What is a wastewater outfall?
A sewer that receives wastewater from a collection system or from a wastewater treatment plant and carries it to a point of ultimate or final discharge in the environment.
What are the parameters in wastewater treatment?
Biochemical oxygen demand (BOD), chemical oxygen demand (COD), total dissolved solids (TDS) and total suspended solids (TSS) are the most commonly regulated wastewater effluent parameters.
What are the effluent standards?
Effluent Guidelines are national regulatory standards for wastewater discharged to surface waters and municipal sewage treatment plants. EPA issues these regulations for industrial categories, based on the performance of treatment and control technologies.
How does an outfall work?
A marine outfall (or ocean outfall) is a pipeline or tunnel that discharges municipal or industrial wastewater, stormwater, combined sewer overflows (CSOs), cooling water, or brine effluents from water desalination plants to the sea. Usually they discharge under the sea’s surface (submarine outfall).
What is the definition of an outfall?
Definition of outfall : the outlet of a body of water (such as a river or lake) especially : the mouth of a drain or sewer.

What are the factors must be considered while constructing a sewer pipe?
Following factors should be considered before selecting material for manufacturing sewer pipes:
- Resistance to Corrosion.
- Resistance to Abrasion.
- Strength and Durability.
- Weight of the material.
- Imperviousness.
- Economy and Cost.
What is BOD and COD in ETP?
The biochemical oxygen demand (BOD) represents the amount of dissolved oxygen (DO) consumed by biological organisms when they decompose organic matter in water. The chemical oxygen demand (COD) is the amount of oxygen consumed when the water sample is chemically oxidised.
What is the limit of cod?
According to standards of Central Pollution Control Board, permissible value of BOD is 30 mg/l and COD is 250 mg/l.
What is outfall in hydraulic structure?
An outfall can be defined as the set of hydraulic structures between dry land and the receiving water body (Fig. 1) through which waste effluent is finally discharged.
What are the physical parameters of wastewater?
Turbidity.
What are the physical parameters of waste water?
Wastewater has physical characteristics such as temperature, solids, odour and colour. In plumbing work the temperature and type of solids in the wastewater are important considerations. Wastewater at high temperature will affect some piping materials and treatment units such as septic tanks.
What are the requirements of drainage system?
A good drainage system should satisfy the following requirements. Surface water should not percolate to track One of the basic requirements of a good track drainage system is that surface water from rains and adjacent areas should not percolate and seep into the formation of the track.
What factors must be considered before selection of water pipe?
8 Elements to Consider When Selecting Pipe Material
- Material Being Transported.
- Temperature of Liquid Passing Through.
- The Pressure of the Liquid Handling Process.
- Service Life of the Fluid Handling System.
- Ease of Maintenance.
- Exposure to External Elements.
- Valve and Fitting Sizes.
