Three Types of Wastewater

Three Types of Wastewater

Three Types of Wastewater

Oh no! You’ve experienced a flooding or sewage emergency. What happens next?

The steps you’ll take to begin addressing water damage in your home depend heavily on the type of wastewater you’re dealing with.

BLACKWATER

Blackwater refers to wastewater contaminated with human waste. Blackwater comes from flush toilets, urinals and bidets, and contains human waste such as urine and feces as well as toilet paper. Blackwater can also include water from food preparation sinks, dishwashers and other sources. Raw sewage is classified as blackwater. Blackwater is a haven for dangerous bacteria and pathogens that must fully decompose before being released into the environment. It can also be contaminated with dissolved chemicals and particulates, making contact even more dangerous.

When it comes to flooding emergencies, blackwater floods are the most dangerous and the most destructive. Because of the extremely unsanitary conditions of the water, porous and absorbent items such as carpets, upholstery and drywall are often unsalvageable. Contact with blackwater via ingestion or skin contact can cause illness.

If you suspect that the flooding situation involves sewage or blackwater, it is advisable to contact a professional plumber and a water restoration expert to assess the situation before attempting to begin remedying it yourself.

GREYWATER

Greywater, or sullage, refers to wastewater that is not contaminated with fecal matter. Greywater could include water from bathtubs and showers, washing machines, dishwashers, and sinks. It generally contains fewer pathogens than blackwater and can be reused for non-potable purposes, such as toilet flushing. Greywater still contains small amounts of contaminants and can induce illness if ingested.

Floods by greywater can be caused by a weather event, an overflowing plumbing fixture or appliance or even a broken pipe. This type of greywater can saturate carpeting, furniture and drywall. If you experience a home flood with greywater, take caution when beginning the cleaning process. Wear protective gear, and keep children, pets and individuals with a compromised immune system away from the flooded area. If the flood is extensive, such as several inches of water in the basement, it is advisable to hire professionals to safely clean up and decontaminate the area. Cleanup must begin immediately–greywater can become blackwater in as little as 48 hours.

CLEAR WATER

Floodwater that does not post an immediate health threat is known as clean water. Seems obvious, right? Clear water floods can result from malfunctioning appliances, toilet holding tanks, and melting snow, rainwater and groundwater. Clear water home floods are generally safe for you to clean up yourself but remember–time is an important factor. Standing clear water can become greywater in as little as 48 hours.

Backflow Prevention – What is it and Why Do We Need it?

Backflow Prevention – What is it and Why Do We Need it?

Backflow Prevention –
What is it and Why Do We Need it?

Cross-connections in plumbing are defined as actual or potential connections between a potable and non-potable water supply. This can constitute a serious public health hazard. There are numerous well documented cases where cross-connections have been responsible for contamination of drinking water and have resulted in poisoning and or the spread of disease through the water.

This problem is a dynamic one because piping systems are continually being installed, repaired, replaced, or extended. Control of cross-connection is possible, but only through knowledge and vigilance. Under Public Law 99-339, the “Safe Drinking Water Act” (SDWA) was passed in 1986. This act placed the water purveyor with the primary responsibility for preventing water from unapproved sources, or any other substances, from entering the public water system.

All Municipalities with public water systems are required to have a cross-connection control program in place to protect the water supply. Backflow prevention devices are installed on water supply systems for this reason.

TYPES OF BACKFLOW DEVICES

There are many types of backflow devices, but there are only three types that can be tested:

1. Pressure Vacuum Breakers – PVB

These vacuum breakers are used where a condition of back-siphonage could occur. Back-siphonage can be the result of a total loss of pressure within the system due to a breakage in the main supply piping or other reasons. The pressure vacuum breaker is a mechanical device consisting of one spring loaded air inlet valve on the discharge side of the device. This device includes shut off valves and test ports on each end of the device. They are used in low or high hazard conditions.

2. Double Check Valve Assemblies – DCVA

The double check valve assembly is a mechanical device that consists of two spring loaded check valves. This device includes shut off valves and test ports on each end of the device. This device is effective against back pressure and is used to isolate low hazard pollutants (non-health threatening/non-toxic).

3. Reduced Pressure Zone Assemblies – RPZ

The reduced pressure zone assembly is a mechanical device that consists of two spring loaded check valves and a relief valve. This device includes shut off valves and test ports on each end of the device and can be used for backpressure, back-siphonage, and it can be used in toxic or high hazard conditions.

WHAT IS REQUIRED

A backflow prevention device needs to be inspected annually. The 2018 Uniform Plumbing Code in section 603.2 states:

Devices or assemblies installed in a potable water supply system for protection against backflow shall be maintained in good working condition by the person or persons having control of such devices or assemblies. Such devices or assemblies shall be tested at the time of installation, repair, or relocation and not less than on an annual schedule thereafter, or more often where required by the Authority Having Jurisdiction (AHJ). Where found to be defective or inoperative, the device or assembly shall be repaired or replaced. No device or assembly shall be removed from use or relocated without the approval of the AHJ. Testing shall be performed by a certified backflow assembly tester in accordance with ASSE Series 5000 or otherwise approved by the AHJ.

WHAT THE RESPONSIBLE PARTY SHOULD KNOW AND DO

1) Backflow devices are not limited to being installed on the main water line into the building from the water purveyor. You may also have them throughout the building on supply lines to equipment or machinery within the building. These are installed to protect the occupants within the building from a potentially hazardous condition. They should also be set up on an annual inspection plan.

2) If you are responsible for the safe operation of any backflow device you should partner with an experienced, licensed, certified, and insured backflow tester. Qualified testers are individuals who have passed an approved certification course and hold a valid license to test and repair or replace the devices. They may work alone as a sole proprietor or be employed by a larger company. Regardless, find someone who is knowledgeable on the various devices and knows what the local codes require in your area. They should be knowledgeable on how the device operates, how it should be properly installed, what the testing parameters are, and how to file all necessary documentation and/or permits that may be required for the work.

3) The testing procedure usually takes about 30 minutes. During this time the water will need to be shut down on the water line where the device is installed. Oftentimes this could be the entire building.

4) Backflow devices are well designed. Most all devices can be repaired. Replacement is not always necessary.

7 Things to Consider when Contracting a Commercial Plumber for your Business

7 Things to Consider when Contracting a Commercial Plumber for your Business

7 Things to Consider when Contracting a Commercial Plumber for your Business.

The plumbing system in a commercial building is much more complex than a residential plumbing system and often a forgotten part of the business. The plumbing system is taken for granted until something starts leaking or stops running. Any business, large or small, must remain open and run efficiently in order to be successful and profitable. A sudden failure in the plumbing system could stop any business in its’ tracks.

The following are some things to consider when it comes to hiring a commercial plumber to work in your building. You don’t want to make costly mistakes when it comes to your commercial plumbing. You want to make sure the plumber you are hiring is licensed and insured, as well as knowledgeable and experienced in the commercial aspects of plumbing. Hiring a licensed plumber with commercial plumbing experience isn’t as simple as it should be, and there are several things that you don’t want to go wrong during the process. In order to ensure that your commercial plumbing needs are met and the best possible services rendered, you’ll have to shop around before making your decision.

Here are 7 things you need to consider before securing the services of a commercial plumber:

1. Is the plumber licensed, experienced and insured?

Licensed plumbers will be more likely to have the knowledge necessary to ensure any work you have done follows all plumbing and building codes; liability insurance will protect both parties in the unlikely event of a costly mistake. Both are critical when it comes to hiring a commercial plumbing contractor. Remember, a commercial plumber should be experienced with plumbing repairs and maintenance for businesses of all types. Think of the many types of businesses that rely on plumbers. Everything from a gas station to a restaurant to a manufacturing plant needs working plumbing so the commercial plumber you hire should have experience fixing the plumbing in your specific type of business.

2. Does the plumbing company charge for estimates?

Before the plumber comes out to your business, make sure you know whether you’ll be charged for the inspection. It depends on the plumbing company whether or not this fee will be assessed. Sometimes these fees are called “trip charges”. That’s just the cost for the plumber to stop by and assess your problem before any real work begins.

3. Are rates hourly or does the plumber charge a flat rate fee?

In order to avoid unnecessary overages, check to make sure the number the plumber quotes you is either all-inclusive of the labor and parts necessary or if you will be charged by the hour. You don’t want to get nickel-and-dimed by the company for unknown charges. It pays to know exactly what they’re charging you for and how they’re levying those charges.

4. How long has the plumbing company been in business?

Commercial plumbers that have been around for a while will be more likely to have favorable reviews from the community. In addition, an older, better established company is more likely to have experienced plumbers with proven track records for good quality work. Established companies are also more likely to provide 24-hour emergency service. Remember, your business may be at a standstill until the plumber can fix the problem.

5. Can the plumber provide references of other customers?

It is always good to try to obtain references from the plumber from customers they have previously done work for. These references can be contacted and can provide valuable information about the plumber. This will build confidence in your decision on who you hire for your plumbing work.

6. Does the plumbing company sub-contract their work?

Some companies will sub-contract their work to other plumbers or independent contractors. This is not always the case, but it is something that should be asked when hiring a plumbing company. You want to be sure the plumber doing your work is a qualified employee of the company you are hiring.

7. What is the warranty policy?

It’s important for plumbers to guarantee their labor when they are rendering services to your business. Be sure to learn what the protocol is for claiming a warranty before you sign on the dotted line. Most often the plumbing fixtures are covered by the manufacturer’s warranty, but you should be concerned about how long the plumber will guarantee his personal work (labor).

If your commercial plumber has checked off all 7 things to consider when hiring a commericial plumber, you are in good shape to finish the project!

Top 3 Ways to Keep a Green Lawn

Top 3 Ways to Keep a Green Lawn

Top 3 Ways to Keep a Green Lawn

It’s May and everyone is looking for that eye-catching green lawn. Temperatures are moderate, rainfall is abundant, and you could probably cut the lawn twice a week if you really wanted to. This week we are looking at spring turf applications; how they work, and what you should be doing to promote strong stands of green grass and minimal weeds. While there is a world of science behind turf programs, we are breaking it down to the basics that will drive the best results.

Here are the best tips to keep your lawn green all season long:

1. Timing is Everything:

Good weed control starts before the grass is growing. The timing of applying weed control products can be just as important as the application itself. For both cool and warm season grasses the first application almost always involves a pre-emergent weed control. Pre-emergent works by inhibiting the germination of seeds that are dormant in the soil, therefore, timing the application for when soil temperatures are right for seed germination is critical.

2. There's Bad Before the Good:

While pre-emergent weed controls help to limit certain types of weeds; mostly crabgrass, it’s not impactful on broadleaf weeds. “Broadleaf weeds” are what we recognize as Dandelions, Clover, Buttercup and other commons weeds. The best way to treat these types of weeds is to apply a post-emergent herbicide. Post-emergent herbicides work to kill weeds after they have germinated. When trying to achieve a beautiful lawn, you’ll have to wait until the bad weeds come out, so you can feed the lawn to look good!

3. Feed Me:

After a long winter that’s exactly what your lawn is thinking; FEED ME. As grass transitions from a dormant to an active state, lawns need nutrients to stimulate new growth. Early Spring fertilizers that are higher in Nitrogen will fuel vegetative growth, providing those lush green lawns we admire.

While developing and maintaining a strong lawn doesn’t happen overnight, or in any one season, there is never a bad time to start. By treating the lawn with the proper fertilizers in the spring you minimize the competition from weeds. This will give your turf the headstart it needs to excel through the landscape season!

Start Irrigation Out Right

Start Irrigation Out Right

Start Irrigation Out Right

If April showers bring May flowers, what follows May flowers? If you’re in elementary school, the answer is Pilgrims. For the rest of us, the answer is a little less witty. As the cooler, rainy days of early Spring fade away, we are faced with the longer, hotter and more drought prone days of summer. While this may mean a day at the pool for some of us, it’s the most stressful time of the year for your sites’ landscaping. To overcome these hot dry days and to help lawns and plants stay healthy, and to maintain your brand image, underground irrigation systems offer a strong solution.

If Spring has sprung where you are, it’s time to get ahead of the what’s next and get those irrigation systems started! Here are some things to consider when activating irrigation after a long winter:

1. Timing:

While below freezing temperatures will wreak havoc on irrigation systems that are active, the reality is that they can be activated far in advance of when they are needed. Starting your system early in the Spring allows you to choose when to run the system and ensures that the system is ready when you’ll need it.

2. Be Prepared:

What could possibly go wrong with an irrigation system that has been winterized and hasn’t operated since fall? Unfortunately, a lot! To have the most efficient process in place when starting irrigation systems, it’s best to have an established NTE value set with your contractor. This allows for smaller, less costly repairs to be made on the spot; saving time and money in the long run.

3. What Should Be Done:

Here’s what you should expect as part of the activation process: the entire system should be run, adjustments to the heads completed and times on the controller set based on the current needs. When larger issues are found, cost estimates on repairs should be provided immediately. When your contractor leaves the site, the irrigation system should either be completely operational or you should have a full report outlining any issues; with cost estimates included, so you can make the necessary repairs.

4. Next Steps:

Once your systems are started, it’s not over. To ensure proper operation and efficient use of water as a resource, an ongoing monitoring program should be in place. Monthly wet tests to check for needed repairs and adjustments to system run times will help to maximize the systems’ effectiveness and deliver a responsible use of water.

As the seasons unfold the need for irrigation will follow. The first step is to activate the irrigation system, and the points outlined above will help to get things off to a good start.

Putting the Snow Season to Bed

Putting the Snow Season to Bed

Putting the Snow Season to Bed

How to Say "Good-bye Snow!"

The calendar told us that winter was over back on March 21st but Mother Nature hadn’t given in until April was well underway. At this point, only the northern most areas should have any concerns with accumulating snow and the better part of the nation is well into landscape clean ups and mulching.

All that’s left to calling it a wrap are the end of season close outs. While much of the effort towards snow and ice management is focused on the startup and execution of the services, closing out the year is just as essential to continued success and developing improved processes for the next winter.

Critical and useful topics to review at the end of the snow season:

Site Reviews

It’s just a reality of delivering snow removal that parking bumpers get dislodged, curbs get broken, and plants compromised. Yep, things tend to get damaged on site. Conducting a site walk to review site conditions, identify any damages and to build a repair strategy is always a good idea.

Equipment

 As much as you wanted to see snow stakes installed and equipment dropped on site back in November, you want them gone now. Typically, having these items offsite by the end of April should be a reasonable expectation.

Site Clean Up

Funny thing about plowing snow, you not only pile the snow, but you capture all the trash and debris that was on the ground before the snow fell. So, when snow piles melt all the debris that was collected is left behind. For sites with environmental concerns where sand is often an alternative to salt or other deicers, a brush sweep of parking lots is often needed to remove excess sand.

Lessons Learned

Every season brings its own challenges and learning experiences. To better be prepared for the next winter, schedule a post season meeting to review scopes of work, level set expectations and discuss the wins and opportunities in service delivery so that you can build on the lessons learned to have an even better season next year.

While we are enjoying the longer days and warmer weather, don’t lose sight of ending the winter strong and using it to start preparing for next year.
