Hydraulics Engineer Water Services

Role Summary

We are seeking a Hydraulics Engineer (Design) to lead Task C — Assessment and Update of the Design Package for the city’s dewatering systems. The role assesses and modernizes the design criteria, methodology, specifications and tender documents, and analyzes dewatering-system alternatives to recommend the optimum system for each area.

This is the hydraulic-design authority for the program: it owns the dewatering design standards, produces reusable tender packages, reviews third-party technical submittals, delivers urgent detailed designs on request, and investigates water-rise complaints to propose practical solutions. The role’s hydraulic expertise also informs the water-balance and modeling tasks.

Accountability

The Hydraulics Engineer is accountable for a modernized, defensible dewatering design package — criteria, specifications and tender templates — for optimum-system recommendations per area, for timely review of third-party submittals and urgent designs, and for hydraulic input consistent with the water-balance and modeling tasks.

Key Competencies

Dewatering design – Owns design criteria, methodology and specifications for dewatering and drainage systems.

Alternatives analysis – Selects the optimum dewatering system per area against governing parameters.

Tender packages – Produces reusable, review-ready design templates and tender documents.

Submittal review – Reviews and approves third-party designs and running-project changes.

Hydraulic modeling – Supports design with 1D network and 2D overland-flow analysis.

Value engineering – Targets whole-of-life effectiveness and cost across design choices.

Core Responsibilities (Task C)

1.1 Design-Package Assessment & Update

Revise and assess the current design package — design criteria, methodology, specifications, drawings, details, materials and tender documents.

Update the design package to the newest technologies and establish design templates and tender documents for future projects.

Design a detailed integrated training program (design, modeling, monitoring) for client staff.

1.2 Dewatering-System Alternatives & Optimization

Analyze alternative dewatering systems and recommend the optimum system(s) for each area of the city against the governing parameters, with special attention to eastern Riyadh.

Manage all available dewatering systems in one editable GIS map with unified symbols and data appearance, extendable for new projects.

Evaluate existing dewatering projects’ efficiency in water-table control to inform the recommended approach.

1.3 Submittal Review & Urgent Designs

Review and approve technical submittals sent by other parties (consultants, investors), including design changes on running construction projects.

Deliver small and medium detailed designs of dewatering systems for areas requiring urgent improvement, including site verification where needed.

Investigate water-rise complaints, determine the cause, and propose practical solutions where groundwater rise is confirmed.

1.4 Hydraulic Modeling Support & Integration

Provide 1D dewatering pipe/canal and 2D overland-flow hydraulic representation to support design decisions and the interface with the numerical groundwater model.

Apply the value-engineering concept across design activities so investment targets the greatest benefit per unit cost.

Apply the value-engineering concept across design activities so investment targets the greatest benefit per unit cost.

Task C Deliverables the Role Leads

The Hydraulics Engineer leads the Task C deliverables across the program term (*urgent packages are due three months after each client request):

Task C Deliverable / Content the Role Leads

Task Inception Report / Methodology, assessment of current design methodology, action plan. Term M2

Tender-Document Templates & Updated Package / Updated design criteria, specifications and reusable tender templates. Term M8

Urgent Tender Package(s) / Complete detailed-design tender packages for urgent areas, on client request. Term M+3*

Task Completion Report / User manual, training, package evaluation and closeout. Term M12

Minimum Qualifications & Experience

A minimum of fifteen (15) years of professional experience in hydraulic and dewatering-system design is required, consistent with the program’s Category B requirement (15+ years, degree and accredited professional membership). Candidates below this threshold will not be considered.

15+ years in hydraulic design of dewatering, drainage and groundwater-lowering systems (slotted-pipe/subsurface drains, wellpoint systems, canals and culverts).

Degree (Master’s preferred) in civil, water-resources, hydraulic or environmental engineering, with accredited professional membership.

Strong command of design criteria, methodology and specifications for dewatering and drainage infrastructure, and of tender-document preparation.

Proven ability to analyze alternative dewatering systems and recommend the optimum solution per area against governing parameters.

Experience reviewing and approving third-party technical submittals and design changes on running construction projects.

Hydraulic modeling competence (1D pipe/canal/wadi flow, 2D overland/rainfall-runoff) to support design decisions and the numerical model interface.

Familiarity with the special conditions of eastern Riyadh and with value-engineering of infrastructure solutions.
