Introduction of Water Quality Control Dep.

National Institute forLand and InfrastructureManagement

Water Quality Control Department
 Research Coordinator for Water Quality Control
 Research Coordinator for Wastewater System Restoration

 Researching technical standards and management methods
for sewerage facilities
 Wastewater System Division• Stock management• Earthquake countermeasures for wastewater facilities• System planning at a lower cost
 Wastewater and Sludge Management Division• Utilization of resources, energy and stocks ofwastewater system• Improving hygienic safety• Global warming measures for wastewater system

Certification of wastewater treatment process

 Schematic of effluent quality standard
on Japanese Sewerage Law
Designed effluent
quality(14 categories)
Appropriate
treatment process

Order for Enforcementof Sewerage Law
provides treatment
processes corresponding
to 14 categories ofeffluent quality

Registered treatment
process equivalent toCAS, N/DN process
Such as Oxidation Ditch,etc.

Other treatment process

Effluent quality
standard

・Newly developed process
should be certified before applying to WWTP

・Evaluate the performance and certify the appropriate
category of effluent quality

B-DASH Project

National Institute forLand and InfrastructureManagement

 MLIT conducts the new technology development
project (2011～）
B-DASH -- Breakthrough by Dynamic Approach inSewage High technology

Accelerate the government-led development ofnew technology and its practical application
 by promoting technical validation through installationof actual size plants and by formulating guidelines.
 To support overseas expansion of water business byJapanese companies

Achieving cost reduction in the sewerage
projects and generation of renewable energyDissemination Strategies of
B-DASH Technologies

National Institute forLand and InfrastructureManagement

Publishing Technical Guideline on each developed technology
Technical advise from MLIT to municipality governments fordevelopment of effective energy use in sewage works
Describing the developed technology to Design Manual on
Sewerage System

 Promoting cost reduction, energy saving and energy
generation by dissemination of the technologies in Japan
 Supporting world water-business by reflecting to international
standards etc.
