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.

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.
The Project for the Improvement of Water Supply, Sewerage and Drainage System in Yangon City Vol IV Water Supply System Feasibility Study, Appendix
I-2
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.
The Project for the Improvement of Water Supply, Sewerage and Drainage System in Yangon City Vol IV Water Supply System Feasibility Study, Appendix
I-3
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.
