Dear Moody's

Dear all

I am recording a series of Dear Moody's Videos.

I believe that there is so much private infrastructure being installed and that this is the reason why we don't have electricity load shedding and water load shedding. See http://bit.ly/dearmoodys

I need more awareness. Please watch and share.

Cape Town Water Crisis: How to cover our dams

A new year, a new idea :

Imagine if we could cover all our dams?

So we can!!

We can put systems in our pools to make our pool water drinkable.

We can cover our pools. Our water bill dropped by more than half when we installed our pool cover in 2015. "Power Plastics pool covers reduce evaporation by more than 98%". From their website. I don't work for them.

And this can even be done at Newlands Swimming Pool and our other Municipal Pools.

So:
1) If you have a pool cover, AND
2) If you invest in a system that makes your pool water drinkable, AND
3) If you sign an agreement with the City to allow them to take out whatever you put in from 1st January 2018 onwards ...

Then: You can fill your pool using potable water. And you can install your swimming pool water management systems before tax and before VAT.

If we fill our pools and keep them covered and clean, we can reduce our dam evaporation by 98%. Using Embedded Water.

Happy 20 18. Let's think differently.

PS: I'm sure there are people on this group who know:
1) how many pools there are in Cape Town.
2) how many litres of water there are in these pools.
3) what the evaporation is from the dams.
4) how much water can be saved, and what this system will cost.

Cape Town Drought Disaster

We have been spoilt. Now we must get back to basics. And relearn who we are. And not depend anymore.


Cape Town: February 2018?



A documentary about Water in Cape Town!!


There is a very good chance that our water sources will run dry in February, 2018, less than three months time! We should be doing everything possible to avert this disaster, even if it means temporarily drilling into the aquifer or sinking well points, and BTW, many houses have had well points for decades in this City and in many others, without anyone telling us off.

Of-course large scale desalination is still required and the City's attempt at adding 20 million litres a day to fix the problem is really too little too late.

We need 2.4 billion litres of water a day to be considered world class. Before the crisis we were using 1.2 billion litres of water a day. Now, two years later we have already halved our water consumption and we are under 600 million litres a day and now the council have asked us to reduce our consumption to under 500 million litres a day. We will get there. And we are all learning a great deal about how to conserve water and to go back to the days before government told us that they could support us with cheap food, cheap electricity, cheap water and cheap transport. We have millions of years of doing things ourselves before governments turned up 80 years ago and started spoiling us.

And Israel has shown that desalination can be done at R7.50 per kL and most people who actually pay for water in Cape Town already pay this.

We have been spoilt. And now it is time to clean ourselves up and do things ourselves, again.

My recommendations to dramatically speed up investment in getting solutions on the ground:

  1. Allow private people to invest in all water and electricity (we still have an electricity crisis) and sewerage infrastructure before tax and before VAT.
  2. Incentivise people to convert their pools from chlorine and salt to oxygenated pools that contain drinking water.
  3. Incentivise people to not use water from the grid. Adding a water Levy is counter to this.
  4. Start a crowd-funding campaign to raise money for a large scale desalination plant in Cape Town
  5. Create a database of preferred supplies.

Simple Solutions Exist : Letter in the Cape Times on 16th November 2017

I wish to point out to our government that even if our dams were full, we would still need desalination.

You see, the population has more than doubled in the past 20 years. Our dams are still almost the same size, probably smaller, due to silting, even with the new Berg River dam.

And our dams were built 30 years ago or more because we are in a drought area. This is not news!

And they were built to give us five years of water in the event of a drought. Now they give us two years of water. So assuming the dams can give us half the water we need, then we should already be desalinating 600 million litres of water a day.

In the winter / rainy season, we should not be using any dam water. By the end of winter, all our dams should be full. And all our embedded water systems should be clean and full. This includes swimming pools, all backup systems and aquifers. And our swimming pools should contain drinking water, also doable.

I've met someone who was working on desalination for Cape Town in 2010. The project was shelved because it rained. But as I have already said, this is so incredibly short sighted.

Solutions are at hand. They are modern, simple and inexpensive. And they should be implemented as soon as possible.

PS, not in the paper: The latest in desalination technology can be found at Sorek. And water at about R8 per kL is cheaper than a lot of us are paying in Cape Town, especially with tiered water rates, and the top rate being over R300 per kL. Spring water can cost R12 for a litre.

Windhoek City Announced Water Crisis

Just a day after the City of Cape Town announced the start of water rationing, pretty much by the possible doubling of water prices, Windhoek City announces water crisis.

Pool covers mandatory. Pools not allowed to be filled. I agree with the pool covers, but I think pools should be filled. Reason: just like embedded electricity generation is critical to the functioning of our grids, so embedded water storage will also be critical to our ability to survive as a species.
