Dear CE,
Due to swimming pool problems which the water change to green color and dirty as Mr. Marco comment in previous meeting. It is because the rain which have high Acid and cause to lichen in the water. First, to solve these problem the Building management would like to purchase the Chemical to apply to the swimming pool (see attach files) and we would like to purchase alum in addition for 1 bag (15 kg. 400 THB. include transportation) to make the water precipitate.
The chemical include; 1. Chlorine, used to purify water and as a bleaching agent and disinfectant.
2. Filter powder, the white powder special substance in the water
3. Soft Salt, the acid use when the water have high pH
Second, due to the Surge tank that use to circulate the water into the swimming pool never open so we would like to open it to check the equipment in side the tank.
Therefore, the Building Management would like to request to approve to purchase the Chemical as total cost 23,219.00 THB including 7% VAT., alum for 1 bag (15 kg./ 400 THB.) and approve to open the Surge tank which will open at the same time with open the waste water tank as total cost 5,150.00 THB.
