The Span Story.

Founded by Mr. Nandkishor Gaidhani, the Span Group is snowballing with revenues exceeding INR 10 crore through our various activities in water and wastewater treatment. Span Engineers laid the foundation stone of the group in 1999. In 2007, we restructured into a private limited company – Span Hydrotech Private Limited – to integrate our processes. It is always our aim to offer an optimal experience for clients using our water treatment and chemical solutions. We prioritize innovative designs and practical implementation of our solutions. We follow a balanced philosophy towards business, which has helped us create healthy, long-lasting business relations with our clients and employees.
