A storm drain, storm sewer (U.S.), stormwater drain (Australia and New Zealand) or drainage well system (UK) or simply a drain or drain system is designed to drain excess rain and ground water from paved streets, parking lots, sidewalks, and roofs. Continue reading the full ...
Urban stormwater is regarded as a key input of faecal contamination in receiving water bodies and therefore, a major concern for health risks associated with aquatic recreation. Wastewater leakages, cross connections and overflows, together with faeces washed from surfaces during rainfall events, are possible origins of faecal contamination which enter these water bodies through stormwater ...
Microplastics seen washing into a waterway from a manufacturing plant's stormwater drain has been called totally unacceptable by the local board chair Waste from a plastic tank manufacturer was seen washing into a waterway that feeds into Auckland's Manukau Harbour. The Wiri-based company, Bailey Tanks, has previously been fined $750 for discharging polyethylene granules to land. Local Shaun ...
Stormwater runoff is a major cause of water pollution in urban areas. When rain falls on roofs, streets, and parking lots, the water cannot soak into the ground. In most urban areas, stormwater is drained through engineered collection systems and discharged into nearby waterbodies. The stormwater carries trash, bacteria, heavy metals, and other pollutants from the urban landscape, degrading the ...
Catchbasins (also known as gully pot in the UK and Australia) are used to receive surface runoff and drain the stormwater into storm sewers. The recent interest in catchbasins is to improve their effectiveness in removing sediments in stormwater. An experimental study was conducted to examine the hydraulic features and sediment capture efficiency in catchbasins, with and without a bottom ...
The development of a continuous model to simulate the behaviour of sewer systems requires detailed information on each component of the flows contributing to the global discharge. In this paper authors investigate a novel method based on signal processing and long time series data implemented with a 2 min time step (flow rate, conductivity, pH and turbidity) in order to identify the dry weather ...
Untitled Document BLOBEL manufactures and supplies manual and automatic Retention Barriers, Stormwater Drain Covers and Flood Protection Systems. The Retention Systems have a wide range of applications and are currently being used in the following three key areas: Spill Control, Containment of Contaminated Fire Fighting Water and ...
Roorkee, a sub-tropical urban town in India, has shown a rapid unplanned growth in the past. This paper presents the findings of a study of characteristics of urban soil, rainwater, and runoff emanating from different sources areas and the stormwater flows in the drains. Urban soil showed significant increase in the concentration of all constituents in comparison to the nearby rural soil. Soil ...
Storm water is the result of rain or snow melt that collects in an area that can drain from into a nearby body of waters such as a lake or river. The water can collect on roof tops, parking lots, saturated ground, roads, etc. The problem is that many of the pollutants of our modern living such as oil, grease, pesticides, sediment, salt, and animal waste are washed away within the storm water and ...
In today’s business environment it is vital to install effective risk management strategies. The manual and automatic Doorway Spill Barriers, Water Barriers, Stormwater Drain Covers and Flood Protection Systems BLOBEL manufactures, respond to this need. BLOBEL Spill Barrier and Flood Control Systems have a wide range of application. The Containment Systems can be used for Spill Control, Sprinkler ...
This paper describes the planning, design and construction of a permeable pavement as a practical demonstration of the benefits of eco-paving in Australian environmental management. The paper addresses the use of permeable pavements as part of a Water Sensitive Urban Design that allows infiltration of stormwater, reduction of pollutants and slow reticulation of the stormwater to an ecologically ...
Global land use patterns and increasing pressures on water resources demand creative urban stormwater management. Strategies encouraging infiltration can enhance groundwater recharge and water quality. Urban subsoils are often relatively impermeable, and the construction of many stormwater detention best management practices (D-BMPs) exacerbates this condition. Root paths can act as conduits for ...
In 2016, the nine-year old BMO Field in Toronto, home of the Toronto FC, also became home to the Toronto Argonauts, and a $120 million investment to expand seating began. As tough as Argo fans are, it was decided to add two large steel canopies above the bleachers to protect them from the rain and snow that are often part of football season. And because rain and melting snow have to go somewhere ...
Problem: Worldwide, Reichhold Chemical Corp. produces some 5600 products. At St. Helens, Ore., they produce three -urea, ammonium nitrate and ammonia. Plant drain water is discharged into the Columbia River, and although oily residues are minuscule because of a concerted program to keep oil off the floors, some is present - drippage from ammonia compressors, vehicles and machine maintenance ...

Many municipalities have vast areas of developed impervious acreage from which stormwater drains without any form of treatment. These drainage systems were designed decades ago, predating regulatory requirement for nonpoint source pollution control. Every year pollutants from these sites discharge high levels of sediment, nutrients, trash, and heavy metals into local waters, impairing usage, ...
Oil water separators (OWS) can be co$tly to maintain, $20,000 or more on average per cleaning and if not properly managed, can be very expensive conduits of pollution. Have you taken steps to minimize the effects and consequences on your operating co$t? When was your facility’s last OWS maintenance performed? Is your employee’s attitude, don’t worry we have an Oil Water ...
How do you clean a stormwater management pond (SMWP) without draining the pond first? A clean-out of the SWMP is required once every 5-15 years to remove accumulated sediments to ensure the pond continues to function as intended. Drainage of the SWMP is not always required to facilitate the clean-out. By combining the pumping and excavation into one process! New pumping technology - Dragflow ...
A SEEMINGLY simple kid’s prank of throwing rocks and other material down a storm drain resulted in a major emergency repair job to prevent the collapse of a 42-in. sanitary sewer main in Spokane, Washington. In a short period of time, a group of kids completely blocked an 18-in. pipe leading to the city’s combined sanitary/ storm drain system. The drain soon began to overflow, ...
