The Underground tanks are used to store water, liquid petroleum, petroleum products and similar liquids. The force analysis of the tanks is about the same irrespective of the chemical nature of the product. All tanks are designed as crack free structures to eliminate any leakage.
This project gives in brief, the theory behind the design of liquid retaining structure i.e. rectangular underground water tank.
This report includes requirement of water tank, survey, excavation methods, Reduced Levels, Average Depth of UGWT, Soil on which it is constructed, Depth of water Table, Type of Mix Design and Capacity of the tank.
Gyanganga society is a residential society being constructed by Goel Ganga Developers formally known as Goel Ganga pvt. Ltd. Ii is being constructed in Rahatani village in PCMC Municipal Corporation.
Society has proposed 5 buildings each of seven floors having 4 flats per floor.
Thus in this project an attempt has been made to design a water tank for storing drinking and utility water to serve daily requirement of the entire society.
The project work consisted of the following –
4. Design Requirments
5. Approval from RCC Consultant
6. PCC and Water Proofing
Water is one of the basic necessarily for a human.An absolute “minimum water requirement” for humans is independent of lifestyle and culture, can be defined only for maintaining human survival.
Different sectors of society use water for different purposes i.e. drinking, cooking food, bathing and washing clothes, sanitation and many other daily use utilities. The water required for each of theseactivities varies with climatic conditions, lifestyle, culture, tradition, diet, technology and wealth.
Water requirements for a society varies upon various factors i.e. No of buildings in society, No of floors in each building, No of flats on each floor etc etc. Moreover if society consists of row houses then water requirement for society increases as per gardening needs. Amenities like common garden, swimming pool, gymnasium, play ground, jogging park and club house have become additional factors of increased water requirement of a society now a days.
Specifications of GyanGanga Society:
1. Total no of Floors = 7
2. No. Of Flats on each floor = 4
3. Total no. of Flat = Total no. of floors * No. of flats on each floor
= 28 flats
4. Average no of person per flat = 6
5. Total no. of personliving in bldg = No of Flat * Avg people per flat
6. Total no. of Buildings in society = 5
7. Total person in society = 168 * 5 = 840
According to Indian Standard,
Consumption of water per person per day (WCPPPD) = 135 ltrs.
WCPPPD includes following division of water requirement:
1. Drinking Water – 4 ltrs
2. Cooking Food – 6 ltrs
3. Dish/ Vassal washing – 25 ltrs
4. Bathing – 25 ltrs
5. Washing Clothes – 20 ltrs
6. Sanitation – 45ltrs
7. Wiping floor – 5 ltrs
8. Watering plants – 5 ltrs
Hence Calculated Total water consumption per day for GyanGanga society
= WCPPPD * Total person
Capacity of the constructed under ground water tank= 1,78,000 LTRS
