Operation & Maintenance: The commissioning, running, and maintaining of the scheme for five years encompasses expenses related to consumables, establishment, operation, and maintenance repairs. Essential consumables such as alum, chlorine, and lime are vital for water treatment processes, ensuring the distribution of safe and clean water. Establishment costs include various operational needs, such as staff salaries, employment of operators and valve men, and other administrative and logistical expenses required for the seamless operation of the water supply infrastructure. Regular inspections, servicing of mechanical components, and replacing worn-out parts are necessary to prevent system failures and ensure continuous operation. This involves routine maintenance activities like cleaning and repairing pipelines, pumps, and valves, as well as addressing unforeseen damages. Effective repairs and maintenance are crucial to minimize downtime, reduce the risk of major breakdowns, and extend the lifespan of the water supply infrastructure and any other works. Upon completion of the five-year period, the scheme will be handed over to the Local Body/Municipal Board as directed by the Engineer-in-charge. (EXCLUDING ELECTRICAL CHARGES)
