April 2, 2019

Stantec is proud to be participating in the 2019 OWWA Conference in Ottawa with a number of presentations by our Water specialists


A team of Stantec specialists are presenting at Ontario’s Water Conference & Trade Show. From water distribution to water treatment, our presenter’s will be discussing the successes and challenges of a large diameter watermain project, water hydraulic model protocols, manganese treatment and the design, construction and operation of intermediate ozone systems.

A Designer’s Perspective – Successes and Challenges of a Large Diameter Watermain Project

Presenter: Gregory Chochlinski 
Additional Authors: Kevin Alemany, Jeffrey Waara
Time and Date: Tuesday, May 7 from 10 am to 10:30 am
Stream: Distribution
Abstract: The OWEL watermain, a 7300m long 914mm/762mm diameter watermain was constructed to provide capacity and reliability in the City of Ottawa’s water distribution network. Various construction methods were used to overcome obstacles including Horizontal Direction Drilling, Jacking and Boring, Cast in Place Lining and a Stopple valve.

Follow the Protocols – Developing a Series of Protocols for a Potable Water Hydraulic Model Build – from Data Gathering and GIS Integration to Model Calibration and Analysis

Presenter: Kevin Alemany
Time and Date: Tuesday, May 7 from 11 am to 11:30 am
Stream: Distribution
Abstract: Stantec Consulting and Prince William County Service Authority developed 25 protocols and several supporting technical reports outlining the steps to incorporate existing databases, supplemented with an intensive field data gathering process to develop, calibrate and implement a new potable water hydraulic model, a major step towards a Smart Water System.


Manganese: It’s Not Just a Groundwater Problem

Author: David Pernitsky
Time and Date: Tuesday, May 7 from 2:45 pm to 3:15 pm
Stream: Treatment
Abstract: Causes of manganese fluctuations in surface waters will be presented along with a case study that details the response of one utility that was able to rapidly and effectively implement a manganese treatment solution at their WTP in a matter of weeks in response to a major raw water upset.


Intermediate Ozonation – From Design to Operations

Author: Maxime Beaulieu
Time and Date: Wednesday, May 8 from 8:30 am to 9:00 am
Stream: Treatment
Abstract: The present technical paper addresses issues related to design, construction and operation of intermediate ozone systems for municipal drinking water applications to aid utilities considering adding new or upgrading existing plant infrastructure. Two recent intermediate ozonation projects are presented to highlight specific design considerations, challenges during construction and operational experiences.


A Firsthand Experience of Using Carbon Fiber Reinforced Polymer (CFRP) for Large Diameter Pipe Rehabilitation in the City of Ottawa

Presenter: Jeffrey Waara
Additional Author: Gregory Chochlinski
Time and Date: May 7 from 2:15 – 2:45
Stream: Construction
Abstract: In 2018, the City of Ottawa inspected a critical large 1524mm diameter watermain and identified it to be at risk of imminent failure. A trenchless solution using Carbon Fiber Reinforced Polymer (CFRP) was ultimately selected as the preferred rehabilitation method and was installed over a period of 8 weeks.

Paying for an Inheritance: Dealing with Legacy Manganese in Drinking Water Systems

Presenter: Simon Horsley
Date and Time: May 7 from 3:45 pm to 4:15 pm
Stream: Distribution
Abstract: Manganese is both interesting and challenging in how it behaves in drinking water systems because it’s potential to cause discoloration changes according to localized water quality and hydraulic conditions. This presentation will review strategies to monitor and mitigate manganese deposits including practical illustrations by case study.
