BACKGROUND AND PROJECT OBJECTIVES
Background
Phu Ly City is the political, economic and cultural center of Ha Nam province It is located about
Located about 50 km south of Hanoi, the city sits on a major transport axis that connects the North–South and East–West corridors, including National Highway 1A, the North–South railway, and Highway 21 linking to Hoa Binh and Nam Dinh provinces The city remains small today, with its urban core essentially confined to an old town clustered along both banks of the Chau Giang River.
Phu Ly city has been experiencing sustained development across its economy, politics, society and culture, with progressive improvements in technical and social infrastructure; yet the city faces rising demands for basic urban infrastructure, including the traffic network, drainage and environmental sanitation systems, and water supply To address these needs and to support its role in the socio-economic development of Ha Nam Province and the wider northern region, Phu Ly has prepared a master plan toward 2020, which has been approved by the 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 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 initiative will support the city in implementing the project, advance a more holistic and appropriate approach to urban planning, and build the city's capacity to manage its expanding infrastructure assets.
Project objectives
- Improve and raise the living conditions of low-income residents in the project area.
Strengthening the capacity for stormwater drainage, expanding wastewater collection and treatment, and ensuring a reliable clean water supply will improve hygienic and environmental conditions and elevate residents’ living standards This integrated approach contributes to comprehensive infrastructure development and meets the city’s overall development requirements, building urban resilience and supporting sustainable growth for the entire municipality.
- Rehabilitate degraded roads and construct new inter-ward and inter-commune roads, thus contributing to socio-economic development
- Construct main roads and urban bridges as planned to facilitate a dynamic urban development and inter-regional exchange, and attract investments to the province
This program supports capacity building for the PMU implementing the project to ensure it is prepared and capable of delivering outcomes that meet the project’s goals in line with the requirements of the Vietnam Government and The World Bank It also delivers capacity building and technical assistance to agencies involved in urban planning and urban asset management, strengthening their skills in planning, execution, and asset stewardship to improve urban development results.
Develop Phu Ly City into a major urban hub and economic center that spearheads growth to meet Ha Nam Province’s socio-economic development objectives This transformation will serve as a catalyst for economic development across the southern area of the Northern Delta.
Investing in construction to build a robust technical infrastructure aligned with the Phu Ly City Master Plan through 2020 will attract investors and catalyze sustained economic development This momentum will help Phu Ly reach its full potential as a well-planned city and position it as a satellite city to Hanoi Capital.

Meteorological condition
Project area is located in the region with specific climate of the northern delta in a tropical monsoon, more sun and rain There are main seasons:
Winter lasts from November to April, dominated by a damp, cold northeast monsoon and frequent rainy days This weather is particularly unfavorable for agriculture, bringing persistent drizzle and northeasterly winds that create very cold, wet conditions and damage crops.
Summer season lasts from May to October, bringing hot weather and strong fluctuations that drive heavy rains, floods, and a range of weather events such as storms, typhoons, and tropical convergence zones At Phu Ly station, key climate indicators are monitored to track these seasonal dynamics, including temperature, precipitation (amount and intensity), humidity, wind speed and direction, atmospheric pressure, and other atmospheric phenomena associated with tropical systems.
Average air temperature is 23.1°C, with the warmest monthly average reaching 32.1°C in July and an absolute high of 41.5°C The coolest monthly average is 14.2°C in January, with the absolute low at 4.5°C The hottest period spans June, July and August (months VI–VIII), while the coldest period covers January, February and December (months I, II and XII).
Average annual rainfall is 1,697 mm The rainy season lasts from May to October, contributing 1,442 mm, or 85% of the yearly total The four consecutive wettest months (June to September) average 1,085 mm, accounting for 64% of the annual rainfall The dry season spans November to April, with an average of 255 mm of rainfall, representing 15% of the annual total The average rainfall for the three driest consecutive months (December to February) is 75 mm, about 4.4% of the annual rainfall The article does not provide the average number of rainy days for the year.
146.4 days from March to September Averagely, each month got about 12.3 – 17.4 days of rain. For the November and December, this two months just got 5.2 – 6.3 days of rain.
Average humidity of month is 85.1% and the absolutely lowest humidity for years is 17 – 41%. Time getting the highest humidity is February to April, about 87.6%
The average wind speed is 3.0m years/s, the maximum wind speed caused by storm and tempest or the northeast monsoon observed is 36m/s.

Hydrological conditions
The Chau River, also known as the Chau Giang River, flows through Phu Ly city with winding, meandering channels and a complex flow pattern Its mainstream approaches the left bank from Me Prison to the far end of the area, creating a distinctive watercourse that shapes the local landscape.
Me Embankment runs along the upstream segment from Phu Ly Bridge to National Highway 1A, with the mainstream hugging the right bank The riverbed is uneven, about 100–180 meters wide, and the river elevation ranges from -2 m to -4 m, with a local deeper spot around -7 m in front ofLuong Khanh Thien Secondary School This area is prone to landslides, posing danger to the households living nearby.
Chau Giang River hydrogeology: The Chau Giang water source is located in Phu Ly city and is influenced by the upstream Red River system Over many years, the dry-season water level averages about +1.2 m, while during the flood season it averages about +2.18 m The corresponding seasonal discharges are roughly 36 m^3/s in the dry season and 69.61 m^3/s in the flood season.
Annual surface water runoff entering the territory from the Red River, Day River, and Nhue River totals about 87.6 billion cubic meters, while groundwater in the region is continually replenished by inputs from other areas The Day River basin covers roughly 5,800 square kilometers and includes about 240 kilometers of river length that flows through the region.
Ha Nam province is 47 km According to Ha Nam hydrometeorology station, Day river’s water level at Phu Ly station is as following:
The driest water level: -0.14m (in dry season)
Water level of history flood: 4.72m (in 1985)
Alarm water level: Alarm 1: +2.9m; Alarm 2: +3.5m; Alarm 3: +4.1m (according to Decision 632/QDTTg dated May 10 th , 2010 of Prime Minister at Phu Ly station).
Day river’s flow is about 105 m 3 /s in dry season and 400 m 3 /s in rain season
The Nhue River is a 14.5-kilometer-long tributary of the Red River that originates in Thuy Phuong, Tu Liem District, Hanoi, and flows into Ha Nam Province where it ultimately joins the Day River near Phu Ly City The river provides water for agricultural irrigation in its basin, but the area also receives the majority of Hanoi’s wastewater and rainfall runoff, underscoring the importance of integrated water management in this region.
