Operation in general refers to effective running of system routinely and Maintenance in general refers to upkeep of system by planned, preventive or corrective maintenance, repairs etc. Effective and efficient operation and maintenance of water supply system results into better water supply service delivery as per acceptable norms of quantity, required quality and at required pressure with reliable continuity. We offer distinctive O&M services for entire water supply network with required qualified & competent resources, proper asset management programs as per manufacturer’s recommended guidelines for equipments’ checks in time bound manner. This mainly include well defined O&M Plan involving routine tasks, specific tasks at regular intervals including inspection of system (daily, weekly, quarterly, annually etc.), checklists, log-sheets for operation, supervision & maintenance, inventory management, with proper tools & plants, upkeep of records, history etc.
Water Network Management: As water utilities are under increasing pressure to improve the quality of service while reducing leakage, it is becoming critical to better understand and control the main factors affecting failures. The hydraulic instabilities and transient events affect asset failures. The following network operations may cause transients:
Boundary Valve Operations, Opening or closing the connections between neighbouring DMAs will cause a flow of water unless both DMAs are at the same pressure, Filling of Pipes after replacement or drainage for maintenance, Flushing stale water and sediment out of dead-ends and low points in the network, Starting and stopping of Pump as well as turbulence caused by imperfect running, Operation of Pressure Reducing Valves in the network, these may change or create transients, Valve Operations-closing off a section of network into which there is a flow or opening up a section at a different pressure, Some bulk users, Industrial Users may cause transients when they draw or stop water, Bursts in pipeline also cause transients due to increase in consumption at a point in the network.
It has been proved that a 10% reduction in pressure can deliver a 10% leak reduction and 14% burst rate reduction. The ultimate objective is to operate a water supply system as close as possible to steady-state hydraulic conditions. Consequently, the monitoring and analysis of the dynamic hydraulic conditions is an important consideration of water supply systems. Rapid changes in the flow significantly affect the disinfectant decay and residual due to resuspension of sediments, scouring of biofilms on the internal of the pipes. Controlling the pressure in the water network is key to avoid bursts, reduce water leakages, preserve water resources, and decrease operating costs. Calm Network is a proactive approach targeting smart pressure control within drinking water networks.
