4 Variables About Water Reclamation and Recycling to Consider

No matter what your politics are, ground water and surface water supplies are at risk of overuse in many areas. Future construction plans will need to account for all changing variable, and water reclamation and recycling are becoming more important because of upticks in

  • Demand of potable water resources
  • The cost of treating wastewater
  • Regulations requiring greater flows for streams and rivers, which reduces irrigation sources
  • Demand for sustainable building options.


Increase in Potable Water Demand

Regional development and migration have placed a strain on our water sources. Large populations in the US have migrated to warmer climates in California, Nevada, Arizona, Texas, and here in Florida. This exodus caused disproportionately affected growth rates from these states relative to the national population: 85 percent to more than 400 percent between 1970 and 2009 while the national population grew by less than 50 percent. Temperatures have also been trending higher and that is causing increases in evapotranspiration, the process of plants using water, thereby necessitating more irrigation for crops and landscaping. Water reclamation and recycling would be a consistent solution.

Cost of Water Reclamation

The concept of the true cost of water reclamation and recycling has been captured in the idea of the “triple bottom line,” which are the financial, social, and environmental impacts of a construction project. With a triple-bottom-line approach, the developer is considered to have an obligation to examine environmental and social impacts, in addition to profitability. The analysis performed in environmental impact reviews are consistent with triple-bottom-line thinking, although environmental review as an obligation summarily ends with project certification. In contrast, triple-bottom-line approaches call for ongoing review and analyses of financial, social, and environmental costs of a project, which are often summarized in annual reports. Triple-bottom-line accounting runs into the same challenges faced by economic valuation: the difficulty of valuing environmental and social impacts (Norman and MacDonald, 2004). This difficulty means that triple-bottom-line processes offer more guidance than quantitative comparative analysis, although the concept does alert business and public agency leaders that the public is aware of difficult-to-monetize impacts of their practices and the importance of striving for full accountability for new development impacts on society and the environment.


Everyone’s favorite topic. But the fact of the matter is, there is a growing rate of gastrointestinal infections in the United States and so the public concern over chemical contamination of public and private water supplies isn’t unreasonable. Due to limited resources and political gridlock, the ability of the public health sector and the research community to attribute disease to water consumption remains problematic. Determining the source of waterborne disease outbreaks is getting more difficult with the growing complexity of drinking water sources. At present moment, there is no national public health epidemiological research program committed to tracking endemic water-associated AGI community disease trends or comparative health impacts of differing water reuse patterns. Not only that, the capacity for public health officials to respond is anemic unless the disease reaches the point of endemic outbreak and emergency funds are available. As water reuse broadens in scope and volume, methods and expertise to determine whether AGIs are waterborne or whether community chronic health disparities are related to water reuse will be important to maintaining public acceptance of reuse practices and should be the focus of research partnerships.

Sustainable Building Demand

With dwindling natural resources and explosive population growth, the demand for sustainable building has been doubling every three years because recycled water can satisfy most water demands as long as it is adequately treated to ensure water quality appropriate for the use. Water reclamation is useful in minimizing impact of storm water on the Florida storm water system, while minimizing the use of potable water for maintenance and landscaping purposes by treating and recycling water. Reclaimed water can be used for just about any non-potable application including cooling water for power plants and oil refineries, industrial process water for such facilities as paper mills and carpet dyers, toilet flushing, dust control, construction activities, concrete mixing, and artificial lakes. Other reasons increasing the demand of sustainable building and water reclamation are providing a dependable, locally-controlled water supply, water recycling has incredible environmental benefits. By providing an additional source of water, water reclamation and recycling can help us find ways to decrease the diversion of water from sensitive ecosystems. The list of benefits continues as decreasing wastewater discharges and reducing and preventing pollution. Recycled water can also be used to create or enhance wetlands and riparian habitats. In short, the upside of water reclamation is indisputable, and ARC Development has decades of experience installing theses systems in our commercial development projects.

White Pavement Is Keeping Los Angeles Cooler During Heat Wave

During one of the most intense heat waves in Southern California this past week, residents are saying it’s not as bad as it used to be thanks to white pavement, or cool pavement, paving their streets. The experiment was initiated by Los Angeles City councilman Bob Blumenfield, whose constituency resides in the blazing hot southwest San Fernando valley, where temperatures regularly exceed 100 degrees.

What the city did was apply a light gray seal across a blistering half-block stretch of Jordan Avenue and the residents have noticed the cooler temperatures.

Since then, the battleship-gray reflective street surfaces have been added to short blocks in Arleta, Northridge and Hyde Park. Two more are slated to be laid down today in west Los Angeles, among 15 pilot projects across the city.

“It’s cooler,” said Jimenez, whose two daughters translated her Spanish comments outside their Jordon Villa apartment, where they’d set up a portable pool in temperatures that reached a high this week at 104 degrees. “The heat is not so bad.”

The goal of city officials with the white pavement is to reduce the road temperatures and cool the insides of the nearby buildings goal, as well as lessening air pollution and reducing the threat of deaths linked to increasingly hotter heat waves.

If this white pavement experiment is successful, the CoolSeal coating invented by GuardTop LLC could be added to thousands of miles of pending Los Angeles road upgrades.

In a city whose summer temperatures have risen an average 10 degrees in the past century because of increasing sprawls of asphalt, parking lots, roofs and more, Los Angeles city officials say the reflective white pavement roadways may help tone down the concrete baking expected to be get worse and worse.

The gray streets of white pavement could cost between $25,000 and $40,000 per mile and last five to seven years — a cost subject to change pending product and pavement innovation, city and GuardTop officials say.

After a week of blistering heat, a random test on the narrow street north of the Los Angeles River lined with two-story apartment buildings was conducted by three officials. Coincidentally, each arrived separately after the sun apexed on Thursday to measure the effectiveness of the white pavement coating applied May 20.

Patrick Carrigan, an assistant engineer for General Services, pointed a handheld laser thermometer at the gray surface darkened by a month of road grime. It read 138 degrees. He then aimed it at the unpainted crossroad at Hart Street and Jordan Avenue.

“See look at that: 149 degrees, an 11-degree difference,” said Carrigan, on his second visit to Jordan Avenue, which he tested in addition to the three other reflective road sites. “The total average spread is about a 10-degree difference between black-to-gray.”

Blumenfield got similar results, as did a GuardTop executive who dropped by later with another handheld thermometer. Each recorded slightly higher temperatures toward the middle of the gray-painted street stained dark by tires and other road residue.

Two years ago, the councilman had passed a motion to test a new cool pavement that, with more trees and reflective rooftop solar panels, he thought could counter longer and extreme heat waves.

After rigorous testing of the CoolSeal coating for durability and wet skid potential, it was first applied at a Sepulveda Basin parking lot. Summer surface temperatures fell from 20 to 25 degrees.

“It’s great,” said Blumenfield, a former state assemblyman who arrived in a gray suit, blue shirt and fuschia tie. “It’s forward-thinking … it’s a vision for a cooler San Fernando Valley, Canoga Park and Los Angeles.

“It means health … life and death for people. It’s not an academic exercise. If we lowered the temperature in this community, it would mean cost savings for everyone inside and out.”

Among the rows of aging apartments with names like Jordan Villa, Jordan Casa and Jordan Terrace flanked by blooming magnolias or the occasional palm, residents said they already felt the cool.

“Now, it’s a few degrees cooler,” Jimenez said of her apartment. “We like it. If it wasn’t for this street, the heat wave would make my apartment hotter.”

“I feel a slight difference on the street and inside my apartment,” said Priscilla Corleto, 24, walking Gatsby, her small white Shih Tzu. “Without the AC, it seems cooler.

“It’s good. I like it. I think it’s a success.”

Florida could certainly stand to benefit from white pavement roads, as average yearly temperatures here have been increasing too. Innovation is about solving problems and it isn’t limited to technology. Old practices like paving roadways can evolve to lessen the impact of increasing temperatures amongst urban sprawl.


Despite Construction Labor Shortage, Sector Powers Florida Job Growth in 2017

A third of all new jobs created in the last year in Florida occurred within the construction sector. Florida has enjoyed  robust economic resurgence that’s been a windfall to the construction companies. So much so that construction companies are experiencing a labor shortage to meet demand.

“Florida businesses have created 1.4 million jobs over the past six and a half years and our unemployment rate has dropped to the lowest in a decade, which is further proof that our efforts to cut taxes and grow the economy is helping our state become a national leader in job creation,” says Gov. Rick Scott.

The labor shortage for construction in Florida can be attributed to a variety of factors. During the shale and fracking boom, many skilled laborers left Florida and headed west. Many workers are aging and there aren’t young workers to take their place. A labor shortage means compensation rises, which in turn raises the cost and extends the completion time to build new developments.

Construction work in Florida isn’t for the faint of heart and the average age of an iron worker is 41. Lowering that age means more young people need to be trained, except it’s hard work and millennials as a generation are showing a predilection for seeking easier ways to earn a living. Until recently, the average age for new construction workers in Florida is about 28 years old,  which is 10 years removed from the times workers began training out of high school, except high schools don’t prepare kids for career using vocational or tradesman skills. Fewer high schools teach shop class and funding for vocational schools is all but gone. This has been caused by a ideological shift in education, where every kid is prepared for college, whether it suits their nature or not.

Sitting at a desk and pushing papers around 8 hours a day isn’t for everyone. While challenging, construction is a satisfying career of building a new world and creating value for the community. In the upcoming years, Florida is expected to increase construction in transit and rail transportation, higher education, hospitals, retail and warehouse, offices, apartments, residential, and highway and public buildings, including schools. As an industry, construction and builders can do a better job recruiting talent and enticing young people to pursue a career in construction, or else the cost and time to complete jobs will continue to rise.

But despite the labor shortages, ARC Development is known throughout the industry for our ability to take on projects and finish them as quickly and efficiently as possible without sacrificing worksmanship or going over budget. Our testimonials attest that we’re a leader in the sector.

    What Are Roads Made Of?

    Wondering what are roads made of may have only been a fleeting thought you pondered one day while waiting for the “Walk” signal at a crosswalk, but a thorough answer requires traveling way back through antiquity to look at where roads first came from before we examine the roads of modern day.

    The first roads appeared in the Stone Age to facilitate the need of transporting goods when primitive humans discovered that using pack animals like donkeys and horses were more efficient than using their heads. A travois is a frame developed to be used on roads in Eurasia that is believed to be the first vehicle.  In about 5000 BC, sleds developed, which are more harder to build than travois, but are easier to guide over smooth surfaces, thus necessitating smoother roads. As a result, by about 5000 BC roads, including the Ridgeway, developed along ridges in England to avoid getting stuck while crossing rivers. In central Germany, such ridgeways remained the predominant form of long-distance road till the mid 18th century.

    This leads to perhaps the most important human technological advancement of all time, the wheel, which appears to have been created in ancient Sumer in Mesopotamia around 5000 BC.  It is believed they were used to help reduce the resistance of the ground by being attached under sleds. Some say logs were first used under sleds but as of now there is no archaeological evidence to support this fact.  It has been observed that most early wheels appear to have been attached to fixed axles, which would have required regular lubrication to be effective, perhaps by vegetable oil, leather, or animal fats. Roads needed to evolve from cleared dirt to serve this new dependence on wheeled vehicles.

    The first roads were made of stone and developed in urban areas in Ur in 4000 BC. Advancements in stone cutting made cutting tools more widely available in the Middle East and Greece, where local roads were paved. The best road of the time was constructed by the Minoans that extended 50 km from Knossos in north Crete through the mountains to the port town of Labena that had side drainage and a 200 mm thick pavement made of sandstone blocks bound with clay gypsum mortar that was covered by a layer of basaltic flagstones. This road was a precursor to modern roads with it’s shoulders.


    What are roads made of today? We’ve made some leaps since the times of the Romans. Modern roads went from gravel to cobblestone and granite to asphalt and concrete poured over a compacted base course. Asphalt is sometimes called flexible pavement due to the way it distributes loads and its been widely used since the 1920s. “The viscous nature of the bitumen binder allows asphalt concrete to sustain significant plastic deformation, although fatigue from repeated loading over time is the most common failure mechanism. Most asphalt surfaces are laid on a gravel base, which is generally at least as thick as the asphalt layer, although some ‘full depth’ asphalt surfaces are laid directly on the native subgrade. In areas with very soft or expansive subgrades such as clay or peat, thick gravel bases or stabilization of the subgrade with Portland cement or lime may be required. Polypropylene and polyester geosynthetics have also been used for this purpose[1] and in some northern countries, a layer of polystyrene boards have been used to delay and minimize frost penetration into the subgrade.[2]” Depending on the temperature at which it is applied, asphalt is categorized as hot mix, warm mix, or cold mix. Hot mix asphalt is applied at temperatures over 300 °F (150 °C) with a free floating screed. Warm mix asphalt is applied at temperatures of 200–250 °F (95–120 °C), resulting in reduced energy usage and emissions of volatile organic compounds.[3] Cold mix asphalt is often used on lower-volume rural roads, where hot mix asphalt would cool too much on the long trip from the asphalt plant to the construction site.[4]

    An asphalt concrete surface will generally be constructed for high-volume primary highways having an average annual daily traffic load greater than 1200 vehicles per day.[5] Advantages of asphalt roadways include relatively low noise, relatively low cost compared with other paving methods, and perceived ease of repair. Disadvantages include less durability than other paving methods, less tensile strength than concrete, the tendency to become slick and soft in hot weather and a certain amount of hydrocarbon pollution to soil and groundwater or waterways.

    In the mid-1960s, rubberized asphalt was used for the first time, mixing crumb rubber from used tires with asphalt. While a potential use for tires that would otherwise fill landfills and present a fire hazard, rubberized asphalt has shown greater incidence of wear in freeze-thaw cycles in temperate zones due to non-homogeneous expansion and contraction with non-rubber components. Also, application of rubberized asphalt is more temperature-sensitive, and in many locations can only be applied at certain times of the year.

    When it comes to long term acoustic benefits of rubberized asphalt, the results are inconclusive. Initial application of rubberized asphalt may provide 3–5 decibels (dB) reduction in tire-pavement source noise emissions; however, this translates to only 1–3 decibels (dB) in total traffic noise level reduction (due to the other components of traffic noise). Compared to traditional passive attenuating measures (e.g., noise walls and earth berms), rubberized asphalt provides shorter-lasting and lesser acoustic benefits at typically much greater expense.




    Concrete surfaces are created using a concrete mix of Portland cement, coarse aggregate, sand and water. In virtually all modern mixes there will also be various admixtures added to increase workability, reduce the required amount of water, mitigate harmful chemical reactions and color. In many cases there will also be Portland cement substitutes added, such as fly ash. This can reduce the cost of the concrete and improve its physical properties. The material is applied in a freshly mixed slurry, and worked mechanically to compact the interior and force some of the cement slurry to the surface to produce a smoother, denser surface free from honeycombing. The water allows the mix to combine molecularly in a chemical reaction called hydration.

    Concrete surfaces have been refined into three common types: jointed plain (JPCP), jointed reinforced (JRCP) and continuously reinforced (CRCP). The one item that distinguishes each type is the jointing system used to control crack development.

    • Jointed plain concrete pavements contain enough joints to control the location of all the expected shrinkage cracks. The concrete cracks at the joints and not elsewhere in the slabs. Jointed plain pavements do not contain any steel reinforcement. However, there may be smooth steel bars at transverse joints and deformed steel bars at longitudinal joints. The spacing between transverse joints is typically about 15 feet (4.6 m) for slabs 7 to 12 inches (180 to 300 mm) thick. Today, a majority of US state agencies build jointed plain pavements.
    • Jointed reinforced concrete pavements contain steel mesh reinforcement (sometimes called distributed steel). In jointed reinforced concrete pavements, designers increase the joint spacing purposely, and include reinforcing steel to hold together intermediate cracks in each slab. The spacing between transverse joints is typically 30 feet (9.1 m) or more. In the past, some agencies used a spacing as great as 100 feet (30 m). During construction of the interstate system, most agencies in the Eastern and Midwestern United States laid jointed-reinforced pavement. Today only a handful of agencies employ this design, and its use is generally not recommended by professional contractors as both of the other types offer better performance and are easier to repair.
    • Continuously reinforced concrete pavements do not require any transverse contraction joints. Transverse cracks are expected in the slab, usually at intervals of 3 to 5 ft (0.91 to 1.52 m). These pavements are designed with enough steel, 0.6–0.7% by cross-sectional area, so that cracks are held together tightly. Determining an appropriate spacing between the cracks is part of the design process for this type of pavement.

    Continuously reinforced designs may cost slightly more than jointed reinforced or jointed plain designs due to increased quantities of steel. Often the cost of the steel is offset by the reduced cost of concrete because a continuously reinforced design is nearly always significantly thinner than a jointed design for the same traffic loads. Properly designed, the two methods should demonstrate similar long-term performance and cost-effectiveness. A number of agencies have made policy decisions to use continuously reinforced designs in their heavy urban traffic corridors.

    One of the major advantages of concrete pavements is they are typically stronger and more durable than asphalt roadways. They also can be grooved to provide a durable skid-resistant surface. A notable disadvantage is that they typically can have a higher initial cost, and can be more time-consuming to construct. This cost can typically be offset through the long life cycle of the pavement. Concrete pavement can be maintained over time utilizing a series of methods known as concrete pavement restoration which include diamond grinding, dowel bar retrofits, joint and crack sealing, cross-stitching, etc. Diamond grinding is also useful in reducing noise and restoring skid resistance in older concrete pavement.[7][8]

    A little bit of trivia, the first street in the United States to be paved with concrete was Court Avenue in Bellefontaine, Ohio in 1893. The first mile of concrete pavement in the United States was on Woodward Avenue in Detroit, Michigan in 1909.

      The Number 1 Reason For Road Repair in Florida

      Even though they handle thousand pound vehicles driving on them all day and night, road repair is required from time to time. In Florida, it’s common for roads to experience sinkholes, cave ins, potholes, and depressions. These damages can alter the flow of traffic, sometimes instantly, and create an immediate hazard or danger.

      What can have such a profoundly destructive impact on concrete and asphalt? Water. Water is usually the primary reason necessitating road repair. Water damage underlines the importance of preventative sealing applications.

      Why is water so damaging to concrete and asphalt roads?

      Unless the sealing mentioned above isn’t applied, water will penetrate the asphalt or concrete and seep underneath into the base material, weakening it, and cracking as traffic continues to drive over it, eventually forming a pothole. If the new asphalt isn’t packed properly, water will continue to seep in and future road repair will be necessary.

      “In the last five years, 16 million drivers across the country have suffered pothole damage to their vehicles,” said John Nielsen, AAA’s managing director of Automotive Engineering and Repair. “The problems range from tire punctures and bent wheels, to more expensive suspension damage.”

      Road repair can become costly over time, some studies have the damage cost to U.S. drivers at over $3 billion per year, which is why getting roads built properly the first time around is so important. You know who you can trust with that, ARC Development.
