| 1 | Design, Supply, Installation, testing and Commissioning of WQM (Water Quality Monitoring System) with real time online monitoring all the specified parameters as per BSI std for drinking water and have a check on the given parameters. WQM should be a skid mounted system comprising of SS storage Sampling tank of 60 Ltr Capacity, circulation pump, Control panel, interconnecting piping with all valves & Fittings. System should be installed in parallel to the existing water supply line, it should take bleed from the water supply line and should reconnect to same line. Sampling tank should have all the sensors attached to it to monitor the real time parameters. The sensors should be compatible to the Local BMS. The entire system of pump, tank and fittings shall be mounted on base plate and shall have structure frame to strengthen/balance the entire skid. The supplier shall comply all the specification. The system should be ISO 9001:2015 and CE Marked. The system shall be equipped with following feature and specification as under. |
