Walk me through your water planning career.
I've been a planning engineer for eight years, four in Oman. Started in water network planning at an Indian utility consultancy, transitioned to Oman utility work, and for the past three years I've been planning engineer for water distribution at an Omani water utility EPC. My remit: water distribution project planning, hydraulic modelling input, GIS integration, schedule and resource planning. Primavera P6 plus water-specific credentials.

Tell me about a major water project.
Last year I planned a major distribution network extension: 80km of new mains across multiple wilayats. Twelve months of planning and execution. Phasing minimised customer disruption. Project completed on schedule. Water network projects need careful customer impact management.
Water delivery.
Describe a customer impact issue.
Network shutdown for tie-in affected more customers than planned. Investigation: hydraulic model hadn't captured all dependencies. Apologised to affected customers, completed tie-in efficiently, restored service ahead of revised commitment. Updated hydraulic model for future planning. Customer impact in utilities is highly visible.
Customer impact handling.
Tell me about working with operations.
Water operations runs the network 24/7. New projects affect their work. Engagement early in planning. Operations input shapes phasing and shutdown windows. The relationship matters for sustained partnership.
Operations engagement.

Technical & role-specific
Questions that test your specific skills for this role.
Walk me through water network planning.
Demand forecast per zone. Hydraulic modelling for sizing and configuration. Material selection per local conditions. Construction methodology. Customer impact assessment for shutdowns. Phasing to minimise impact. Construction schedule. Water network planning is engineering applied to infrastructure.
Network planning depth.
Describe hydraulic modelling integration.
Hydraulic model represents the network. Updates with new infrastructure. Used for sizing decisions, pressure planning, water quality (residual chlorine, age). Calibration with field data. Without hydraulic modelling, planning is guesswork; with it, engineering precision.
Hydraulic modelling.
How do you handle phasing?
Phasing minimises customer disruption and construction complexity. Tie-in sequencing planned. Shutdown windows scheduled. Customer communication coordinated. Alternative supply during shutdown where critical. Phasing is engineering plus customer-experience design.

Situational
Hypothetical scenarios designed to test your judgement and approach.
A project change affects schedule significantly. What do you do?
Honest impact assessment. Engage stakeholders: operations on shutdown implications, customers on service impact, leadership on commercial implications. Updated plan with realistic timeline. Document decision. Changes that affect customers need transparent handling.

Closing
The final stretch. Often where deals are won or lost.
What are your salary expectations?
For a senior planning engineer role on water distribution at an Omani utility EPC I'd target OMR 1,800 to 2,400 total package depending on project scope. Utility experience plus planning specialism commands a premium. I'd expect annual bonus and certification budget. I'm on 60 days' notice. Beyond pay I'd value the utility's modernisation programme.
