The H2O lovers are back! Today we will be posting tables and charts representing the data collected during the project. We hope that this pictorial representation will help you understand our project better.
The H2O lovers are back yet again! Today we will be posting a comparison between the before and after results together with possible limitations and the reliability of the data collected.
From the data collected, as seen in our previous posts, there was a notable difference between the amount of water used, over a period of five days, before and after the implementation of the water conservation tools. Prior to the implementation of the water conservation tools, 3.5 cubic meters of water was used. However after the water conservation methods were implemented, 3.1 cubic meters of water was used. This is a difference of 0.4 cubic meters. From this data, it would seem that the water conservation methods implemented were a success, as the amount of water used was reduced. However, there are a few limitations that need to be accounted for as they reduce the reliability of the data collected.
The first limitation is that the project was carried out only for five-day periods. To judge the efficacy of the water conservation methods accurately, the project should have been carried out over one-month periods. This would give us more accurate figures as implementing water conservation practices over five days and a month is completely different as it involves a change of habits. Herein lies the second limitation. Over the five-day period, the members in Tanvi's house would have to change their habits. This would not have been easy and as a result the water conservation methods may not have been employed at all times in that duration. Consequently, the data obtained would be inaccurate.
While our project did yield us positive results, we hoped that an understanding of the project limitations would allows us to have a more practical and objective view towards the practice of water conservation in the household.
For now, this is all. See you soon!

The H2O lovers are back again! Today, we will be posting the complete water data readings prior to the implementation of the water conservation tools, and the initial water meter reading as we introduce the water conservation methods.
Below posted are the water meter data readings for the 1st, 2nd, 3rd and 4th day, prior to the implementation of the water conservation tools and the amount of water consumed each day.
1st Day (6th June 2011, 1400 hrs)
Reading: 5073.9 cubic meters (m3)
Amount of water used: 0.5m3
2nd Day (7th June 2011, 1400 hrs)
Reading: 5074.8 cubic meters (m3)
Amount of water used: 0.9m3
3rd Day (8th June 2011, 1400 hrs)
Reading: 5075.4 cubic meters (m3)
Amount of water used: 0.6m3
4th Day (9th June 2011, 1400 hrs)
Reading: 5076.1 cubic meters (m3)
Amount of water used: 0.7m3
On the fifth day, Friday, 10th June 2011, 1400 hours, we took the water meter readings again to obtain the complete data for the amount of water consumed, over five days, before the implementation of water conservation methods. The reading is shown in the picture below.
From the picture, the water meter reading is 5076.9 cubic meters (m3).
Amount of water used: 0.8m3 Initial Reading: 5073.4 cubic meters Final Reading: 5076.9 cubic meters Amount of water consumed: 3.5 cubic meters
Our aim is to use a smaller amount of water, than stated above, upon the implementation of water conservation methods.
Water conservation methods were implemented from Saturday, 11th June 2011, 1330 hours in Tanvi's home. The initial reading is as follows:
From the picture, the water meter reading is 5078.3 cubic meters (m3).
The water conservation tools will remain in place till Thursday, 16th June, 1330 hours. Then the water meter reading will be taken again and we will be able to see the impact of our water conservation efforts.
For now, this is all. See you next week!

Next Post: Final water meter readings after implementation of water conservation methods and videos and photos of the implementation
The H2O lovers are back! Today, we will be posting information related to the collection of water data and some of our water meter readings, prior to the implementation of the water conservation tools.
During our research, we came across the SP services website which provided instructions on how to read the water meter. This was especially helpful, as no one in the group had an idea how to read the water meter accurately. The information found is as follows,
" THE WATER METER
The water meter measures the amount of water in cubic meters. Read only the first five numbers from the left. You will notice that these are the first four numbers in black and the fifth number in red on your meter. " http://services.spservices.sg/
Using this information, we collected water readings from the water meter at Tanvi's house. The reading is dated Sunday, 5th June 2011, 1400 hours.
From the picture, the water meter reading is 5073.4 cubic metres (m3).
We decided to measure the water consumption in Tanvi's house over a period of five days (i.e. till Friday, 10th June 2011, 1400 hours) prior to the implementation of the water conservation methods. These readings would then allow us, in future, a clear comparison in the amount of water consumed with and without the water conservation tools in place. This will also enable us to judge the efficacy of the water conservation tools chosen as mentioned in the previous post.
That's all for now!

Next Post: Complete data for water usage prior to the implementation of water tools.
This is Tanvi, Daryll, Keith, Benjamin and Jeremy here and we are called the H2O Lovers. In today's post, we will be telling you about the water conservation habits (for households) we plan to implement as part of our project.
After much debate and discussion, we have decided on the following water conservation methods. The reasons for our choices shall be explained further. The water saving habits chosen are as follows:
1) Washing vegetables, fruits and kitchen utensils in a filled sink, instead of under running water.
2) Operating the washing machine on a full load.
3) Using the half-flush cistern in toilets for liquid waste.
4) Keeping the tap in wash basins turned off except when in use. (e.g. Turning the tap off while brushing teeth and/or using a tumbler to rinse mouths)
5) Re-using water (e.g. Leftover water from washing vegetables can be re-used to water plants)
We have chosen these activities based on the Public Utilities Board's (PUB) data on the water consumption patterns of a typical Singaporean household.
Below is the pie-chart on PUB's website showing the percentage breakdown of water use for each activity in a typical household.
From the pie-chart it is evident that showers and washing in the kitchen sink takes up 29% and 22% of an average family's monthly water consumption respectively. Hence our water conservation efforts should be largely focused on these areas.
Despite showers taking up the largest proportion of water consumption per household, we have chosen not to implement any water saving methods with reference to this activity, owing to difficulties in recording evidence of the implementation of water conservation methods for this activity. Consequently, we have chosen to implement water saving habits in every other household activity as stated in the pie-chart above.
In the table below, each of the water saving habits we plan to implement has been grouped under the categories described in PUB's data.
Water Conservation Method
Category
Washing vegetables, fruits & kitchen utensils in a filled sink instead of under running water
Kitchen Sink
Operating the washing machine on a full load
Laundry
Using the half-flush cistern in toilets for liquid waste
Flush Cistern
Keeping the tap of the wash basin turned off except when in use
Wash Basin
Re-using water
Others
We hope that these efforts will be successful in conserving water as water is a precious resource, especially in a country like Singapore which lacks its own water resources.

H2O Lovers
