SUMMARY

OF THE WATER VOLUME, AND PROGRESS OF WATER SHORTAGE

PREVENTION AND MITIGATION MEASURES IN RAYONG AND PROVINCES FOR 2015-16

CHONBURI

 On February 2nd 2015 the combined water volume in the 3 reservoirs is = 188.58 MCM. (68.5%) • Decrease since yesterday= -1.05 MCM. •

Water diversion through tunnel from the KlongYai res. to NongPlaLai res. presently stopped due to Klong Yai Res. level being lower than Nongplalai Res.

Water transfer from Prasae Reservoir to Klongyai Reservoir  Currently, pumping stopped for pipeline construction



The Royal Irrigation Department has temporarily raised the spillway level at Klongyai and Prasae Reservoirs by 0.50m

RID and East Water

Pumps and motors are purchased, with installation and permit request expected to take 4 months. Pumping should start in June 2015.

2. Supporting measures 2.1 Pumping sideflow from the Rayong River back to Nongplalai Reservoir using RID’s Lahanyai pump station
