1. DIGHWARA
Water demand calculation of Dighwara Dhobi ghat
Wastewater generation from the proposed facility
Design Capacityofthe ETP wouldbe 1.5 times the wastewater discharge:
1.5 x 9720 = 14,580 litres
= 0.014 MLD
= 0.01 MLD
1 Total number of identified dhobis in Dighwara 6
2 Average number of clothes washed per day in Dighwara (as per survey) 300
3 Average number of clothes washed per day per dhobi in Dighwara 50
4 No. of washing units proposed in one dhobighat 6
5 Average water requirement for washing of 1 cloth 15 litres
Total water demand for 12 dhobis in proposed dhobighat 12 x 50 x 15
= 9000 litres
S. No. Water use and Wastewater discharge Litres
1 Average estimated water use in washing/day @15liter per clothe 9000
2 Leakageand wastageof water @ 20% 1800
3 Other usage of water including of W/C, Bathing @ 15 % 1350
4 Total Water demand for proposed Dhobighat (water use/day) 12150
5 Total Wastewater discharge in proposed dhobighat@80% 9720
