Company History
The company's history began in 1985 with the establishment of River Wisawapan Limited Partnership (ห้างหุ้นส่วนจำกัด ริเวอร์ วิศวภัณฑ์), which operated as a construction contractor. We have consistently provided services with dedication and offered the best to all our customers, which led to increasing consumer trust.
Subsequently, the business expanded into the engineering sector under the new name, River Engineering Co., Ltd. (บริษัท ริเวอร์เอนจิเนียริ่ง จำกัด), focusing primarily on flood protection engineering and environmental preservation. We continue to maintain the same dedication and commitment to providing the best to our customers, while also serving as a distributor for quality international products. In addition, the company has earned the trust of both government and private sectors to undertake the design, manufacturing, and installation of large-scale products, such as pumping machines in various projects.

For over 40 years of long-standing experience in environmental engineering, construction service, drainage system management, heavy machinery, diesel engine, power tools, and electrical system installation, River Engineering has been entrusted by both public and private sectors as being the leading provider of relatively large-scale irrigation systems and wastewater management activities in Thailand. Our clients include Bangkok Metropolitan Administration, Royal Irrigation Department, State Railway of Thailand, Electricity Generating Authority of Thailand and other private corporations.
One of our most delightful commitments was to engage in Kaem Ling Project, the Royal Initiative Project Under the Royal Patronage of His Majesty the King Bhumibol Adulyadej, providing insights in flood protection measures and flood crisis management to several parts of Bangkok and other suburban areas.
We believe successful results are achieved through the combination of every individual effort in River Engineering and the reliance placed upon our products and services by all valued customers. We are committed to continuously improving the quality of our products and services, the responsiveness to all client enquiries, the supply of cutting-edge technology including the broader range of products, the excellent learning opportunities for our employees and above of all, to be an integral part of social and environmentally sustainable developments.
Lastly, as being a CEO of River Engineering, I would like to forward my gratitude and appreciation for the effort and dedication of our team and every individual as well as the support from all customers. My team and I are forward-looking to serve you again in the near future.
