WATER CALCULATIONS FOR ABUJA HOUSE WATER SUPPLY Step 1: Number of Persons 1 House x 5 Bedrooms/House = 5 Bedrooms Step 2: From Fig. W-4(Planning Guide for Water Supply) 50-75 Gallons/Perosn/Day is required since it is a single family resident 10 Persons x 75Gallons/Person/Day = 750 Gallons/Day Step 3: Assuming a pumping period of 20 Hours (4 Hours resting period for pump): 750Gallons/Day / 20 Hours/Day = 37.5 Gallons/Hour Step 4: Since water obtained from wells and the rating of the pump used are based on gallons per minute. Therefoe, 37.5Gallons/Hour / 60minutes/hour = 0.625 Gallons/minute Step 5: We need a well to produce 2 to 3 gallons per minute DESIGN OF WELLS Step 1: 1H x 5 B.R/H = 5 B.R 5 B.R X 2 P/B.R = 10 P Step 2: 10P X 75 G/P/D = 750 G/d Step 3: Assume pumping period 20 Hours/d 750 G/d / 20h/d = 37.5 G/h Step 4: 37.5 G/h / 60m/h = 0.625 G/M Step 5: It is a good practice to design a pneumatic tank to supply water for 6 hours 6H x 37.5G/H = 225G rounded to 250G A 250G pneumatic tank is required.

16


WATER CALCULATIONS FOR ABUJA HOUSE COLD WATER DISTRIBUTION - UPFEED DISTRIBUTION SYSTEM Step 1: Using a flush valve. Pressure required is 10 to 20psi, so an average of 15psi would be used. Cold water has a pressure of 60psi. 1psi = 2.3ft/psi Therefore, 60psi - 15psi = 45psi

45psi x 2.3ft/psi = 103.5 ft

103.5ft / 15ft/stories = 6.9 stories = 7 stories

Step 2: using a flush. Flush tank require 8psi Therefore, 60psi - 8psi = 52psi

52psi x 2.3ft/psi = 119.6 ft

119.6 ft / 15ft/stories = 7.97 stories = 8 stories

HOT WATER DEMAND In this private home, the hot water consumption would be as follows: Tub bathing

25 gallons

Showering

6g/m

Washing machine 36gallons/wash Dishwashing

10gallons/wash

17


WATER CALCULATIONS FOR ABUJA HOUSE WATER HEATER FOR HOUSE Since it is a 5 Bedroom with 4 1/2 bathroom house, the 1-hour draw for a Gas heater is about 92 Gallons/hour (Figure W-20) A 92 Gallon/h water heater would be required for the house. COST OF PRODUCING HOT WATER Energy = Btu/month / energy value x efficiency = gallons, therm, or kWh Heating with natural gas Step 1: 10P x 75G/D = 750G/P/D 30 days in a month 750G/P/D x 30D/M = 22,500G/M Step 2: Total BTU = G of water x 8.33lb/G x 1Btu/deg x Change in temperature Total BTU = 22,500 G/M x 8.33 x 1 x (120 - 50) = 13,119,750 Btu/M Step 3: Energy = BTU/M / Energy Value x Efficiency The house would use natural gas, = 13,119,750BTU/M / 100,000Btu/therm x 0.8 = $164 cost using natural gas/month

CALCULATIONS FOR THE LEECHING FIELD DESIGN OF A LEECHING FIELD Step 1: Using Fig. S-3 for the house sewage flow, it is 75 gallons per person per day. 75G/p/d x 10p = 750 G/d size of septic tank Step 2: Using Fig. S-8 for 10 minutes drop of 1-inch and trench width of 3 feet, 20 feet of length is required per 100 gallons per day 750G/d / 100G/d = 7.5 7.5 x 20 feet = 150 feet of tile field Step 3: It requires 6 lengths of tile drains 25 feet long with a trench 3 feet wide.

SEEPAGE POOL/LEECHING POOLS Step 1: House sewage flos is 75 gallons per person per day 75G/p/d x 10p = 750 G/d Step 2: The effective absorption area in seepage pits for eacn 200 gallons of sewage per day for 10 minutes for 1-inch drop is 75 sf.ft 750 G/d / 100G/d = 7.5 7.5 x 75 sq.ft = 562.5 sq.ft Step 3: Using Seepage pits/leeching pools with an 8-ft diameter and a 6-ft depth has an absorption area of 150.7sq.ft 562.5 sq.ft / 150.7 sq.ft = 3.73 units = 4 units The house can use 2 seepage pits 8 feet in height (two units/seepage pits) Step 4: Spacing of seepage pits outside to outside 10 ft or 1-1/2 times effective depth. 1.5 x 8 feet = 12ft The seepage pool will use 12 feet spacing

CALCULATIONS FOR FLAT ROOF DESIGN OF STORM DRAINAGE FOR FLAT ROOF Step 1: The maximum hourly rainfall for Abuja Federal Capital Territory is greater than 6in/hr. Step 2: The roof area totals about 40ft by 70ft + 23ft by 60ft + 40ft by 15ft = 2800sq.ft + 1380sq.ft + 600sq.ft = 40ft x 23.3ft + 23ft x 20ft + 13.3ft x 15ft = 4780sq.ft/ 3 = 1593.3sq.ft/section Step 3: The roof area of each section should be sloped in order to direct the rainfall toward the roof drain by using lightweight concrete or sphalt Step 4: The horizontal rainfall piping size from Fig. D-8 using 6in/hr rainfall 1/8 in. slope and 1593.33sq.ft area.

PIPE SIZE is 5IN and is good for 2227sq.ft area.

For the horizontal pipe 20ft x 1/8in/ft = 2.5 in., which is OK 23.3ft x 1/8in/ft = 2.99 in., which is OK 13.3ft x 1/8in/ft = 1.66 in., which is OK

Step 5: Leader Size 4,780 sq.ft area of roof , Using D - 6 for 6-in/hr rainfall, size of leader is 5 in., good for 5,765sq. ft.

Leader size is 5-in.

Step 6: No balconies Step 7: No balconies Step 8: Size of horizontal storm drain. From Fig. D-8, using 1/8in. slope, 6in/hr rainfall: 5-in. storm drain, 1/8 in. slope

RESEARCH: RAINWATER HARVESTING

Old Practice - mainly used for agricultural purposes Rice Terraces in Philippine have been using rainwater for 1000s of years now Rain water systems have been in use in India since 3000 BC Gutters were used to fill jars & pots in Thailand & Southeast Asia, over 2000 years ago The earth dams of ancient Egypt were used to control runoff. Ancient rain water cisterns can still be seen on the islands of Capri and Malta. An underground cistern collected rainwater. The Romans - developed underground cisterns & used their systems as air conditioners. The Roman’s shallow pool mirrors the modern day roof washer or first flush system The world’s largest Cistern was built by Caesar Justinian in 527 AD Yerebatan Sarayi, Turkey. It can store 80,000 cubed meters of water Binbirdik is another cistern in Istanbul, Turkey by Caesar Constantine in 389 AD New Rainwater Harvesting Technology used in Loess Plateaus of China, 1970’s The technology disappeared due to increasing urbanization (Industrial Age) However, due to modern day water pollution and drought,rainwater harvesting techniques have come back into practice again. Rainwater Harvesting is the accumulating and storing of rainwater for reuse before it reaches the aquifer. It has been used to provide drinking water, water for livestock, water for irrigation, as well as other typical uses. Rainwater collected from the roofs of houses and local institutions can make an important contribution to the availability of drinking water.

Place solar panels on the roof top to produce energy for the house from the sun. Having a more exposed roof surface has allowed it to be possible for more of the sun’s rays to be used in such a hot climate. However, even though the sun would provide energy for the house, it might make it too hot as this climate tends to be humid!

GREEN ROOF

There is a lot of rainfall in Abuja, Nigeria. The raining season occurs for about 7 months and considering the fact that there is water scarcity at times in the country, it makes sense to cater to the needs of those living in the country by using rain water harvesting. Also, the water can be used to take care of the roof top garden during the dry season. Using an underground cistern could help in storing the water needed for the house. WIND WHEEL

Allow basement floor roof and first floor roof to be accesible so that the building can benefit from the cool temperature and the clean air brought about by the green roof. Allow plant for food could be planted to create a roof garden for the house.

wind mill turbines on roof

The house is located in a mountainious region so to the high altitudes could be used to help cool the building using personal wind mill turbine on the roof of the house. This could be placed on the roof of the top most floor. Also, this could be another source of energy for the house.
