This article identifies the 4 groups who need to be contacted, to promote A-lok watertight connectors for sanitary and stormwater contaiment systems ,in areas through out the world where they are presently not in use.
Stormwater Management Improvements Spurred by Low Impact Development Techniques
Abstract A concept first advanced in 19901, evidence of Low Impact Development (LID) can now be seen across North America. Like many infrastructure transformations, this growth in LID design has benefitted from regulatory changes; compliance versus cost remains an important motivator in any commercial venture. Through their efforts, LID pioneers have demonstrated a range of social and aesthetic benefits that have complimented the economics of this approach. Municipalities across the country are leading the...
WaStop chosen to protect Forest View residents and property from flooding - Case Study
Location: Forest View Customer: The Village of Forest View Problem: Originally Forest View had a combined sewer and stormwater system. As the area became popular development occurred which lead to more hard surface areas, which lead to higher runoff during rainy periods. This became such a problem that, in the 1960’s the sewer and stormwater system was split to ensure that high rainfall events didn’t overload the sewer system causing backflow into residential properties. The two split systems...
Bioswales reduce contaminants associated with toxicity in urban stormwater
Contamination and toxicity associated with urban stormwater runoff are a growing concern because of the potential for receiving system impacts. California water regulators are mandating implementation of green infrastructure as part of new urban development projects to treat stormwater and increase infiltration. Parking lot bioswales are low impact development practices that promote filtering of runoff through plants and soil. Studies have demonstrated that bioswales reduce concentrations of suspended sediments,...
Understanding the factors influencing the removal of heavy metals in urban stormwater runoff
In this research, an infiltration trench equipped with an extensive pretreatment and filter bed consisting of woodchip, sand and gravel was utilized as a low impact development technique to manage stormwater runoff from a highly impervious road with particular emphasis on heavy metal removal. Findings revealed that the major factors influencing the removal of heavy metals were the concentration of the particulate matters and heavy metals in runoff, runoff volume and flow rates. The reduction of heavy metals was...
Monitoring fuels in Stormwater - Case study
The SituationA major pipeline company has large storage tank farms throughout the Western States. The pipeline company transports, stores, blends additives, and distributes gasoline, diesel, and jet fuel to retail service stations and airports. Due to the quantity and movement of fuel at these facilities, there is always the potential for fuel spills. These facilities prevent out of compliance discharge by capturing all stormwater in storm drains, which is then sent to treatment systems prior to discharge. At...
