Delhi minister Gopal Rai, who heads the department, felicitated them at a function at the Delhi Secretariat.
He said the performance was rated as per the appreciation certificate issued by the area MLAs for all development projects carried under the jurisdiction of the officers.
"A system has been adopted in the department wherein MLAs give endorsement letters against quality of work done by them in their area," Rai said, adding that a special committee then evaluates the work accordingly.
Besides maintenance of major drains, the Flood and Irrigation Department, executes all development works in the rural areas, unauthorised colonies and projects under MLA LAD funds.
