Little P.Eng. Engineering provides specialized tanks and reservoirs engineering design, 3D modeling, structural analysis, and detailed engineering drawings across the USA and Canada. From industrial storage tanks and water reservoirs to process tanks and large-capacity containment systems, our Professional Engineering team develops practical, code-compliant solutions for new construction, modifications, rehabilitation, and facility expansion projects.

Comprehensive Tank and Reservoir Engineering Design
Tanks and reservoirs are critical components of industrial, municipal, energy, mining, chemical, water, wastewater, and manufacturing facilities. Their engineering requires careful consideration of stored liquid properties, hydrostatic pressure, operating conditions, environmental loads, corrosion allowances, foundations, connections, and structural stability.
Little P.Eng. Engineering provides engineering services for:
Above-ground steel storage tanks
Industrial water storage tanks
Firewater tanks and reservoirs
Process and chemical storage tanks
Municipal water reservoirs
Wastewater storage and treatment tanks
Oil and petroleum storage tanks
Large-diameter welded steel tanks
Rectangular and circular reservoirs
Tank foundations and anchorage systems
Tank roofs, platforms, stairs, ladders, and access structures
Our engineers evaluate dead load, hydrostatic pressure, wind, snow, seismic forces, temperature effects, settlement, uplift, overturning, and operational loads to develop reliable storage systems suitable for site-specific conditions.
Tank Structural Analysis and Code Compliance
Little P.Eng. Engineering performs detailed structural calculations using applicable project requirements and recognized engineering standards. Depending on the tank type, material, location, and application, engineering may incorporate requirements from API 650, API 620, AWWA standards, ASME requirements, NBCC, IBC, ASCE 7, AISC, CSA standards, and applicable provincial, state, and local building codes.
Engineering evaluations can include shell and plate thickness, roof structures, stiffening rings, wind girders, anchors, base plates, foundation reactions, seismic overturning, sliding resistance, uplift, nozzle reinforcement, and localized structural loads.
For existing facilities, our engineering team can also evaluate tank modifications, new penetrations, equipment additions, platforms, piping connections, structural reinforcement, and rehabilitation requirements.
3D Modeling for Tanks and Reservoirs
Modern tank projects benefit significantly from coordinated 3D engineering modeling. Little P.Eng. Engineering develops detailed models to help owners, fabricators, contractors, and other engineering disciplines visualize the complete installation before fabrication and construction.
3D models can incorporate tank shells, roofs, floors, nozzles, manways, piping interfaces, platforms, stairs, ladders, structural framing, supports, equipment, foundations, and surrounding facility components.
This coordinated approach helps identify interferences and constructability issues, improve nozzle and equipment positioning, coordinate piping connections, and reduce costly field modifications.
Detailed Engineering and Fabrication Drawings
Little P.Eng. Engineering transforms engineering calculations and 3D models into clear, coordinated engineering drawings for tanks and reservoirs. Drawing packages can be developed according to project scope and fabrication requirements.
Typical deliverables include:
General arrangement drawings
Tank plans, elevations, and sections
Shell and roof details
Nozzle and manway layouts
Foundation and anchorage drawings
Structural steel and support details
Platforms, ladders, stairs, and access details
Connection and reinforcement details
Piping interface drawings
Fabrication and construction details
Our goal is to provide drawing packages that support efficient coordination between owners, engineers, fabricators, contractors, and construction teams.
