Integrating water supply, sewerage and stormwater in the human environment to conserve ecology is a design choice that comes with real and substantial costs. The benefits – if we can afford them – are clean water and vibrant environments.
Building carbon stores in agriculture and forestry soils and biome through management is key. It has been declining – since the advent of Holocene technology apparently – but more in the last century. More than science it needs conservation agriculture and polycentric governance of the global commons.
1.1 Hydrological Cycle.
There are a few ocean influences on Australia. Depends on where in the country.

Looking beyond climate dogs – cooler and – in Australia wetter – in natural variability may be possible.

Eole water from air
The earth’s atmosphere is packed with moisture. It is a huge freshwater reserve: 13,000 km3. Eole Water has created an innovative technology which is able to turn this moisture into drinking water.
This is done using a condenser with a moisture exchange surface which is one meter wide and five kilometers long. It is equipped with a revolutionary “food safe” stainless steel quality alloy, especially adapted to producing drinking water. It can sustain the water creation process for decades, without risk of corrosion.
The water then flows through a five-tier water treatment system, including an ultraviolet filter, in order to make it perfectly safe to drink. The quality of water collected exceeds the drinking water standards required by the World Health Organization.
The water production machine can collect up to 1500 liters of water a day depending on the climate.

Ceramic Water Filtration
From the annals of the astonishingly simple and cheap.
Locally manufactured ceramic filters have traditionally been used throughout the world to treat household water. Currently, the most widely implemented ceramic filter is the Potters for Peace
design. The filter is flowerpot shaped, holds about 8-10 liters of water, and sits inside a plastic or ceramic receptacle. To use the ceramic filters, families fill the top receptacle or the ceramic filter itself with water, which flows through the ceramic filter or filters into a storage receptacle. The treated water is then accessed via a spigot embedded within the water storage receptacle. The filters are produced locally at ceramics facilities, and then impregnated with colloidal silver to ensure complete removal of bacteria in treated water and to prevent growth of bacteria within the filter itself. Numerous other locally-made and commercial ceramic filters are widely available in developed and developing countries. http://www.cdc.gov/safewater/ceramic-filtration.html#economics
Filter Straw and others
The straw filter is made from durable plastic approximately 10 inches in length and 1 inch in diameter. The internal components include membranes, iodized crystals and active carbon, which removes the iodine taste and medium-sized bacteria and is effective against waterborne bacteria and viruses, such as typhoid, cholera, E. coli, dysentery and diarrhea. The two-stage filtration system reduces harmful particles, from 125 micron down to a minimal 15 micron.
Sewerage
Porous Pavement 1
In urban environments, impermeable surfaces (streets, footpaths, rooftops etc.) dominate the landscape, preventing rainwater from following a natural cycle of absorption. As much as 75-80% of the rainwater runs into stormwater/sewer systems carrying contaminants from the air and roadways. This water flows untreated into lakes, rivers and harbors. In some cases, it may cause overflows of sanitary sewer systems, causing the dumping of untreated sewage (combined sewer overflow) into our waterways.

Rocla Up-flow Filter
The Rocla Up-Flo™ Filter is the most efficient high rate stormwater filtration technology available for the removal of sediments, nutrients, metals and hydrocarbons. As the industry’s only fluidised bed up-flow filtration technology, the Up-Flo™ Filter provides a higher level of treatment of stormwater runoff, a higher rate of filtration, longer life of filter media and a longer maintenance cycle than other filter systems.
The Rocla Up-Flo™ Filter is available in multiple configurations, has a small footprint and removes >90% total suspended solids (TSS) with a mean particle size of 20 microns.
