Burkli Ziegler Formula – To Determine the Peak Runoff Rate

Burkli Ziegler Formula Burkli Ziegler formula is the oldest formula used to determine the peak runoff rate. It was derived by a swiss engineer for local conditions. After that, it was followed in the whole U.S.A. In M.K.S unites it states that Where, ► = The peak runoff in cumecs. ► = Runoff coefficient (Depending … Continue reading Burkli Ziegler Formula – To Determine the Peak Runoff Rate

Precautions to be Taken While Entering Sewers

Precautions to be Taken While Entering Sewers

Precautions to be Taken While Entering Sewers Various poisonous and explosive gasses are commonly found in sewers such as hydrogen sulphide (H2S), carbon dioxide (CO2) and methane (CH4) along with petrol vapours. These gases are produced largely when the sewage becomes stale and septic, which occurs more commonly in hotter climates. In addition to the … Continue reading Precautions to be Taken While Entering Sewers
