Use of compost filter bermsfor sediment trapping: primary focus on water quality and structural stabilityRaut Desai, Aditya Babu 15 November 2004 (has links)
Runoff from road construction and maintenance sites is responsible for erosion and deposition of sediments in the receiving water bodies. In addition to soil particles from erosion, runoff also transports other pollutants such as rubber, toxic metals, automobile fluids, car exhausts (which settle with the rain), pesticides, fertilizers, and other debris. Compost has been used effectively as a valuable soil amendment to aid plant growth. Berms (mounds) of compost placed at the top or bottom of steep slopes can be used to slow the velocity of water and provide additional protection for receiving waters. However, a downside of the application of composted organic material is the potential degradation of runoff water quality. Overloading with nitrogen and phosphorus causes eutrophication, which reduces the suitability of waterways for beneficial uses. A field testing of the berms coupled with a laboratory analysis of the testing water will provide a basis for the impact of the compost berms on the runoff water quality. The study of the impact of compost on the runoff water quality was investigated. The objective of this study was to evaluate the performance of berms made from various materials such as dairy manure compost, yard waste compost and composted bio-solids mixed with wood chips in a ratio of 50:50 on the runoff water quality, as well as, the sediment removal efficiencies. Field tests were performed on the berms to simulate conventional rainfall runoff and the tested water was collected as time-weighted samples and analyzed in the laboratory. Several variables were investigated during this study. Results of this investigation demonstrated that the effectiveness of this application was hampered by the structural instability of the berm. A 100% failure rate was observed in the berms tested. Optimum performance was observed in yard waste compost berms, which introduced the least amount of contaminants into the water. However, some masking effect could be present due to berm failures. In fact, the actual sediment removal by the berms could not be determined. The study of compost filter berms showed some evidence of the existence of first flush effect.

Amenity in Sustainable Stormwater: A Preliminary Assessment of the Toronto Green StandardKalvins, Eriks 09 May 2012 (has links)
Stormwater management systems reduce the impact of surface runoff in urban environments. The Toronto Green Standard (TGS) has been developed to further mitigate effects of urban runoff by mandating runoff control implementation in new developments at the site level. The intended effect of these measures is to reduce the quantity and improve the quality of water. Recent concepts of sustainable stormwater suggest that amenity is an equally important aspect of such a system. This study evaluated Best Management Practices suggested by the TGS for their performance and amenity characteristics. Design professionals selected for prior experience with the TGS were consulted to determine industry perceptions of the requirements, and how the standards could be altered to improve amenity value. Several concerns were identified which appear to impede the successful implementation of sustainable stormwater management solutions, to which recommendations are proposed which may help balance performance and amenity requirements in the TGS.

Design of Logan City's Stormwater Conveyance SystemBeck, Kade Jacob 01 April 2017 (has links)
Logan City is located in northern Utah's Cache County. The average annual rainfall for Cache Valley is between 15 and 20 inches (PRISM 2016). Several times a year, the incomplete storm water system causes flooding, which risks industrial and agricultural lands. The current system collects storm water between 200 West and 1000 West, and discharges the water directly along 1000 West.
Cutler Reservoir, Swift Slough, and the Lower Bear River in Cache Valley do not comply with water quality regulations. The Clean Water Act of 1972 mandates that all municipal separate storm sewer systems (MS4) comply with EPA regulations, expressed as Total Maximum Daily Loads (TMDLs). Logan City's untreated storm water might contribute to the pollution in these water bodies. The pollution threatens surface water, groundwater, and wildlife in the area.
Logan City plans to implement a new wastewater treatment process. However, the new treatment process is not designed to use the existing polishing ponds. Consequently, Logan City hopes to use these polishing ponds to treat storm water.
The implementation of this design improves storm water management. 10th West Engineers (10WE) had three goals. First, design a system to transport water form the discharge locations to the holding pond. Second, design a system that provides irrigation users access to water during a storm. Third, comply with the goals of the client: design a gravity-fed system, minimize effect on wetlands, and produce an economical design.
