  4. Scheme for left side drainage system

  5. HYDROGRAPH FOR RAIN DURATION 5 minIN LEFT OIL SEPARATOR Q=20 l/s

  6. HYDROGRAPH FOR RAIN DURATION OF 7 min IN THE LEFT OIL SEPARATOR Q=20 l/s

  7. HYDROGRAPH FOR RAIN DURATION OF 10 min IN THE LEFT OIL SEPARATOR Q=20 l/s

  8. VOLUME OF RUNNOF IN OIL SEPARATOR FOR RAINFALL DURATION OF 10 MIN MAX VOLUMEDURATION OF FIRST FLUSH (POLLUTED) OF APPR 6 MIN 0.49 m3/s The first wave of polluted water Retention volume to stop first wave app 80 m3

  9. Longitudinal section of detention pond of80m3, oil separator 20 l/s and by-pass

  10. Plan view of detention pond of 80m3, oil separator 20 l/s and by-pass - left system

  11. Scheme for the right side drainage system

  12. HYDROGRAPH FOR RAIN DURATION OF 7 minIN THE RIGHT SYSTEM OIL SEPARATOR Q=20 l/s

  13. HYDROGRAPH FOR RAIN DURATION OF 10 minIN THE RIGHT SYSTEM OIL SEPARATOR Q=20 l/s

  14. HYDROGRAPH FOR RAIN DURATION OF 5 minIN THE RIGHT SYSTEM OIL SEPARATOR Q=20 l/s

  15. VOLUME OD RUNNOFF VOLUME IN THE RIGHT SYSTEM OIL SEPARATOR FOR RAIN DURATION OF 10 MIN AND 260m3, DURATION OF FIRST FLUSH OF APPR 6 MIN ANDVOLUME OF THE FIRST FLUSH OF 78m3 0.45 m3/s

  16. COMPARATION

  17. CONCLUSION • Proposed solution of the oil separator installation to be just above the ground instead of large excavation and 5 m depth of covering. • Easier approach for oil suction and also silt disposal. • Negligible higher expenses due to energy consumption for pollution water pumping.
