The continue II. for Dana
Water University – a program of education in the spirit of New Water Paradigm and integrated management of water sources (with the stress on urban environment) will be started in partnership with University of City Presov. The target group shall consist of managers, developers, architects, decision makers, local leaders and all kinds of stakeholders in water management. The goal is to provide them education in sustainable water management, renewal of water balance on their land, minimizing risks of water related natural disasters and not least about climate aspects of water management.
We provided projects in Slovakia only, so far. But we spread the idea also abroad, where it “caught fire” in some cases.
We claim, that every roof and every yard is a micro watershed. Costs for a small house depend on what we want to achieve. Anyway, costs to harvest rainwater and infiltrate (and evaporate) water can be close to zero in the case of availability of proper depressions and infiltration conditions in vicinity of the building. If not available, simple earthworks to stop runoff and create waterholdings are not expensive and they don’t require much manpower either. Gravel fillings, which are not necessary, but can upgrade infiltration and storing capacity, are manageable also. Simple computation can show that the investment would return relatively quickly.
As far as we know, the Law on Protection of Water Cycle has been neither discussed in any legislative body yet, nor implemented. We try to seed the idea, as we lately did in European Parliament and European Commission. There is still a very long way to go.
Hope these answers were at least a bit useful.
Best regards,
Michal Kravcik

Projects - Cool City, Blue Schools and Water University are starting in the city Presov (about 100.000 inhabitants), Eastern Slovakia. Project Cool City is the key demonstration of a new water culture in urban environment. It aims to build a complex integrated system for keeping rainwater in the urban environment, and to use such water for improving the urban environment’s microclimate. Rainwater in the city shall not be drained from roofed or paved areas to sewage. Instead, an integrated network of waterholdings will be created. It will collect rainwater from objects, roads and parking lots. Rainwater shall be infiltrated into soil and subsoil, accumulated under and on the ground, in vegetation, tanks, ponds, etc. Its evaporation, which will cool the city, will be encouraged from trees and other vegetation of parks and plots, from open water surface of ponds and from fountains. Green walls and roofs of buildings will fulfill air-conditioning role too. By keeping rainwater in the city environment, we can as well save citizens´ money paid for drainage of rainwater and make more water available for them.
Blue Schools – this is a project of a model water management within a system consisting of school building and school plot. Rainwater harvesting, water cleaning and recycling shall be applied. The project shall mean significant decrease of costs for external supply of water. It shall be as well significant for pupils, teachers and parents as educational tool towards new water culture.

Dear Dana,
Thank you for your questions. I’ll do my best to respond them.
“New Water Paradigm” (NWP) was released in September 2007. There was not much time to take concrete tangible actions or improvements based on it. Nevertheless, Association of Towns and Municipalities in Slovakia (member organization for 96% of municipalities in Slovakia) adopted our basic principles (like comprehensive program of rainwater conservation on the land) in its strategic document Strategy on Prevention Against Floods. Nowadays, the Association is discussing a document about integrated water management based on NWP. There were tangible actions in the spirit of NWP before it was fully articulated and released. Within "Blue Alternative" plan in mid 90-ies at Tichy Potok, East Slovakia, we constructed a number of catch basins to show there are alternative ways to acquire water. Within our project „Water Forest“ in 2005-2007 in High Tatras, Slovakia, about 7.000 waterholdings with potential volume 12.000 m3 on approx. 80 hectares were built. Researchers record that fauna and flora are much better off there than on comparable plots, where measures were not applied.
The continue in follow input.

Hello Michal,
It's great to have your entry in the competition. What concrete tangible actions have taken place or improvements in water usage based on your NWP? Could you please give some more examples on your projects - Cool City, Blue Schools and Water University? These sound interesting and I would love to know more about what they are all about. Can you give more of a description of the individuals you have served? What countries, number of people, demographics of the people, etc? You mention that each roof could have a microwatershed. How much would this system cost for a small home?

Lastly, you mention the Law on Protection of Water Cycle. Has this law been implemented anywhere else? What work are you doing to see this law put into place?
Thank you for all your responses!

Thank you very much for your kind words.

We see three key areas to get additional support for our paradigm: 1/ Theoretical - to build up solid scientific theory behind it; 2/ Practical - to show on real-life applications that it is functional; 3/ Popular - to spread the message to broad population. Last but not least, we prepare presentation of the paradigm on Expo in Zaragoza (via conference + publications). We seek allies for all three areas.
Everybody is welcome to join the effort, including you :-). We have a vision of expansion too, but we definitely don´t want to have monopoly on innovation - vice versa, we want it to be applied by everybody and everywhere.

Best,

Michal

Hi Michal,

Congratulations on submitting one of the few proposals that seeks to address some of the root causes of the water crisis rather than just the symptoms. Please provide some additional information on how you hope to gain additional support for your innovation and how you hope to expand.

It is far more important to keep water safe, available, and affordable for all than to try to keep the price "Cheap" for all.

Regards,

David
