Dry-Weather Metals and Bacteria Loading in an Arid, Urban Watershed: Ballona Creek, California

Dry-season urban runoff from watersheds in arid regions can contribute substantial concentrations and loads of bacteria and metals to downstream receiving waters. However, there are few studies that have evaluated the relative contributions of different sources of these constituents along a specific creek or channel. This study involved analysis of the relative contribution of various storm drain ...

Latah creek sanitary sewer main repair, Spokane, Washington - Case Study

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, ...

Safe Drain® Saves My Facility From Accidental Spill

"I am writing to thank-you for a great product. This morning we had a 25 gallon diesel spill near our Vehicle Service Area. The spill was a fluke - from the tank of a truck that was parked on a gradient - left without a gas cap. Diesel poured out of the truck onto the asphalt - directly into a newly installed Spill Safe Drain that was closed tightly. All of the spilled product was recovered, ...

Hydrogen sulfide removal from sediment and water in box culverts/storm drains by iron-based granules

A renewable granular iron-based technology for hydrogen sulfide removal from sediment and water in box culverts and storm drains is discussed. Iron granules, including granular ferric hydroxide (GFH), granular ferric oxide (GFO) and rusted waste iron crusts (RWIC) embedded in the sediment phase removed aqueous hydrogen sulfide formed from sedimentary biological sulfate reduction. The exhausted ...

An Investigation into the Water Quality of the Charleston Peninsula Storm Drains

Since the late 1980’s, the South Carolina Department of Health and Environmental Control (SCDHEC) has expressed concern over extremely high fecal coliform counts found in several of the many storm drains that discharge from peninsular Charleston (City of Charleston, 1998). Although the City of Charleston is responsible for the fifty-plus storm drains, Charleston Water System wants to determine if ...

Modeling of coastal water contamination in Fortaleza (Northeastern Brazil)

An important tool in environmental management projects and studies due to the complexity of environmental systems, environmental modeling makes it possible to integrate many variables and processes, thereby providing a dynamic view of systems. In this study the bacteriological quality of the coastal waters of Fortaleza (a state capital in Northeastern Brazil) was modeled considering multiple ...

How To Avoid Penalties For Not Containing Spills

"Chemical spills can cost your company millions of dollars not to mention the bad publicity that results from suffering a spill. Every business wants to avoid the possibility of an uncontained hazardous material spill if at all possible. To do this you need a spill containment system designed for the type of hazardous materials that your handle. Safe Drain provides an innovative ...

Master Plan of Drainage for Redlands - Using advanced storm drain modeling techniques to identify historical flooding issues - Case Study

The city of Redlands, California, has a long history of flooding during moderate to severe storm events. The historic downtown area resides just downstream of the confluence of four major tributaries. The four tributaries run into a single storm drain under Redlands Boulevard, which routes flows through the downtown. The existing capacity of the current facility is approximately 2,000 cu ft per ...

Diffuse pollution

Diffuse Pollution or Nonpoint source (NPS) pollution is water pollution affecting a water body from diffuse sources, such as polluted runoff from agricultural areas draining into a river, or wind-borne debris blowing out to sea. Nonpoint source pollution can be contrasted with point source pollution, where discharges occur to a body of water at a single location, such as discharges from a ...

Sanimax Quebec, Canada - Case Study

Sanimax is a fat rending facility. One of the oil tanks overflowed during a power shutdown. Attempts to contain the spill were made using sorbents. Due to the large amount of spilled oil the containment effort yielded partial success. The oil flowed into a storm drain and within minutes reached a nearby river. Costly cleanup operations were ...

Challenges of Modeling a Tidal Influence Conveyance System, a Seattle, Washington Case Study

Hydraulic modeling of a drainage basin usually involves system representation of a network that flows either by gravity downhill or a force main via an outfall to a receiving water body or a treatment plant. And calibration of such a system is usually straight forward. Occasionally, engineers encounter a “City of New Orleans” type of conveyance system, where most of the storm drain network is ...

Hydraulics characteristics of tipping sediment flushing gate

This paper highlights a preliminary study on the potential of a tipping flush gate to be used in an open storm drain to remove sediment. The investigation was carried out by using a plasboard model of the tipping flush gate installed in a rectangular flume. A steady flow experiment was carried out to determine the discharge coefficients and also the outflow relationship of the tipping flush ...

Corrosion-Resistant PVC Sends Metal Pipe Down the Drain Case Study

Drain, Waste and Vent (DWV) systems are necessary in every building for removing sewage and storm water from a variety of fixtures and regulating air pressure to facilitate flow. Pipes used in traditional DWV systems for commercial buildings due to code restrictions have long been made of copper and heavy cast iron. However, performance has often been an issue knowing that sanitary and storm ...

Unique sponge system contains water contaminants in storm drains

Untitled Document SmartSponge technology captures oil and hydrocarbons from stormwater runoff, preventing its discharge into receiving waters. Water quality is being bolstered in dozens of locations around the United States through the use of a rather simple system. The concept is simple – a polymer “sponge” that removes contaminants from water before it winds up passing ...

July is Lake & Reservoir Awareness Month!

Lakes and reservoirs cover over 40 million acres of the United States. Lakes and reservoirs also play other vital and often hidden, roles. They provide drinking water and irrigation water for agricultural fields and many times a source of electricity and power generation. They also serve an important function of absorbing rainfall and runoff from land, help to prevent floods, and provide homes ...

Amplification of Indicator Bacteria in Organic Debris on Southern California Beaches

INTRODUCTION Certain recreational beaches in southern California frequently exceed state water quality standards for indicator bacteria (total coliform, fecal coliform, and enterococcus). In San Diego County, two sites have been particularly problematic: Mission Bay, a large coastal embayment; and Dog Beach at the mouth of the San Diego River. Recent studies designed to investigate sources ...

The Amplification of Indicator Bacteria Occurring as a Result of Kelp Mound Incubation Along a Protected Beach in Southern California

ABSTRACT Pacific Beach Point (PB Point) in La Jolla, CA, has frequently exceeded state water quality standards for indicator bacteria. As a result, studies were designed to investigate bacterial transport mechanisms and possible bacterial amplification occurring within the extensive kelp mounds found along the beach wrack line. Investigations thus far have shown that the wrack line acts as a ...
