HYDROAIR TECTONICS (SPD) PVT. LTD was established in the year 1987 to provide Marine and Ocean engineering services to Indian industries. The year 1991 saw the opening up of the till then conservative Indian industrial sector. New economic and industrial policies were formulated and the nation embarked upon a journey towards liberalization, industrialization and progress. High technology industries appeared on the Indian industrial zone. Then the need was felt for effective environmental protection and preservation systems to supplement this journey towards progress. To support this national cause, Hydroair expanded its sphere of activities to include the state-of-art, high technology marine & ocean engineering services to Indian industry. And thus, today, Hydroair is a fully integrated corporate dedicated to the cause of nations progress.
Hydroair is steered by its Director Mr. K. P. Vijayshanker, internationally renowned technocrat supported by a team of engineers in the field of marine and ocean engineering. Right from inception, Hydroair firmly believed in and adhered to Excellence, Innovation and Commitment. Excellence in Performance, Innovation of Technology, Commitment to Quality. These are the guiding principles that propel Hydroair towards Engineering Nations Progress. Hydroair has come a long way through all these years and successfully laid many dozens of offshore pipelines all over the Indian coastlines.

Hydroair’s expertise and wide experience with 100% success rating in the fields under reference thus remain unmatched as yet in the country compared to any other organisation or MNCs operating in India.
Hydroair enjoys turnkey assignments right from concept to design to installation & commissioning with performance guarantee. No doubt, many major industrial units in the country consider us as the “Numero-Uno” in design and execution of marine outfalls as a total package, among the contemporaries. Our future vision is to conquer the foreign seas and emerge as global competitors in the field of Outfall and Intake pipelines.

We “HYDROAIR” possess unmatched experience in execution of marine outfalls with multi-port diffusers/Sea-water intake pipelines on turnkey basis from concept to commissioning with all allied civil, mechanical, electrical, instrumentation and marine engineering works. Our Directors have had the privilege of handling:


  • Maximum number of successful marine outfalls/submarine pipelines in open sea/estuaries in the western and eastern coasts of India.
  • First sea water intake scheme in the country with shore pumping system successfully.
  • Longest effluent disposal pipeline in sea with diffuser – 6.0 kms offshore in Gulf of Cambay.
  • First large diameter HDPE submarine pipeline laid in the country (900 mm OD) in 1992.
  • Largest single outfall of industrial effluent – 36 MLD flow rate – with staggered diffusers.
