Q1/A strip foundation is required to carry a total load of 1556 KN. The water table
locate at 2.35m below the base of foundation. Determine the maximum depth of
foundation that satisfy the bearing capacity equation?. (Use Terzaghi equation)
Note:
Ya =
16 kN/m³
Factor of safety = 3
Width of foundation = 2.65 m
Length of foundation = 1m.
00 = 30
C = 27
Assume the allowable bearing capacity is equal to the actual bearing capacity
(actual).

The city council has proposed building a combined wastewater treatment plant to ensure that domestic and industrial wastewater is treated effectively, meeting regulatory standards for discharge. The community has identified the need for an engineering solution that considers environmental, technical, and operational aspects. Scenario Details: Each person in the city consumes an average of 200 liters of water per day, and the organic load generated per person is 40 grams daily. The city also houses light industries that generate 0.25 million liters per day (MLD) of wastewater with a BOD, concentration of 600 mg/L. Environmental regulations mandate that treated wastewater discharged from the plant must not exceed a BOD5 of 20 mg/L.
