day 1 recycle grey water

Introduction to Water

This PowerPoint Presentation is developed and created by :

Design Brief:

To design a water system that can be used to recycle grey water at Vigyan Ashram.

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?

But first... Lets look at water in general terms...

Introduction to Water Water Supply Sanitation Water Hygiene Waste Management

Why do I need to learn about water?!

Lets find out!

Water Supply

DrinkingCookingWashing

Feeding animalsGrowing crops

What do we need water for?

Water Sanitation

Sanitation...

What is it?

Prevents transmission of

disease

Good hygiene

Removal of Dirty Water

Human waste removal

Why do we need to remove waste water?

Dirtywater

Breeding Grounds for flies

Breeding Grounds for mosquitoes

Contaminates water supplies

Cholera & many more!

Malaria

Soak Pits can be used with latrines

Latrine

Watertight settling

tank

Solids

Liquids

Soakaway

Pre-treatment Required

Septic Tank Soak Pit

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

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?!

Waste Management

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

Design Brief:

To design a water system that can be used to recycle water at Vigyan Ashram.

grey

Water terminology! White Water:

Portable, fresh water than can be used for drinking

Grey Water:Left over water from kitchen sink, bathroom,

showers, hand basins, washing machine etc.

Black Water:Sewage or Wastewater: Any water containing

human waste.

ACTIVITY

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.

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.

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

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.

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?

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.

The end!
