Best Plants for Xeriscaping

by Ri Industries

Last month we spoke about the benefits of xeriscaping and how to get started in our article ‘Xeriscaping: Benefits and How to Start’. We shared that choosing plants which are native to the region in which you live is the best option for a xeric garden. In this article, we’ll discuss what those plants are. 

To provide you with the best information we can, we went straight to the experts at SA Water. The first thing to consider is soil type and local environment:

  1. Coastal settings tend to have alkaline sandy soils
  2. Plains regions tend to have alkaline loam over clay  
  3. Hills tends to have acidic sandy loam over clay and higher rainfall

Xeriscaping – Benefits and How to Start

by Ri Industries

Regular readers of our articles may remember ‘The Benefits of Xeriscaping’ article we published in August of 2019. After reading the most recent drought report by the Australian Government of Meteorology, we thought now would be a good time to once again discuss xeriscaping. 

According to the May 2022 drought report, rainfall in April of 2022 was below average for western Tasmania, coastal south-eastern South Australia, south-western Victoria, and a large area of Central Australia spanning the south-west of the Northern Territory and interior of Western Australia. Serious rainfall deficiencies (totals in the lowest 10% of historical observations since 1900) are affecting parts of southern Australia for the period starting December 2021. 

Why did this information lead us to write about xeriscaping? Because xeriscaping is landscaping designed specifically for areas that are susceptible to drought, or for properties where water conservation is practiced. Creating outdoor spaces which require little water is not only good for the environment, but it’s also good for your bank account!

There are more benefits than just reducing the amount of water used on lawn, trees, plants, and shrubs. It also reduces pollution since pesticides and fertilisers are not needed and it also removes the need for mowing. One of the best benefits is the ease of maintenance. Less water needed means less time fussing with hoses and sprinklers and the types of plants used typically grow slowly meaning less time spent pruning and trimming. 

How to get started with your xeric garden? 

  1. Determine the best location. Will you remove the entire lawn or just sections? Areas that are least used tend to be the best location for growing these types of plants. 
  2. Group plants by the amount of water they will need. Phgmag.com recommends three zones: 
    1. Zone One (Oasis Zone) – The oasis zone has the most water-dependent plants and requires more maintenance than other zones. 
    2. Zone Two (Transition Zone) – The transition zone requires less watering and maintenance than the oasis zone but has more needs than the xeric zone. 
    3. Zone Three (Xeric Zone) – The xeric zone requires very little water and maintenance.
  3. Replace lawn with mulch, rocks, gravel or a combination.
  4. Choose plants native to the region where you live and learn how drought-resistant each is. 
  5. Determine how to irrigate the garden. A drip irrigation system is often a good choice. 
  6. Make sure you are working with good soil as it will hold water well, provide nutrients, and properly aerate to allow water to reach deep roots. 

Now that you’ve planned your xeric garden, you’re well on your way to helping the environment and saving time, energy, and money.  Stay tuned for our next article which will discuss best choices of plants for South Australia.

What is the Expected Lifespan of a Septic System

by Ri Industries

septic system exposed in ground

What is the expected lifespan of a septic system? We hear this question often. After all, a septic system is not only a big financial investment, but it’s something that causes much disruption when it’s not working properly.

So, what can you expect? For a conventional septic system which is properly designed, well-built, maintained as advised, and not overworked, you can expect it to last for 20 – 30 years. The next logical question is, how do you tick all of those boxes?

The first two are simple. When you purchase a septic tank from Ri-Industries, you are purchasing a properly designed and well-built tank. With over 70 years of experience in the septic tank business in Adelaide, South Australia, Ri-Industries has developed efficient manufacturing techniques to produce concrete septic tanks and septic tank lids of the highest quality that are built to last.

Our article “Common Septic Tank Mistakes to Avoid to Keep Your System Running Well”  addresses proper maintenance you should follow. Fortunately, maintenance is not required often, but it should be done on a regular basis. What does that mean? The answer will be determined based upon the size and the system and amount of use it gets. Typically, pumping every 3 – 5 years is recommended.

Don’t forget about the drain field. Proper care for it will help keep the system working properly. When the drain field is not properly cared for, the wastewater cannot filter correctly, which can cause it to flow into the groundwater, or back through your pipes and into your home. Don’t build structures or park vehicles on the drain field.

Address warning signs of problems promptly. Slow draining sinks/bath, spots of healthy, green grass over the drain field, or bad odours coming from the tank or drain field are common signs of problems. Taking care of the problems early can save you money on the repairs and help extend the life of the system.

How do you avoid overworking the septic system? 

  • Space out laundry loads. Running numerous loads of laundry in a day can flood the field and overfill the tank, forcing untreated wastewater (with solids) into the leach field, clogging the field.
  • Turn off taps when washing up, brushing your teeth, or doing dishes, to avoid running more water than necessary.
  • Don’t put your drain field in a low area that collects water. Excess water seeping into the ground has the same effect as excess water from the house – a saturated drain field that functions poorly and may fail early.
  • Consider low-flow shower heads and water conserving toilets to reduce the amount of water flowing through the system.
  • Be careful what you flush. Our article “Can I Flush This Waste?” has important tips. 

Our website has lots of articles to help you properly care for your septic system. And of course, our experts are available to answer your questions. All you need to do is call 8444 8100.

Laundry Tips to Help Your Septic Tank System

by Ri Industries

Did you know the way you do laundry can affect your septic system? If you read our article last month, you likely do. We discussed common causes of a failing septic system and heavy water usage is one of the most common causes. So, from Ri-Industries to you, here are some laundry tips to help keep your septic system working properly. 

Be careful of washing clothes that are too dirty for the wash. Yes, you read that right. When items with excess dirt on them (like caked-on mud) are added to the wash load, you risk a build up of dirt/mud which can in turn clog the system and damage the absorption of the drainfield.

Spread out your washing. If you don’t accumulate a lot of laundry during the week (2 loads or less), doing it all in one day may be fine. But, if you’re like most of us, the laundry that piles up in your home all week can be too much to put your septic system through in one day. The loads should be spaced apart to give the settlement process time to properly break down the solid matter. If you don’t, the soakage field could fail which can cause extensive damage. 

The septic system uses ‘good’ bacteria to break down the solids which enter it. Excessive amounts of bleach and detergents will damage the good bacteria. By spacing out the load, you limit the amount of bleach and detergent in the system at one time. Also, choose liquid detergent rather than powder. Powdered detergents use fillers or extenders that can clog the soil in the drainfield and permanently damage its absorption ability. Look for a formula with natural ingredients and that is low in surfactants and phosphates.

Did you know many washing machines come with a lint tray, just like dryers do? And, just like dryers, the lint trays need to be emptied and cleaned. Laundry debris and lint can escape into your pipes causing severe blockages. These substantial backups can break down your septic system, so take this tip seriously.

Following these few tips will help avoid costly repairs to the septic system. Do you have questions about these tips or anything regarding the Ri-Industry septic tanks? If so, please call us at 08 8444 8100.

Personal Hygiene Habits and Cleaning Tips to Keep You Healthy

by Ri Industries

Personal hygiene habits can help keep you healthy or, when done poorly, can make you susceptible to illness. With summer holidays and borders opening, now is a great time to review some extra bathroom tips to help keep you healthy. 

The University of South Australia has recently conducted a study on public restrooms. In short, it highlighted the dangers of open toilet lids, uncovered rubbish bins and defective plumbing drains in spreading infections in public washrooms. To best protect yourself when using a public restroom, the authors of the study recommend you minimise your time in the bathroom, wash and dry your hands properly, and don’t use your mobile phone or eat/drink. With these precautions, your risk to infection and illness should be relatively low. 

That covers public toilets, but what about the bathrooms in your home? We’ve previously shared articles with tips to help clean your bathrooms. 

Our article, Helpful Household Cleaning Tips: Bathroom Edition offer these tips:

  • Keep your toilet clean and fresh by scrubbing the inside bowl with toilet cleaner, white vinegar or bi-carb soda.
  • Remove hard water stains with lemon.
  • Remove shower scum with White Magic Eraser or White Vinegar.

For organic cleaning methods, read our article Natural Ways to Keep Your Bathroom Clean. Three simple tips from that article are:

  • Daily Maintenance
  • Use Natural Cleaners
  • Safe Disposal

If you’re looking for information on natural cleaners, we have an article to help you too! Natural Cleaning Products for Your Home will instruct you how to use lemon, vinegar, and baking soda to clean different areas of your home. 

Be sure to click over to each article for more details on each bullet point. 

To wrap-up, wash your hands well, keep the bathroom clean, close the toilet lid when flushing, cover rubbish bins, and make sure the drains are functioning properly to best help reduce the risk of infection when using the toilet.

Septic Tank FAQ’s: Septic Tank Questions

by Ri Industries

Speech bubble with Septic Tank FAQ's written in it.

We have compiled a list of septic tank questions which you may find handy. Please have a read and of course, feel free to call us with any additional questions!

  • Are septic tanks environmentally friendly? Yes, septic tanks are environmentally friendly. In fact, the process they use is all  natural. Commercial treatment plants use harsh chemicals to break down waste, but your residential septic tank uses natural bacteria to break down the household waste. 
  • Should I be concerned about disease? No! While it’s true that improperly treated household waste can contribute to, or cause, illness and disease, a properly functioning septic tank can remove this risk.
  • How long will the septic tank last? Concrete tanks, like those built by Ri-Industries, can last up 40 years if it’s properly maintained.
  • Will my septic tank be damaged by flushing things like pills or bleach down the toilet? The process can be disturbed when chemicals are introduced into the system. The process uses bacteria to break down waste. Chemicals, like antibiotics, and those found in some cleaning products, can cause an imbalance in the ecosystem which can weaken or kill the bacteria. When this happens, solid waste will build up more quickly which can lead to problems in the drainfield. 
  • The power’s out! Will the septic tank still work? The pump requires electricity to pump the effluent into the drain field. Without electricity, the tank will fill up. To help minimise problems, when the power is out try to conserve as much water as possible. Take shorter showers, don’t do laundry, and ration the flushing of the toilets. 
  • Is a plastic septic tank better than a concrete septic tank? There are pros and cons of both but concrete tanks typically last longer, they’re more durable, they don’t need as much maintenance and they’re not usually affected by changes to their environment such as tree roots or changing soil conditions.

The questions above are ones that have not been addressed very often in our blogs. For more questions, answers, tips, and facts please check out some of our previous blogs:

What Happens When a Septic Tank is Pumped?

by Ri Industries

What happens when a septic tank is pumped? What is the process and where do the contents go? If you own a property that has a septic tank, you may be curious.

First, let’s quickly recap how a septic tank works. Simply put, septic tanks allow for the safe disposal of certain household waste products. Wastewater flows down through the sewer pipes in your home and enters the first chamber of the tank, allowing solids to settle (sludge layer). A crust then forms on the surface of the effluent, known as the scum layer. The settled solids are anaerobically digested, reducing the volume of solids. The liquid component flows through the dividing wall into the second chamber, where further settlement takes place, with the excess liquid then draining in a relatively clear condition from the outlet into the soakage field. To learn more, see our articles How a Septic Tank Works and How Do Sewage and Effluent Move Through Septic Systems?

Soil, sludge, excrement and solid waste will build up in the tank over time, eventually requiring the tank to be pumped to make room for more waste to be added. Waste disposal companies begin the pumping process by emptying the tank and removing all the solid waste that has been collected. A tank truck with suction gear, called a gully sucker, collects the waste by sucking the wastewater and sludge from the tank. Once the tank is emptied, the contents will be transported for disposal.

The South Australian government dictates how the contents are to be disposed of. “Septage must either be taken to a facility licensed to receive septage or where this is not reasonable or practicable, applied to land only if for beneficial reuse (for example, in regional locations or small townships).”

We know talking about waste products is not a fun topic, but for those who use septic tanks, this information is important. Knowledge can help keep the septic system running smoothly. For more information on our septic tanks or any of our products, please call 08 8444 8100.

Common Septic Tank Mistakes to Avoid to Keep Your System Running Well

by Ri Industries

Ri-Industries logo and title of article: Common Septic Mistakes to Avoid to Keep Your System Running Well

Septic tank mistakes can be innocently made by homeowners leading to damage and expensive repairs. While you don’t want to think about your septic tank often, a little knowledge and planning can help you keep it in good working order. 

Let’s talk about common septic tank mistakes:

  1. Lack of Maintenance – This is one of the biggest reasons homeowners find themselves with a non-working septic tank. Maintenance is not required often, but should be done on a regular basis. The size and use of the system will factor into how often it should be pumped, but typically it is best to do every few years. 
  2. Toilets Are Not Rubbish Bins –  Rubbish should be properly disposed of, and this does NOT mean flushed down the toilet. Restrict flushing to toilet paper only and the waste that exits in your body. The most common items flushed which should NOT be flushed are feminine hygiene products, baby wipes, toilet paper that is not labeled ‘septic safe’, and nappies.
  3. System Overload – A steady flow of water is best for the septic system. Frequent loads of laundry and exceptionally long showers should be avoided. 
  4. Ignoring Warning Signs – Common signs of trouble include the sink/bath draining slowly, bad odour emanating from the tank or drain field, and spots of healthy/green grass over the drain field. If you see one or more of these, call in a professional. When caught early, repairs may be less costly than if the warning signs are ignored.
  5. Drain Field Care – Waste water gets treated in the septic tank and then it flows into the drain field where it filters through the soil. When the drain field is not properly cared for, the wastewater cannot filter correctly, which can cause it to flow into the groundwater, or back through your pipes and into your home. Don’t build structures or park vehicles on the drain field and avoid overloading the drain field with too much wastewater at once. 

It’s never pleasant to find your septic system not working properly. Avoiding these common mistakes can help you avoid that unpleasantness. If you have questions, please call and speak with one of our experts or you may find the answers in one of our many blogs at https://www.ri-industries.com.au/blog/.

 

HomeBuilder Grant

The Homebuilder Grant and Septic Systems

by Ri Industries

HomeBuilder Grant

If you were planning on building a new home or renovating an existing home any time over the past year or so, you’re likely familiar with the Homebuilder grant. The grant provides eligible owner-occupiers (including first home buyers) $25,000 towards the cost of building or buying a new home or substantially renovating an existing home. The application process is now closed, but the construction commencement requirement has been extended for all contracts signed between 4 June 2020 to 31 March 2021, from six months to 18 months. This is great news as  the construction industry is experiencing a shortage of many materials, such as timber and steel. 

What can the Homebuilder Grant do for you?

  • For those who are building a new home in a non-sewered area, Ri-Industries can provide either a soakage system septic tank or an aerobic waste water treatment system such as the EP10. Funds from the Homebuilder grant can be used for this expense. 
  • The Homebuilder Grant can also be used for home renovations such as adding additional bedrooms and/or bathrooms to accommodate more people. When adding more people living in the home or increasing the use of water in the home and you already have a septic tank, it’s a good idea to see if the current septic system is large enough to handle the increased use. If not, it’s time to upgrade the system to a bigger unit or possibly move away from the old soakage system septic tank to an aerobic septic tank, and take advantage of recycling your waste water at the same time.

It’s been a stressful year to say the least and you deserve some upgrades in your life. If you’ve already applied for the Homebuilder grant and are planning the build of your new home or the renovation of your existing home, be sure to consider your septic system needs. The experts at Ri-Industries will be happy to help you choose the best solution for your home.

Why Rainwater Tanks are Popular and Important in South Australia

by Ri Industries

Rainwater tanks are popular and important in South Australia because they help us conserve water. Let’s look at how they are used and how much water they can save.

In South Australia, rainwater tanks are used in communities without access to reticulated water sources, in communities where good quality water supplies are limited, in areas where local regulations require rainwater storage be provided for bushfire prevention, and in urban areas, such as Adelaide and regional communities, which have access to mains water but owners want to conserve water. 

Some advantages of rainwater tanks include:

  • The use of rainwater costs less than mains water
  • Rainwater causes less erosion to household appliances due to their low salinity content
  • Protects water supplies by conserving mains use
  • Rainwater is softer than mains water which may mean you use less soap, detergent, and shampoo

To read more about the benefits of rainwater tanks, please see our blog, What are the Benefits of Rainwater Harvesting.

One of the main benefits of rainwater harvesting is the ability to conserve to water. So, how much can you save? Put into everyday terms, a family of four in Adelaide, with a 100m² roof catchment area and a 1000L tank can capture enough rainwater in one year to:

  • Flush a toilet twice per day per person

OR

  • Provide one bath per person per week (150L tub)

OR

  • Run a sprinkler system for one hour five days a week (1.5 L/min)

OR

  • Wash dishes in the dishwasher every day

OR

  • Give each person a 5 minute shower twice a week (standard flow shower)

If we’ve piqued your interest in rainwater harvesting and you would like to learn about our rainwater tanks, please see information on our website or call us at 8444 8100.

Rainwater Harvesting Benefits Farming and Agriculture

by Ri Industries

Farming and agriculture play an important role in Australia. Rainwater tanks contribute to their success by reducing their reliance on mother nature.

Farms require an abundance of water to keep their crops and livestock healthy. In Australia, which is known for its dry climate, rainwater tanks Adelaide can help keep the water flowing despite a lack of rain. Another concern of farmers is the outbreak of disease or parasites. When this occurs, it’s in their best interest to have access to their own clean water supply.

Farmers use rainwater harvesting, which is the primary and most efficient component of water supply management for rural and regional Australia, to fill the rainwater tanks. Rainwater that falls on the roofs of houses, sheds, and other farm buildings is collected and stored in tanks. This is an easy way to locally collect water and use it where and when it’s needed.

The collected water can be used in various applications such as feeding stock, spraying crops, and storing water for firefighting. The quality of rainwater is typically superior to water from sources such as dams and local waterways which means it can also be used for domestic use.

Rainwater harvesting is expected to become more popular in the years to come. This is in part due to the cost-effectiveness of rainwater harvesting as compared to setting up main water and sewage services in semi-rural and rural areas. In fact, rainwater harvesting is so cost-efficient that arguments have been made that it should be used more widely in urban areas as well.

The bottom line is that safely storing water in tanks is a cost-effective way to see you through many types of water crises, including drought. If you’d like to learn more about rainwater harvesting and/or Ri-Industries rainwater tanks, we have a range of articles you can read available on our website. Of course, we’ll be happy to take your call to answer questions as well. You can reach us at 08 8444 8100.
