Hospital Water Demand/Consumption: A Case Study of Ahmadu Bello University Teaching Hospital, Shika.

This work provki/r^sis of understanding groundwater potential of the Ahmadu Beljp .‘,|:r»iversity - ^ j ting Hospital, Shika, the water demand and requirement for \ The resistivity values obtain shows the water bearing zones ranges fmone point 4v ree other. The water potential of the area is good though, the ,e varies uom point to point depending on the conductivity, thickness, and ■Ti-TTer characteristics. Shika hospital is located on Metamorphic (Gneiss) with maximum thickness of water bearing soft rock of 30 m. The two interconnected aquifers, the Soft Overburden and the Fractured Crystalline Aquifers stores good quantity of water. The groundwater flow directions of this area which stores water is that the water flow away to recharge the surface water. Solution to water problem in the study area is to rely on surface water via overhead tanks and the use of groundwater for emergency situation. Water demand of the Hospital is 154 m3/d. Total water demand of the hospital is 438.39(m3/d) and Unit water per day per bed is 0.877(m3/d). The Hospital Static Groundwater Resources 494,350m3, Total Dynamic Groundwater Resources 58,518.1m3/a and Utilizable Dynamic Groundwater Resources 29,259.05m3/a or (80.16 m3/d). The water demand /requirement using WHO (2005) standard is 77,000 Ipcd (77m3/d). The unit water demand per bed per day of Shika hospital is 0.877 m3/d. The coefficient of surface runoff of the study area is 0.18, base flow (infiltration) 0.1, and total runoff 0.28. The annual volume of surface runoff for ABU Teaching Hospital Shika is 1,039,209 m3/a. Total surface water resources of the study area is 1,918,636 m3/a. Proper planning is fundamental to protection, conservation and constant water supply. ABUTH water supply has been from boreholes, Zaria and Ahmadu Bello University (ABU) water works. Therefore, with proper management, ABUTH should not experience water scarcity. All the storage tanks both ground and overhead should be reactivated and sluice valves replaced and/or serviced with good chamber for proper security to minimize usage, wastage and delivery of water to different department of the hospital through its water distribution network pipeline while its groundwater resources should be a supplementary water sources because a hospital should have constant water supply and ABUTH should not be an exception.
