3 Sewerage Project Type Treatment Plant Construction Project Title Denpasar Sewerage Development Project (DSDP) Location Bali, Republic of Indonesia Ministry of Public Works, Directorate General of Human Settlement/ JICA Project Period October 2004 December 2008 Denpasar is the residential and economic center of Bali Island, and adjacent coastal areas of Kuta and Sanur are international resort areas with beautiful beaches in tropical nature and holding theatrical activities in traditional culture. In 2000, about 1.5 million foreign tourists visited Bali and spent US$50 million. However the development of these areas and tourism industry is deteriorating the local environment. Maintaining the beautiful beaches and water nature is essential for maintaining the Bali tourism industry. Based on the master plan, overall sewerage development area was defined as an area which generates heavy wastewater pollution from resident and tourist area. The aim of this sewerage system is to transfer wastewater generated in households, hotels and others to wastewater treatment plant (WWTP) through sewers and pumping stations. Phase1 of the project covers of 1200 ha in urgent area (30% of overall area). The Project started in 2004 and was completed at the end of The Project comprised two ICB packages and five LCB packages which are outlined below.

4 Sewerage Project Type Sewerage Facilities Construction Project Title Cauvery Water Supply and Sewerage (CWSS) Location Bangalore City, Karnataka State, Republic of India Bangalore Water Supply and Sewerage Board (BWSSB) Project Period Raja Canal Sewage Treatment Plant The original Bangalore sewerage system served a densely populated area in the heart of the old city since With the growth of the city, a major sewerage construction program commenced in Today almost 209 km 2 is covered by sewerage systems consisting of 3 distinct drainage zones (namely, Vrishahavathi, Koramangala & Challaghatta, Hebbal) and three minor valleys. Although three sewage treatment plants are operated in these areas, further measures had to be taken to collect and treat increased sewage flow which accelerated eutrophication in rives and marshes in the city. Hence, the Government of India requested the Japanese Government to design and construct new sewerage facilities for the peripheral area which had its water supply increased by the water supply component of CWSS Stage IV Phase 1. We conducted a review of basic design and project management for detailed design, preparation of bidding documents, bidding and supervision and monitoring for construction works. We adopted two different treated systems: activated sludge for 5 plants and activated sludge + up-flow anaerobic sludge blanket for 2 plants based on the technically and economically appropriate treatment process. Actual Project Recommendations Sewage Treatment Plant : 7 Plants (15,000-75,000 m 3 /day) in total 245,000 m 3 /day Activated Sludge for 5 Plants Up-flow Anaerobic Sludge Blanket + Activated Sludge for 2 Plants Sewage Pumping Stations : 8 Pumping Stations Trunk and Collector Sewers : Diameter = m, Total Length = 60 km

5 Sewerage Project Type Sewerage Facilities Construction Project Title Ho Chi Minh City Water Environment Improvement Project Location Ho Chi Minh City, The Socialist Republic of Vietnam People s Committee of Ho Chi Minh City Project Period 2002 ongoing (as of 2012) Although the original urban drainage and sewerage system (combined system) constructed in 1870s were improved from 1950s to 1975, the old facilities were designed for a population of 1.5 million. The present population is more than 5 million which caused rainfall runoff increase because ground surfaces are covered by roads and buildings. Therefore, during the monsoon season, floods have occurred several times in the existing urban area. In addition, domestic and industrial wastewater of 729,000 m3 with a pollution load in terms of BOD5 of more than 193 tons was discharged daily to rivers and canals without any treatment. This pollution load deteriorates the water quality of rivers and canals to an unacceptable level. Hence the Government of Vietnam requested the Japanese Government to design and construct new treatment facilities. OC Global conducted master plan, feasibility study, basic design and detailed design of this project since In 2002, we started to work as a project management consultant and to assist the client through the modification of detailed design and the bidding process. Our services were as follows: Updating and supplementation of detailed design prepared in the previous stage Finalization of the detailed design, quantity, cost estimation and tendering documentation Assistance in Pre-qualification process Study on institutional development Technology transfer on sewerage operations Coordination with the client and JICA Construction Supervision Actual Project Recommendations Sewage Treatment Plant : Total Capacity = 423,000 m 3 /day, Modified Aeration Process Sewage Pumping Stations : 2 Storm-water P/S (Q=42 m 3 /m x 2sites), 1 Sewage P/S (133.3 m 3 /m) Canal Improvement : L = 3,158 m, L = 4,128 m Interceptor Sewer : Main φ mm L = 6,540 m, Secondary φ mm L = 6,540m Conveyance Sewers : Double-cell Reinforced Concrete Box Culvert (1.3 m x 1.2 m x 2), L = 3,574 m Improvement of Existing Combined Sewers: L = 9.6 km

6 Solid Waste Project Type Municipal solid waste Project Title The Study on Integrated Management Plan of Municipal Solid Waste in Havana City Location Havana city, Republic of Cuba Japan International Cooperation Agency Project Period Landfill site Workshop in Habana city Havana city, the capital of Republic of Cuba is a center of economic activities with population of 2.2 million and area of 727km2 and the old town (known as Old Havana) is registered as World Heritage site. The following issues were identified in solid waste management: Insufficient 3R (Reduce, Reuse, and Recycle) The City generated 2,200 ton/day of solid waste in 2004 and 97% of the amount was dumped at final disposal sites; that means most of the waste was disposed in final disposal sites and reuse and recycling rate was significantly low. Solid wastes were not collected by sorted garbage but mixed. Industrial and medical wastes were quite frequently included in the mixed solid waste. This collection system made difficult to collect resources from the mixed solid wastes and to produce compost effectively. Lack of maintenance due to deterioration The efficiency of solid waste collecting was low due to lack of maintenance of solid waste collecting vehicles and heavy machines. The garbage trucks were antiquated and the maintenance was not easy due to shortage of tools, spare parts besides a limited budget Limited life span of landfill sites Existing landfill site capacities were insufficient and lifespan of the sites has been shortening. There was an expansion plan of Calle 100 landfill site but the life span was estimated only until Therefore, new landfill site was necessary to raise the limitation. Improper solid waste disposal system Survey of this project found that 50% to 60% of the generated municipal waste from household and business sectors is composed of organic matter such as garbage. Utilizing the organic matter for producing compost leads to long life of final disposal sites. There were three compost yards in 2004 but the production was not good quality as the production process was not proper as they were dumped on fields, receiving direct sunshine and rainfall due to lack of facilities and equipment. Demand of compost is high in Cuba. If high quality compost is produced from the collected garbage, it is sold as soil conditioner in the market. Environmental issues Environmental issues were identified on the solid waste management as follows: 1) overflow of garbage from the containers, scatted waste around containers and partial illegal dumping in the city, 2), environmental deterioration in the vicinities of final disposal sites due to scattered waste, odour, a fire, breading of insects, and quality deterioration of surface water; also groundwater as soil-covering was not applied and leachate was discharged to public water bodies without treatment, 3) air pollution by automotive exhaust gas from aging collecting vehicles, 4) potential risk to residents and especially workers who are responsible for collecting garbage due to possible industrial and medical wastes. Environmental and social issues Environmental and social consideration guidelines were established in Havana city, but the system did not work properly. For instance, public hearings should be held and the results and issues should be included in the final report, but it was not carried out. There were serious negative environmental issues towards residents around the existing landfill sites as described in the above item 3). The health risks and issues that residents faced generated a movement against the construction of new disposal site.

7 Hence, Republic of Cuba requested the implementation of research to settle on an integrated management plan of municipal solid waste in Havana city. Thereafter, the Japanese government determined the implementation and Scope of Work by agreement between Havana city and JICA. Consulting Services OC Global carried out the following consulting services to provide solutions for the above issues. Support in formulating master plan of the waste management in Havana up to the target year of 2015 Support in conducting the feasibility study on the prioritized projects Promoted the human resources development and the technology transfer concerning investigation and planning for the counterparts Formulated Long Term Vision targeting 2015 and the Master Plan Conducted the F/S of the priority projects selected in the Master Plan Implemented pilot projects aiming to improve the existing final landfills, to promote environmental education and public sanitation and established citizen participatory system of waste collection Held workshop for raising awareness of residents to waste treatment including collection and separation of wastes and for developing capacity of counterparts

8 Project Type Project Title Water Supply Special Assistance For Project Implementation (SAPI), Construction and rehabilitation of Water Treatment Plant (WTP) Zletovica Water Use Improvement Project Location Probistip and Stip, the Zletovica basin, Macedonia Project Period Ministry of Agriculture, Forestry and Water Economy, Macedonia / Public Enterprise Hydrosystem Zletovica (PEHZ) /JICA UF Membrane at Probistip WTP Sedimentation Basin at Stip WTP Zletovica, located in the north-eastern region of the Former Yugoslav Republic of Macedonia faced water shortage during summer season. At Probistip, before the WTP construction, the water system was made up of shallow wells, a reservoir, and chlorine dosage equipment. The pump and piping were antiquated so that frequent failed supplies were caused by the breakage in addition to a shortage of water in summer season. At Stip, before the WTP rehabilitation, tap water was supplied through a WTP using raw water pumped up from shallow wells that made pump operation expensive and the WTP structure was poor since surface concrete had flaked off and the reinforcing bar was exposed. Thus, Probistip and Stip municipalities were seeking an additional economical, stable, clean and safe water source and the new WTP as well as rehabilitation WTP to treat the Zletovica water. Project background The Zletovica Basin Water Utilization Improvement Project, the first Japanese ODA Loan project in Macedonia, began in 2003 to supply raw water to municipalities in the Zletovica river basin, was comprised of four packages: 1) construction of an access road, 2) construction of the multi-purpose Knezevo Dam, 3) construction of two intakes downstream of the Knezevo Dam and transmission pipelines from the intakes to municipalities, and 4) installation of SCADA. The water quality from upper stream of the Zletovica River is clean with the turbidity in Nephelometric Turbidity Unit (NTU) at usually less than 2. WTP constructions were supposed to be implemented by the local governments within their budgets, however budgets were insufficient. In 2011 construction of the Probistip WTP and rehabilitation of the Stip WTP were included in the JICA ODA loan project upon request from the Macedonian Government. Slovenian Government grants were also applied for the works. Assisting Ministry of Agriculture, Forestry and Water Economy and PEHZ in the construction and rehabilitation of WTPs in terms of administrative and technology matters Carrying out design review, tender assistance, construction supervision of Construction and rehabilitation of Probistip and Stip WTP Assisting Probistip municipality and Stip municipality in reaching an agreement to receive Slovenian Funds Actual Project Works Probistip WTP (New construction) UF membrane (Population to be supplied: 16,000, Design capacity: 6,480m 3 /day) Sufficient gravity pressure to the UF filtration from the intake was the element to select the UF system for the treatment system, which does not require pumps.
