However, according to officials, the DRDO did not initiate any action on their plea, prompting the LAWDA to approach foreign firms.
A senior official of LAWDA, Khurshid Maqdoomi, said the department wrote to the DRDO in June 2011 after learning about the vast expertise of the organisation in the subject.
The LAWDA most sincerely invites the co- operation from DRDO in this regard.
LAWDA argues that at Doldam houseboats will be provided with all the facilities, including sewage treatment plants.
Harri Tainio, an Italy based engineer who has come to Srinagar for helping in assembling and testing of the machine with the LAWDA officials, is confident that the machine would be successful in cleaning the Lake.
Presently, the LAWDA has two dredgers and four harvesters.
