AE reported that the existing submersible pumps used at various pump houses are old, and frequent repair has to be done to ensure proper distribution of water. Due to these repeated maintenance, there is a huge revenue loss to the Kerala water authority. Also sincethere is no standby motor at times of maintenance,serious water shortage is being faced by consumers. Hence, due to the necessity new pump setEstimates were submitted for approvalNB: Pump rate incorporated vide Proceedings of MD, No KWA/HO/SP/333/2011/Pumps dated 20/12/2011 |
