Alice Springs garden watering planner a first for arid Australia

Alice Water Smart has today launched a new web-based tool that works out the ideal garden watering schedule for Alice Springs’ gardens and the local environment.

It is the first tool of its kind for arid Australia, and was developed in partnership with the national savewater!^® Alliance. Its launch also coincides with the launch of Alice Water Smart’s new website.

 In just a couple of minutes, anyone who owns a garden in Alice Springs, whether they be home or business owners, can find out how much water to use and when. It also compares the recommended schedule with current use, so gardeners can see how much water they can save.

 Alice Water Smart Project Manager Les Seddon says that more than half of all water wasted in Alice Springs is through overwatering plants.

 We have completed more than 1000 Water Efficiency Consultations and found that overwatering is the biggest culprit in water waste.”

 “The Garden Watering Planner will help Alice Springs garden owners save water, money and time. It is incredibly easy to use and each homeowner can print out a personalised watering schedule for their garden.”

 “For a long time, Alice residents have found it difficult to work out how much water their garden actually needs and very few were getting it right.”

 There are so many variables, such as plant age, size and root depth, as well as the types of irrigation being used and our unique climate. No wonder it is confusing!”

 “The Planner takes into account our varying climate, such as the mid-February heat when plants are under the most stress, and the mid-winter frosts when water in irrigation pipes is at risk of freezing.”

 It also works out the best watering schedule for different types of plants, such as natives and drought tolerant plants, grape vines, citrus, palm trees, vegetables and lawn areas.

 For example, if you want to know the recommended frequency and duration to water native shrubs that are between 3-12 months old, the Garden Watering Planner will do that for you.

 The personalised report details the ideal watering schedule for each season and offers advice on the best types of irrigation to use for those plants.

 The average water saved from making a simple irrigation change, such as scheduling or the type of sprinkler pop-up used, is around 224 kilolitres, or $390 per year.

 Garden design, local Alice Springs plants, and the importance of root depth are also features of the Water Planner.

 “Many residents water their gardens every day. This is encouraging shallow roots, which are prone to heat stress, dry out quickly and can only access a small amount of water.”

“We recommend watering longer and less often to encourage deep-rooted plants.  The roots live in cooler soil and can access more water so they help the plant better cope with hot, dry periods.”

Alice Springs’ new recycled water scheme ready for testing

New water recycling facilities have been commissioned in Alice Springs this week and will undergo three months of testing before the water is supplied to businesses and institutions south of Heavitree Gap.

 As part of the Alice Water Smart Reuse Project, the new treatment processes at the Alice Springs wastewater plant will improve the quality of recycled water available.

 Around ten large businesses and institutions south of The Gap will use the water for irrigation and horticultural purposes, such as watering gardens at caravan parks and the cemetery, as well as road and civil construction works.

 “It will save around 220 million litres of the drinking water that is currently used for these purposes each year. That’s equivalent to 100 Olympic sized swimming pools”, says Alice Water Smart Project Manager Les Seddon.

The new facilities include an architecturally designed building to house gravity filters and UV reactors, as well as 3.5km of new network distribution pipe and an additional 2.5 Megalitre storage tank.

 As part of the three-month testing period, Power and Water Corporation and the Department of Health will carry out a series of validation checks to ensure the system is robust.

 "Along with water quality testing, we’ll be monitoring how the system works under various operational conditions, such as when there is peak demand or low water levels in the tanks.”

 “We are currently in discussions with businesses and institutions south of the Gap about how they can access the scheme and we look forward to that first turn of the tap.”

 95 tonnes of special sand media has been brought in from NSW for use in the system’s new gravity filters; which has some irony for a place that is surrounded by sand.”

 "The certified sand has a high quartz content, so it is quite strong and won’t break down into powder form to clog the system. The sand grains are uniform in size to allow wastewater to filter through, and small enough to pick up tiny solid particles along the way.”

 After the sewerage has travelled through several wastewater ponds over a 70-day period, the recycling process takes about one hour, which includes the following five steps:

 Acid and coagulant is added to a reactor tank to modfy pH and bind fine solids together

Waste water enters a Dissolved Air Flotation (DAF) tank to inject air and allow solid particles to float to the top (which are scraped off and sent to waste)

Partially treated water enters the new gravity media (sand) filters to remove more solid particles and further improve quality

Pumps push the water through 80 high intensity UV lamps to disinfect pathogens (disease forming bacteria)

Recycled water is then injected with chlorine and stored in two 2.5 megalitre storage tanks, from where it is accessed by the end user.

 Testing is expected to be complete by mid December and will be available for customers straight away.

ALICE SPRINGS' FIRST LEAK DETECTIVE UNCOVERS THOUSANDS OF DOLLARS GOING DOWN THE DRAIN

New ‘leak detective’ skills and equipment have arrived in Alice Springs to help businesses and homes save water.


The leak detection initiative is the result of a partnership between Alice Water Smart and a local plumber.

The local ‘detective’ and plumber, Jordi Chalmers has already detected ‘mysterious’ leaks in several businesses, saving thousands of dollars going down the drain.

“Just recently I found a leak that was losing $13,700 worth of water (7.9 million litres) per year” said Jordi Chalmers.
“Water bills and a water audit can identify that there is a leak, but they are often difficult to find, particularly if they are underground.”

Of the 50 businesses and organisations that Alice Water Smart has worked with, 42 have been found to have a leak.

When Alice Water Smart was looking to the plumbing industry for help to detect some of the more difficult, unexplained leaks in buildings and gardens, Mr Chalmers visited Queensland to complete specialist training and invest in a state of the art acoustic leak detective device.

“It’s part technology, part experience and it works a bit like a bat’s sonar!”

“We use the acoustic listening device to sound out the leaks. Leaking pipes have a different ‘pitch’ to pipes that aren’t leaking.”
Large organisations are on average leaking up to 16.5 kilolitres (kL) per day, equating to just over $10,000 worth of water per year off their bottom line.

Small businesses are on average losing 25% of their water use to leaks, at a cost of $3,362 a year.

“The total volume of water lost by businesses audited by Alice Water Smart is on average 5,300 litres a day - that’s more than one average backyard swimming pool (30,000L) per week”, says Alice Water Smart Homes and Business project manager Liz Locksley.

“That’s around 22% of water that is metered and paid but leaking away unused on their premises.”
