[Activities for output 1]
This output was to be measured by the following indicators through the activities at the focused STPs, Kamphaeng Phet STP and Pathum Thani STP .
Unit cost (Baht/m 3 ) is reduced by 20% at the focused STPs;
Treated wastewater is increased by 30% at the focused STPs; and
Effluent water quality meets the standard at the focused STPs.
As for the reduction of unit costs, the Project proposed many ways of cost reduction and some of them have been already employed. As for the increase of treated wastewater, the major suggestions would be employed in the later of the project period. As for the effluent water quality, the two focused STPs met the Industrial Effluent Standard in Thailand .
Major technical suggestions by the Japanese experts are as follows. Some are already implemented, and some others especially which requires considerable amount of money are now waiting the budgetary allocation.
Designing in detail for manual raked screens for PS2.
Improvement of the method of the check for the repairing works
The prevention countermeasure against break of plastic rakes
Setting of Timer Board for controlling the aerator instead of restoring of Programmable Logic Controllers (PLCs). Setting PLCs for controlling aerators so far are over-designing for simple control of the systems .
Energy saving operational method.
Pump performance test without documented-specification of Head-Flow Capacity curve ( H-Q curve)
It is revealed that these suggestions were practical, appropriate and new to Counterparts, officers in local authorities and contractors.
Beyond the focused STPs Japanese experts surveyed/visited the following STPs in the whole of Thailand and gave the technical expertise and suggestions under the request of WMA
· Central: Bang Phe (Rayong Province), Sri Racha (Chonburi Province), Phet Buri, Ayutthaya
· North: Phayao ,Chum Seng (Nakorn Sawan Province)
· Northeast: Pak Chong (Nakorn Rachasirma Provice), Tha Rae ( Sakon Nakon Provice)
· South: Pathong ( Phuket Province), Hat Yai

The followings are Reference Materials supposed to be developed in the Project. N amely Analysis of Existing Wastewater Systems, Guide for Wastewater Collection to Sewer, Pumping Station Designing and O&M had been accomplished before May 2006. Wastewater Treatment System O&M, Guide for Evaluation of Rehabilitation Works and Safety Manual for Construction and O&M were planned to be developed within Fiscal Year 2006

The five-day training on rehabilitation work for STP which targeted the officers in charge of STPs with OD system was carried out from 30 January to 3 February 2006 at Bangkok and Pathum Thani STP. Thirty (30) persons, including WMA staffs, officers of local authorities and contractors have participated in and twenty-four (24) have completed the training course.
The training was well planned and prepared. The uniqueness lies in two features of the training course, namely the involvement of five WMA senior technical officers as lecturers and the one-day practical on-site training. In addition a variety of lectures such as a officer from BMA and personnel from the private company were invited and delivered the lectures.
The posteriori questionnaire survey on the training reveals the following results.
About 86% of the participants found the lecturers very satisfactory or satisfactory.
About 90% of participants were satisfied with the practicability of the training.
The two-day training on safety and life rescue which targeted the officers and workers in charge of sewerage works, was carried out from 9-10 May 2006 at Tha Rae in Sakon Nakorn Province . Sixty-six (66) persons including officers of local authorities and contractors have participated in and fifty-three (53) have completed the training course.
The training committee in the Project is planning to organize the next training for rehabilitation works and safety and life rescue.

As for the development of information system, the Project placed an order of hardware equipment which was delivered in the end of March 2006. Five persons have undergone the intensive training on programming languages and now three of them are actively participating in the Project.
Main outputs of the Information System, which disseminate reference materials and O&M data and introduce WMA and IST Project were demonstrated in the Joint Coordinating Committee on 24 August 2006 .
[Activities for WMA Laboratory Establishment]
Aiming at establishment of WMA Water Quality Analysis Laboratory in October 2006 (Fiscal Year 2007) , the facilities of TCSW was transferred from Department of Public Works and Town & Country Planning (DPT) to Wastewater Management Authority (WMA).
Main roles of the laboratory are to implement water quality analysis service to users, to support WMA works for local administration and to contribute the capacity building of WMA.
The IST Project fully supported the establishment of the laboratory, as follows;
I nspecting and repairing equipment in laboratory
Preparing chemicals and some necessary things
Hiring a staff in charge of analysis for laboratory
Training three analysts of laboratory
Dispatching a Japanese expert to train the analysts and to support for start-up of laboratory.
