2026-09-112026 年 9 月 1 日, Saudi National Water Company (NWC) officially signed a USD 3.47 亿 (SAR 13 亿) contract with a China-Saudi consortium at its Riyadh headquarters. Led by China's Jiangsu United Water Technology, with Saudi Armada Holding and UAE-based Prosus Holding as shareholders, the project will upgrade 9 sewage treatment plants in Hail, Qassim, Al-Jouf, and the Northern Borders Province in northern Saudi Arabia, and provide 15 年 full-cycle operation and maintenance, with a total design treatment capacity of 33.7 万 m³/d. It is a landmark contract for a Chinese water company to enter Saudi Arabia's high-end water operation market with a "retrofit + 15 年 operation" model.
I. Contract Overview: USD 3.47 亿 + 9 Plants + 15 年 O&M
According to MEED and Wedoany, Saudi National Water Company (NWC) and the China-Saudi consortium officially signed the LTOM (Long-Term Operation and Maintenance) Package 10 contract at NWC headquarters in Riyadh, the capital of Saudi Arabia. The contract amount is USD 3.47 亿 (SAR 13 亿), covering 4 provinces in northern Saudi Arabia (Hail, Qassim, Al-Jouf, and the Northern Borders Province) with a total of 9 sewage treatment plants and a total design treatment capacity of 337 000 m³/d (approximately 33.7 万 m³/d).
The contract term structure includes:
- Initial retrofit period 3 年 — comprehensive retrofit and upgrade of the processes, equipment, and pipe networks of 9 sewage treatment plants, plus the addition of sludge drying facilities;
- Long-term O&M period 12 年 (total cycle of 15 年) — full-cycle operation and maintenance to ensure that effluent, sludge, and environmental performance fully comply with Saudi national standards;
- Treatment unit price — 0.69 SR/m³ (approximately USD 0.18 /m³), consisting of three parts: "capacity revenue + treatment volume revenue + standby revenue."
II. Consortium Structure: Led by Jiangsu United Water Technology + Saudi Local Partner + UAE Capital
The project consortium consists of three parties, a typical "Chinese technology + Saudi local execution + Gulf capital" tripartite collaboration model:
- Jiangsu United Water Technology — the consortium leader, responsible for overall design, investment, operation, and part of the construction; leveraging years of Chinese water operation experience, it will introduce China's mature water management system into the Saudi market;
- Saudi Armada Holding — responsible for construction, equipment import customs clearance, and local business coordination;
- UAE-based Prosus Holding — financial investor, providing project financing support.
The project company is 100%% held by the consortium, and NWC pays service fees to the project company through a three-part payment mechanism of "capacity + treatment volume + standby," ensuring stable and predictable cash flow.
III. Strategic Significance: Entering Saudi Arabia's "Vision 2030" Water Sector
Saudi Arabia is one of the most water-scarce countries in the world, with average annual precipitation of less than 100 mm. Under the framework of "Vision 2030" and the "National Water Strategy 2030," Saudi Arabia continues to increase investment in water infrastructure and introduces international professional water operators through NWC's global tenders. The strategic significance of Jiangsu United Water Technology's signing this time includes:
- A landmark leap from "winning the bid" to "implementation" — The company received the Letter of Acceptance in early 2026 年, and the signing of the 9 月 1 日 contract marked the project's official transition from the commercial stage to the execution stage;
- A model for "Belt and Road" green water cooperation — Chinese water companies are participating in Saudi water operations through technology service export, bringing the mature practices of China's water industry into the Middle East market;
- A window for 15 年 long-cycle service going global — The 15 年 contract term means 15 年 stable service fees, equipment replacement, and smart upgrade demand, making it the best long-term partnership model for Chinese water equipment going global.
IV. Follow-up Project Pipeline: LTOM 11/12/14 Successive Tendering
Saudi NWC's LTOM program is a series of long-cycle O&M contract packages covering all of Saudi Arabia. Those already signed and in progress include:
- LTOM Package 10 (signed) — 9 plants, totaling 33.7 万 m³/d, 3.47 亿 USD;
- LTOM Package 11 (to be signed soon) — The same consortium is expected to sign within the coming months, with a total treatment capacity of approximately 44 万 m³/d;
- LTOM Package 12 (under bid evaluation) — North Western B Cluster, covering 7 STPs, totaling approximately 16.2 万 m³/d;
- LTOM Package 14 (under tendering) — Eastern A Cluster, covering 6 STPs, with the Al-Jarodia plant expansion of 3 万 m³/d, total investment of 1.8 亿 USD, bid closing on 9 月 30 日.
V. Impact on TIANYI TECH's Business in Saudi Arabia and the Middle East
Jiangsu United Water's winning of LTOM Package 10 is a landmark event for Chinese water companies entering Saudi Arabia's high-end operations market, and has direct demonstration value for TIANYI TECH's water equipment going global in Saudi Arabia and the Middle East:
- Membrane pretreatment and advanced treatment equipment going global — The renovation and upgrading of 9 plants will drive procurement of membrane modules, MBR, RO/NF, UV disinfection, dosing systems and other equipment, and the company has the capability to engage directly;
- Sludge Drying and resource recovery equipment — The contract explicitly identifies "adding Sludge Drying facilities" as a renovation priority. The company's low-temperature Sludge Drying, paddle-type drying, solar drying greenhouse and other equipment can be introduced as subcontracting solutions;
- Consumables supply chain required for long-cycle O&M — The 15 年 O&M cycle will continuously generate procurement demand for membrane modules, dosing chemicals, spare parts, instruments and meters and other consumables. The company can enter Saudi Arabia's qualified supplier list as a subcontracting supplier;
- Smart Water O&M platform — Unified O&M of 9 plants sets uniform standards for SCADA, energy management, online water quality monitoring, and performance benchmarking systems. The company can cooperate with domestic industrial internet vendors to package and export a "China Water Brain".
