When do floating baffles improve performance in sediment basins or stormwater treatment ponds? In sediment basins on construction or disturbed land, high-velocity inflows often rush straight to the outlet, leaving much of the basin “unused” and reducing capture of fine sediment (Rivers & McLaughlin 2015). Floating or suspended baffles can (Rivers & McLaughlin ...
Management of the quantity and quality of urban stormwater run-off is a major concern for government authorities. The increase in impervious surfaces associated with urbanisation of catchments results in an increase in the volumes of stormwater runoff that must be handled by the stormwater drainage systems and a consequent ...
The National Water Quality Management Strategy (NWQMS) is the body through which water quality standards are developed in Australia. ...
Phil Riise worries about every single particle of pollution that washes from his waterfront business, Seaview Boatyard North, into Bellingham Bay. It’s partly because he cares about the body of water, where he fishes and crabs for sport. But it’s also because just a little too much pollution could take a large financial toll on his livelihood - boatyards that don’t meet state ...
July 15th, 2020 Martin County and EcoSense International have partnered to reduce excess nutrient concentrations at a local level. EcoSense specializes in nutrient removal. The joint initiative involves lowering nutrient levels in MacArthur Lake to minimize algal blooms. This effort involves 64 independent buoys supporting permeable bags filled with a special formulation of NutriGone™ and ...
Patrick Chavez, AMFACA’s Stormwater Quality Program Engineer, is responsible for developing and maintaining the Agency’s Stormwater Monitoring Program (SWMP). ...
Cities, counties, and municipalities are increasingly encouraging—if not requiring—the adoption of green/sustainable BMPs, including stormwater management and low impact development (LID) strategies as outlined by the US Green Building Council's (USGBC) Leadership in Energy and Environmental Design (LEED) rating system. ...
Our grandparents focused their lives on making sure they had enough to live; our parents had the chance to start their lives with not much, and grow into a more and more comfortable life; we’re lucky to have been born to a comfortable life, but grew up realising we can’t just overuse natural resources, we need to protect them; our kids talk about their commitment to use less ...
We measured pollutant removal efficiency and compared growth and nutrient uptake of five macrophytes in demonstration scale units (volume >40 m3) irrigated by water with pollutant concentrations representative of average urban stormwater quality. All species showed a strong productivity gradient along the beds, starting with high biomass – high density near ...
Safe drinking water is going scarce all around the world for the growing population and pollution! Increased rates of water usage in industrial as well as residential areas are the specific reasons behind this. Billions of people are away from easy access to safe drinking water. Apart from this, water borne illness has turned as one of the leading cause for growing the death rates. Lack of clean ...
Characterising stormwater runoff quality provides useful insights into the dynamics of pollutant generation and wash off rates. These can be used to prioritise stormwater management strategies. This study examined the effects of a low intensity rainfall climate on zinc contributions from different impermeable urban surface types. ...
Implications of three sewer pipe materials (concrete, galvanized corrugated steel, and polyvinyl chloride (PVC)) for stormwater quality were explored in laboratory experiments, in which three types of stormwater, SW1–SW3, were circulated in 0.5 m long sewer pipe sections. SW1 and SW2 represented synthetic rainwater, without and with fine ...
Aging wastewater collection and treatment systems have not received as much attention as other forms of infrastructure, even though they are vital to public health, economic growth, and environmental quality. Inflow and infiltration (I&I) are among potentially widespread problems facing central sewage collection and treatment systems, posing risks of sanitary system overflows (SSOs), ...
Certified Professional in Storm Water Quality (CPSWQ). The CPSWQ designation provides evidence of qualifications in stormwater management principles and methods. CPSWQ certification is available to those who have the education and demonstrated experience and expertise in computing, analyzing, and evaluating stormwater quality. ...
An investigation on free water surface wetland, which has an area of 0.23 ha and is employed to control the non-point source pollution from a watershed of 7.4 ha, was carried out to examine how the WQvr (the ratio of stormwater inflow volume to water quality volume (WQv)) affects the wetland treatment performance. As stormwater went through ...
The photo-degradation of nutrients in stormwater in photocatalytic reactor wet detention pond using nano titanium dioxide (TiO2) in concrete was investigated in a scale model as a new stormwater treatment method. ...
Bioretention systems are designed to treat stormwater and provide attenuated drainage between storms. Bioretention has shown great potential at reducing the volume and improving the quality of stormwater. ...
Customer Benefits Suitable for all quality types of wastewater, stormwater and raw water Lethal to different bacteria, fungi and virus - without any reactivation Non-halogen Non restricted by high concentration of suspended solids or iron content Very simply and quickly applicable, with low investment cost ...
This paper investigates the water quality characteristics of rainwater runoff from dual-substrate-layer green roofs in Tianjin, China. The data were collected from four different assemblies and three types of simulated rains. The storm-water runoff quality was monitored from early June through late October 2012 and from July through late November 2013. The results revealed that the runoff water ...
Stormwater runoff quality is sensitive to land use and land cover (LULC) change. ...
