PROJECTS AND PROFESSIONAL ACTIVITIES
Jean-Luc Daviau is a water resources engineer with over 12 years of experience in hydraulic and watershed studies, forensic/legal investigations, flow monitoring, hydrotechnical design and urban drainage / stormwater management (SWM). He is a skilled physical and numerical modeler using deterministic or stochastic methods (2 years on NSERC strategic GREHYS team). Jean-Luc is fluently bilingual in French and English and is a proven technical writer and trainer. EHG's lead forensic engineer, he is also lead instructor for Haestad Methods' HAMMER^® transient software. He contributes practical and multi-sector expertise for plants, pipelines and CSO tunnel systems.

Hydraulic transients for over 100 water, sanitary and slurry systems with key projects in:

MINING:  QIT Fer et Titane’s UGS-ALP plant transient pressures and forces for liquid and steam systems with high-temperature piping (Québec); Algoma 265 bar descaling system transient pressures & piping forces; Newmont water pipeline review (Nevada); Bulyanhulu water transmission line review (Tanzania); plant-wide review and hydraulic designs for slurry and water systems at Barrick Gold's Pascua Lama (Argentina), Boulder mine dewatering WTP (Nevada) and Roaster slurry pumping (Nevada).

WASTE:   Hydraulic transient analyses of deep sewers for City of Ottawa (Orleans-Cumberland collector and SWSF tunnel), City of Toronto (Western Beaches Tunnel) and the City of Edmonton. Surge, surcharge and Class EA for Fennel/Greenhill drop shaft, trunk sewer and CSO tank; including public meeting. Steady and transient analysis of Munster Hamlet PS and forcemain. Many similar analyses: Bolton PS, Binbrook PS, etc…

WATER:   Network-wide analysis of PD4 and Downsview Base and Area (Toronto); entire City of Thunder Bay; Zone 1W and LPTM (Ottawa). Five PS and ten zones for 40 km, 2100 mm pipeline (Peel to York). Review of 60 km, 600 mm Collingwood-Alliston line incl. network and extension to Beeton. Break investigation for Corrections Canada.

PLANTS:  R.C. Harris WTP, Ellesmere PS and Humber WWTP and co-generation (Toronto). WTP review and PS (Chatham). Woodward WWTP headworks and Greenhill CSO tank system (Hamilton). Event investigation for Ontario Power Generation and other plants.

Forensic Investigations and ADR

Engineering coordinator on flooding and erosion legal cases: Markland Woods Golf (MTO) and Oakdale Golf (plaintiff) – latter subject to case management and ADR (both settled). Confidential pre-trial/break investigations and value engineering. Lead EHG forensic engineer.

Field Tests and Monitoring

Eight pump curves, NPSH and suction system tests for PS in Toronto, Peel and Chatham. Five millisecond logging on 265 bar de-scaling system (Algoma) and high pressure & temperature systems at QIT Fer et Titane (fluid and steam). Several pump station, valve and hydrant flow & pressure tests in the City of Thunder Bay. Post-construction monitoring plan and installation for 9th line SWM pond water quality retrofit. Several insertable flumes for sanitary infill capacity studies and modeling using SANSYS. Installation, calibration & operation of network of 3 rain gauges, 3 ISCO automatic water quality samplers and 3 floats at three SWM ponds for City of Ottawa; analysis of flows/levels to assess infiltration/inflow (I/I) at 28 sites for 7 years.

Physical (Scale) Models of Hydraulic Structures

Project manager for 30 x 4 m, 1:12 scale model of CSO drop shaft system in City of Hamilton; plus assistance with review of receiving sewer CSO tank system and Class EA. Designed 10 m long 1:10 scale model of gravity sewer to study transitions from open channel to pressure flow.

Environmental Assessment

EA and site selection for several feedermains and reservoirs (Peel and York). Greenhill drop shaft & CSO tank (Hamilton). Hawkesbury Ck. relocation (Ottawa) and Carp R. flow restoration (Thunder Bay) studies, both with biologists. Long-term study for urban lake (Markham).

Water Supply

Water Supply and distribution studies for Toronto, Ottawa, Thunder Bay, Alliston and Chatham. In Greater Toronto Area (GTA): Peel-York 2100 mm feedermains, Durham, Downsview Base Lands Re-development in PD5 & 6; Ellesmere PS upgrade in PD2 & 4, etc...

Watershed Studies & Urban Drainage

Deterministic & stochastic models of flooding & erosion in Etobicoke Ck. & Black Ck for two legal cases. Revision of Dyment Ck. model (OTTHYMO, 556 ha). Revision and sensitivity analysis of Cardinal Ck. MDP (3,276 ha). Many sub-watershed studies. Avalon subdivision (656 ha). Rapid evaluation of Lawrence Ave. E. crossing of Wilkett Creek (Toronto). Review of over 50 culverts, median drainage optimization and impact of 16 Mile Ck. bridge piers on backwater levels for West Extension of HWY 407 ETR (3 jobs); 70 culverts for HWY 5 (CulvertMaster). Retrofit of SWM pond to handle roadway pollutant loading (STORM).

Geographic Information Systems (GIS)

Analysis of floods at 189 stations in Ontario and Quebec using SPANS GIS (thesis). Preparation of Dyment's Creek watershed data for loading into Barrie's GIS. Development of procedures for the use of SIMS (storm sewer) data for SWM and for the inventory of drainage features for the Town of Markham. Water distribution network analysis using ArcView linked to Cybernet (now WaterGEMS) for WASA, Trinidad & Tobago.
