11 Mechanization of Sewer System & Preventive Maintenance In order to prevent entry of manual labourers in the sewer system the CMWSS Board has progressively mechanizing the removal of silts and sewer obstruction. CMWSS Board is presently engaging the following machineries for sewer system maintenance 1. Desilting Machines : 234 Nos 2. Jet Rodding Machines : 114 Nos 3. Jetting cum Suction Machines : 30 Nos 4. Super Sucker Machines : 43 Nos All Depots having sewer system has been provided with sewer cleaning Equipments. Metrowater has programmed for Preventive Maintenance of existing sewer system in Chennai City& this has been categorized once in a month, 3 months, 6 months & 12 months so as to avoid break down maintenance. The No. of sewer overflow complaints have been reduced considerably after 21 implementing this Preventive Maintenance in chronic areas.
