Sewer Construction: What Are Your Options When It comes to Shape?Terohan Nula April 19, 2018 0 COMMENTS
A sewer system is an essential part of all municipalities. Its construction should be handled diligently to avoid overflows and keep your town clean regardless of the circumstance. One of the considerations that play a significant role in the working of your sewer system is its shape.
The shape of your sewer affects its cost, maintenance, and design. A civil engineering firm in New Orleans will assess your topography, amount of waste and other factors and advise you on the ideal shape for your system. Here are some of the sewer shapes the engineers might recommend.
A circular sewer is the most common one. A circular sewer is easy to construct and has a smooth inner surface, allowing for uniform sewage flow and hence minimizing the chances of suspended particle deposition.
The nominal size of a circular sewer is denoted as DN corresponding to its internal diameter. A circular sewer is, however, costly to construct.
Egg-shaped sewers are typically used for combined sewer systems. Ovoid sewers are used in an upside-down configuration to lower their water level line, make them easily accessible and to improve their static effects.
These sewers have a reduced waste emission in wet climatic conditions and better handling of large waste quantities and self-cleansing velocity in dry weather. Egg-shaped sewers are however less stable compared with circular shaped ones.
This sewer has a semi-circular shaped top with vertical or inclined sides. Horseshoe-shaped sewers resemble a tunnel with their height less than their width doing maintenance works in these sewers easy. Horseshoe-shaped sewers are typically constructed in places with heavy sewer discharge.
Sometimes civil engineers might recommend the use of different shapes for different sections of your sewer system. This improves the efficiency of your sewer system. Getting an experienced and well-qualified civil engineer for your project is essential to getting a perfect sewer for your town.
