4.2.4 Investigation of related managers of Matsue Park

The author interviewed Shanghai Yangpu Landscaping Construction and Maintenance Co., Ltd., Songhe Park Director and duty personnel (including teahouse management personnel) on the design of Songhe Park water comprehensive utilization service system.

Shanghai Yangpu Landscaping Construction Maintenance Co., Ltd. (hereinafter referred to as the garden company) is responsible for the daily operation of the community park. The relevant person in charge of the garden company said that it has been paying close attention to the problem of water waste and pollution in Songhe Park.

It also pointed out that the other nine community parks in Yangpu District are facing the same problem. Due to the limitations of the water structure of the park, the water pollution in the park and the downstream of Yangshupu Port requires the investment, manpower and equipment to be rectified every year. Other water services rely on tap water, but the water consumption is increasing every year.

At present (2018), the garden company has been entrusted by the relevant departments to carry out actions on the water environment management of the Yangpu

District Community Park, and publicly invite the public to bid for the water quality improvement plan. The garden company manages and maintains the park from the work content, and essentially recognizes the sustainable development of water services. The company is in favor of using water in the park as one of the park's water sources. The person in charge believes that Zhongshui can be obtained from the wastewater of the park and surrounding communities and is satisfied by simple diversion and purification.

The person in charge of the garden company also counts that Songhe Park has an annual operating cost of more than 500,000. The use of water can reduce the water fee of the park, and the water body can reduce the related expenses. If these measures can be applied to other community parks, each year. Save hundreds of thousands of dollars on water services in community parks. However, the need for pipeline renovation and the construction of a purification system requires a mature design, and there is no further action plan in this regard.

The director of Songhe Park and the staff on duty expressed support for the park to save water and improve the water environment of the park. At the same time, it also pointed out that the current management of the park on water services is difficult. The director thinks that the original design of the park's observation pool and fountain is mainly for viewing function. The bottom of the pool is closed. The water is not flowing, and the water quality will only get worse and worse. Every year, the water is replaced, or the bottom of the pool is cleaned. Considerable trouble, it is recommended that the pool water can be circulated and purified, reducing water pollution and unnecessary management costs. The director also believes that the use of tap water as the main water for the park since the establishment of the park, such as flushing water and plant irrigation water, is indeed quite wasteful. If the pipeline can be retrofitted, the addition of the water pipeline will be beneficial to the future water service operation.
