What size septic tank will you recommend for a 2-bedroom house? If the AR for the house is determined to be 0.4 gal/ft2 /day, what size drainfield should be designed? Show the layout for the drainfield if the trench width is 5 feet and the maximum length is 100 ft. Space the laterals 6 feet from each other on the center. How does your layout change if the drainfield area is determined from the figure based on a perc rate of 30 minutes/inch?

Question 3 The horizontal layout of foul sewer network is shown in Figure Question 3. The sewer network comprised of four sewers starting from MH1 to MH4. Manhole ground elevations are shown in Figure Q 3 (a). All sections are of equal length. The total length of the sewers is 273 m. a) Calculate the invert elevations for the sewers from MH1 to MH4 using minimum cover for the sewer as 2.0 m and pipe wall thickness as 50 mm. b) Using suitable scale plot the sewer profile and shown necessary data required.
