Using Concrete Safety Barriers in Traffic Management

When we think about car accidents most people think about an impact with another vehicle or veering off the road into a building or tree. In newer cars and trucks the driver and passengers are surrounded by a range of safety features including seatbelts, airbags and even safety sensors that slow the car down when an obstruction is detected. But pedestrians don’t have built in airbags or sensors.

Vicroads statistics show that on average 690 pedestrians were seriously injured and 47 pedestrians are killed getting hit on Victorian roads each year. In New South Wales these statistics are even higher with 1522 pedestrians seriously injured and around 50 killed each year according to Transport for New South Wales.

The automotive industry is making leaps and bounds towards smarter vehicles detecting obstructions before an accident happens, but we are years off this being perfected and even further off from this becoming affordable to everyone on our roads. So, in the meantime we need to improve our road safety through well thought out traffic management.

But how can effective traffic management decrease the chances of an accident?  Decreasing speed limits in high pedestrian areas and increasing speeding fines can deter drivers from risky driving behaviours. However, concrete barriers provide a physical blockade between people and drivers.

 

Uses of Concrete Barriers

During any scenario involving moving vehicles the safety of people is a number one priority. In many situations there is an increased risk of out-of-control vehicles including winding roads along the coastline, or high anxiety areas such as inner city driving or fast-moving highways. These higher risk driving situations create the potential for a driver to enter pedestrian or hazardous areas. That’s where concrete safety barriers can help ensure the safety of people in the area or that you and your car don’t end up around a tree or over a cliff.

Concrete barriers are installed to mitigate the risk of vehicle misdirection or impact in the situation that a driver loses control in a high-risk area. With the intention of halting or redirecting a vehicle when impact occurs, this lowers the chance of collision with people, oncoming traffic or other hazards.

 

Different Uses of Concrete Barriers

Although concrete barriers are primarily designed to provide safety on our roads, there are actually a few situations that safety barriers can be utilised in; traffic management, event management, road construction safety and in a lot of cases safety barriers can be a permanent installation.

 

Traffic Management

There are a variety of reasons we would need to redirect traffic. Whether a road is closed for some much-needed maintenance or a special event, concrete barriers are the best option. Providing a sturdy barricade will be a strong deterrent to anyone wanting to drive into areas they are not allowed. Traffic management doesn’t only refer to vehicles either, foot traffic is still traffic. Road barriers can be used to redirect pedestrians in unsafe locations.

 

Event Management

Large scale events can sometimes require a road closure or have temporary concrete barriers along the street to prevent vehicle access to footpaths or crossings. Concrete safety barriers can also be installed at each intersection to prevent any vehicle traffic entering the road entirely.

This works both ways though, preventing people from entering the street during high-speed events. This safety concern has become increasingly common in events such as competitive cycling or marathons.

 

Roadside Construction Safety

In the instance that work is being carried out on a roadside, this is considered a workplace and in turn OHS practices need to be followed. These safety policies and procedures help to decrease chances of injury not only for staff on site, but also any pedestrians that may be in the area. Using a combination of concrete barriers and no-go zones provide workers with a safer work environment to complete crucial road maintenance.

 

Permanent Installation

High risk areas such as coastal roads on cliff faces or highways may opt to install permanent safety barriers or as an alternative, noisewalls can also redirect traffic. An audit conducted by Vicroads in 2019 found that highways with permanent road safety barriers installed had 46.5% less accidents resulting in fatalities or serious injury.

 

Different Types of Concrete Barriers

At Civilmart we produce concrete road barriers in 3 different styles; all are 805mm high and 600mm wide, however are available in 3m or 6m lengths. Our 6 metre lengths are available as either a standard length or a terminating barrier designed as an end to a row of barriers.

Each barrier includes two 5 tonne lifting points and drainage to release any rainwater than may build up in the zoned off area. We can also produce barriers without the drainage if this is what your project requires.

For an installation with 2 or more barriers joining plates will be required to lock each barrier unit together.

 

What is a Longitudinal Channelising Device and how is different from a safety barrier?

On the market there is a similar product that is often confused with a road safety barrier. Typically made of plastic materials longitudinal channelising devices are used to redirect foot traffic. Being used along footpaths in construction areas these devices are designed to direct pedestrians through the safest path. Although these devices are similar in design to safety barriers, they do not have the weight or engineering required to obstruct a vehicle in an accident.

Sourcing Concrete Barriers through an Equipment Hire Company

For temporary usage it may seem a bit frivolous to purchase concrete barriers. Luckily there are plenty of businesses that specialise in hiring out traffic management equipment. All across Australia you can find companies that deliver and install road safety barriers including; RSEA or Coates Hire who both have sites located all over the country!

How Wastewater Treatment Plants Work

How Wastewater Treatment Plants Work

As Australians we love our water. Whether it’s a nice hot shower at the end of a freezing winters day, or to cool down in the pool during summer. Our households use thousands of litres of water every week. In fact, in 2021 the average Melbournian used an average of 162 litres per day! That’s a lot of water!

But how can we decrease our water use? We can cut down on laundry. We can water our gardens less often. Or we can install a domestic wastewater system and take advantage of using clean effluent (processed wastewater) to do a lot of our everyday activities that require water.

Let’s take a few minutes to explore the ins and outs of these revolutionary treatment systems.

 

What Is A Domestic Wastewater System?

A domestic wastewater treatment plant, such as Civilmart’s SuperTreat Queensland, is a setup designed to recycle and reuse the water from our households or businesses.

Typically manufactured as precast concrete unit, the system is designed for your wastewater to travel through multiple chambers to complete a treatment process.

The goal of the treatment plant is to convert wastewater and greywater created in our showers, kitchen sinks, washing machines, dishwashers, baths and even our toilets into a more environmentally friendly effluent. That means we can use that water again to irrigate our gardens, or even pump that water back through our laundries and toilet systems.

 

Benefits of a Domestic Treatment Wastewater System

We all try our best to savour our limited resources. We save money that we’ve worked hard to earn. We save time by finding more efficient ways of completing our work. But being able to go to our kitchen or bathroom and have running water makes us often forget that water is also a limited resource.

Installing a wastewater treatment plant is an environmentally conscious method of repurposing and reducing your water usage. The process utilises naturally occurring anaerobic (oxygen thriving) bacteria to breakdown contaminants in the wastewater. This also means we can avoid the use of nasty chemicals.

An additional benefit to the treatment plant is they are normally installed underground near your home. This means no unsightly tank becoming an eyesore in your backyard!

 

When Do You Need A Domestic Wastewater System?

A large portion of the Australian population is connected to a mains water supply, but not everyone. In the case that you aren’t connected to the mains network, you will require a sewage system to manage your waste.

In this case you would have few options available because you’re definitely not going to want to live without a sewage system!

Many rural properties have septic tanks installed to deal with their sewage, however the most modern and efficient option is a domestic wastewater treatment plant. Each year more and more Australian’s are opting to install wastewater treatment systems as a more environmentally friendly alternative.

 

Domestic Wastewater System vs Septic Tank?

It’s a common misconception that wastewater treatment plants and septic tanks are the same. However, there are some key factors that make these two very distinct products.

The by-product of a septic tank is a strong pollutant that needs to be disposed of through a combination of desludging and secondary treatment. This secondary treatment could be a sand filter system, which requires a large portion of land to filtrate the poor effluent produced. And after a few years the sand system will also become highly toxic and need to be professionally disposed of.

Alternatively, there is an aerated wastewater treatment plant, which requires a second tank to be installed alongside your septic, taking up additional space and carrying a hefty price-tag.

A typical domestic wastewater treatment plant collects and treats your waste all in one place. There’s no need for a secondary system to ensure your effluent is clean!

 

What Are The Stages of Wastewater Treatment?

As there are many manufacturers and suppliers for treatment plants, there are a few different ways yours might work. But let’s look at the process of Civilmart’s TurboJet Single.

Stage One

Wastewater from your home flows into the primary chamber. At this stage the liquid and solid matter in your waste are separated. Solid matter will sink to the bottom on the chamber allowing only liquid to raise to the top of the system.

Stage Two

The liquid held near the top of the primary chamber will then flow into the secondary chamber. This is an additional stage where any remaining solid matter should sink to the bottom of the tank.

Stage Three

In the aeration chamber the water is treated with a combination of oxygen and anaerobic bacteria to break down any pollutants and reoxygenate the effluent. There is also a biological media sheet that captures and dissipates any toxic bacteria or algae that may be remaining after the aeration process. After your wastewater has been through the aeration process the remaining liquid should be visibly clear.

Stage Four

The fourth chamber is quite similar to the primary and secondary chambers. At this stage there should be little to no remaining solid matter, however, to ensure a clean effluent, any traces of solid matter will again sink to the bottom of the treatment system. From here any remaining pollutants will be processed back into the primary chamber for when the system needs to be pumped clean.

Stage Five

To complete the final stage of the treatment process the wastewater will enter the pump-out chamber. In this chamber the water is pumped through a chlorinator and disinfector unit to clean out any remaining bacteria. The now clean water is pumped out from the treatment plant to be used in your irrigation.
