Saudi Arabia's King Salaman Garden NWC Project: A Benchmark for Urban Water Infrastructure

The King Salaman Garden project stands as a prominent urban development initiative in Riyadh, aligned with Saudi Arabia's vision for sustainable city planning and efficient water resource management. As a key project under the National Water Company (NWC)— Saudi Arabia's government-owned water utility tasked with delivering water and wastewater services to international standards  — it plays a vital role in enhancing Riyadh's urban landscape while adhering to the kingdom's strict water conservation and infrastructure efficiency regulations.

Commissioned by Riyadh Municipality, the project's water system infrastructure requires robust, reliable fluid control solutions to support its diverse applications— including irrigation, landscape water supply, and auxiliary water management. These systems must comply with Saudi Arabia's national water efficiency and energy conservation standards, which mandate valves with exceptional sealing performance, durability, and low operational energy consumption.

The project's operational requirements impose specific technical demands on valve products:

- High-pressure stability: Valves must withstand PN16 pressure ratings to ensure safe operation in Riyadh's water distribution networks;

- Backflow prevention: Critical for protecting water quality and system integrity, requiring check valves with fast-acting, leak-tight closure;

- Durability in arid conditions: Saudi Arabia's harsh desert climate (extreme temperatures, sand exposure) demands corrosion-resistant, weatherproof valve construction;

- Compliance with local standards: Adherence to Saudi building codes and NWC's water infrastructure specifications (aligned with international standards such as SBC 701)  for seamless integration and regulatory approval.

As a first-time supplier to NWC, WEIZIDOM underwent rigorous technical evaluation to demonstrate product compliance, performance reliability, and alignment with the project's specific needs. The successful selection reflects WEIZIDOM's ability to meet Saudi Arabia's high infrastructure standards and deliver solutions tailored to the region's unique operating conditions.
