1. Reduction of Pollutant Load to the environment through compliancefor water pollution and air pollution from 680 industries in 2010 andcontinue ( planning for 2014 : 2000 industries)
2. Reduction of hot spot from forest fire for 20% per year

A. Technical Aspect••••Improper on‐site treatment plant to treat both black and grey water
Need an advanced technology to install the pipe in the main roadIn some cities many high rise building already have treatment plant
Need pumping system on flat land condition

B. Financial Aspect• Need an enormous amount of financing Investment to constructsewerage system.
• Local and Central government have limited financial source• Wastewater business characteristic doesn't meet investors need,because of long term Return On Investment

CHALLENGE ------- (CONTINUE)C. LEGAL ASPECT• Dispute/unclear of job description among local institutions whoresponsible to handle wastewater management• No local regulation to manage community right and obligation inwastewater system• No Public Private Partnership guideline/standard related towastewater management system
D. CULTURE AND SOCIAL ASPECT• Lack of Community awareness in term of good quality sanitation.
• Lack of community understanding in term of wastewater treatment
plant both “ black and Grey Water” should be treatedWASTE WATER MANAGEMENTENVIRONMENTAL POLLUTION CONTROL 2010 -2012TYPE OF TECHNOLOGY FOR WASTE WATER TREATMENT PLAN
