Air-tech machines for preventive sewer cleaning

July 13, 2016 12:00 am | Updated 05:39 am IST - HYDERABAD:

The Hyderabad Metropolitan Water Supply & Sewerage Board (HMWSSB) has decided to utilise the air-tech machines for preventive sewer cleaning during the nights in different divisions for cleaning the sub-mains sewers on a continuous basis so that the free flow takes place on the lateral sewers.

This practice is already followed by other Water Boards, hence the same is to be started here too for effective maintenance of the sewer lines during the monsoon, according to MD M. Dana Kishore on Tuesday after a meeting with his top officials.

The Water Board will also be engaging 150 mini air-tech machines with 25 among them to be deployed for attending chokages and the balance of 125 will be for ‘preventive sewer maintenance’ along with 47 bigger air-tech machines.

While 47 air-tech machines are working on a hire basis, 11 vehicles are owned by the Board and all the 58 vehicles are working for attending chokages and overflows during day time.

Repairs to manholes

Mr. Kishore also promised to take up manhole repairs on a war footing basis to bring on level with the road surface.

Safety guards are to be erected as also caution boards to at the work sites. He also said that the AVTS (Automatic Vehicle Tracking System) would be started shortly on a pilot basis in 390 vehicles including free water tankers and air-tech machines.

He sought preparation of Standard Operating Procedures (SOPs) for maintenance of chlorination plants, regular cleaning of reservoirs, inspections to be undertaken by the linemen for all sewerage inspectors and managers of the operations and maintenance wing.

Further, the senior officials were told to install ATWs (Any Time Water kiosks) at various places, expedite fixing of CCTV cameras in all major work sites and service reservoirs.

ED M. Satyanarayana, Directors (Tech) P.S. Suryanarayana, (Ops) G. Rameshwara Rao, (Revenue) D. Sridhar Babu, (P&A) Azmeera Krishna, and others participated.
