Urban Discussions

Urban at the 8th World Water Forum

Fast growth of cities increasingly requires the adoption of sustainable and integrated processes for urban waste and water management. Water scarcity in drier times, as well as excess water in in rainy periods, directly affect the dynamics of cities and people's lives, leading to diseconomies and major losses, which require urgent measures. Despite the increasing investments in promoting its rational use, the use of water in urban environments generates significant and increasing volumes of effluents, whose treatment and final destination is of paramount importance. In addition to that, the existence of under-infrastructured settlements – like slums – without minimum access to water, drainage and sanitation, is still a reality to be faced. In this scenario, methodologies for water treatment and reuse and waste recycling, associated with campaigns to reduce consumption are gaining importance to improve life conditions in cities.

Urban - 1st Discussion Feb - Apr 2017

Join the Discussion

The 8th World Water Forum will have the question of water in cities as one of its central themes, focusing on integrated urban water and waste management. In order to reach that, three topics have been set to comprise the debate questions under Urban. The following topics should split into Thematic Sessions and other debate stages during the 8th World Water Forum in 2018:

  1. Water and cities
  2. The circular economy – reduce, reuse, recycle
  3. Treatment and reuse technologies

Considering the above topics about Urban:      

  1. What are the major challenges under each topic that concern civil society and communities and need to be raised for debate during the 8th World Water Forum?
  2. How those challenges apply to problems in your city, community or neighbouring surroundings?

Your feedback is going to support the organisation instances of the Forum in the definition of Thematic Sessions and other opportunities for debate during the event.

Vou ficar com a economia circular e tecnologia de tratamento e reuso, a região onde vivo somos bem servidos em água e qualidade, o que faz com que o incentivo de tratamento e reuso seja mínimo, apesar da cobrança para o uso de água de poço artesiano o valor é bem baixo, compensando mais pagar para consumir do que propor um tratamento e reutilizar. Sem falar no momento de crise que estamos vivendo a questão ambiental infelizmente ficou de lado, sendo como justificativa para até o descumprimento de legislação. Passamos fases de racionamento onde meios de comunicação foram usados para racionar a água, principalmente devido ao acidente ambiental que aconteceu com o Rio Doce, mas isso acabou, as pessoas estão desperdiçando ainda mais. Plantar a sementinha não é fácil.

Bonjour J'ai participé au 6éme Forum Mondial de l'Eau à Marseille. Cela a t il fait bouger les choses NON

J'ai participé à la COP 21 à Paris: j'étais le seul professionnel à proposer un REEL traitement d'épuration des eaux usées. Cela a t il fait bouger les choses NON

J'ai participé à la COP 22 à Marrakech : j'étais le seul professionnel à proposer un REEL traitement d'épuration des eaux usées. J'ai pu constater qu'effectivement le le défaut de traitement d'épuration des eaux usées était un réel soucis. Mais cela va t il faire bouger les choses.?

Hello I attended the 6th World Water Forum in Marseille. Has it made a difference no

I attended the COP 21 Paris: I was the only professional to offer real treatment of wastewater treatment plant. Has it made a difference no

I attended the COP 22 in Marrakech: I was the only professional to offer real treatment of wastewater treatment plant. I have seen that actually the failure of treatment of wastewater treatment plant was a real concern. But it does it make a difference.?

Today all organisations in the world run and seek innovation when the INVENTION is totally prohibited. I put challenge anyone shows me a folder which contains a line that defines that the invention is a priority

Aujourd'hui toutes les organisations au Monde courent et cherchent l'innovation quand l'INVENTION est totalement interdite. Je mets au défi quiconque me présente un dossier dans lequel on trouve une ligne qui définit que l'invention est une priorité

Thanks, Mohammad. You suggest to share  examples and practices of efficient urban management with innovative financial and technologies. Also, what would be your ideas and main point of concerns that you think urban leaders from countries should discuss in world water forum?

My ideas and main point of concerns: Our atmosphere contains about ten times more fresh water than all the combined fresh water rivers on the surface of the Earth. Urban leaders should be aware! A small fraction of that atmospheric water which condenses as clouds falls as rain. Water provision is a fundamental challenge in many human settlements today. The risks associated with water shortage increase as the limited freshwater resources gradually diminish. The Organisation for Economic Cooperation and Development have estimated that by 2030 47% of the world’s population will live in water-stressed regions (OECD, 2008).

For instance, the Mediterranean Region is experiencing significantly lower than average rainfall, with severe impacts on rainfall-dependent settlements, industries and the environment. Regarding drinking water, about 14 million people in Europe do not enjoy access a basic drinking-water source, and 62 million people do not have access to piped water on premises. Seven out of ten people without access to a basic drinking-water source live in rural areas. Inequalities exist in access to drinking-water and sanitation services, where rural dwellers and the poor are the most disadvantaged (WHO European Region, 2015). The current shifts in rainfall patterns around the Mediterranean coast are likely to continue, aggravating current localised water shortages. 

Alternative technologies: The collection of fog water is a simple and sustainable technology to obtain fresh water for irrigation and drinking for human and animal consumption. In regions where fresh water is limited and fog frequently occurs, it is feasible to set up a passive system for fog water collection. The screen is perpendicularly exposed to the winds and fog is pushed through the mesh by the wind. Natural aerosoles are trapped on the mesh and form larger droplets, which drip down passing into a water storage tank. Fog water collection rates vary dramatically from site to site between 3 and 10 l/m²/day during yearly averages of fog occurrence.

Sustainable business model: Whilst conventional fog technology is proven and has been used for several decades, there are new questions to be solved. The problems are (1) the business model and (2) the high cost of production. In most cases, the users of planar fog catchers are unable to repair and maintain both frame and canvas, which is deteriorating over time, until it is unusable. In order to reduce production costs, advanced design must be used, textile efficiency and yield must be improved; textile materials and lightweight constructions should be developed more economically to take advantages of local resources available.

Examples and practices of efficient urban management with innovative financial and technologies: Apart from the experiences developed by NGOs and university experts worldwide, innovation requires an urgent attention. The main design aspects to take into account are: a. Climate: Wind speed and direction, air temperature, radiation UV, fog water content, relative humidity; b. Topography: Crestline, altitude, slope, clearance (no physical obstacles nearby), upwind orientation; c. Structure: screen ratio (height length); height from ground, volume geometry, frame type; and d. Textile: pores, patterns, spacing, water-repellence, coating and colour.

The denser the fog, the greater the water. In order to seek sustainable sources of fresh water, innovation should focus on design-based industries approaches. My inventions FOGHIVE & AIRDRIP represent an innovative water enhancement that offer autonomous water management and sustainable living in waterless habitat by developing lightweight 3D fogtraps that harvest fog water for drinking, agricultural irrigation and ecological restoration in collaboration with local industry, social entrepreneurs and stakeholders.  The novelty of my products lies on: a. Shape: The best screen ratio is found in polyhedral forms with hexagonal footprint (Suau, 2010, 2011, 2012). Both form and orientation geometrically response to the muti-directionality of winds.  Like an extruded wind rose plot, this wind-responsive innovation augments the capacities of fog catching six times more than conventional planar devices. b. Structural lighness: Lightweight space-frame demonstrated great stability against strong winds. It only requires two people to mount and dismantle. c. Advanced textiles: go for white mesh with high porosity. The result is at least 6 times for water colelction than any traditional solution.

Hello everyone,

Thanks everyone for their contributions in the first week of discussion. It was nice to see many involved from different spheres and bringing out their professional and local experience. One of the main points discussed was how financial sustainability in urban water services can be maintained which is not the case in many countries. Also, points were raised forward to have investments in infrastructure ( pipes, meters) and technologies like fog collector, sanitation systems along with increasing the capacity and management of urban local water bodies. 

I think going forward in the discussion, it would be interesting to hear about  examples and practices of efficient urban management with innovative financial and technologies. Also, what would be your ideas and main point of concerns that you think urban leaders from countries should discuss in world water forum.

 

Thanks

However there is not significant design progress among planar/conventional fog collector, so 3D fog collectors are the alternative water technology that can increase yield, offer autonomous water harvesting and management in waterless habitats. We have to put special attention to the development of advanced textiles and building materials with affordable manufacturing and shipping solutions.

Ricardo de Sousa Moretti's picture

Ricardo de Sous... said:

Acredito que uma importante temática a ser debatida no evento é a das formas de remuneração e de cobrança pelos serviços de saneamento.  Em parte significativa das metrópoles dos países mais pobres está presente o desafio de racionalização do uso de água (gestão de demanda) e de tratamento dos esgotos. Como é predominante a remuneração dos serviços pela quantidade de água consumida, existe uma tendência preocupante de que as empresas de saneamento privilegiem a busca de novas fontes de água e que ampliem a oferta e a venda de água, mesmo que as novas fontes estejam distantes e façam ampliar a pegada ecológica do processo. Por outro lado, na ótica financeira dessas companhias não é considerado um bom negócio o tratamento de esgotos, em especial se a companhia recebe a partir da mera coleta dos esgotos, ou seja, sua receita é a mesma quer faça ou não faça o tratamento de esgotos, que é o caso de São Paulo, por exemplo. Por outro lado, a forma como hoje se cobra do usuário pelos serviços de saneamento carrega diversas distorções e injustiças. Exemplo dessas distorções é a cobrança da quantidade mínima de 10000 litros por mês, que afeta as famílias pequenas e pobres. Outra distorção ocorre nas residências múltiplas em um único lote (casas de frente e fundos, ou  puxadinho, na linguagem popular), que pagam valores muito mais altos por m3 consumido.

Outro tema que considero relevante é a das estratégias para garantir suprimento mínimo de água, em situações de crise de abastecimento, ou seja, sobre a formulação de planos de contingência. O cenário observado na crise de abastecimento que atingiu SP em 2014 a 2016 mostrou como estamos ainda despreparados para estas situações.

I believe that an important theme to be debated at the event is about the form of remuneration and the charge for sanitation services. In a significant part of the metropolises of the poorest countries, there is the challenge of rationalizing the use of water (demand management) and sewage treatment. Since services are predominantly remunerated for the amount of water consumed, there is a worrying tendency for sanitation companies to favor the search for new water sources and to increase the supply and sale of water, even if the new sources are distant and if it increases the ecological footprint. On the other hand, in the financial perspective of these companies, the treatment of sewage is not considered a good business, especially if the company receives from the mere collection of the sewage, that is, its revenue is the same whether the treatment of sewers is done or not done, which is the case of São Paulo, for example. Also the way in which the user are charge  for sanitation services shows some distortions and injustices. An example of such distortions is to charge for the minimum amount of 10.000 liters per month, which affects small and poor families. Another distortion occurs in multiple households in a single lot (front and back houses) which pay much higher values ​​per m3 consumed.

Another topic that I consider relevant is the strategies to guarantee minimum water supply, in situations of supply crisis, that is, on the formulation of contingency plans. The scenario observed in the supply crisis that hit SP in 2014 to 2016 showed how we are still unprepared for these situations

Mohammad Faiz Alam replied:

Hi Ricardo,

You have raised a very important point of having financial sustainability in the operations of water . For example, in India most of the urban municipalities are not financially sustainable which reflects in poor services and dying infrastructure. Public private partnership is evolving but still a long way to go because charging for water is not the norm here and gets mixed with politics.

What you mention is little different I think but boils down to the policies. What you think should be the role of govrnement in urban water services. As a provider or a regulator ? How should government make the sustainable management and circular economy mainstream and can encorage service providers to do so ?

Thanks

Hello everyone, especially to Artur!

The lack of water in cities for a prolonged period is really a very unpleasant fact. Keep in mind that in Brazil municipalities are responsible for sanitation services, and when local governments cannot predict and act properly in times of water crisis we deal with very serious issues. Certainly, the the aim is that investments were made in works that would make possible a great security in the public supply so as not to depend on the reaction capacity of the mayors. However, many municipalities do not have sufficient resources for investment, what makes the risk of shortages very high in cities with disorderly growth. To make matters worse, large losses are still observed in the distribution of treated water in Brazil.

In cities such as Brasília and São Paulo, where average annual rainfall is above 1,300 mm, people normally do not feel the need to have large reservoirs in their homes or buildings to store water. The reservation usually came down to the volume needed to meet daily use. In the crisis that occurred in São Paulo, the first reaction of the residents was to arrange new reservoirs to increase accumulated volumes. The population rushed to acquire manufaturacted cisterns, which began to lack in stores, causing many to improvise using plastic or metal containers of low capacity.

The fact described shows that reaction to crisis tends to be irrational, and with many people lacking the view that limiting the reaction to this but with water not being saved, we will keep having to rationalize and the most impaired will be the poorer. What's worse is that population´s improvement in perception is very slow.

All this is happening again in Brasilia, where I live and the capital of Brazil, very few years after the crisis in São Paulo. Individual water reserves in inadequate containers are increasing, neglecting the fact that the spread of mosquito-borne diseases may rise. I saw some TV shows praising the initiative ...

The measures that Artur listed in a previous message are important initiatives to prevent or mitigate the effects of water crises in cities, and there will certainly be a future opportunity in which they will be better detailed and discussed.

My best regards for all!

Olá a todos, especialmente ao Artur!

A falta de água em cidades por período prolongado é realmente um fato muito desagradável. Lembremos que no Brasil os municípios são responsáveis pelos serviços de saneamento, e questão muito séria é quando governantes locais não conseguem prever e agir adequadamente em momentos de crise hídrica. Logicamente, o ideal é que fossem realizados investimentos em obras que possibilitassem grande segurança no abastecimento público para não se depender da capacidade de reação dos prefeitos. Porém, muitos municípios não contam com recursos suficientes para investimento, o que faz com que o risco de desabastecimento seja muito alto em cidades com crescimento desordenado. Para piorar, grandes perdas ainda são observadas na distribuição da água tratada no Brasil.

Em cidades como Brasília e São Paulo, onde as precipitações médias anuais são superiores a 1.300 mm, as pessoas normalmente não sentiam a necessidade de contar com reservatórios com capacidade muito grande em suas casas ou prédios para acumular a água. A reservação normalmente se resumia ao volume necessário para atender o uso diário. Na crise que ocorreu em São Paulo, a primeira reação dos moradores foi providenciar novos reservatórios para aumentar os volumes acumulados. A população correu para adquirir caixas d’água, que começaram a faltar nas lojas, fazendo com que muitos partissem para a improvisação, utilizando recipientes plásticos ou de metal de baixa capacidade.

O fato descrito mostra que a reação perante as crises tende a ser irracional, não existindo a visão de muitas pessoas de que limitando a reação a esse ato, sem que a água seja economizada, continuará havendo a necessidade de racionamento e os mais prejudicados serão pessoas mais pobres. O pior é que o aprendizado é muito pequeno. Tudo isso está se repetindo em Brasília, cidade em que resido e que é a capital do Brasil, pouquíssimos anos após a crise de São Paulo. Aumenta-se a reservação individual de água em recipientes inadequados, desprezando o fato de que pode ocorrer o agravamento da propagação de doenças transmitidas pelos mosquitos. Vi alguns programas na TV elogiando a iniciativa...

As medidas que o Artur enumerou em mensagem anterior são iniciativas importantes para evitar ou mitigar os efeitos de crises hídricas nas cidades, e certamente haverá oportunidade mais à frente em que serão melhor detalhadas e discutidas.

Meus cumprimentos a todos!

Hello Claudio,

You raise a important point of lack of capacity along with financial unsustainability in operations of local municiplaities. This perpetuates in the form of poor services, lack of planning and dying infrastructure. Where do you think we should have an intervention in this system ? and what role should government and private players have to play ?

I agree Rainwater harvesting is an important step to save water and have water security but  could lead to undresirable impacts if not done right. There is a general momentum in India cities to make rainwater harvesting an important measure. I would like to share the story of city Chennai which In the year 2001 made Rainwater harvesting compulsory for all houses in the city. It helped in terms of groundwater recharge and water security (http://www.tn.gov.in/virtual_directory/dtp/rainwater.htm)

Is a similar policy or initiative taken by any local government in Brazil or mostly its an individual effort ? Do you think RWH can play an important part to make cities water secure and from where and how should the push come from ?

Dear Mohhamad,

In responser to your questions "What do you think are the reasons that countries, specially less developed ones are not able to manage water in urban areas despite these solutions ? Where do you think we should plan our interventions first ?" I want to stress that many of developping countries do not have water supply and sanitation services established based on meeting the key principles. These would include "cost recovery principle", but only aligned with the "operational efficiency principle", where the costs to be recovered need first to be separated by functions and optimized (in terms of NRW management and potential overemployments). Very important to be taken into account is also "affordability principle", actually setting limits to future investments in water supply and sanitation based on the population capacity to pay for those. These three key principles, when all taken into the account, can secure financial self-sustainabilty of the water operators, and only after that other principles like environmental efficiency can also be followed. Water operators that are at the edge of bankrupcy are not able to provide needed level of these services, and too high tariffs (caused by overemployment in utilities, high non-revenue water or other) will cause decrease of payments, what is again serious threat to operations.

Thus the first interventions should be oriented towards building awareness and capacites in developping countries on these principles, as example with establishment of tariff methodology and eventlaully regulatory body too which will ask for tariff requests that clearly shows that they are in line with all mentioned principles.

Any comments to these ideas? 

Corinne Trommsdorff's picture

Corinne Trommsdorff replied:

Dear Branko,

I very much agree with the 3 Principles you list: 1. cost recovery; 2. operational efficiency; and 3.affordability.

To focus on the cost recovery part, I'd like to hear more ideas on the types of business models that could be used considering both public and private approaches. For example:

- tariffs that foster equity

- selecting treatment technologies based on circular economy, where we sell products emerging from waste management.

- Building green infrastructure to improve rainwater management efficiencies, but that also increases the value of properties.  

Can we hear about experiences? what are the lessons learned?

Branko's picture

Branko replied:

Dear Corinne,

Cost recovery principle is closely related to user pays principle, what means that costs of different services (water and waste water) should be clearly separated; the same could be interpreted for different categories of consumers (e.g. legal bodies and private persons/households), but it can hardly be justified that costs of water supply service related to the legal bodies are twice higher than those relating to the households, and that is frequent ratio of the two tariffs in developing countries like mine. Nevertheless that does not mean that households living in upper city zones should have higher tariffs for additional pumping costs.

Regarding any selection of the technology (e.g. treatment as you asked), my opinion is that the first priority or even the constraint for these countries is to follow the affordability principle, what is not always the case with the infrastructure that meets the most efficient or environmental criteria. Gradual improvements are feasible as long as the whole set of operations is financially sustainable, but also the whole system may collapse if focusing primarily to circular economy technologies or green infrastructure if the consequence is raising tariffs to the level that the average population can not pay any more (or even worse, to keep the tariffs that do not include actual investment maintenance costs and thus gradually lead to deterioration of services - and this is often the case in my surrounding, that is the lesson learned).

Hello all, 

Governments and the private sector must pay attention to the urgent need of managing the demand and supply for water, strenghthening the link between water and cities. We can no longer anymore wait until the onset of water crisis, such that Brasilia is facing now and the other that hit Sao Paulo about two/three years ago. From the demand side good examples are the individual collection and payment of water with the use of hydrometers in each house/apartment; bonus and incentives to consumers who are saving water; fines and taxes to consumers who are wasting water or making bad use. From the supply side can be highlighted the investments on green infrasctructures to restore and protect water sources ecossystems; smart engineering solutions for withdrawal, treatment and distribution that are less harmful to the environment and most importantly, the replacement of antiquated and inefficient water distribution systems that leak to much treated water along the networks. The lack of urban (and rural) sanitation to a large extent is also a bottleneck that must be addressed, otherwise it will be ineffective investing in the management of water demand and supply in urban zones.
