Remarks 1. Mar 2016 had dregdging sediment in front of Mor Mui weir which place inside Klong Nam Dang canal. So it needed to stop divert water from Prasae reservoir for a whole month and adjust the water diversion plan from 8 MCM to 9 or 9.3 MCM per month started from Apr – Sep 2016 2. On Oct – Dec 2016 Plan to divert water can be change depend on water situation 3. PS – NPL pipe system is start testing on 3 Nov and found the crack on pipe. So we’ve to stop testing pipe and fix it. Then we will start commissioning test again around middle of NOV.
