Gender equality! Vivid, right?

Here we have two men imposing violence on women and a woman struggle to climb over the obstacle of discrimination.

Education and legislation are effective means to guarantee woman rights.

Finance is highly related to SDGs.

 

Impact investing targets both financial and social return.

Crowdfunding requires public knowledge and support for ideas to promote SDGs.

Due to the rapid population growth and agricultural development, the course of industrialization and urbanization, water quality in the Lower Mekong Delta is degrading.

Eutrophication and salinization associated with human activities and meteorological factors may be the most predominant problems of the deteriorating water quality.

This forces swift adoption of a rapid, reliable and cost-effective way of measuring water quality indicators locally and then effective solutions to improve water quality.

Monitoring is the prerequisite of improving. Also in accordance with what UNICEF in Vietnam is doing, we would like to develop innovations in this area.

“Water quality” is a term used here to express the suitability of water to sustain various uses or processes. 

The principal reason for monitoring water quality has been, traditionally, the need to verify whether the observed water quality is suitable for intended uses. However, monitoring has also evolved to determine trends in the quality of the aquatic environment and how the environment is affected by the release of contaminants, by other human activities, and/or by waste treatment operations.

 Monitoring for background quality of the aquatic environment is also widely carried out, as it provides a means of comparing and assessing the results of impact monitoring.

Water quality can be described by a single variable or by any combination of more than 100 variables. For most purposes, however, water quality can be adequately described by fewer than 20 physical, chemical and biological characteristics.

The simplest combination of variables is temperature, electrical conductivity, pH, dissolved oxygen (DO) and total suspended solids (TSS). These give the bare minimum of information on which a crude assessment of overall water quality can be based.

Have you considered adding water and air temperature sensors?
over 1 year ago
Hello pingu_98,
The water temperature sensor is included in the Electrical Conductivity Sensor that you can find here as well.
We haven't considered measuring the air temperature, do you think it will be useful?

The Riffle is a collection of designs that take an open source approach to water monitoring, with the intent of making gathering water information easier and more accessible.

The Coqui: using audio as a sensor data format. We're also exploring using audio frequencies to convey sensor readings -- like a modem, but even simpler -- in order to make sensor readings more accessible for people (or to enable data transmission over ubiquitous audio jacks on PCs and smartphones). Read more about this idea on the Coqui wiki, or look for recent updates on Public Lab here.

A mailing list. Sign up for the plots-water-quality email list, and participate in discussions about low-cost, open source water quality monitoring tools and techniques.

The Apparel and Footwear Sector and Children in Vietnam

(Information from a qualitative research undertaken in 2016 in Ho Chi Minh City, Vietnam )

Although most workers have access to improved water sources, migrant workers are most likely to lack access. As a result, many migrant communities rely on well water which is not suitable for drinking.

Improved sanitation can reduce diarrheal diseases by more than a third, and can lessen the adverse health impacts of other illnesses. Many workers have access to flush toilets in the home, and open defecation rates are low across Vietnam. However, migrant workers are more likely to lack adequate sanitation facilities.

Workers living in and around industrial areas may be affected by pollution and polluted water sources. Not all industrial parks are equipped with up-to-date water treatment facilities. The impact could therefore worsen in the near future, due to increased investment in lower tiers of the supply chain.

WASH in the workplace

There are also WASH challenges in the. According to a survey of 8,000 workers at a footwear factory in HCMC, less than half of workers reported regularly washing their hands after using the toilet. Poor handwashing practices are the result of both lack of awareness among workers, and limited access to soap and handwashing taps at work. Furthermore, not all factories have a sufficient number of toilets, or have the same number of toilets for males and females despite the latter comprising 80% of the workforce. Even for those factories with a sufficient number of toilets, toilet breaks are often limited due to the pressure of reaching daily production targets.

On our first day in Vietnam (3/8/2017) we visited the office of Unicef in Ho Chi Minh city. There, by the hand of Mr Brian Desmond Cotter we learnt about the big and complex problems that the country is facing right now, concerning water and inequities among children.

As well we had a skype call with Mr Lalit Patra, Chief of UNICEF Viet Nam’s Water and Sanitation team, who presented us the challenges of Vietnam concerning SDG6.

During our visit to the Mekong Delta we detected many water and enviromental issues that are affecting the region. Here are some pictures and comments from our visit.

- The brown color of the river describes the huge amount of suspended matter that is present in the Mekong river.

- According to our guide, the eutrophication problem caused by the free use of fertilizers in the region can be visually detected habitually by the change of the river water color (from brown to green).

- Tap water is not drinkable without boiling.

- Free waste disposal affects the basin of the river

- There is an increasingly aquaculture industry in the basin of the river that provoques not only visual changes in the enviroment but generates odours

- Water sanitation is not very accessible, even at the touristic places.

During our stay in Ho Chi Minh City we visited Fab Lab Saigon, the first maker space in the city.

In Fablab we had access to all of the materials that are available at their place and we received help from the experts who work there.

Thanks to them we have our temperature sensor finally working and we tried to callibrate the EC - Sensor but we found that the solution to callibrate it had been damaged for some reason, maybe because of the conditions of the solution in the transportation from Geneva to Ho Chi Minh City.

As well we used the 3D printer to create a Folding Box for Arduino Uno and the BreadBoard. We got the design from thingiverse. Find here the design acknowledgements: https://www.thingiverse.com/thing:527543/attribution_card

Please find the details about the space and materials here:    https://fablabsaigon.org/

The 4th August 2017, we visit to the Saigon Clean Water Business and Investment Joint Stock Company (SWIC).

Saigon Clean Water Business and Investment Joint Stock Company (SWIC) is the first producer of clean water in Ho Chi Minh City. Since November 2010 People’s Committee of Ho Chi Minh implemented the Project “Expansion of Thu Duc Water Plant phase III, Capacity 300’000m3/ day”.

Saigon Water Corporation (SWACO), the main shareholder of SWIC, holds 60% and is composed by eight companies in charge of delivering water to Ho Chi Minh households. Refrigeration Electrical Engineering Corporation (REE) holds 30 % of SWIC and the 10% left are holed by Vinh Thinh Corporation. 

For a total invest of 1.200 billion VND (52 800 U.S. dollars) the construction began in April 2013; Plant inauguration took place in August 2015 and the water supply has been operational since December 2015. The funds were provided by the Vietnamese Bank and the German Bank. 

To treat the water from Dong Nai River, German equipment like Chemical stations were distributed by Passavant Roediger, henceforth call Passavant Energy and Environment

SWIC checks the water quality at the begging of the chain 2-3 times per week; after the filter process, turbidity is constantly checked. A French company tests 109 indicators once per month. After this treatment, the quality of water is checked by the eight delivery companies (SAWACO) of the city. 

However, Ho Chi Minh City’s tap water does not rich the WHO drinking water standards.

The first thing that we have done in China, ( Tsinguha University, Beijing,) is to put all codes related to ours four principales parameters together. The value of pH, Temperature, electro-conductivity and turbidity can be visualize on all together in real time by running the following code.

In Beijing we also equip the device with a Bluetooth module that will permit us to develop the android application that will support our hardware.

Please find the information related to the app on https://github.com/dadaduoduo/WaterQuality
