water supply interruption & pump maintenance

some report on the water supply interruption incident & immediate measure to counter it.....

we were alerted by residents from blk k on Wednesday afternoon abt the low water pressure, and subsequently no supply at all at abt 6.45pm.

2 MC members went to the blk k roof top to checked on the water tanks, to their shocking, all the 4 water tanks were without any water, so they went on to check the main tank at the ground floor, the main tank is where the PBA supplied water be stored, before be sent to the 4 water tanks at roof top.

They found the water level at the main tank is full, which means the pumps didn't do the job of pumping the water to refill the roof top tank, and this condition should be at least 2 days already because it will take more than 2 days for blk k residents to use up all the water in the roof top water tank.

and it's true enough that, it was short circuit & the trip caused no electrical supply to the control panel which resulted pump not running, so we quickly reset the MCB at the switch room, and the pumps run immediately, water supply back to normal at 7.20pm, a bit yellowish, but quality of water improved over times & it's good at midnight hours.

in order to prevent the same thing happen in the future, we called few pumps experts to come in on 13/9/14 (Saturday) morning to check, assess all the water pumps, control panels, float sensors, valves and other related essential components, to produce a report to us which component need to replace or repair now, and even a long term maintenance contract to check & service the mentioned equipment on the regular basis, we hope can finalize the matter in the MC meeting this week & seal the deal, so that the pump vendor can start help to monitor & service our pumps & it's related equipment as early as this month.

thanks.
