Promotion of Sponge City Construction throughout the Territory
01 On April 26, 2021, the official website of the Ministry of Finance posted
the \"Notice on Carrying Out the Exemplary Construction of Sponge Cities
throughout the Territory\", which was jointly released by the General
Office of the Ministry of Finance, the General Office of the Ministry of
Housing and Urban-Rural Development and the General Office of the
Ministry of Water Resources. According to the document, in the period
covered by 14th Five-Year Plan, the three ministries will decide upon
some cities with good basic conditions, high enthusiasm and outstanding
characteristics through competitive selection to carry out the exemplary
and systematic construction of sponge cities throughout the territory; the
central financial will give ration subsidies to the exemplary cities.
Through the procedure specified in the above document, the three
ministries organized experts to review the exemplary competitiveness in
the systematic promotion of sponge city construction throughout the
territory in 2021.
Based on the results of the onsite review, the highest scoring 20 cities have
been selected as the first batch of exemplary cities, including: Tangshan,

A sponge city is an oasis
Sponge city means that a city has good \"flexibility\" in getting adapted to
environmental changes and responding to natural disasters. When it
rains, the city can absorb water, stores water, enables the infiltration of
water and purifies water just like a sponge. When necessary, it can
\"release\" the stored water for utilization so that the city can turn into a
super sponge that can absorb rainwater, filter air and filter out pollutants
to achieve the benefits of lowering temperature, preventing flood,
combating drought and reducing carbon. Sponge city is exactly an \"oasis\"
mode derived from the sustainable development of human habit. It has
come into being to address the problems in the water ecology of artificial
cities and is an important development mode of future cities that are in
harmonious coexistence, environment friendly and low in carbon .

Policy Support for Green Buildings
For all-round implementation of the spirit of the 19th CPC Congress and its Second, Third and
Fourth Plenary Sessions and for in-depth implementation of the ideas of Xi Jinping about ecological
civilization, this plan has been made as required by the \"Notice of National Development and Reform
Commission on Distributing the 'Mater Plan for the Campaign of Creating Green Life'\" (Fa Gai
Huan Zi [2019] No. 1696) to drive the quality development of green buildings.
By 2022, we have witnessed an area of green buildings that accounted for the new urban buildings
constructed in the year, continuous increase in star-class green buildings, constant rise in the energy
efficiency level of existing buildings, unceasing improvement of the health performance of
residences, rising proportion of assembled construction mode, further expanded application of green
building materials, all-round promotion of the supervision by users of green residences and people's
enthusiastic participation in the activity of creating green buildings, all contributing to formation of
a social atmosphere that advocates green life.
A planted top plate or roof is itself a green structure. CKS Oasis Rainwater Management System can
eliminate the structural layers of leveling layer, protective layer and sloping layer. Meanwhile, it can
the organized infiltration, retention, storage and reutilization of rainwater to meet the control item in
the standard for evaluation of green buildings: saving of resources and livable environment.
National \"Dual Carbon\" Strategy
In December 2020, the Information Office of the State Council released the white book \"Energy in
China's New Era\", which clearly portrays the \"Roadmap\" for China to achieve carbon neutrality by
2060. At the central economic working conference held recently, the achievement of \"peak carbon
dioxide emission in 2030\" and \"carbon neutrality in 2060\" was listed as one of the 8 key tasks of 2021.
The objective of carbon neutrality is an action taken by China in response to global climatic change
and highlights the assumption of responsibility by a big power. It has become a national strategy.
Planted top plates or roofs can effectively reduce the emission of carbon dioxide. CKS Oasis
Rainwater Management System can shorten construction period, save energy, reduce emission and
achieve the recycling of rainwater.
In its continuous exploration of green building technologies, CKS started to develop rainwater management technologies and related products in
2007 and, in 2009, took part in compiling the product standards of the industry for rainwater management. Through a decade of practices, it has
accumulated rich experience in the products, technologies and projects of rainwater management system and introduced the \"CKS Oasis Rainwater
Management System\".
Oasis originally means a place of abundant water sources, lush plants and exuberant vitality. CKS Oasis Rainwater Management System has
extended the meaning to denote ecology, environmental protection and the common stable and sustainable development of humans and the
nature. The aim is to build a harmonious and wonderful human habitat and create a comprehensive system for the reasonable utilization of urban
water resources, which is full of vigor like an “oasis”, self-contained, low in carbon emission and energy-saving, to facilitate achievement of the
national development goals of \"carbon neutrality\" and \"peak carbon dioxide emission\" and enable the construction of sponge cities.

PART THERE
05 CKS Oasis Rainwater Management System is composed of three parts: Planted composite waterproof system, protective siphon drainage system,
rainwater collection & utilization system. The designed structure features low carbon, energy conservation and good \"flexibility\" in suiting
environmental changes and natural disasters to achieve the functions of waterproof, drainage, water collection, storage and purification that
combine waterproofing, drainage and utilization. It contributes to the formation of \"oasis\"-like urban cluster of buildings and represent the major
development direction for urban construction and planning.
According to Article 3.0.7 of \"Technical Rules for Planted Roof Projects\" JGJ 155-2013, the waterproof layer of planted roofs should meet the
requirements for class-1 waterproof and must have at least one layer of waterproof materials having the performance of resisting root puncture, and
the materials used for the waterproof layer should have good compatibility.
3.1 Planted Composite Waterproof System
Manual of CKS Oasis Rainwater Management System
Composition of the System
The protective siphon drainage system is composed of HDPE waterproof & drainage protective board, siphon drainpipe, air permeable tube, observation well
and infiltration enhancement device.
Operating Principle
The water that infiltrates into soil continuously flows to the siphon drainpipe through the HDPE waterproof & drainage protective board. A vent
pipe is installed on the siphon drainpipe for the water inside the drainpipe to quickly gather at the outlet under the effect of space, gravity and air
pressure. Using the method of pipe tapering, the outlet causes the straight pipe of siphon to form full flow, thereby forming a siphon. The water in
the siphon drainpipe is continuously sucked into the observation well, where it is discharged into the rainwater collection and utilization system.
Thus, a shift takes place from the past passive squeezing drainage to the present active siphon drainage, thereby really achieving organized drainage
of zero slope.

Comparison between the siphon drainage system and the node layer of traditional
planted roofs
Following the ecology first principle, the system combines natural routes with artificial measures.
Under the precondition of ensuring safety in urban drainage and prevention of waterlogging, it has realized the storage,
infiltration and purification of rainwater in urban areas and promotes the utilization of rainwater resources and protection of
ecological environment.
Composition of the System
The rainwater collection and utilization system is composed of
rainwater sewage interception & hanging basket device,
discarding filtering device, water storage system and
purification system.
Operating Principle
A rainwater cistern (composed of several rainwater modules)
is installed underground to collect rainwater through the
collection pipe, which is then purified through the rainwater
purification device to reach the designed standard for use.
Then, the water is fed to the ground through the discharging
tube of the water pump. The rainwater on a roof is relatively
clean and contains less impurities, mud and other pollutants. It
can be discharged into the water storage system directly after
discarding and simple filtration to be treated before use. After
being treated, the rainwater is used to wash toilets, sprinkle
road surfaces, irrigate lawns, replenish the water of
waterscapes. It is even used as circulating cooling water and
fire control water.

CKS New Modular Cistern Cistern of Steel Reinforced Concrete and
Stainless Steel
The cisterns of concrete and stainless steel have high
requirements for structure, construction technology
and worksite conditions, and need the support of
large machinery.
A cistern of concrete has poor crack resistance, a
short service life and easiness in causing seepage.
A cistern of concrete involves complicated
construction technologies, many processes (mould
erection, steel binding, concrete pouring,
maintenance). Its construction period is long so that
work is seriously affected by season and weather.
The heavy deadweight of a concrete cistern is easy to
cause uneven precipitation
The surface of a stainless steel cistern has a low load
bearing.
For the cisterns of concrete and stainless steel, the
materials cannot be recycled after being scrapped and
may cause secondary pollution of environment.
Once damaged, the cisterns of concrete and stainless
steel are hard to repair and consolidate. They are also
hard to clean and high in cost.

to result in simple work and remove the
need for large machinery. The modules can
be assembled into boxes on the site to
complete digging and backfill on the same
day.
Fast Transportation
Very convenient transportation. Split
design is used to enable arbitrary
disassembly of the modules, thus saving
precious transportation space.
Environmental Protection
CKS rainwater collecting modules are made
from recycled environment-friendly
materials. They are deeply buried
underground without damaging the entire
ecological environment, simple to maintain
and easy to clean. They can also be recycled.
Low Cost
Compared with traditional cisterns, CKS
rainwater modules have reduced time and
the cost of manpower, transportation and
later maintenance from multiple aspects.
Strong Bearing Capacity
The modular structure has exceptional
bearing capacity. Therefore, the ground
above a cistern can continue to function as
landscaping, square, sidewalk, driveway
and parking lot.

Scope of Application
Product Profile
The PP modules of cisterns are made from polypropylene materials and enable.
95% of the water storage space to achieve water retention of higher elevation.
The unique appearance and structural design equip them with exceptional stress
tolerance. Considering that major stress comes from above the modules when they
are in use, the design has increased the thickness and strength of sideboards and
small boards so that the vertical stress reaches an extremely high level. Meanwhile,
the height is designed to be 500mm for firmer placement during installation of the
modules. The entire design has resulted in excellent bearing of single modules.
Sliding buckle is used between the small boards and sideboards to slide all the way
through for more convenience in installation. The assembly of a single box needs
only 3 steps to be completed quickly, thus greatly shortening the time of assembly
and saving precious time and labor.

Product Profile
Composed of filter screen, basket, hull and hook, the product is used to intercept
the wastes that cause serious pollution in the early period of a rainfall. The
combined use thereof can effectively intercept pollutants, which will all fall into
the basket. During regular inspection, just uncover the unit and use a hook to take
out the basket and dump everything in it. Highly convenient.
The device is used to automatically discharge part of the rainwater causing serious
pollution in the early period of a rainfall and provide preliminary filtration of the
rainwater collected later. At the initial stage, a small quantity of rainwater directly
pounds the stainless steel ball that controls the sewage pipe. Before the ball shuts
down the pipe, a small quantity of rainwater is discharged directly through the
sewage pipe under the effect of gravity. After the rainfall increases, the stainless
steel ball will shut down the pipe directly to cause the rainwater to change its flow
direction and run toward the filter screen and complete the process of discarding
and filtration through the collection pipeline. The discarding quantity is
controlled by an internal spring. Currently, the quantity of rainwater that can be
discarded is 5-10% of the rainfall, equal to about 2mm of rainfall each time.
Product Profile
The product is made from PE material, with a built-in filter screen of 304
stainless steel that has a filter precision of 0.4MM. Inside the device is an
umbrella-shape water flow changing structure that can cause over 90% of the
rainwater to flow in the direction of collection after passing through the filter
screen. Meanwhile, it can cause wastes to be discharged through the sewage outlet
on the bottom to achieve the function of automatic filtration of rainwater.

Construction Process
Plan the snapping of lines according to the locations on the
construction drawings;
Lay the strong adhesive tapes with the planned snapping line as center;
Lay the siphon drainpipe;
Lay the HDPE waterproof and drainage protective board;
During the laying of the HDPE waterproof and drainage protective
board, the sheets are required to unfold naturally and spread top-down
relaxantly along the side wall. During laying, the sheets should be flat,
neat and free of any wrinkle;
Lapping treatment: According to design or actual requirements,
bonding or welding may be selected. On the long side, the lapping
length is 100-150mm; on the short line side, the bulge needs a lapping
of at least 100mm before bonding and sealing treatment. For
installation of the HDPE waterproof and drainage protective board,
the laying is done directly on the side wall. The splicing of sheets uses
self-adhesive tape lapping or welding.
Treatment of drainage outlet and bulge: As required by design,
where a place is reserved for the drainage outlet, cut out a hole
for the HDPE waterproof and drainage protective board to
connect with the drainage system on the entire side wall. Where
the cutting is made, CKS tapes or sealant needs to be used for
sealing to ensure the integrity of the board. For the bulge, a hole
also needs to be cut out before CKS tape or sealant is used for
sealing.
Install air-permeable observation tube and dust cover;
Lay the geotechnical cloth to cover the siphon drainpipe; bond
the seams of the geotechnical cloth;
Install the siphon tube according to the working drawing;
Install the observation well according to the working drawing;
the height of the observation well is decided by the thickness of
the earthing.
