Wastewater Management System in
Industrial Hub
28
-
Main relevant department is cleansing department and that
department issues licenses for all different industries
And also controlled permission of running and stopping of all
industries
Water and Sanitation Department is a supporting department
and making technical cooperation works

Three Industries Zones are located in pyigyitagun township
(southern part of the city) and were established in 1991-1992
(about 25 years)
Nearly 1500 Different Industries are running and working in
these industrial zones
About (100) different industries generate industrial wastewater
Mostly Industries cannot treat well their effluent and directly
dispose to nearest water bodies
30
-
Concerning with industrial wastewater disposal system, so
many meetings, discussions and press conferences were
frequently held with plant`s and factories' owners from
industrial zones
From these meetings and discussions , first wastewater
treatment system and wastewater pumping station was
established in 1997-1998
Location - Block No. (590), Taung myint ward
Waste Stabilization - (6) Pond
Pond
Land Area used - (6) acres
Capacity - 500,000 gal/days
Sizes of wastewater - Dia; (200mm) (8 inches) and
Disposal pipe (3) miles length
31
-
In 2008, many complaint and protest occurred near this wastewater
treatment system due to its bad-smell so this wastewater treatment
system was moved and constructed to another place
Second wastewater treatment system was constructed in 2008 and
southern part of industrial zone
Location - (စ်) ward, block No. (lala-22) near No.(6)irrigation over water stream
Capacity storage - 50000gal
Daily pumping - 500,000 gal/day
capacity
Disposal pipe - Dia; (250mm) (10 inches) and (2 miles )
size and length

Adjacent receiving water bodies are Thingazar Creek, Mandalay
Kantawgyi, Taung Tha Mun Pond, North creek, South creek ,
Dohtehtar waddy River and Ayeyarwaddy river
And also Pa Yam Taw stream, No.(6) irrigation over water stream
and Lap Khote Pin stream flow into Taung Tha Mun Pond
These streams are flowing near around industrial zones
The water from Taung Tha Mun Pond flows into Ayeyarwady
River through White Bridge Sluice gate which is controlled by
Irrigation Department

No specific inspection Team for Industrial Zones.
Normally inspect with other relevant departments when some
complaints and Abnormal conditions occured in industrial zone
Mandalay Regional Government (MRG) organized a joint
inspection team with relevant department to inspect the industrial
zones
Relevant departments are;
(1) Local Environmental Conservation Dept;
(2) Directorate of Industrial Supervision and
Inspection Dept;
(3) Workers Dept;
(4) Occupational Health Dept;
(5) Township Administration Dept;
(6) MCDC39
-
And then take wastewater sample from plants and factories and send
to the water laboratory
According to the result of water laboratory, the cleansing department
reissue a running permit to the factory and plant owners
After completion of inspection, the team report their findings to
MANDALAY REGIONAL GOVERNMENT AUTHORITIES

Current disposal system
All wastewater generated industries are disposing their effluent to
Doke Htawaddy River through (10) inches main pipe Line without
any treatment.
Actually all wastewater generated industrial owners need to construct
their own treatment system.
But they don’t do their own treatment system.
Because of narrow Land Area and High Treatment Costing.
Finally, MCDC considered and decided to construct central
wastewater treatment system.

Central Waste Water Treatment Plant and Collection System,
Company Name -Hydrotek Public Co.,Ltd (Thailand)
Method of Project Implementation - BOT (Built, Operate, Transfer)
Contract Period of BOT -30 Years
Type of Process - Up flow Anaerobic sludge Blanket and
activated sludge system (UASB)
Extension of Contract Period - 10 Years + 10 Years
Area of Service - Mandalay Industrial Zone
Effluent BOD5 after treatment - ≤ 50 mg/l
Main Power Supply to Central Waste Water - By MCDC
Treatment Plant and Collection System Area
Land Required for Construction of - Approx. ( 20 Acres), by paying
Central Wastewater Treatment Plant rental fee of fixed rate
Investment Cost - USD$ (18.97) million42

To solve many issues and challenges, we need to shareenvironmental knowledge to all industrial owners and residents.
To explain them clearly and to follow existing EnvironmentalLaws, Rules, Regulations and Environmental Quality EmissionGuide lines.
To discuss with the people to get understanding who has beenfeeling by unpleasant wastewater smell.
To explain them about healthy knowledge causes by water borndiseases.
It’s need to colaborate and to monitor regularly environmentalwater quality and environmental impact assessment together withother relevant departments.

Before Issue of EQEG
MCDC undertakes a major responsible organization and solvedand faced with many issues and challenges.
Used a lot of Budget for temporary wastewater treatmentsystem.
Discussed with all wastewater generated industries, industrialzone management committee and protesters .
After Issue of EQEG
MONREC become as a major responsible ministry.
MCDC is not directly concern for wastewater disposal
