MUCH of Sydney’s water and sewage system is more than 100 years old; the system was built for a Sydney population of 3 MILLION People! Not 5.5 … 9 or 10 Million People …
HOW CAN SYDNEY WATER ADDRESS OVERDEVELOPMENT?
The Tsunami of sewage is not confined to Castle Hill … it is a problem across Sydney … sewer waste pours into the Sydney Harbour water catchment, and into the Harbour; it has made its way into the storm water system and onto Coogee Beach through Coogee’s sewage system …
–the situation was worse after heavy rainfall with sewers overflowing into the storm water system
-posing real risks to public health
WaterNSW has also revealed that housing developments built too close to pipelines and canals in Western Sydney have:
-resulted in impacts to the water quality (contamination)
-increasing urbanisation in western and southwestern Sydney resulted in increased pressure on the integrity of critical water supply infrastructure; namely the Warragamba Pipeline and the Upper Canal
It is investigating “water augmentation strategies” to service the booming population …
that means a Water Treatment Plant, with a raw water pump station and treated water pump station …
MARCH 2019 in ‘The Shire’ …
“You cannot imagine what kinds of things are floating down our driveway and under our house – condoms, baby wipes, poo, all in a huge stream of sewerage water.
“We put this down to theoverdevelopment in the shire and the fact that infrastructure has not been updated to cope with the extra sewer.“

‘It’s all well and good to drink recycled water until someone forgets to add enough chlorine or whatever. Or someday something doesn’t actually get killed by it or is too small to be filtered out. Then there is the effect of tiny quantities of excreted drugs that form cocktails that you take in over years.’
COMMONSENSE would dictate … wouldn’t it … that rather than precipitate even more major health issues like that of a number of Flu viral illnesses, MERS, SARS and now CoronaVirus that we anticipate and act accordingly … stop with the HT Housing Ponzi, the high immigration and visa manipulation population explosion …

The ratings agency Moody’s is warning that NSW faces significant pressures on its budget as it grapples with climate change and increasingly severe droughts and bushfires.
*Moody’s also warns that “water-related stress” will be the most significant issue for Sydney by 2030, with “large scale infrastructure investment” needed to ensure the city has enough water…
“In addition to hindering agricultural production, the prolonged drought is also exacerbating future water stress risk in Greater Sydney – an area that accounts for a growing share of NSW’s overall economy.
“We currently consider water stress to pose the greatest risk to this part of NSW over the longer term.”
*It is important to note that the key reason why Sydney’s water supply is falling faster than the Millennium Drought is because the city’s population has ballooned by one million people (20%) since that drought ended in 2006.
Obviously, with Sydney’s population officially projected to increase by 1,700 people every week over the next half century, all due to mass immigration. And with Sydney’s population projected to almost double to 9.7 million by 2066:
Water shortages will become an increasing problem for Sydney, even before accounting for reduced rainfall and increased evapotranspirationrates from climate change.
This immigration-driven population explosion will necessarily require a battery of energy-hungry desalination plants to be built along Sydney’s coast. And given desalinated water is around four times as expensive as traditional dam water:
These desalination plants will necessarily mean that household water bills will rise dramatically, which will adversely impact lower income households in particular.
Don’t just take my word for it. Modelling by Infrastructure Australia in 2017 projected that household water bills would more than quadruple in real terms because of population growth and climate change,rising from $1,226 in 2017 to $6,000 in 2067. The report also warned that“the impact of these changes on household affordability could be substantial… and could lead to significant hardship”:
Here is another textbook example of how the mass immigration ‘Big Australia’ policy is wrecking living standards for the working class, as well as threatening Australia’s water security.

CURRENTLY in Sydney despite Level 2 water restrictions our population is increasing, and recent per capita water usage rates have actually increased …
Infrastructure Australia in 2017 projected that household water bills would more than quadruple in real terms because of population growth and climate change, rising from $1,226 in 2017 to $6,000 in 2067. *
AGAIN with vested interests at the Top End … and Beryl’s guvmnt pushing for de$al plant$ … over and above recycling …
IT isn’t half obvious, is it, what the solution is?
Emma Johnston, Dean of Science at UNSW Sydney, is the latest to warn that Sydney’s water supply is under threat from a combination of population growth, reduced rainfall, greater evaporation, and contamination from bushfires. Therefore, more desalination plants will need to be built:
With water restrictions increasing around NSW and talk about Sydney moving to level three sanctions, people are starting to ask what happens if the city’s water supply becomes critically low?
The prognosis is not good.
*Long-term climate forecasts show the drought continuing for a long time. In addition, our population is increasing and recent per capita water usage rates have actually increased.*
Now there is a new threat: the increased risk, severity and extent of bushfires in Australia as a result of climate change…
An enormous amount of ash and debris has built up in water catchment areas as a result of the fires. Our declining supply of fresh water has inevitably suffered some form of contamination, and this will only get worse when the first decent rains fall.
Compounding matters, the bushfires have destroyed much of the river-side vegetation, which acts as a barrier to erosion, meaning run-off and sedimentation will increase.
This combination of factors has very serious potential consequences for our drinking water…
Big cities, regional centres and small hamlets are all going to need more sources of potable water…
Desalination is expected to become an increasingly critical water source for many coastal populations.
Australia has an enormous coastline and we can afford to do desalination well.
Let’s get real. The main driver of Sydney’s budding water shortage is mass immigration.
Sydney’s population has grown by around 1.3 million people (36%) since the Sydney Olympics, and it is projected to grow by another 4.5 million people over the next 48 years – all due to mass immigration:
This population explosion will necessarily require a battery of desalination plants to be built along Sydney’s coast. And given desalinated water is around four times as expensive as traditional dam water:
This necessarily means household water bills will rise dramatically, which will adversely impact lower income households in particular.
Indeed, modelling (Deleted?) by Infrastructure Australia in 2017 projected that household water bills would more than quadruple in real terms because of population growth and climate change, rising from $1,226 in 2017 to $6,000 in 2067. *
The report also warned that “the impact of these changes on household affordability could be substantial… and could lead to significant hardship”:
Here is another example of how the mass immigration ‘Big Australia’ policy is wrecking the living standards of the working class.
Australia’s mass immigration policy is now the key threat to Australia’s water security.
A new study by University of NSW scientists warns that climate change is reducing inflows into Australia’s water catchments, which will cause chronic water shortages as Australia’s population balloons:
“We are looking at anaverage of 20 per cent reduced reliability in the future across all the catchments considered,” said Ashish Sharma, a professor at UNSW’s School of Civil and Environmental Engineering, and an author of the report.
“While this might not matter a lot up north where you have lower demands compared to inflows, this is pretty serious down south where the demands are high and we are already seeing impacts of the drought,” he said…
Compounding the problem will be the likelihood that cities will lift consumption of water for parks, gardens and other uses.
“Because of that increased demand, you’ll see a greater reduction in reliability [of storage],” Professor Sharma said…
Professor Sharma said that, while authorities could find further ways to reduce demand, at some point a threshold would be crossed and governments would have to make bigger investments…
The mass immigration ‘Big Australia’ policy guarantees chronic water shortages.
According to the Australian Bureau of Statistics’ medium (panel B) projections, Australia’s population will swell by 17.5 million people over the 48 years to 2066, reaching 43 million people:
As shown above, all of Australia’s projected population growth will come from net overseas migration (NOM) – both directly as migrants step off the plane and indirectly as they have children (counted as ‘natural increase’).
The additional 17.5 million people will massively increase water demand at the same time as supply is reduced from lower rainfall and rising evapotranspiration rates due to climate change.
Put simply, the ‘Big Australia’ mass immigration policy is a fundamental threat to Australia’s water security.
The best thing our policy makers could do to safeguard the nation’s water supplies is slash immigration, which is running at around triple the historical average.
The New South Wales government recently announced plans to double the capacity of the Sydney desalination plant to 500 million litres a day. A 15 million litre a day plant is also planned for the Hunter region, while one as large as the existing Sydney plant could be built in the Illawarra region if water levels in Sydney dams continue to fall. These desalination plants have sparked concern about a possible lift in greenhouse gas emissions in NSW:
Independent MP Justin Field said other desalination works could add to the demand on the grid…
“Desalination is hugely energy intensive and will produce significant greenhouse gas emissions if powered by coal,” Mr Field said. *
“The new and expanded desalination plants currently being considered in Sydney, the Illawarra and the Hunter could consume as much as 615 gigawatt-hours of electricity a year.”
If all that electricity were to come from the state’s coal-fired power stations, NSW’s annual emissions would increase by some 615,000 tonnes of carbon dioxide-equivalent a year, or the same as adding 250,000 cars on the road, he said…
Let’s cut the bull. Australia will never meet its emissions target while it continues to grow its population by around one million people every three years via mass immigration.
The next chart on Sydney highlights the point. According to the ABS’ medium (Panel B) population projections, Sydney’s population will hit 9.7 million people by 2066, 5.1 million more than what would occur under zero net overseas migration (NOM):
That’s an enormous number of extra people consuming resources and emitting greenhouse gasses.
Moreover, with reduced projected rainfall and rising evapotranspiration rates, Sydney and its surrounding regions would need to build a battery of energy-sucking water desalination plants, which will necessarily raise emissions.
Therefore, as Sydney’s population almost doubles,so too will the number of buildings, driving emissions upwards.
Sure, the Government could attempt to power these desalination plants via renewable energy, but this would very likely shuffle the deck chairs and leave the rest of the state relying on traditional power supplies.
Immigration-fuelled population growth is unambiguously threatening Australia’s ability to meet its Paris Agreement emissions targets, in addition to straining its fragile natural environment.
The current droughts and fires should be a call to arms to stop this ‘Big Australia’ policy madness.
The Herald’s Nick Moir captures how dry Lake Burrendong is due to the drought affecting the state.
Just three years ago, the dam was at overflow-levels of 120 per cent, before devastating drought conditions set in.
Now there are fears the dam, which spans the Macquarie River, will run dry and leave towns without a water source. In some areas, that could happen soon: modelling shows Dubbo may run dry by midyear, while for Cobar, regular water sources may fail by September.
“It should be scary for a lot of people,” Cobar council general manager Peter Vlatko said.
“The commitment from the government is that we won’t run out of water. But the difficulty is that the Burrendong is at 1.6 per cent.”
The state government has promised Cobar will receive 80 per cent of its allocated water for 2020, Mr Vlatko said.
But old and faulty infrastructure has compounded problems, with a major pump failure in Hermidale late last year. Dubbo and Cobar residents have been placed on unforgiving water restrictions and miners have been told to save water.
An AGL hydroelectric station that normally uses run-off from the dam has also been taken out of action.
Meanwhile, local officials are scrambling to install additional pumps to extract water pooled below the dam’s usual outlets.
There are also plans to divert water from the Windamere Dam, nearly 200 kilometres away. WaterNSW is meeting landowners and may release up to 25 gigalitres in early February, according to a WaterNSW official.
Under the plan, water would flow via the Cudgegong River and into the Burrendong Dam.
WaterNSW will assess whether the emergency top-up is necessary after this weekend’s forecast rain.
But it’s unlikely the rain will raise the water levels at Burrendong significantly.
“The soil’s so dry at the moment so it acts like a sponge,” University of NSW water scientist Stuart Khan said. “When that happens it takes a significant amount of rainfall to generate run-off.
“If we have 40 or 50 mm [of rain] then we might expect some good run-off. But 50 mm is not going to fill the lake. I think you need something like 50 mm to even start generating run-off.”
WaterNSW agreed that “significant” rainfall would be required to make a difference to the dam’s levels.
In its current state, Burrendong Dam looks unrecognisable compared with during flood years. In 1990 and again in 2010, deluges filled the dam to overflowing, with the catchment at more than 150 per cent capacity.
Wildlife, included kangaroos, were stranded, requiring a rescue operation by boat.
The last year of flooding was 2016, after which levels began to plummet.
Now, with dam levels so low, tourism and recreation have dropped off in the area.
Codey Swadling, from outside Orange, grew up waterskiing on the dam.
“You look at the number of complaints that councils get [which] are people actually asking for trees to be cut down,” he said.
So even trees are not as simple a solution as you would think.
Thinking about the future
But people are getting there — it’s about generational change.
Councils are spacing out streets, they’re using reflective colours,planting trees, using heat sensors, holding design competitions, installing water features — these are just some of the things the west are doing to fix the city.

“You don’t have to have to have an argument about global climate change or anything,” Mr Bali said.
*“Manmade climate change in the Sydney basin will have an effect, there is no question about that. *
“So essentially how do we accommodate our health systems to recognise that there are these issues and apart from just building hospitals, which is an end product … we want to avert the illness.”
What is the urban heat island effect?
The urban heat island effect is caused when a metropolitan area is significantly warmer than surrounding areas due to human activity.
The biggest cause of it is hard surfaces, like roads, footpaths, roofs, as well as buildings.
They absorb the sun’s heat to send it rippling throughout the surrounding areas.
Jonathan Fox, a researcher at the UNSW in the faculty of built environment, looks at how to design buildings of the future.
He said the science is unequivocal — heat is a problem.
“We live in an urbanising world so more people live in cities, the cities are getting bigger and cities are getting hotter,” he said.
“And then we have a consequence of urbanisation, which is commonly referred to as the urban heat island effect.”
If you’re in a city today and you’re feeling hot, look around and you’ll start to notice all the things that make the heat worse, which add to the urban heat island effect.
These are things like dark concrete, no trees for shade, houses with dark roofs, endless paved roads as far as the eye can see.
“[The urban heat island effect] has been called inadvertent climate change, and there’s no doubt that the way cities have been constructed in the past, without knowledge of the climate effects of design, have exacerbated the overheating problem in cities,” Mr Fox said.
One of them is pretty simple. Lodged in the branches of different tree species are 20 temperature sensors — tiny little pieces of plastic stuck to tree limbs hidden from view.
It’s called Smart City project and is being run in cooperation with Parramatta parks and reserves workers.
“So it’s a really low tech, really flexible and easy way for us to monitor the temperature in the park under each of the tree species,” Mr King said.
“It basically logs temperature regularly for three months until the battery runs out and then it just becomes a USB stick.”
The council also have two water parks in operation — basically playgrounds covered in giant sprinklers.
Along with simple projects such as those, Parramatta Council regularly run design competitions for architects, asking them to rethink the design of buildings — like including awnings, reorienting the building’s outlook, and changing the materials
“Aboriginal and non-Indigenous Australians all understand that by lowering a flag we acknowledge that something has died or that something is dying. It is a symbol of mourning. There are so many people who are feeling anguish.”
An Aboriginal woman from Victoria is hoping that First Nations people and organisations around the nation will join her university in flying Indigenous flags at half mast, to acknowledge the grief Aboriginal people are feeling at the destruction of Country from Australia’s ongoing bushfire crisis.
Associate Professor Gabrielle Fletcher is a Gundungurra woman from the Blue Mountains of New South Wales. She’s also a Professor in Indigenous Studies and the Director of the Institute for Koorie Education at Deakin University in Melbourne.
“To lose Country, in this way, is a particular grief for Aboriginal and Torres Strait Islander people. It’s a messy grief,” Associate Professor Fletcher told New Matilda.
“It’s more in sorrow than anger, it’s mourning. You could say it’s ‘Sorry business’ in a way.
“As a collective, this symbolic gesture may provide somewhere for all Australians to leave parts of this despair.
“It’s also a reflection of the immense grief of guilt where we feel a kind of irresponsible helplessness – our sense of the abandonment of our cultural obligations to Care for Country.”
Deakin University is already flying the Aboriginal flag at half mast today, after a request from Associate Professor Fletcher this week to the Vice-Chancellor, Professor Iain Martin, with the gesture receiving “overwhelming” support from Deakin faculty and students.
Professor Fletcher is hoping it might spread across the nation, and that “these lowered symbolic fabrics become the message sticks for urgent change”.
“Aboriginal and non-Indigenous Australians all understand that by lowering a flag we acknowledge that something has died or that something is dying. It is a symbol of mourning. There are so many people who are feeling anguish.”
Assoc Prof Fletcher said the scale of the loss felt by First Nations people was enormous, and it wasn’t just restricted to the land and its animals.
“Country moves beyond landscape, allotment, vista or wildlife as stand-alone components. It is also place, Ancestors, shadows, mist, warble, maps and vapour,” she said.
“When Aboriginal People lose Country to this scale we lose Knowledge, Ways, Forms, Spirit and Healing – these are a complex interconnection, where everything has its place to teach, feel, show and speak.
“With each loss we slip further away from understanding who we are, and how we fit – this is the ultimate death in many respects.”
Assoc Prof Fletcher acknowledged there were some positives to come out of the fire crisis, beyond waking people up to the realities our nation faces.
“People are starting to recognise and acknowledge the validity and value of Indigenous Knowledges, and ways of knowing, being and doing. It’s been an uncomfortable discovery for some.”
Assoc Prof Fletcher hopes that other organisations follow suit and lower their Aboriginal flags in the aftermath of the bushfire emergency.
“I think this action symbolically describes the collective realisation that we’ve lost so much more than what can be seen and is a true wake-up call.” Professor Fletcher said.
“On behalf of the Institute of Koorie Education, I thank Deakin Vice-Chancellor Professor Iain Martin for his support in this unprecedented gesture.”

At least 80% of the Blue Mountains world heritage area and more than 50% of the Gondwana world heritage rainforests have burned in Australia’s ongoing bushfire crisis.
The scale of the disaster is such that it could affect the diversity of eucalypts for which the Blue Mountains world heritage area is recognised, said John Merson, the executive director of the Blue Mountains World Heritage Institute.
The data is based on a Guardian Australia analysis of areas burned in New South Wales and Queensland and was confirmed by the NSW government.
Guardian Australia reported in December that 20% of the Blue Mountains world heritage area had been affected by fire in the early months of the crisis.
Four times that amount has now burned in what Merson said were fires of a scale that “has never happened before”.
“This is totally, totally unique. As everybody keeps saying, it’s unprecedented,” he said.
The Blue Mountains world heritage area covers one million hectares of national park and bushland and is dominated by temperate eucalypt forest.
The area is renowned for the diversity of its vegetation and is home to about a third of the world’s eucalypt species.
While most are fire-adapted and can regenerate, many of the species depend on long intervals between fires, Merson said.
“We had a very large fire in 2013. It’s only six years after that,” he said.
“The eucalypts can be very badly reduced in diversity if fires come through in too short and intense intervals. Their numbers will virtually collapse.”
He said the full impact on tree species and wildlife would not be known until more assessments were done as fire grounds became accessible.
But there are concerns about the effect on breeding and feeding habitats for species including the spotted-tail quoll and the brush-tailed rock-wallaby.
The fires have also burnt swamp communities that release water slowly and are important water resources. They flow into streams that feed into Sydney’s water supply and provide water for wildlife.
It was revealed this week that a rescue mission by NSW fire crews was able to save the only known natural grove of Wollemi pines, so-called “dinosaur trees” that fossil records show existed up to 200m years ago.
Merson said the fires had entered areas that had not burnt previously and the need for the rescue mission was indicative of the intensity of the fires in the region.

Graham said his area had experienced some rain in recent weeks but there were now concerns that sediment washed into the Bellinger River has affected the food sources for the critically endangered Bellinger River snapping turtle.
A spokesman for the NSW Department of Planning, Industry and Environment said understanding the impact of the fires on both world heritage areas was a priority.
“Analysis will improve as the forests becomes safe to enter and the smoke clears, enabling accurate satellite and aerial imagery to help guide our assessment and on work on ground,” he said.
He said both regions contained a mixture of forest types, some of which was adapted for fire, but others that were more sensitive to fire, such as dense rainforest.
Jess Abrahams, the nature campaigner for the Australian Conservation Foundation, said climate change was hitting Australia’s world heritage areas “very hard”.
“We have witnessed consecutive years of devastating coral bleaching on the Great Barrier Reef, while global heating has been described as a catastrophic risk to the Wet Tropics and Shark Bay world heritage areas,” he said.
“It’s really upsetting to see how much of the Blue Mountains world heritage area has been burnt.
“This is a place many Australians know and love. It has significant Indigenous cultural values and is home to a number of rare and threatened species.”

TEMPERATURES rise dramatically in urban environments during heat waves from the west.
Compounded by thermal mass and poor city design.
PENRITH has become hotter because of the thermal mass from overdevelopment … the “heat island effect”.
Collecting not only pollution but all the heat from the entire city of Sydney in a basin bounded to the east by the Pacific Ocean and to the south, west and north by elevated terrain.
AND … it is evident that Penrith is becoming a thermal mass wasteland due to the higher density rezoning, motorways, airport construction along with the removal of trees (less than 6% of the Cumberland Plain Woodland remains!), and loss of farmlands …. vegetation!
SUSTAINABILITY would be about adapting … following this disaster of overdevelopment … some might go as far to say that Sydney needs to be bulldozed … redesigned once the awfulizers, the mafia of developers are done with Sydney and run off with Billions in their pockets.

BUSHFIRE and NATURAL HAZARDS CRC
“Heatwaves are dangerous and have killed more people in Australia than all other climate related disasters combined.
Urban environments are considered especially vulnerable to heatwaves due to the Urban Heat Island effect. Increasing death rates from heatwaves are predicted to become one of Australia’s most detrimental impacts of climate change (IPPC 2014) with major implications for emergency services and public policy development.
The catastrophic dimensions of heatwave mortality are not spread evenly across society but are concentrated among specific population groups. Older people, especially women, are overrepresented in heatwave related excess mortality statistics internationally.
Using a critical perspective, this paper aims to present a literature review exploring current research on social vulnerability of older women during urban heatwaves. It will illustrate how heatwave vulnerability is largely socially constructed through the intersection of deeply entrenched gender inequality with systemic socio-economic disadvantage.
The review will highlight the need for heatwave intervention to be guided by a social justice perspective, to avoid older, poorer women becoming the shock absorbers of the climate crisis.
This paper is part of my PhD research project at Monash University:
‘Denaturalising heatwaves: gendered social vulnerabilities in urban heatwaves and the use of public cool spaces as a primary heat health measure’. The research has ethics approval.”
