          Dutch brick, environmentally permeable brick laying in the future-Ningbo Technician College sponge equipment "rainwater garden".

Auntie Xiong, a resident of Sanhe Jiayuan, was happy to introduce the changes brought about by the sponge transformation.

"After the transformation of the residential area, the landscaping has become richer and more diverse, and the scenery has become more beautiful. The days here are the same as in the garden." "The water on the road is gone. On rainy days, the road is refreshing." 1,000 new parking spaces have been added, so you do n’t have to worry about finding a parking space when you come home from work. ”Yesterday, when reporters interviewed in a number of sponge transformation pilots, they heard many residents praise the city ’s sponge city.

The reporter learned from the municipal sponge office that since Ningbo was successfully elected as the second batch of central financial support sponge city construction pilot cities in April 2016, as of the end of February this year, the city has started 166 sponge city construction projects and 51 completed projects.

Make the community look different, residents say it ’s like a day in the garden

Entering Sanhe Jiayuan Community, Zhuangqiao Street, Jiangbei, huge trees block the sun, the oasis under the shade is full of flowers and grasses, the large and small pebbles are matched with the high and low green plants. There are lounge chairs set in the flowers and grass, and residents in twos and twos are resting and chatting.

This is the "sponge" equipment Sanyu Jiayuan has just renovated-Rainwater Garden. "Once the area was beautified, the plants were sparsely pulled, and the scene became beautiful after the transformation. We are in the garden every day like day." Said residents Zhang Xiaoying happily.

"Our community was completed in 2004. The rain and sewage pipes are aging and blocked, and some areas will show stagnant water on rainy days; part of the ground is paved with damaged potholes; the community is more messy and some local loess is bare." Xie Qingen, Secretary of the Party Committee of Guangting Community, Jiangbei Zhuangqiao Street The introduction said, "In April 2016, Ningbo City became a national sponge city construction pilot city. Sanhe Jiayuan is located in the pilot area. Residents are voluntarily renovating. After sponge reconstruction, the above problems have been well dealt with."

"Before sponge reconstruction, the rainwater from the community was discharged into the Yangshi River on the west side. In the early stage, rainwater was an important source of pollution. After filtering and purifying in the rainwater garden, it was discharged to Yangshi River, which can reduce non-point source pollution by more than 60%. Overflow equipment flows into the rainwater pipe network. The sponge reconstruction of the community is estimated to be completed in May this year. "Liu Yang, the sponge planning unit of the community and the head of Zhejiang District of China's Eco-City Research Institute, said that after the sponge reconstruction, Sanhe Jiayuan Community can respond to the problem. Once in 50 years, there is a danger of flooding.

In the Jiangbei Yaojiang Garden District, the reporter saw another sponge transformation method: a thick wild drainage pipe was added to the exterior wall of each residential building, which blended into the milky white wall. What's the use of these new drainage pipes? Shen Zheying, deputy director of the planning unit for sponge reconstruction of the community and deputy director of Panlian Nita Eco-Environment Construction Co., Ltd. said, "It is common for laundry water in the old community balcony to directly enter the rainwater pipe and flow into the river. External drainage is passed through each balcony. It collects the laundry waste water from the balcony and collects it into the municipal pipe network, which has the effect of maintaining river water quality. "

Added 1,000 parking spaces. How did this happen?

The difficulty of parking is a common problem in many old communities. Yaojiang Garden, the first old district in our city to start the sponge reconstruction project, is now basically completed. After the renovation, 1,000 parking spaces were added. How did this happen?

"Our community is an Anton community built in 2003. There are more than 2,300 households, more than 1,400 vehicles, and only more than 400 parking spaces. The problem of parking difficulties is very outstanding." Yubei, Party Secretary of the General Party Branch of Yaojiang Community, Hongtang Street, Jiangbei The runner-up said. To this end, the planning unit maximized the use of vacancies and re-divided parking spaces, adding a total of 1,000 new parking spaces. "Now we can basically meet the parking needs of residents, parking is orderly, and road congestion has been greatly reduced." Yu Yajun said.

These parking spaces also function as "sponges." "Parking pipes are laid underground. Each parking facility is a small storage space. It stores water when it rains, and it can be pumped out when needed." Liu Yang said.

The problem of parking difficulties is the same in Sanhe Jiayuan. The north gate of the residential area was originally overgrown with weeds, and the key to sponge reconstruction was to set up more than 50 parking spaces. "The parking spaces are paved with permeable bricks, and there will be no rain under light rain." Xiong Peina, a resident of the community, pointed to the ground and introduced. It is understood that there are more than 800 residents in this community, and there are only 64 parking spaces on the ground. In the sponge reconstruction, a total of 113 new parking spaces have been added. At the same time, the main road has been widened from 3.5 meters to 5.5 meters, and the traffic is smoother.

"The sponge reconstruction of old communities is a people's livelihood project, and now some old communities have achieved good results. The focus of the old community reconstruction is to deal with problems and satisfy the needs of the public. At the same time, the reconstruction of old communities must fully mobilize the participation of residents and the co-construction, co-governance, and co-governance sharing effects of the industry committees. By enhancing the cohesion and combat effectiveness of grass-roots organizations, the residents' inductive qualities will be improved and the public's sense of participation will be improved. , Feeling of gain and happiness, "said Zhang Wei, director of the Ningbo Sponge City Construction Technology General Consulting Unit and the head of the Ningbo project of the Municipal Engineering North China Planning and Research Institute Co., Ltd. of China.

Sponge transformation allows the road to "breath" autonomously

Entering the gate of Ningbo Technician College, flowers bloom in a rain garden of about 200 square meters, and plants such as cuckoo, golden leaf iris, iris, and red heather are lush. "Before the renovation, this oasis center was high and the surroundings were low. Under heavy rain, the accumulated water will flow to the road surface. After the sponge reconstruction, the oasis center became a concave land. The water on the way will pass through the overflow well and enter the ground. After filtering and purification, Emissions. "Liu Yang said.

"The sponge transformation started in July last year and was completed in October. In mid-October last year, it rained continuously for 3 days with a total rainfall of about 250 mm. The average annual rainfall in Ningbo was about 1500 mm and 3 days of rainfall. The amount is equivalent to 1/6 of the total amount of the year, indicating that the rain is very strong, but there is no water on the school pavement. "Said Chen Mingwu, director of the logistics department of the Ningbo Technical College. This sponge-like parking space has eased the problem of parking, and the storage space has increased by 200 cubic meters. "

Xiejia Road in front of the school is the first road to complete the sponge transformation in our city. Before the renovation, there were problems such as the easy accumulation of water on the pavement on rainy days, the direct drainage of rainwater on the part of the roadway and sidewalk, and the damage of bricks on the ground. After the renovation, there are openings under the roadside stones, and there are more than 480 openings on the 1,568-meter-long road. Liu Yang said, "One side of the side stone is the road and the other is the ecological tree pool. The openings for the road are set to guide the rainwater into the ecological tree pool, the pavement of the sidewalk and the ecological gravel layer under the road beautification. In this way, the quality of rainwater on the road can be purified, which can reduce pollution sources by 60%. "

In the sponge pilot project on the east side of Guangyuan Road—the green belt project on the east side of Guangyuan Road (North Ring West Road—Yunfei Road), the ecological method is also used to soak rainwater through the oasis, retain, store, and filter it, and partially supply groundwater. Part of it is guided into the river, which can reduce the pressure on the municipal pipe network, improve the utilization rate of rainwater, and maintain the Yaojiang water system.

The city's 51 sponge projects have been completed by 2030, and more than 80% of the built-up areas in the city must be qualified

In April 2016, Ningbo was successfully elected as a pilot city for the construction of a sponge city supported by the central government. In November 2016, our city issued the "Implementation Opinions of Ningbo City on Promoting the Construction of Sponge City". The policy is that by 2018, 30.95 square kilometers of the "Cicheng-Yaojiang" pilot area in Jiangbei District will reach the national sponge city pilot city. Construction check requirements. By 2020, more than 75% of the rainfall in the central urban area will be absorbed and used locally, and more than 25% of the urban built-up area will meet the requirements of the sponge city construction policy. By 2030, more than 80% of the urban built-up area will meet the requirements of the sponge city construction policy.

As of the end of February this year, 166 sponge city projects have been started and 51 projects have been completed. There are 97 start-up projects and 23 completed projects in Ningbo Sponge City pilot area. The completed public construction projects include Ningbo Technician College, Ningbo Ninth Hospital Phase II Project, and Jiangbei Experimental Education Group Binjiang Experimental School. In addition to Sanhe Jiayuan and Yaojiang Garden, the residential area sponge reconstruction project also includes Tiancheng Hometown, Tianshui Golden Collar Apartment, and Fengjia Anton House Project on Zhuangqiao Street.
