Water Distribution & Wastewater Collection Systems
Wastewater Treatment & Sewage Lines
Wastewater collection systems are as crucial as water distribution systems. If proper capacity and maintenance are inadequate it can lead to severe environmental impact and sanitary issues. Improper wastewater collection systems will result in an overspill that may flood the streets with contaminated and polluted water. This water can carry and spread diseases. Further, it can also accelerate the production of hydrogen sulphide, which corrodes the systems.

What is Wastewater Collection System?
Distribution of fresh portable water usually has the first priority. However, getting rid of the wastewater is just as important. Failure to do so can lead to contamination and pollution of various water resources in turn hampering water distribution.
Wastewater collection systems are responsible for gathering used water from houses, commercial buildings and industries. It then conveys this water to wastewater treatment plants. This type of system is also called a sanitary sewer. A similar system known as a storm water collection system conveys water resulting from runoff of rain and snow. It collects this water from buildings, paved and unpaved areas and releases it into natural water resources, usually without treatment. This type of system is also known as a storm sewer.
Until a few years ago, sanitary sewers and storm sewers were usually combined into one system. However, during heavy rains the wastewater treatment plant served by these combined sewers would often become hydraulically overloaded. This would lead to a washout into the receiving water resources causing a complete wastewater treatment system failure. Due to this reason combined sewers are now quite rare.
Types of Wastewater Collection Systems
Wastewater collection system helps in effective collection of wastewater generated from various domestic and industrial activities. Any structure with running water, like a residence or office, is most definitely connected to some sort of wastewater collection system. In other words a wastewater collection system includes everything except the wastewater treatment plant. This includes every line, lifts station, pumps stations, manholes, and conveys sewage to the treatment plant. There are usually two types of systems and they are stated as follows:
- Centralized Wastewater Collection Systems:
Centralized systems are large-scale public sewer systems like municipal wastewater treatment plants. They generally serve established cities and towns and sometimes provide treatment and disposal services for neighboring sewer districts. Usually centralized systems are preferred over decentralized systems. This is because it turns out to be economical and cost effective, allows greater control and monitoring and requires fewer people for operations.
- Decentralized Wastewater Treatment Systems:
Decentralized septic systems are used for wastewater treatment and disposal by homes and other buildings that is not connected to the public sewer systems. Most decentralized systems are on-site systems where wastewater is treated underground from where it is generated. On-site Wastewater treatment system is commonly used in rural areas. These systems can either be as small as a single septic system and drain field serving one residence or as big as a large soil absorption system serving an entire subdivision.
A private wastewater treatment plant is used to treat wastewater in decentralized systems. These plants have similar treatment process and equipments as centralized systems, however on a smaller scale.
However, these two types of wastewater collection systems are further classified as under:
All wastewater that is generated by people from residential, commercial and industrial uses are carried by this system to the wastewater treatment plant. Here it is treated before being discharged in water resources.
Only rain and snow water is carried by these systems. It includes catch basins on the side of the roads where the water is collected and conveyed to a discharge point usually a water resource. These systems do not include a treatment before being discharged.
This collection system is a combination of sanitary and storm system. These systems are being phased out but still can be found in some old cities. Wastewater that is collected in this system is treated first before being discharged in water resources.
Types of Sewage Lines in a Wastewater Treatment Collection
A wastewater collection system includes everything except the wastewater treatment plant. This includes:
Any line that conveys sanitary wastewater from lateral lines to the wastewater treatment plant is called sewer mains. There are two types of sewer mains namely force and gravity.
A force main is one that is pumped under pressure usually for carrying sewage uphill. The wastewater is pumped to a higher level generally from a lift station. Typically, force mains are relatively short. However, in a terrain that is hilly, or large systems, they can be five or more miles long. Rarely any grease problems are found in force mains. This is because the force of the water running through clears away grease from the mains. However, the problem usually faced is odor. This again is controlled through administration of proper odor control systems.
Gravity main as the name implies runs downhill. These are the most commonly used mains. They also make up the greatest percentage of wastewater collection systems. However, most of the grease problems are encountered in gravity mains.
Lines that carry wastewater to a larger pipe are called lateral lines. For instance, the line in a kitchen sink is approximately two inches in diameter. It runs to a four-inch line that runs to the street. That four-inch line is the house main when in the building. However, it also becomes a house lateral when it runs out to the streets and connects to a larger line owned by the municipality. These municipal sewers are often referred to as 'the city'.
A location in the wastewater collection system where two or more lines meet and enter a large pipe is called interceptor. These come in numerous sizes and are usually manholes or large chamber.
A pit inside a building that serves the same purpose as a lift station is called an ejector pit. It is used to lift water to a higher level. Wastewater from the building flows into the pit where it is pumped out to the city main.
Based on the information provided above, we can conclude that wastewater collection systems are as important as water treatment systems. Wastewater treatment plants can help tackle water pollution only when sewage is conveyed to it by effective wastewater treatment collection. We at IDS Water have all the facilities and much more to connect you with right wastewater collection system providers.
