10 CHAPTER 1. INTRODUCTION AND BRIEF PROJECT DESCRIPTION 1.1. BACKGROUND AND PROJECT OBJECTIVES Background Phu Ly City is the political, economic and cultural center of Ha Nam province. It is located about 50 km south of Hanoi, on the main north south railway and national highway 1A, which is ultimately lead to Ho Chi Minh City. The city is presently small, consisting essentially of an old urban area clustered along both banks of the Chau Giang River. However, as Hanoi expands, and transport links between the capital and the south improve an expressway is under construction and a high-speed rail link is being studied Phu Ly will inevitably become a satellite city for Hanoi. In recent years, Phu Ly city has been developing continuously in its economy, politics, society and culture. The technical and social infrastructure has also been improving progressively. Nevertheless, the city is still struggling to keep up with rising demand for basic urban infrastructure including traffic systems, drainage and environmental sanitation systems, water supply systems, etc. To address these issues as well as to support its role and functions in the socio-economic development of the provincial and the wider northern region of the country, the city has prepared a master plan towards 2020 which has been approved by Ha Nam Provincial People s Committee. Ha Nam Provincial People s Committee (PPCs), which is responsible for Phu Ly City, has requested World Bank (WB) support for essential infrastructure under the proposed Medium Cities Development Project (MCDP, or the Project ). The Project will finance multi-sector infrastructure investments in Phu Ly responding to infrastructure deficits and urban services demands as expressed through the city s master plan. Specifically, the project will support infrastructure rehabilitation and improvement in the old part of the city, and new infrastructure in the new urban area into which the city will expand. The investments include surfacing existing roads and lanes in selected urban areas; extending water supply and drainage networks and linking the latter to a new wastewater plant, also to be constructed under the project; and expanding and improving several small lakes that will become part of the city s green space while also serving an important flood mitigation and retention purpose. In the new urban area, the project will finance construction of a core access road, with a bridge across the Chau Giang River that will provide a strong connection between the northern and southern parts of the city. The road will be incorporate water supply and drainage/wastewater pipe networks within its corridor, the latter connecting to the project-financed wastewater plant that is to be constructed in the northwest of the expanded city area. The project will also support the city with implementing the project, with developing a more comprehensive and appropriate approach to urban planning, and with developing the capacity to manage its expanding infrastructure assets Project objectives Short term objective - Improve and raise the living conditions of low-income residents in the project area. VIWASE-OCI Consulting Association 1

31 CHAPTER 2. NATURAL, ENVIRONMENTAL AND SOCIO-ECONOMIC CONDITIONS 2.1. NATURAL CONDITION Geographical location Phu Ly City is the political, economic and cultural center of Ha Nam Province, located in the central part of the province, at the confluence of three large rivers: Day, Nhue and Chau Giang. It is located 50 km southwest of Hanoi at the North Latitude of ' ' and the East Longitude of 105 o 54' 105 o 58'. Geographical boundaries of Phu Ly city are as follows: - The Eastern and Southern borders Thanh Liem district. - The Western borders Thanh Liem district and Kim Bang district. - The Northern borders Kim Bang district and Duy Tien district. The area of Phu Ly City is 3, hectares, of which ha is urban area. The city includes 12 administrative units with 6 urban wards and 6 suburban communes i.e.: 6 wards: Minh Khai, Hai Ba Trung, Luong Khanh Thien, Tran Hung Dao, Quang Trung, Le Hong Phong Wards and 6 communes: Quynh Chau, Liem Chanh, Lam Ha, Phu Van, Liem Chung, Chau Son Climate Condition Like other areas in the Red River Delta, Ha Nam has typical tropical monsoon climate with hot rainy summer and cold dry winter. The change between seasons results in the variation of city climate with four distinct features: spring, summer, autumn, and winter. The temperatures of summer and winter are in contrast with those of spring and autumn are transitional periods. Summer lasts from May to September; winter is from November to mid March; spring begins in mid March till in April and autumn from October to mid November Temperature The project area is located in the climate region of the Bac Bo Delta with the characteristics of tropical monsoon climate- contrasting temperature changes between the seasons. The average annual temperature is about C, average hours of daylight is hours/year. In a year, there are from 8 to 9 months where the average temperatures are over 200C (5 months of which are above 250C); temperatures fall below 200C for only 3 months and so far never below 160C (Figure 2-1).

Lượng Rainfall mưa (mm) (mm) Months Tháng Wind regime Figure 2-4: Average monthly rainfall in a year There are two main seasons: summer and winter. In the summer, the main directions are south, southwest and southeast while in the winter, main directions are North, East and Northeast Unusual weather patterns Storms affect the region from about May to November each year, causing heavy rain and strong winds with speeds of up to 100 km/h, and the normal rainfall average is estimated to be up to 1,000 mm Geomorphic and topographic condition Phu Ly city is located in the plain along rivers; the terrain is divided by the rivers and low areas. The general slope of the city s terrain is from West to East. The topographic features of the city are as follows: - The topography of the old city area in the east of Day River and new urban areas in the west of Day River is raised, reaching the elevation of 3.0 m m; - The topography of Phu Van region in the north of Day River and Chau River is also raised, reaching the elevation of 3.0 m m. - The area of rice fields and vegetable fields has an elevation of 1.8 m m. - Low areas of ponds/marsh have an elevation from to m, are the low areas north of Chau River and east of Day River where the interconnected ponds, lakes and low fields are frequently flooded. Phu Ly city is located at the intersection of the Day, Nhue and Chau Giang rivers and is enclosed by a dyke system (Figure 1-2). The water outlets to the rivers are influenced by the hydrology of the Day River. The ground water level in the area depends on the water level of the river which is subject to seasonal changes. Phu Ly city lies within the earthquake zone of warning level 8 (according to the forecasting document of the Global Physics Institute). VIWASE-OCI Consulting Association 24

34 Hydrologic conditions The annual volume of average rainfall in Ha Nam province is about billion m 3. Annual surface water run-off from the Red, Day and Nhue rivers into the territory is about billion m 3. Groundwater flows through the territory is always supplemented by those from other regions. Ground water in Ha Nam exists in many layers and is of good quality, sufficient to meet the demand for socio-economic development. Figure 2-5: Intersection of Day, Nhue and Chau rivers in the Ha Nam province - The Day River is a tributary of the Red River, derived from Phu Tho, flowing into Ha Nam territory. The Day River is the boundary between Ha Nam province and Ninh Binh province. The river has a length of 47.6 km in Ha Nam province - The Nhue River is a tributary of the Red River from Thuy Phuong (Tu Liem, Hanoi) into Ha Nam province with a length of 14.5 km, and it then flows into the Day river (Phu Ly city). - The Chau Giang River originates in Phu Ly city and splits into two branches at Tien Phong (Duy Tien) River. One branch is the boundary between Binh Luc and Ly Nhan district VIWASE-OCI Consulting Association 25

35 and the other branch is the boundary between Binh Luc and Duy Tien district. Sat River is a branch of the Chau Giang River in the Binh Luc district. According to the study on hydrology in Phu Ly city, the Chau Giang is a large branch of the Nhue River. It receives run-off from the city and then flows to the Red River. The Chau Giang River is affected by water from the Nhue river and is always polluted seriously due to a lack of circulation, leading to the adverse impacts on community s health especially those in Ly Nhan and Binh Luc district. The monitoring data for river water quality recently showed heavy contamination of water sources. Aquatic life in the rivers is very limited SOCIO ECONOMIC CONDITION Population and Population density According to statistics combined with the results of the census dated 1/4/2009, there are 19,110 households in the city, with a population of 86,920 people. The population at the administrative units is as follows (data surveyed in 2009) (see table 2-1).

Rural population accounts for 51.1%; the inner city (6 wards) accounts for 48.9% of the population of the city. The population growth rate in the period has not changed much, on average, about %/ year Occupation and Income Over the past few years, Phu Ly has achieved high economic growth rate, of which industry increases by 15-16% per year, agriculture and services increases by approx. 4% and 20% per year respectively. The economic structure is in positive form; the industryconstruction share of GDP has gradually increased and reached 37.4% in 2005; services increased by 50.3% while agriculture decreased to 12.3%. The average GDP per capita of the City in 2009 increased to 5 million Vietnamese dong. The average food consumption per capita is 186 kg. VIWASE-OCI Consulting Association 26

36 a. Industries and handicrafts Currently, Phy Ly has more than 7,800 industrial and handicraft manufacturers, including 57 state-owned enterprises, which attract nearly 12,000 employees. Most local enterprises undergo stable development and standing in the context of the market economy. Private manufacturers develop strongly in terms of both quality and quantity. Two industrial complexes are under construction in Thanh Chau and Chau Son. b. Agriculture In recent years, farmers have become active in changes to livestock and cropping patterns. Advanced farming techniques have been adopted resulting in high and consistent crop yields. The crop structures have been formulated stably, of which winter crops have become the key crops. During the periods, the agriculture output increased 2.3% per year in average. c. Commerce Service - Tourism In recent years, the economic structure of the city has shifted positively with the increased proportion of industry-construction and reduced proportion of services, agro - forestry - fishery. Table 2-2: Economic structure of Phu Ly city in 2000 and 2009 (Unit :%) Year Economic structure (actual values) Industry Construction Services Agriculture, forestry, fishery (Source: Adjustment of general master plan of Phu Ly city, Ha Nam province to 2020) Economic growth rate in 2009 was 19.9%. The income per capita has increased rapidly, reaching 23.1 million per person in Health service The health network of HaNam Province is diversified with state clinics, hospitals and private clinics. There are now 5 provincial hospitals, a city hospital and 12 commune clinics. Currently, six of twelve wards/communes have reached national health standards Education Investments in kindergartens and basic education have been focused to improve facilities and teaching quality. Currently, the city has 38 schools including 12 nursery schools and kindergartens; 11 primary schools; 10 secondary schools and 5 high schools Culture, history and tourism The cultural, historical and tourism sites in Phu Ly city are listed in the table below. In Quang Trung ward, there are two provincially classified structures: Song Nham Chi At ancestral temple of the Vu families and the Mau temple. However, in the area of construction of the Phu Ly subproject, there are no historical, cultural, or religious properties. There is only a pagoda called Lac Trang pagoda in Quang VIWASE-OCI Consulting Association 27

Planning area is under the basin drainage of Chau Giang River. Rainwater is collected in the channel network leading to Lac Trang lake through Lac Trang pumping station (capacity of 29,000m 3 /h) and a part of it during Phuoc pumping station (with capacity of 80,000m 3 /h) to Chau Giang river. Flood control system: the dyke of the Chau Giang River is from 5.2 to 5.55 m height; Nhue River s dike is the road-bed of National Highway 1A, with the height ranging from 5.4 to 7.0m. When the level of river water increased, the stop-log gate is closed and the rainwater in the entire basin then pumped into the river. Sewage system and environmental sanitation VIWASE-OCI Consulting Association 28

38 The city has a combined drainage system in the old urban areas and separated drainage system in the new urban area (Bac Chau Giang area). The combined drainage system in the old urban areas is relatively stable, while in the new urban areas, the drainage system is still under constructione. Drainage collection systems and treatment plants are being built in each area. Currently, domestic, industrial and hospital wastewater as well as agriculture wastewater is discharged directly into the storm water drainage and then into existing water bodies of the city including Chau Giang, Nhue and Day Rivers. Some assessments concerning the drainage system of the city: - The current drainage system is divided by terrain, into three main basins: the old urban areas in the East, including the southern area of Chau Giang River, East Day River; western area of Day River, and North Chau Giang; + The western area of Phy Ly city (Bac Chau Giang new urban area) has increasingly developed in infrastructure upgrading, according to the Phu Ly Master Plan, rain water and wastewater will be collected separately but the drainage system and wastewater treatment plant have not been built yet. + The center of the East area (the old urban area - South of the Chau Giang river) uses combined drainage system for both storm water and wastewater. In the newly constructed urban areas of the South (South Tran Hung Dao area, Liem Chinh, Thanh Chau...), the drainage system has been built separately for storm water and wastewater, while collection and treatment systems are under construction. + In the north Chau Giang, infrastructure of residential areas is very limited.. In the newly constructed areas, infrastructure system is not invested synchronously, storm water and wastewater drains are built separately, and the collection and treatment systems have not been built as of now. - Generally, the drainage system is limited and low in density; the drainage system is not systematic and synchronous. - Some drain systems are small in cross section, only capable of surface drainage and incapable of a regional drainage function. - Due to new urban development, the natural terrain is partitioned; lakes, canals and fields have been narrowed, causing decreases in natural drainage area. - Poor drainage system design will result in slow withdrawal of rainwater, thus causing partial flooding. - The management, construction, and maintenance of the drainage systems are inadequate, causing damage or congestion to the drain system. - In recent years, the urban drainage system of Phu Ly has been invested and constructed significantly. However, not all transportation routes have drainage facilities. Drainage system needs to be extended equally on roads and major pumping stations and reservoirs to ensure drainage for expanded urban areas as well. VIWASE-OCI Consulting Association 29

39 - Urban flood is extensive, due to stagnant water in streets having no drains and lacking pump stations and the rising water level of the rivers during flood events + Flood caused by the lack of drains leading to pumping stations; moreover, pumping stations are too small compared with the large area of the water collection basins. + Flood due to overflow of rising water level of the rivers (flood discharge of Day river). This case rarely happens. Status of drainage and wastewater treatment in the project area The areas within the scope of the project have insufficient capacity for drainage and wastewater treatment. According to surveys of the study team, there is no drainage system for stormwater and wastewater in Quang Trung Ward. The area has topographic elevation lower than roads and dykes around. Specifically: project area s average ground altitude is from +2.2 m to +3.5 m except the area near the embankment road of Nhue River of which the altitude is from +4.5 m to +5.4 m. This area is surrounded by the Nhue River dyke system (altitude +4.5 m to +5.4 m), Chau Giang River dyke (altitude +4.5 m to +5.5 m) and National Road 1A (altitude +5.9 m to +7.0 m). Among the 696 households in the project area of Quang Trung Ward, there are 437 households using septic tank toilets (three-compartment toilets) (62.78%), 29 households using simple septic-tank (4.17%) and 230 households using flushing toilets (33.05%). Hoa Lac Village of Lam Ha Commune does not have sewer system yet. The drainage is mostly done by self-penetration to the soil and discharging into Chau Giang River. Hoa Lac Village is characterized by high terrain in the middle area (altitude +4.2 m to +5.7 m), lower on both sides (North half s altitude +2.5 m to +3.7 m, South half s altitude +2.9 m to +3.5 m). Chau Giang River dyke, which is located in the North (Street TL493), has an altitude of +5.0 m to +5.5 m. The terrain of Me Noi Village, Liem Chinh Ward has an average altitude of +2.5 m to +3.5 m, sloping from North to South. Chau Giang River dyke has an altitude of +6.5 m to +7.0 m. Similar to Hoa Lac Village, the area of Quang Trung Ward, Me Noi Village does not have sewer system yet. Currently the drainage is mostly done by self-penetration to the soil and discharging into irrigation ditches in the South (near the Road 42 m, which is currently under construction) Water supply system Overview of the water supply system in Phu Ly city: The existing status of water resources systems and water treatment plants: The water resources used for water supply in Phu Ly City is surface water from the Day river. This supplies 2 water treatment plants. - Water supply treatment plant No. 1 located in Quang Trung ward, with capacity of 10,000 m 3 /day, built in Water supply treatment Plant No. 2 located in Thanh Son commune, Kim Bang district with capacity of 15,000 m 3 /day, built in 2001 VIWASE-OCI Consulting Association 30

40 Traditional treatment technologies: Raw water - Mixing - Reaction - deposition - Filter Disinfect Water supply output in 2009 was 4.5 million m 3 (16,600 m 3 /day including water loss of about 35%). The status of water supply network: The water supply network includes a pipeline that connects consumer households comprises of conveyance, distribution and services lines and various materials such as cast iron, plastic and galvanizediron pipes. About 96% of the city s population is connected to the supply network. Total length of the main pipelines is around 25km with diameter mm General assessment - Treatment plant has not yet operated at its full design capacity (about 70%) - Scope of service is primarily for the city center. The city s water supply company is not responsible for the water supply system in the districts of the province. - The applied water tariff includes environmental charges and it has currently been increased to cover sufficiently production costs - The company has been privatized therefore its management model has changed. - The loss ratios is 35%, the number of water meters is 13,300 of which 320 meters belong to state agencies. - Quality of raw water can be affected due to the pollution of water in the Day and Nhue rivers Quality of raw water can be affected due to the pollution of water in Day river and Nhue rivers Water supply status of project area The project area at Quang Trung ward consists of populated areas of groups 6-10 with 696 households and 2,868 people. The demand for clean water is at Quang Trung ward is very urgent. Clean water is only provided for 45 households living in-group 7 accounting for 6.5% of households in the project area. These include 35 households located near National Highway 1A and about 10 households located inside Highway1A about m. Water supply service network for these households consists of D32 and D25 tubes with the length of about 110 m and 250 m, respectively. These tubes were constructed in 2006 associated with the construction of the Highway 1A expansion through these households of this group. The majority of households in project areas use rainwater and well water as drinking water source. Over 80% of households have rainwater tanks, 45% of households have drilled wells. When Nhue river water is contaminated, the quality of water from nearby drilled wells is not guaranteed for people s health. Because water is not hygienic, the percentage of people suffering from diseases related to water resources in the project area is higher than the surrounding wards using clean water from the water supply company. According to the statistics of Quang Trung ward health station, from 2000 to present, in the project area the average number of people suffering from skin diseases is double that of the city.

41 Water supply system is currently not available in Hoa Lac village area. The majority of households use rainwater and well water as drinking water source. More than 75% of households have rainwater tanks, 60% of households have drilled wells. Me Noi village has previously been supplied clean water from a water supply station with 100 m 3 day capacity, from water supply Liem Chinh cooperation. Currently, this water supply station is damaged and no longer in operation. Thus, majority of the households there do not have access to clean water. In the village, there are only about 15 households along the dike road of Chau Giang river near junction with Tran Hung Dao road have access to clean water from the water supply company. Recently, due to the imperative demand for clean water, these families, from their own funds, constructed and installed a steel and galvanized pipeline which connects D32 and D25 service pipes with the length of 60 m and 95 m, respectively, to transfer water from clean water pipes in intersections for their domestic and business needs. The rest households use rainwater and water well for their domestic purpose. About 80% of households have rainwater tanks, 65% of households have drilled wells Status of solid waste management and treatment - Domestic waste: The total solid waste of the city is around 15,534 tons per year (43.14 tons/day), which is collected and treated by the city s Urban Works Company to produce organic fertilizer at a processing plant at Thung Dam Gai, Thanh Thuy commune, Thanh Liem district of the city. - Hazardous waste: To dispose of generated hazardous waste, companies in the city and in the industrial zone (small and handicraft industries) have to sign an environmental protection commitment with the Ha Nam Resource and Environment Department (DONRE) and report their waste sources, types, quantity, and composition of each hazardous waste. This information is recorded in DONRE s waste source book. The City People s Committee requires each private general clinic to have a contract with hospitals regarding health waste treatment before they are granted the environment commitment certificate under the environment protection scheme. Since October 2009, the solid waste processing plant, producing organic fertilizer using Belgian technology has been under operation. This plant is located in Thung Dam Gai landfill (Thung Ham), Thanh Thuy commune; Thanh Liem district has burial sites with the area of 14 ha. Capacity of solid waste treatment is about 55 tons per day (the residual capacity of 65 tons per day). Microbiological fertilizer products are sold by the company in the city Existing transportation status + Railway: North-South railway: runs parallel to National Highway 1A, and is a meter guage single track facility; Specialized railway runs from the Phu Ly station to the Thinh Chau station and the But Son cement factory, 5 km long, with single 1 meter guage track. + Waterway: VIWASE-OCI Consulting Association 32

Ships of up to 200T can pass through; The Chau Giang River route: 4.5 km length, average width is 130 m; min depth is 3.5 m; The Nhue River route: 3.5 km length, average width of 60 m; min depth is 3.0 m; + Roads: National Highway No.1A (Le Hoan Street) runs through Phu Ly city with 3.7 km length; the road s surface is made of asphalt concrete, sections: 5m+11.5m+2m+11.5m+5m+5m Highway No.21B: Running through Phu Ly city is 0.5 km long. The road s surface is made of asphalt concrete, 5 m in width. Highway No.21A (Dinh Tien Hoang, Tran Binh Trong, Dinh Cong Trang, and Ly Thuong Kiet Streets): Running through Phu Ly city is 9.5km. The road s surface is made of asphalt concrete, 12 m in width. Provincial Road No.971 (Tran Hung Dao street to Ly Nhan): Running through Phu Ly city is 2.5 km; 7 m in width; Cau Gie Ninh Binh Highway to the east of the project area: under construction; Inner-city traffic: The city s inner city network is based on a grid, with roads about about m apart; all roads have been asphalted. The road network in the east of the city is degraded with no pavements. The road network in west is new, and the quality is still good. Total length of the Phu Ly city s road network: 236.5km In which: + Inter-provincial roads: 29 km + Urban roads: 33.5 km + Roads in villages, hamlet, roads to field.: 174 km Traffic situation at the point of project implementation The internal roads system at project area of Quang Trung ward is underdeveloped and not appropriate for the functions of the city s inner ward. Beside Nhue river s dyke routes made of concrete has cross-section of about 2.7 m to 3.5 m, internal roads in the area are mostly earth roads (about 40%), gravel roads (about 30 %) and concrete road (about 30%). Most of the roads have been degraded seriously; some of them are often in muddy condition, especially in rainy time. Crossroads are only from 2 m to 3 m, each section has a width of about 1.5 m. The present road situation generates obstacles for economic development and people s walking and construction activity, especially in these days of heavy rain causing flooding.

43 The traffic system in the Quang Trung ward is composed of mainly alleys with small cross section, so its connection with outside residential areas face many difficulties. The region seems to be isolated, and does not fall in line with strong economic development of neighborhoods area. The system of internal roads of Hoa Lac village is underdeveloped; including concrete roads (about 45%), soil road (approximately 25%) and gravel road (about 30%). Crossroads are from 2 m to 3 m. Some roads are deteriorated and need to be renovated. The system of Me Noi village internal roads has not yet been developed including concrete roads (40%), soil road (20%) and gravel (40%). Crossroads ranges from 2 m to 3 m. Some roads are deteriorated and need to be renovated. Due to the fact that internal roads are residential alleys, main transportation vehicles are rudimentary load small vehicles, requirement for load bearing capacity of the route is not high. To match actual demand and investment cost savings, it is proposed that design standards for road load are not applied 2.4.
