Hydraulic transients for over
100 water, sanitary and slurry systems:
Entire water networks such as pressure district 4 (Toronto), Glenmore/Top Hill system
(Calgary); Zone 1W and LPTM, including forces (Ottawa); 3 zones in Thunder Bay; Zones 2 to 6
(Region of Peel) and 6 to 8 (York Region) and smaller municipalities. Rapid assessment
of transient risks for DeCew Falls system (Niagara); Region of Ottawa-Carleton; Aurora to
Newmarket line (York Region); and line from Keswick to Sutton (Georgina Township).
Transients analysis of surcharged trunk sewers and WWTP in Edmonton
(confirmed by independent lab tests) and Ottawa (Orleans-Cumberland). Pre-design and review of
Western Beaches CSO storage Tunnel (Toronto). Designs for Somerset tunnel (Ottawa). Review
of York-Durham Sanitary Sewer System (YDSS) and designs for many hydraulic structures.
Surge control applications including: (i) valves for Zone 5 watermains
(Hamilton), 8 PS in Peel (Ontario), Montego Bay (Jamaica) and Kabul (Afghanistan) water systems;
(ii) tanks for New Tecumseth line (Ontario), Deacon booster PS (Winnipeg) and Buffalo Pound line
(Regina), and (iii) gas vessels for Lake Huron raw water (London), Easterly and Humber STP (Toronto),
Airport Rd line (Peel and York) and Longeuil forcemain (Montréal).
End-to-end hydraulic reviews and transient control for mining and industrial plants
including Boulder mine dewatering WTP and Roaster slurry pumping for Barrick Gold and gravity
line for Newmont Gold (all in Nevada); Pascua Lama mine (Argentina/Chile); Bulyanhulu water
line (Tanzania); QIT Fer et Titane plant with high pressures and temperatures plus steam system
(Quebec) and Algoma 265 bar descaling system – both with transient forces on piping for input to
CAESAR II pipe stress analysis (by others).
Break investigations and project reviews and/or legal cases for
dozens of pump stations, hydropower penstocks, plants and pipelines on four continents.
Expert Witness and ADR
Expert witness on flooding and erosion cases: Markland Woods Golf (MTO) and Oakdale Golf
(plaintiff), the latter subject to case management and ADR (both settled). Confidential pre-trial
investigations for 5 other cases, plus dozens of reviews and break investigations as owner’s
expert or through value engineering. Built an experienced field and forensic engineering team.
Physical Modelling of Hydraulic Structures
Field tracer study for Brampton chlorine contact chamber. Scale models of chlorine mixing for
the Glen Cairn and Ottawa South reservoirs in the City of Ottawa. Lab tests of PVC pipe under
vacuum and overpressure for Ontario Ministry of Environment. Hydraulic reviews of Vaughan
YDSS meter chamber and Kerrowood outfall (York Region).
Environmental Assessment
EA and site selection for several feedermains and reservoirs (Peel and York): Greenhill drop
shaft and CSO tank (Hamilton), Point Lepreau nuclear plant (New Brunswick) and Lower
Churchill hydro plant (Newfoundland). Al Masane mine (Saudi Arabia).
Water Supply
Water Supply and distribution studies for Toronto, Region of Waterloo (Tri-City surface and
groundwater sources), Ottawa (hydraulic review of entire system), Hamilton-Wentworth,
Simcoe Region, New-Tecumseth transmission pipeline, Sault Ste. Marie, Town of Taber
(Alberta), Calgary (Alberta), St. John (New Brunswick), Montego Bay (Jamaica) and Kabul
(Afganistan). Major work in Greater Toronto Area (GTA): Peel-York 2100 mm feedermains,
Downsview Base Lands Re-development in PD5 & 6; Ellesmere PS upgrade in PD2 & 4;
Block 17 in Vaughan; Oakville Zone 2; Fieldrun Phase III water system and more.
Water Pollution Control
Pollution control studies for existing wastewater collection systems for Calgary, Edmonton,
Winnipeg, St. Catherines, Toronto and St. John. Design and hydraulic operations for water and
waste treatment plants for R.C. Harris, Humber and Dufferin (Toronto); Thunder Bay (Ontario)
and Boulder Valley (Nevada). Technical reviews of CSO tanks and tunnels in Toronto
(Western Beaches), Ottawa (SWSF) and Hamilton (Greenhill).
Dispersion Analysis
Chlorine dispersion from a snow disposal site near Ottawa River and from petroleum plants
along St. Clair River. Thermal discharge study by computer modelling and dye diffusion for
Dalhousie power plant and Point Lepreau nuclear plant (New Brunswick).
Shoreline Protection
Physical model studies of wave effects for site selection of point Lepreau nuclear station
(New Brunswick). Analysis and design work for Lepreau intake and outfall alternatives.
