H RESULT OF SOIL INVESTIGATION

GEOLOGY OF YANGON AREA The geology of Yangon area was classified into the following geological units: (a) Quaternary deposits - 4. Upper Delta Alluvium, Pleistocene and Recent - 3. Lower Delta Alluvium, Pleistocene (b) Tertiary deposits - 2. Irrawaddian Series, Pliocene - 1. Pegu Series, Oligocene-Miocene The regional geological study has been made in an area which includes ridges and deltaic lands lying south of the Bago Yoma. This area is in a north-south trending synclinal basin containing a thick Tertiary - Quaternary deposits. The Tertiary deposits are strongly folded into narrow en-echelon anticlinal folds such as the ridge, which is trending south towards the Gulf of Martaban. The rocks of the Tertiary age contain well-consolidated marine sandstone and shales of the Pegu Group and semi-consolidated, continental deltaic and marginal marine (?) deposits of the Irrawaddy Formation. The synclinal valley west of the Yangon anticlinal ridge is filled with unconsolidated water laid deposit of Quaternary age. These form a wedge shaped alluvial accumulation ranging in thickness from a few meter near the ridge about 60 to 90 meter in the valley. These sediments include clays, silts, sands and predominantly fine to coarse gravels. The Boreholes Location Points with the geological Map of Yangon area is presented as following.

4. GEOLOGY OF YANGON AREA

The geology of Yangon area was classified into the following geological units: (a) Quaternary deposits

- 4. Upper Delta Alluvium, Pleistocene and Recent

- 3. Lo we r De lta Alluvium, Ple isto c e ne

(b) Tertiary deposits

- 2. Irra waddian Se rie s , Plio c e ne

- 1. Pegu Series, Oligocene-Miocene

The regional geological study has been made in an area which includes ridges and deltaic lands lying so uth of the Bago Yoma. This area is in a north-so uth tre nding synclinal basin containing a thick Tertiary - Quaternary deposits. Geologic succession of the Yangon area is shown in table.

I REVIEW FOR PRELIMINARY DESIGN OF LAGUNBYIN WTP

A series of discussions on design of Lagunbyin water treatment plant have been made with YCDC in the design review stage and revisions were made on the design by JICA Study Team.

1. Intake Canal Intake canal was shifted from irrigation canal to existing natural creek by determination in discussion with YCDC and MOAI in October, 2013.

2. Designed Ground Level Designed water levels are calculated by hydraulic calculation in the review. In order to apply existing foundation pillars as much as possible, Bottoms of sedimentation basins and filters are set as nearly existing ground level (+2.926m =+9.6').

3. Existing Foundation Pillars Arrangement and size of the facilities which can apply existing foundation pillars under construction by YCDC are adopted. The location of sedimentation basins, the size of filters, and the size of clear water reservoir are changed by the review.

4. Pre-sedimentation Pond Precipitation tests proved that turbidity decreases to 65% by settling time of approximately 12 hours. In order to take raw water of low turbidity, pre-sedimentation pond with retention time of 12 hours above is designed by the review. And since much sand settles on the bottom of the pond, the pond has 1m storage space toward the bottom from LWL.

5. Intake Pump The Number of intake pump proposed by F/S was 4 units (3 duty + 2 stand-by). On the other hand, YCDC have proposed 6 units (4 duty + 2 stand-by).

6. Dividing Well On the YCDC design, raw water of different quality is directly led to each sedimentation basin from each intake pump. Since PAC dosing rate differs by each basin on such a design, control of aluminum injection is complicated. In order to supply raw water of the same quality to sedimentation basins, dividing well is generally installed in Japan. Dividing well/ tower is designed by cylindrical shape in order to distribute raw water equally to 4 sedimentation basins, and weirs are installed in the tower.

7. Iron Removal According to water quality tests, iron of 0.3 mg/L (beyond the standard value) has been detected. In order to secure contact time of raw water with air, weirs in dividing well are set up highly.

I-1 The Project for the Improvement of Water Supply, Sewerage and Drainage System in Yangon City Vol IV Water Supply System Feasibility Study, Appendix

8. PAC Dosing Facility PAC currently used by Nyaunghnapin WTP is adopted from the result of jar tests by YCDC. According to YCDC, coagulating effect of PAC is better than aluminum sulfate. Hydraulic jump method currently used by Nyaunghnapin WTP is adopted as coagulant mixing.

9. Flocculation Basin Horizontal and vertical zigzag flow method as Nyaunghnapin WTP with same mixing for flocculation is adopted. The widths of channels are set up by capacity calculation on the review in order that raw water and PAC might mix completely. And inlet flow to flocculation basins and sedimentation basins is changed into underflow in order that floc might not break.

10. Sludge Discharge Method of Sedimentation Basin As sludge discharge method on the design of F/S, the bottoms of sedimentation basins have a slope, and have several hoppers. Since this design had insufficient sludge discharge, YCDC suggested that the bottoms should have more hoppers.

11. Tube Settler in Sedimentation Basin The installation area of tube settler on the YCDC design is a few one. Based on the design standard of Japan, installation area is reconsidered on the review.

12. The number of Filter The number of filters on the YCDC design is 24 basins x 2 trains. According to train of sedimentation basin, the number is changed into 6 basins x 4 trains on the review.

13. Flow Rate of Filter On the YCDC design, flow rate is 240 m/day of the upper limit in two-layer filtration. In order to take stabilized raw water quality, flow rate is limited to maximum 150 m/day on the review.

14. Backwashing Method of Filter Nyaunghnapin WTP has backwashing with surface washing for filters. YCDC suggested that the maintenance of above method takes time and effort, and many mud balls have been produced on the surface of filters. YCDC proposed that backwashing adopted air washing for the new WTP. And YCDC proposed that control valves are installed within backwashing pumps and air blowers.

15. Under Drain System of Filter YCDC proposed that strainer type which can be manufactured in Myanmar is applied to under drain system. This method is already adopted in Phase2 of Nyaunghnapin WTP. The processing effect is not so good although traditional Tee Pee type (Made in Red Indian) is adopted in Phase1.

I-2 The Project for the Improvement of Water Supply, Sewerage and Drainage System in Yangon City Vol IV Water Supply System Feasibility Study, Appendix

16. Inlet and Outlet Valves of Filter In order to control flow by a motor, handling spaces are provided for periphery of weirs and valves on the review.

17. Clear Water Reservoir Capacity of clear water reservoir is little on YCDC design. The capacity of 1 hour above is designed on the review, and the number of reservoirs is set to 2 trains.

18. Chlorination Facility About chlorination facility, YCDC proposed that Electrolyzer (On-site generation of liquid hypochlorite) installed in existing Yegu pumping station is suitable from a viewpoint of finances and procurement. YCDC can procure easily the salt which is material of hypochlorite generated by Electrolyzer. According to YCDC, the viewpoint of cost to procurement is hard for imported products, such as Gas cylinder, Liquid chlorine and Powder. Since a rough maintenance for Electrolyzer might cause explosion, the Study Team advised keeping up sufficient maintenance.

19. Sludge Treatment YCDC proposed that Wash Water Drainage Basin, Sludge Basin, and Lagoon should be constructed at the same time as water treatment facilities. In addition, Sludge Thickener will be added according to water quality conditions of raw water.

20. Pipeline All connection of each structure are pipelines. As for The pipe linked directly with structure, settlement should be taken into consideration. Therefore, installation of flexible joint is recommended. If they cannot be supplied, several collar joints should be installed.

21. Measurement Equipment As for measurement equipment proposed by F/S, arrangement was changed in this review.

22. SCADA YCDC and the Study Team identified that SCADA associated equipment (flow meter, Water quality measurement equipment) is included in Associated equipment of Electrical of yen loan.

23. Structure Expansion joint is set in each structure every 20-30 m. In the clear water reservoir which needs water tightness, crack-inducing joint is taken into consideration as an alternative.

24. Revised Drawings by the Review Revised drawings by review are given in the following pages.
