EXPERIMENT 2

The experiment herein involves the collection of water from a dripping faucet. The faucet is set

to drip for 120 minutes and the water collected. In a period of 120 minutes 6 liters of water were

collected. That is to mean, the amount lost per unit time in gallons would be;

Time in minutes

Water Collected

1.5

3.01

4.52

120

6.0

For 120 minutes = 6 liters = 0.264172 X 6 = 1.6 gallons

Water lost per minute = (1 x 1.6)/120 minutes

= 0.0133 gallons per minute

If for every one hour the amount of water lost is 0.8 gallons, then for 24 hours the amount of

water lost will be;

24 x 0.8

= 19.2 gallons

The amount of water lost per year will then be;

19.2 x 365days

= 7008 gallons

According to the American Water Works Association, the cost of tap water is $0.004 per gallon.

Therefore the cost of the drip per year will be;

0.004 x 7008

= $ 28.032

An average shower takes about 8 minutes and the total amount of water used is about 17.2

gallons of water. Then the amount of water in gallons used per minute in a shower will be;

(17.2 x 1)/8

EXPERIMENT 3

= 2.15 gallons per minute

Gallons used per year on shower assuming that one takes a shower once every day.

365 x 17.2

= 6, 278 gallons of water per year.

Cost of water for shower per year = $25.112 per person.

A military shower will take an approximately 3 minutes with the amount of water consumed per

shower being 12 gallons. The amount of water used in taking a regular shower is 17.2 gallons

which is 5.2 gallons higher than the 12 gallons of water used while taking a military shower.

The amount of water saved through a military shower = 5.2 gallons

The amount of water saved per year = 5.2 x 365 days = 1898 gallons

Amount of money saved on water per year = 1898 x 0.004

= $ 7.592

An average faucet has a flow rate of about 1.5 gallons per minute. Assuming that the kitchen

faucet becomes open for 30 minutes every day, and then the amount of water that goes to the

drain from the tap every day would be.

1.5 x 30 = 45 gallons of water.

There are three toilets in our house with each of the three bedrooms having at least one toilet. All

the toilets are regular flow toilets. There are various ways in which a regular flow toilet can be

converted to a low flow toilet. Toilets are the most users of water in every household and an

estimated 4.8 billion gallons of water is flushed in the United States every day. Therefore, it is

important to reduce the amount of water that is flushed by the toilet as a way of saving water and

reducing the amount of water wasted (Wiebe, Gauley Williams & Ziemann, 2015). One of the

ways to convert a regular flush toilet to a low flush toilet is by filling a half gallon container

usually a plastic bottle. Gravel can be added to the bottle ton increase its weight so that it can

sink in the flush tank or the cistern. Then place the container in the cistern carefully lowering it

into the water. Then replace the lid of the cistern. The bottle with interfere with the mechanism

of the flush and hence reduce the amount of water used per flush. The amount of water saved

through this method is significant and can help save money as well.

The amount of water used at home can be reduced by various ways including using sensor taps

to get rid of the cases of running taps. The sensor taps can help in controlling the amount of

water lost through taps that are left running unknowingly (Terlet, Beach & Rezgui, 2016).

Reusing water can also be a good method of conserving water at home. For example, the water

used in the sinks for brushing and the kitchen sink can be reused in flushing the toilet to reduce

the amount of water used in flushing.

New York city has 118,208,250 households. Assuming each household uses 10,000 gallons of

water per month then the total amount of water used in New York is

118,208,250 x 10,000

11,820,825,010,000 gallons of water per month

The main sources of water in New York are from controlled lakes and water reservoirs. The

largest reservoir in New York is the Pepacton with a capacity of about 140 billion gallons. The

main source of pollution to the New York City watershed is the microbial pathogen and

Nitrogen.
