Water Sector
Integrated design and advisory for water transmission, distribution and non-revenue water programmes across the Kingdom.
The opportunity.
Saudi Arabia's water sector is undergoing one of the most significant transformation programmes in its history. Ageing transmission networks, rapid urban growth and the Kingdom's water-security agenda under Vision 2030 are driving unprecedented investment in water infrastructure — from major desalination feed mains to last-mile distribution upgrades and smart metering rollouts.
WPEC provides independent, client-side engineering consultancy at every stage of the water project lifecycle. We work alongside national utilities, regional municipalities and private developers to deliver technically rigorous, regulation-compliant and operationally sustainable water systems.

Our methodology.
Data Collection & Audit
System-wide data gathering — flow, pressure, demand, asset condition — to establish a reliable baseline before any modelling or design work begins.
Hydraulic Modelling
Calibrated network models built in EPANET or WaterGEMS to test design options, forecast future demand and identify system vulnerabilities.
Concept & Feasibility
Multiple design alternatives evaluated on technical performance, capital cost, operability and whole-life cost to identify the optimum solution.
Detailed Design
Full multi-discipline design package — hydraulic, civil, mechanical, electrical and instrumentation — to international codes and Saudi standards.
Procurement Support
Tender documentation, bid evaluation, contractor pre-qualification and technical clarification support.
Construction & Commissioning
On-site supervision, hold-point inspections, performance testing and handover to client operations.
