Our way of living on earth has resulted enourmous environmental and ecological problems, which they are affectnig our habits and our lives in return.
Global warming and drought as a consequence of that is changing the face of the earth. Leakages from sewer systems and raw sewer drainage into lakes from treatment plants for any reason is polluting our ground waters and lakes. Huge amount of water loss in urban areas results in too much waste and mutiplying the damages of other infrastructures that again result in mor polution and increase risk of living in cities.
Sinkholes in cities are not an unfamiliar event and even one of them has a huge effect on public to feel insecure. disruption of service to critical places like hospitals would bring grave consequences.
Sometimes little mistakes causes big damages and our hope is to stop the mistakes in their early stages or proactively fix issues with less cost .
Water loss and Related Risks
Old cities like Toronto and Montreal have around 20-30% water loss in their distribution network it means that one in each four volume of the water that is pumped, never meets the other side of the pipe and is lost in between.
This means a huge energy loss to keep water pressure in an acceptable level. This Energy is not used just to push the valuable water out, but also it causes washout of soil around it and damages other infrastructures like sewer system, storm water canals, and asphalt.
A broken sewer results in leaking sewer into the ground water with a support of a running water which makes the dissemination of contaminats much easier.
The wash out of soil sometimes causes catastrophic events such as sinkholes which traps people, vehicles and makes public feel insecure.
Service disruption in hospitals would affect sick people and events like this surprise everyone and are costly to people at risk and to the others that are out of such events. Cities have increased their rates since 1980s with a rate higher than the consumer price index and it is still continuing because the only solution to the old infrastructure is replacing all the pipes, which is not true.
We have worked on a solution that shows 85% of the water main breaks happens only in 3% of the network in the city of Kitchener. This percentage might be different for other cities based on the existing condition of their network, although there is a clear message that the cost of maintenance is much less than what is happening and the number of breaks that are expected should be less than half of what we are experiencing in our cities and it means millions of dollars of savings every year.
Lakes Pollutions and their Sources
Lakes pollutions are usually considered to be the consequence of farm land contaminations or overuse of fertilizers.
During Aqua Hacking Waterlix processed satellite images to identify areas that are mostly affected by algae bloom and the result were intersting and were confirmed with other information.
Majority of areas showing algae bloom were near oversized cities and near and close to their waste water treatment plants or rivers that were passing through the cities and urban areas.
The other fact was that Toledo, Detroit and Cleveland were the top population losers in the united states. These oversized cities have less budget to address issues in their water sewer network and this would be expected to be one of the reasons of algae bloom in lake Erie.
The picture on the left is the area near pickering and Rouge river. The flow of water passes through the city, although when entered into the lake you can trace the algae bloom around the area near river enterance to lake Ontario.
It is urban sewer leakage and other contaminants that are washed out and their flow is entered into the rivers and end up the rivers.
Waterlix is determined to provide a service to trace the algae bllom changes in the great lakes and hopefully other lakes near big cities and identify rapid changes in algae density and report it bi-weekly in Views&News section under Lakes Category.
