To do this we must answer the ‘What,Who,Why,When,How’ questions;What is the project?Who is the project for?Why are we making the project?When does the project have to be
finished by?How are we going to do the project?

Water Sanitation
![Page 9: Day 1 recycle grey water](https://reader038.vdocuments.site/reader038/viewer/2022110121/5589e72ed8b42aa50c8b46cd/html5/thumbnails/9.jpg)
Sanitation...
What is it?
Prevents transmission of
disease
Good hygiene
Removal of Dirty Water
Human waste removal
![Page 10: Day 1 recycle grey water](https://reader038.vdocuments.site/reader038/viewer/2022110121/5589e72ed8b42aa50c8b46cd/html5/thumbnails/10.jpg)
Why do we need to remove waste water?
Dirtywater
Breeding Grounds for flies
Breeding Grounds for mosquitoes
Contaminates water supplies
Cholera & many more!
Malaria

Septic TanksThe tank needs periodic cleaning to remove scum and built up sludge about every 3 years.
Waste water needs to remain in tank for minimum 24 hrs to ensure it settles

Water Hygiene
![Page 14: Day 1 recycle grey water](https://reader038.vdocuments.site/reader038/viewer/2022110121/5589e72ed8b42aa50c8b46cd/html5/thumbnails/14.jpg)
Water Hygiene
Why?Good water hygiene can improve
health and wellbeing What?
Scrubbing your hand with soap for more than 20s can reduce risk of illness by up to 90%.
Does anyone know the correct hand washing method?!
![Page 15: Day 1 recycle grey water](https://reader038.vdocuments.site/reader038/viewer/2022110121/5589e72ed8b42aa50c8b46cd/html5/thumbnails/15.jpg)
Waste Management
![Page 16: Day 1 recycle grey water](https://reader038.vdocuments.site/reader038/viewer/2022110121/5589e72ed8b42aa50c8b46cd/html5/thumbnails/16.jpg)
Why is waste management important?
Protects human healthReduce environment pollution
Make rural areas clean
Convert bio waste into energy
Improves quality of life
Promotes recycling and reuse-save resources

Split into 4 groups
Decide on a team name Choose a team leader

Survey
Survey how water is used in Vigyan Ashram
Use a range of tools to survey:Photographs & videosDraw mapsSketches
Be thorough – we want to have all the information about water supply and wastewater at Vigyan Ashram.
![Page 22: Day 1 recycle grey water](https://reader038.vdocuments.site/reader038/viewer/2022110121/5589e72ed8b42aa50c8b46cd/html5/thumbnails/22.jpg)
Photographs
Think about the photograph you are taking:Describe what is happening in the
picture? Why? If someone else who had never been
to Vigyan Ashram looked at photos – what would they see?
The camera can be borrowed for today but must be returned by 5pm.
![Page 23: Day 1 recycle grey water](https://reader038.vdocuments.site/reader038/viewer/2022110121/5589e72ed8b42aa50c8b46cd/html5/thumbnails/23.jpg)
Draw maps Water moves, map where it comes
from and where it goes. Draw a plan of the whole ashram in
your sketchbooks. Map water usage. E.g:
Cow shed
Office/Kitchen
WorkshopEnergy & Environment
EngineeringGuest house
ClassroomBoys’s Accommodation
Water Pump
Ama’s
Anan’s
Foodlab

Storage
Take a measuring tape with you and note measurements of tanks.
Also use measuring tape to work out how long pipes are between storage and usage.
Take particularly detailed measurements around kitchen sinks and water storage for kitchen.
![Page 25: Day 1 recycle grey water](https://reader038.vdocuments.site/reader038/viewer/2022110121/5589e72ed8b42aa50c8b46cd/html5/thumbnails/25.jpg)
Answer the following questions:
Where do we get our drinking water?
Where is it stored? Where does the wastewater from
all the toilets go? Where does the water from the
sinks and bathrooms go? Where would be good to use grey
water recycling?
![Page 26: Day 1 recycle grey water](https://reader038.vdocuments.site/reader038/viewer/2022110121/5589e72ed8b42aa50c8b46cd/html5/thumbnails/26.jpg)
But first plan how you are going to conduct the survey as a group...

Homework
By tomorrow:Complete group water assessmentAlso... write down the stakeholders
involved in this project and their needs....
If you would like assistance I will be in office.
