Institutional Challenges

Increased flooding caused by climate change impacts is a challenge for many cities both in developing and developed countries. The existing storm water drainage systems in place have to be physically constructed and expanded to meet the water run-off challenge. This is an expensive run-off management undertaking for resource poor countries such as Tanzania. Landscape based storm water management (LSM) is put forward as a sustainable option to manage storm water run-off and it also addresses water scarcity problems in under-served urban settlement. However its implementation in cities that are faced with informal residential development is challenging because among other things, LSM requires land for implementation as well as the collaboration of different institutions, disciplines and actors. Drawing from data and information obtained from the Water Resilient Green Cities Africa (WGA) Project in two cities of Africa, this paper explores the planning and institutional challenges for LSM in Dar es Salaam, a rapidly urbanising city. The paper also presents opportunities inherent in the process some of which suggest that local institutions offer a critical platform to collaboratively plan and implement LSM in rapidly urbanising cities.

AbstractBioretention basins/rain garden is a very suitable low-impact development (LID) practice for storm water management around the globe. By using this practice in urban areas, flash flooding problems can be decreased and the environment of an area can be improved. The concept of bioretention was introduced a few decades ago and has been proven to be the best management practice (BMP) for storm water in urban areas. Due to urbanisation, natural surface areas are converted into hard surfaces such as roads, through which water cannot infiltrate into the ground. Due to this, infiltration decreases and surface run-off increases, which causes depletion of ground water continuously. In this study, we mainly explain the bioretention concept and its function as derived from different studies. This review includes different scientists’ results for the performance of the bioretention system at different locations. A summary of the research findings by different scientists on the performance of bioretention systems is also provided, including the hydrologic and water quality performances. Finally, future work necessary to enhance the performance and widespread use of bioretention systems is also explained.

Oil Water

Oil contamination in the Storm water has been generally overlooked, even though it causes major environmental pollution and is a substantial threat to all the species in the ecosystem. Likewise, the treatment of oil-contaminated Storm water in public areas and general industries, especially in airports, has largely been ignored. Airports are known as one of the most potent oil contamination contributors through the jet fuel that pollutes the local waterways and Storm water. However, little information regarding the specific actions taken to treat the Storm water contaminated with jet fuel oil in airport facilities, is available.The objective of this paper is to discuss the Storm water management that using the oil-water separator system in airports contaminated with oil. Specifically, this paper highlights the contaminants of Storm water run-off from airports and the oil-water separator system in airports.The use of a corrugated plate interceptor (CPI) for Storm water management in airports was discussed.The success in treating Storm water largely depends on the improvement of infrastructure, the capturing of pollutants and nutrients from the Storm water flows, in addition to the use of wetlands to improve the ecology and water quality of streams and rivers. Incorporating an oil-water separator system into the Storm water treatment system in the airports setting is quite significant since the airport is known for its large and paved areas containing oil, grease or jet fuel.The treatment of the airports Storm water contaminated with oil, grease and jet fuel could significantly reduce the contamination for a cleaner environment. The CPI can be used to separate the oils from the water and then retains the oils safely until removal.

Inland Inundation

<p>With the rapid pace of urbanization and drastic transformation of economic form, Wuhan, a central city of China is facing serious inland inundation problems in recent decades. This study intends to alleviate Wuhan’s storm water management problems in a sustainable way and give suggestions as to the improvement of residential area storm water management and lakeside wetland protection. Based on the data provided by Geographical Information System, analysis is done to the land form of the whole city and the change of its lake areas, which evidently demonstrates the influences of economic development on the natural environment of the city and reveals the causes of the inundation problems. Taking the population growth, land use and climate change into consideration, this research argues that strategies such as green roof fostering, neighbor-hood water reuse and wetland conservation can make a difference in stormwater drainage and prevention of inland inundation in Wuhan.</p>
