If you are the mayor of a town or a city, there is a good chance that the last thing that you want to happen is for your city to experience flooding. This can disrupt traffic and make everything take longer. It can result in permanent, expensive property damage. It can also make cause the citizens of your city to feel concerned and unsafe. Here are some municipal engineering tips that you can follow to in order to reduce the chances that a flood will occur.
1. Check Sewer Capacity
The first thing that you should do is hire a municipal engineer to check the capacity of your sewers. This is important because if too much rain should fall, your sewers will get backed up and cause flooding. Your sewer system is going to be the first line of defense against flooding because it will carry the water away to a less dangerous location. You can check the capacity of your sewers by stress testing a select number of areas in the system and increasing the amount of water that they are carrying. If they are overflowing in your tests, then they are going to overflow should a heavy rain hit. You will need to expand your sewer system in order to allow it the additional capacity to cope with more water.
2. Increase Efficiency of Water Removal
The next thing that you will want to look at is the overall efficiency of water removal from the streets and sidewalks to areas where it is not going to impede normal or pedestrian traffic. This will allow you to prevent areas that commonly have standing water from doing damage to the foundations of buildings. It will also allow you to prevent cosmetic damage after a heavy rainfall. You will want to look into systems that you can build that automatically carry water down hills and then increase the carrying capacity for sewers at the bottom of said hills. You might also want to build additional entries into the sewer system in order to make sure that it adheres to floodplain mapping and will allow the water to be taken from the streets as quickly as possible.
For more information, talk to a municipal engineer. He or she will be able to pinpoint the locations of your city that are going to be most vulnerable to flooding, which will allow you to spend your tax dollars wisely.
