The Zhenjiang Sponge City PPP Project from Everbright Env starts with something very simple: standing on a once-bare concrete square, you now feel soft grass underfoot and hear water disappear quietly through hidden drains instead of pooling around your shoes.

What the project includes

Officially, China Everbright Environment calls Zhenjiang one of its representative sponge city public-private-partnership projects, combining drainage upgrades, ecological landscaping and waterlogging control across several urban zones in Jiangsu province. The company’s business overview lists sponge city development as a core part of its urban-rural environmental management segment.

In Zhenjiang, the PPP structure means the company invests, builds and then operates rainwater and drainage assets over a long concession period, while the local government pays availability fees linked to performance indicators such as reduced flooding and water quality.

How a sponge city feels

Walk a block with project manager Liu Wei on a rainy day and you see the idea immediately: curbs are slightly lower, pavements are paved with permeable bricks, and small roadside swales collect runoff instead of sending it straight into overburdened pipes.

Below the surface sit underground storage tanks and upgraded sewers designed to handle so-called once-in-20-year storm events in key pilot areas, according to planning documents cited by provincial media coverage of the Zhenjiang program. These interventions aim to cut the familiar street-lake scenes after summer downpours.

Technical features and scale

Everbright states that its sponge city solutions typically combine permeable pavements, green roofs, sunken green spaces, detention ponds and smart drainage controls to retain and reuse rainwater. The urban-rural environmental management page stresses integrated design from catchment to outlet rather than scattered projects.

For Zhenjiang, local government announcements describe a multi-phase build-out covering older residential districts and key transport corridors, with hundreds of thousands of square meters of roads and green areas upgraded in batches to meet national sponge city standards by the late 2020s.

Revenue model and risks

From an investor view, the appeal of the Zhenjiang Sponge City PPP Project is its long, relatively predictable fee stream: the city pays service fees over a concession running up to two decades, tied to operation quality and asset availability. Annual reports from China Everbright Environment describe PPP projects as contributing stable earnings but requiring substantial upfront capital.

The flip side is balance sheet pressure. Construction happens in the early years, and cash outflows can be heavy before the full fee schedule ramps up, so management under CEO Qian Xiaodong has been stressing disciplined project selection and capital recycling across the group.

What residents notice

For Zhenjiang residents, the most visible change is not the buried concrete but the parks and green corridors sitting above it. Children play on slightly springy lawns where runoff quietly trickles into planted depressions and then into underground pipes instead of gushing across asphalt.

Older residents interviewed in local media reports have highlighted fewer ankle-deep puddles at bus stops and calmer traffic during cloudbursts as curbside flooding recedes faster. Those everyday experiences are what local officials use to sell the program politically.

How it fits in Everbright’s strategy

For the company, sponge city PPPs like Zhenjiang link its traditional waste and water businesses with newer urban-environment services, broadening its role from facility operator to city-level environmental partner. That positioning is central in its strategic roadmap for integrated environmental services.

Overall, Everbright sees demand for such projects tied to China’s urban adaptation to heavier rainfall and aging drainage systems, even though the pace of new PPP signings has slowed compared with the peak years when many local governments aggressively used this model.
