Why collect rain water?

Water is a very precious resource.

Increasing water restrictions mean there are limits on using mains drinking water to wash cars, fill pools and water your garden. Preparing for water shortages by installing a modest rainwater tank means you will be able to continue your lifestyle regardless of the weather or current government policy.

Many rural centres like Armidale, Goulburn and Orange are almost perpetually on level 5 water restrictions with day zero (no water) being an imminent threat. Having your own water supply is responsible, practical and great lifestyle insurance.

You should be able to wash your car, fill your pool and water your garden whenever you want.

The best part about using rainwater is that after the initial investment, rainwater harvesting is practically free.

What size water tank do you need?

The size of a tank is based on your budget, space available and your usage, as a rough guide:

  • Car washing or watering a small garden: 2,000 L – 3,000 L
  • Toilet flushing, clothes washing and small gardens: 3,000 L – 5,000 L
  • Topping up pools, toilet flushing, clothes washing and larger gardens: 5,000 L – 20,000 L

It is best to get a technician out to size your tank based on your intended usage.

Rainwater helps plants grow

Avid gardeners know that their plants spring to life after a good rain shower. There are many theories why this is the case, but a lack of chlorine and different PH is probably the most likely reason.

Chlorine is used in Sydney’s drinking water to kill organic life, viruses and bacteria. It is a naturally occurring micro-nutrient, but at higher levels will retard plant growth and health. To cope with chlorine toxicity, many plants accumulate excess chlorine it in their leaves which causes bleaches, curling and other disfigurements.

Depending on weather conditions Sydney’s rainwater has a PH of about 5.5, it dissolved CO2, which makes it slightly acidic. This helps dissolve nutrients in the soil and makes it available to your plants. Sydney’s drinking water is closer to neutral with a PH of around 7 and is carefully managed for total dissolved solids.

Bushfire plan

Strong winds during a bushfire carry embers hundreds of meters ahead of a fire front. This means that even if you are several streets away from any bush area your home is still at risk.

When rural and structural firefighters use hydrants and drinking water to fight fires, the water pressure drops. You don’t want to be the home at the end of the line that burns due to not having any water.

Having a static water supply on your property like a water tank means that firefighters have access to water when needed to protect your home. Consider getting a larger tank in the range of 10,000L – 20,000L with additional fire fittings.

NSW Fire + Rescue and Rural Fire Service use 2-inch fittings and forged Storz 65 fittings for their hose connections.  Having these fittings available on your tank make it easy to tap in.

If you are in a bushfire prone area, discuss with your technician about getting an appropriate fire-resistant steel or concrete water tank.

Customer Reviews

The team at Omega were great, from the moment I called them they were able to help straight away and start the job the next day. Reece and Adam who did the job were very friendly always early and completed what they needed to do for the day always on time and have done a great job it all looks superb. They both worked extremely hard even on the hot days. Definitely recommend using Omega again for any plumbing and drainage needs.read more

First Adam arrived promptly and strongly encouraged me to watch him jet the sewer line so I could understand any problems as to why sewerage overflowed outside and my house flooded with bath water. Understandably I was extremely anxious and upset with houseful of guests and toilets not working properly and the prospect of major work to pipes. Reassured by projects manager who had Stephen and Nick arrived within couple of hours. They were joined by Todd who all had the main area of concrete cut up quickly and left tidy for main pipe replacement the next day. Very courteous and the men mopped my garage floor clean before they left. Yes I recommend this crew.read more

Jordan C & Adam did the installation of our new hot water system. Was a bit tricky but they didn’t leave until the job was complete even though what was going in was a bigger size than what they were replacing, they needed carpentry skills too. Both men were very professional, friendly, hard working & turned up on time. Thank you Jordan & Adam!read more

They were pretty quick. Sent the assessor within two hours. Matt gave me quite few options to choose from. They are expensive. But the work was very good. Steve and Roma, two young guys, came sharp on the scheduled time and did a flawless job. They were dey friendly and courteous. Even if I spent a bomb, at the end I was happy. Thank you.read more

I had several ceiling lights in my apartment replaced by Selim from Omega Services. He did a good job, and was very polite and helpful. Other people I dealt with from the company seemed efficient and helpful too, and they were able to come out to do the job within a couple of days at a time that suited me.read more

From the moment I called Omega Home Services, Ryan was the first to come out, our water heater was leaking. Of course it has to be replaced. Being the long weekend, Ryan left his number in case water heater broke down further, and Ryan said Omega would put in a temporary water heater, well the heater broke down that same afternoon a temporary heater was installed.The service was prompt and efficient. By Tuesday new water heater installed. They left the place clean , took away the old water heater. I highly recommend Omega Home Services.read more

I tried Omega to fix a long standing intermittent issue with my air conditioning that another service company had on two consecutive years failed to identify, said there was nothing wrong and charged me a callout fee.Although Omega didn't fix it completely on the first attempt, they came back without question, and at no charge, and found the issue on the second attempt. Their customer service is friendly and the follow-up calls are great. I won't be using anyone else in the future.read more

We used Omega to inspect our drain due to blockage in the toilet. After the inspection, it was determined that our whole sewer line needed replacing. They started working next day. The guys from Omega (especially Romer, Steve and Josh) were always professional, polite, early to arrive and good at communicating what was happening during the process. We would recommend their services to anyone needing work done on their home.read more

Selim came to my home changed all the lights in my new home to perfection. I was concerned from previous experiences that it would not have been done to my satisfaction. Selim was amazing. I’m in construction and can say his work is flawless. He also checked other electrical concerns I had with the switch board. He fixed that also for me making me feel at ease.Will definitely use Omega again with Selim. Thank you.read more

Nelson from Omega Services came and installed a brand new hot water system for us last week. The water heater delivered the first time was found to be faulty. Nelson and his colleague immediately got in touch with the company and quickly arranged for its replacement. The new one was delivered right next day. In the meantime, to make sure that we did not have to suffer a 24-hour waiting period without hot water running in the house during winter time, Nelson and his colleague installed us a temporary hot-water system. Then, Nelson returned the next day and installed the new system for us straight away, and also gave us some good tips on how to use and maintain the new system. Overall, we are very happy about the services provided by Nelson and by Omega Services. Highly recommended!read more
