also to King City Elevated Tank Fisher Street (KCETFS).

ETO Engineering is retained by the York Region as the Prime Consultant for the two-year construction Contract Administration, site inspection, SCADA programming and system commissioning. This new infrastructure construction project includes a full scope of architectural, structural, civil, process, HVAC, electrical and instrumentation control.

Maple Pumping Station Capacity Expansion

Maple Pumping Station, which is the largest pumping facility within the Region’s Water Distribution System, is located at 10588 Keele Street in the City of Vaughan. It is a two-zone pumping station, which pumps water from Maple Reservoir (90 ML) to Pressure District 7 (PD7) and Pressure District 8 (PD8), with two separate sets of pumps.

Building on the success of the PD7 upgrade, ETO Engineering is retained once again as the Prime Consultant for the PD8 pumping system upgrade. ETO will be responsible for the overall project delivery including Preliminary Design, Detailed Design, Construction Contract Administration and Commissioning.

F.M. Woods Pumping Station Discharge Replacement

Woods Pumping Station was constructed in 1981 and is the largest within the water distribution system of the City of Guelph. The process equipment are of the original construction and are showing signs of wear ant tear. In particular, the discharge valve of Pump No.1 (284L/s, 350HP, 4160V) is leaking significantly and is at high risk of failure. Pump No.1 discharge header was replaced in 2013. The purpose of this repair project is to replace the discharge headers for Pump No.2 (375L/s, 450HP) and No.3 (300L/s, 350HP), complete with with a motorized valve, check valve, air valve, piping, electrical and SCADA work.

ETO Engineering was retained by the City of Guelph for this State-of-Good-Repair (SOGR) project at F. M. Woods Pumping Station.

Samsung LCD Wastewater Reuse

This is a membrane bioreactor (MBR) wastewater reuse project for Samsung Electronics, located in Cheonan, South Korea. It has an average daily flow (ADF) of 2150 m3/day treating the high strength wastewater generated from the liquid crystal display (LCD) manufacturing facility. Various chemicals and solvent waste at the LCD plant were collected and pH neutralized, prior to entering an extended aeration process followed by a four-train membrane bioreactor (MBR) system. Permeate of membrane passes through two activated carbon beds before final discharge.

ETO Engineering was retained by Samsung / Lotte Chemical as the MBR specialist on a multiple year consulting contract to provide process design, training, commissioning and troubleshooting services. For the C1 project, ETO Engineering was responsible for the overall process development, MBR system design, start-up, commissioning and trouble shooting.

Gormley Pump Station Upgrade

Originally constructed by a local Land Developer, the existing Gormley Pumping Station was built to pump and store well water in two above-ground silos to meet the Fire Department’s requirement for water services to fill fire trucks in the area. Ownership of the facility has recently transferred to the Town of Whitchurch-Stouffville (the Town). The town has since noted a few mechanical and operational issues. Also it is mandated that the current power source from the Developer's Utility Room to be relocated to an independent power supply from Hydro One.

The Town retained ETO as the engineering consultant of a Design/Build team to manage and coordinate the Gormley Pumping Station Upgrades. ETO provided all engineering and design services to the D/B project.

YARA Industrial Wastewater Treatment and Reuse

At Yara’s fertilizer manufacturing facility, local storm water and the plant waste water are sent to six large evaporation ponds, with the first two ponds originally designed and constructed in 1991. According to plant records, the storm water collected at site contributes the most volume, up to 50% of all inflow loading, to the evaporation ponds depending on the precipitation on the plant facility catchment area. The storm water was originally planned to use as the raw water source to feed the existing water treatment plant. The current practice is however to pump it into the evaporation ponds due to the high nitrogen content. Typical range of the storm water characteristics show as follows:
• pH = 9.0
• TOC = 81-240 mg/L
• TKN = 274-987 mg/L
• NH3-N = 151-410 mg/L
• Alkalinity as CaCO3 = 492-1330 mg/L
• TDS = 588-992 mg/L
• Hardness as CaCO3 = 120-330 mg/L

Innovative Solution

Following a feasibility study with the operational staff at YARA, a treatment and reuse strategy is elected to reduce load to the existing evaporation ponds. There are many engineering and technical challenges with this project, e.g. seasonal temperature and characteristic change.  A state-of-the-art dual-membrane process is proposed to treat the storm water for reuse as an alternative water source to solve the water balance problem. Depending upon the treated water quality, it may be used as cooling tower makeup, or high purity water in the plant process.
