Wastewater
At SafeRack, we understand the critical importance of optimizing safety and efficiency in these high-risk environments.
Wastewater treatment facilities require customized access and safety solutions due to the diverse nature of the water being treated, facility size, and environmental factors. Our innovative platforms, gangways, and spill containment systems are engineered to meet the stringent safety and operational needs of wastewater treatment plants, ensuring compliance and protecting workers from hazardous conditions. Explore our range of solutions tailored to the unique challenges of wastewater management.
No two wastewater treatment plant (WWTP) safe access solutions are identical as the type of water being treated, facility size, and climate greatly affects the critical design criteria that will ensure that optimum safety and productivity can work together in harmony.
Wastewater is used water. It includes substances such as human waste, food scraps, oils, soaps, and chemicals. In homes, this includes water from sinks, showers, bathtubs, toilets, washing machines, and dishwashers. Businesses and industries also contribute their share of used water that must be cleaned. Containment of industrial spills must be in place and they must be armed with an emergency spill response plan in case something goes wrong. Like when an Alabama food company caused a massive fish kill and threatened residents with health issues because of their oversight, EPA could issue stiff penalties for Clean Water Act violations amounting up to $2 million.
We consider wastewater treatment as a water use because it is so interconnected with the other uses of water. Much of the water used by homes, industries, and businesses must be treated before it is released back to the environment.
If the term “wastewater treatment” is confusing to you, you might think of it as “sewage treatment.” Nature has an amazing ability to cope with small amounts of water wastes and pollution, but it would be overwhelmed if we didn’t treat the billions of gallons of wastewater and sewage produced every day before releasing it back to the environment. Treatment plants reduce pollutants in wastewater to a level nature can handle.
Products
WWTP Solutions
Below are some of the loading and unloading solutions for illustrative purposes only. Our experts will work with you and your team for a custom solution to suit your needs.
Loading Gangways
24″ Self-adjusting access gangways are required to safely access the varying-height trucks transporting chemicals and waste products. Durable marine-grade aluminum and stainless steel options provide years of maintenance and corrosion-resistant service. Powered gangway solutions are also an option, with both hydraulic and pneumatic solutions being commonly used.
Each gangway will have a four-rail safety cage for the tank truck hatch area. It creates a secure 4’x6′ barrier to falls while the operator (un)loads the product. These systems have engineered layouts to ensure safe access, and fall protection equipment works with the loading arms.
GX SELF-ADJUSTING STAIR (SAS) GANGWAY
SafeRack’s NEW GX SAS gangways use Retractalok power-assist technology, allowing operators to raise or lower effortlessly. They are light as a feather to lift and solid as a rock. Tested in the most critical applications, this revolutionary new gangway outperforms all others. They are available in multiple lengths and widths.
Loading Arms
Sludge is typically loaded into tank trucks via 6″ carbon steel loading arms. The current best loading practice includes a vapor plate or cone with a 2″ to 3″ vapor line. Many times wastewater treatment plants are located near populated areas where vapor and odor control is required to meet EPA standards.
The typical seal material for the loading arm swivel joints is PTFE, which is durable and chemical resistant.
These racks can also be designed to handle other chemicals used in water treatment facilities to meet EPA-mandated discharge permits, such as anti-foaming agents, pH neutralizers, coagulants, and flocculants.
Eye Wash/Drench Showers
ANSI guidelines state that an Eye Wash/Drench Showers need to be located 10 seconds or 55’ (16.8m) from contaminants or hazardous materials.
Eyewash stations need to be on the same horizontal plane with no obstructions.
Therefore, we propose installing a standard combination Drench Shower/Eyewash Unit, which will save limited space and fit easily into any work environment.
Spill Containment
Spill containment pans will be provided at the point of loading operations and are an essential piece of equipment in overall site safety and environmental protection.
Wheel chocks allow for safe access to and storage of treatment chemicals, while spill containment pans utilized at the point of loading operations serve as essential safety and environmental protection tools.
Piperacks
Because wastewater treatment plants have pipe runs throughout the facility, ErectaRack pipe racks are pre-fabricated for a variety of pipe dimensions and applications. Because they’re pre-engineered, ErectaRack skips the long engineering and fabrication process, saving weeks, if not months in the installation process.
Grounding
While not highly flammable, high airborne concentrations of certain products and chemicals can be ignited and pose a significant fire and explosion hazard, especially in confined spaces. Industry best practice includes the grounding of all vessels before starting the (un)loading process.
Vehicle grounding and bonding — ensure true grounding before product flow is permitted
Safety Gates, Stairs, Ladders, & Platforms
Safety Gates will be installed at the top of stairs and any other openings to ensure operator safety.
SafeRack’s line of industrial safety gates is the most flexible product on the market with the ability to span openings between 16” and 36” and is field adjustable with nothing more than a wrench. We also have guardrails, metal handrails, and full-fledged fall protection solutions with customizable options to fit your needs.
Loading Platform Options
Lighting – General exterior and task lighting to illuminate work and walk areas.
Platform & Canopies – Full platform canopies reduce exposure to the elements and improve the safe and productive loading operation from the operator’s perspective.
Operator Shelter—Depending on your site requirements, consider the requirement of an operator or guard building to keep personnel out of the elements. This can be customized to meet specific site requirements.
Wheel Chocks – SPCC options to allow for safe access and storage of water treatment chemicals.
10 Minute Tips: Wastewater Treatment Safety Reminders
Wastewater treatment plants are among the most hazardous places to work. In addition to navigating risks associated with heavy equipment, workers are regularly at risk for slips and falls, as well as exposure to toxic chemicals and other chemicals. These hazards can result in everything from minor injuries and serious illnesses, to blindness and even death. With these hazards in mind, it is critical for wastewater treatment plants to implement comprehensive strategies to promote, ensure, and maintain safety.
Here are the five main areas of concern regarding water treatment facility safety:
Floor and Platform
Hazard Prevention
The enormous amount of water involved in the treatment process makes slips, trips, and falls the leading hazards for wastewater treatment workers. These incidents can lead to everything from sprains and strains to scrapes and fractures — and worse.
In order to decrease the chances of any slips, trips, or falls, it’s important to identify and mark any areas that are prone to excessive water and puddling. Fix all leaks promptly, and be sure to sweep up or squeegee any puddles. Use non-slip flooring surfaces, traction tape, and require all employees to wear shoes with non-slip soles. Workers should also consider wearing fall protection gear.
You can further enhance your facility’s floor and platform safety with the following equipment:
- General exterior and task lighting are helpful for illuminating work and walk areas.
- Operator/guard buildings and full platform canopies reduce workers’ exposure to the elements. Canopies also make loading safer and more productive for operators.
- Crossover helps your employees navigate piping, while work platforms give them access to mechanicals.
- Loading gangways let workers safely access the varying height trucks that typically transport chemicals and waste products. They can be fitted with safety cages that protect operators from falls during unloading.
Engulfment and/or
Drowning Prevention
The pools at your wastewater treatment plant are the last kind of pools anyone wants to fall into. Accidents can happen, however.
The non-slip measures mentioned above must be used around all vats on all catwalks. Guardrails should be installed around all open water sources, and all handrails should be strong enough to prevent falls.
When working in unguarded areas, employees should be monitored by coworkers. They must also wear fall protection when 6 feet (or more) above the ground or at a lower level.
Before lifting grates and loading ramps over waterways and tanks to allow employee access, block off the area, and place hazard warning signs. Keep rescue gear like flotation devices and hooks readily available near all tanks.
Confined-Space
Hazard Mitigation
Not designed for continuous work, confined spaces can pose serious safety concerns at treatment facilities.
Exposure to a low-oxygen environment or high levels of hydrogen sulfide, methane gas, or ammonia can result in serious illness or death. While not highly flammable, high airborne concentrations of certain products and chemicals can be ignited and pose a significant fire and explosion hazard, especially in confined spaces. Industry best practices include the grounding of all vessels prior to starting the (un)loading process.
Employees should follow OSHA requirements for restricted exit and entry regarding confined spaces. Warnings must be prominently displayed in all hazard zones, and barricades are recommended for preventing unauthorized access. Employees who access confined spaces should wear personal protective equipment (PPE) and ambient air and personal monitoring to ensure their safety.
Survey your entire facility for areas with limited egress and other hazard potential, as well as areas for explosion potential from flammable gas and water engulfment during heavy rain and flooding.
Equipment
Maintenance
Maintaining your machinery is mandatory, and should be done before there’s a problem. Doing so reduces the lost production time and safety hazards that can arise when your equipment malfunctions or breaks down.
Organization and planning are key when it comes to proper maintenance. Make sure all pipes and electrical systems are labeled properly, including intake and outlet pipes, as well as any equipment that can present an electrical flash hazard.
All employees performing repairs near live equipment must have the proper tools and protective gear and know how to use them.
Chemical and
Biohazard Handling
Chemicals and biological hazards pose some of the biggest threats to employee safety at your facility. Employees who aren’t protected from exposure can become ill.
Employees should wash hands frequently with antibacterial soap, making sure that any open cuts or abrasions are properly covered and protected. They should also change out of their work clothes before going home in order to avoid contamination.
Despite the best planning and procedures, accidents can still happen. With that in mind, no treatment facility should be without a standard combination drench shower/eyewash unit.
Safety data sheets (SDS) provide guidance regarding the properties, exposure limits, suggested PPE, and emergency actions for the treatment of chemicals in use.
When used with an oxidizer like hydrogen peroxide, the Ultra-S3 oxidizing system provides a cost-effective method of eliminating the smell emitted by hydrogen sulfide gas, keeping the gas at acceptable levels, and limiting the costly deterioration and corrosion it causes to facility infrastructure.
Effects of wastewater pollutants
If wastewater is not properly treated, then the environment and human health can be negatively impacted. These impacts can include harm to fish and wildlife populations, oxygen depletion, beach closures, aquifer contamination, and other restrictions on recreational water use, restrictions on fish and shellfish harvesting, and contamination of drinking water. Environment Canada provides some examples of pollutants that can be found in wastewater and the potentially harmful effects these substances can have on ecosystems and human health:
- Decaying organic matter and debris can use up the dissolved oxygen in a lake so fish and other aquatic biotas cannot survive;
- Excessive nutrients, such as phosphorus and nitrogen (including ammonia), can cause eutrophication, or over-fertilization of receiving waters, which can be toxic to aquatic organisms, promote excessive plant growth, reduce available oxygen, harm spawning grounds, alter habitat and lead to a decline in certain species;
- Chlorine compounds and inorganic chloramines can be toxic to aquatic invertebrates, algae, and fish;
- Bacteria, viruses, and disease-causing pathogens can pollute beaches and contaminate shellfish populations, leading to restrictions on human recreation, drinking water consumption, and shellfish consumption;
- Metals, such as mercury, lead, cadmium, chromium, and arsenic can have acute and chronic toxic effects on species.
- Other substances such as some pharmaceutical and personal care products, primarily entering the environment in wastewater effluents, may also pose threats to human health, aquatic life, and wildlife.
