Potential Applications

Pervious concrete is one of the materials with potential applications in the construction industry because it can help reduce environmental problems caused by conventional concrete, improve storm water management, and provide a low-impact development alternative. Pervious concrete has numerous advantages, including assisting with water filtering and lowering pollutants. The ability to reduce storm water runoff is the most important feature that attracts the attention of pervious concrete. The objective of the present investigation is to evaluate the properties of pervious concrete and compare them with normal concrete. On the other hand, the requirement for aggregate to produce concrete is high, while natural resources are reduced. An attempt was made to use Black Marble Stone Waste Aggregate in concrete by replacing natural aggregate at a ratio of 0, 50, and 100%.To obtain the behavior of pervious concrete, compressive, shear and bearing strength are evaluated. A total of 54 specimens were casted and tested in this experimental work to study the behavior of concrete. To assess the shear and bearing strengths, a regression model was developed.

The City

The Cities of Mesa and Glendale, with a grant from the Water Infrastructure Finance Authority of Arizona (WIFA), partnered and developed a Low Impact Development (LID) Toolkit. This toolkit is a 100 page document that responds to the need to better manage the storm water runoff and reduce the need for very expensive expansion of drainage infrastructure. The solution to this problem justifies the need to use LID in Mesa. In 2014 the City of Mesa experienced flooding which affected many. Although LID solutions was considered at the time of this flooding event, it became a priority to identify potential solutions. The LID toolkit responded to this and is intended to minimize the harmful impacts of flooding by setting best practices related to the management of the rainfall-runoff process. The LID toolkit identifies and lists best storm-water City of Mesa management practices and national and regional LID best practices. This list and publication is intended to encourage City and private planners, designers and residents alike towards the practice of more sustainable design. The article presents the history of LID design and discusses the benefits of using LID tools.

This chapter focuses on a variety of projects that have implemented low impact development principles and construction materials. The featured projects have been designed to manage urban storm water runoff by either storing and reducing runoff volumes, or treating the water so cleaner water is returned to streams and waterways. A particular emphasis is placed on alternative material used in contrast to traditional material usage and approaches, as well as the challenges, associated with changing traditional mindsets.

Reduction Effect

Low-impact development (LID) methods are an important approach to storm-water mitigation. Modeling the effects of these installations using rainfall-runoff simulations can provide useful data for future design and implementation. In this study, we used the Storm Water Management Model to assess seven types of LID installations (vegetated areas, garden pots, tree filter boxes, permeable pavement, infiltration ditches, rain barrels, and infiltration blocks) at a South Korean industrial site. Using both short- and long-term simulation periods and distinct sub-basins within the study site, we were able to assess LID performance at the combined watershed, as well as at one LID facility. All LID types showed reasonable performance for storm-water runoff reduction, though rain barrels were the least effective. The effect of rainfall runoff reduction on LID facilities is changed according to rainfall depth (annual precipitation, monthly rainfall), the ratio of drainage area and facility capacity. We concluded that SWMM-LID modeling can effectively support the management of LID installations by providing additional design and planning data to better mitigate the effects of storm-water runoff.

Water Tanks

As a result of urbanization, the pollutant discharges from sources such as treatment plant effluents and polluted stormwaters are responsible for an unacceptable water quality in the receiving waters.In particular, combined sewer system overflows may produce great damage due to a shock effect. To reduce these combined sewer overflow discharges, the most frequently used method is to build stormwater storage tanks. During storm water runoff, the hydraulic load of waste water treatment plants increases with additional retention storage. This might decrease the treatment efficiency and thereby decrease the benefit of stormwater storage tanks. The dynamic dependence between transport, storage and treatment is usually not taken into account. This dependence must be accounted for when planning treatment plants and calculating storage capacities in order to minimize the total pollution load to the receiving waters. A numerical model will be described that enables the BOD discharges to be continuously calculated. The pollutant transport process within the networks and the purification process within the treatment plants are simulated. The results of the simulation illustrate; a statistical balance of the efficiency of stormwater tanks with the treatment plant capacity and to optimize the volume of storm water tanks and the operation of combined sewer systems and treatment plants.
