Education

Born in 1874 in Galle, as the eldest son of master craftsman Mudaliyar Don Juan Wimalasurendra, He received his education at Ananda College, Colombo and joined the Ceylon Technical College in 1893, while working as an apprentice at the Government Factory. He graduated in Civil Engineering from the Ceylon Technical College and gain Associate Membership of the Institution of Civil Engineers (AMICE). In 1912, Wimalasurendra attended Faraday House in Stevenage, England specializing in electrical engineering and gaining the Faraday House Diploma in seven months, also gaining Associate Membership of the Institution of Electrical Engineers in Britain.

Engineer Career

In 1896 he joined the Public Works Department as a field overseer, and was promoted to an Inspector within four years. Having become a Junior Assistant Engineer by 1900, he worked on building the concentration camp in Diyatalawa for Boer prisoners captured in the Second Boer War; in 1901 he conducted a survey on mineral deposits in the Kelani Valley. Having had his initial proposals on hydro power ignored by the Engineering Association of Ceylon he constructed the first small hydro power station in Ceylon, at Blackpool, between Nanu Oya and Nuwara Eliya, to supply electricity to the town of Nuwara Eliya. In 1918 he submitted a paper to the Engineering Association of Ceylon titled "Economics of Hydro Power Utilization in Ceylon"; in it he proposed the possibility of hydro power from Maskelioya and Kehelgamuoya, capable of lighting 100,000 lamps (114.5 MW). He also introduced the concept of developing a national grid. Only in 1923 did the colonial government undertake the development of hydro power in Ceylon, but Wimalasurendra was left out of the project and left the country on leave to England. He returned only on the request of the Colonial Secretary. In 1926 he was appointed Chief Engineer of the Public Works Department (PWD). Soon after he began the separation of the electrical section of the PWD. To this end under his direction the government took over the Colombo Electric Scheme (established in 1918) to supply power to the Colombo city and the tramways run by Bousteads Brothers Ltd. He became the Deputy Director of the newly formed Department of Government Electrical Undertakings (DGEU) in 1927, and established the first thermal power station in 1929, Stanley Power House. Having his projects undermined, he retired early from public service in 1929
