A sewer pipe is a conduit for the elimination of waste materials. The primary purpose of a sewer pipe is to transport wastewater or sewage from homes or commercial buildings through the sewer system for treatment or disposal.

• Asbestos Cement (AC) Sewer. Asbestos Cement (AC) Sewers are manufactured from a mixture of cement and asbestos fiber.
• Brick Sewers. Brick Sewers are made at site and used for construction large size sewer.
• Cement Concrete. i.
• Cast Iron (CI) Sewers.
• Steel Sewers.
• Plastic Sewers.

Sewer lines have been used all over the world for centuries but have evolved a lot over the past few hundred years. Until the late 20th-century, most sewer pipes were made of wood, cast iron, fired clay, or fiber conduit. No matter what they were made of, sewer lines were built to last at least 50 years.

In larger homes where more than one main line runs out to the municipal sewer service, it’s possible there will be more than one sewer clean-out fitting. In warmer climates, the clean-out fitting will be located outside the house, usually close to the foundation, and will be set at ground level.

Most home sewers are 4″ inside your home itself, and as they run under your property as well. It is typical in many areas, such as NYC, that the size of the pipe itself increase to 6” as it exits your property line.

It’s usually located outside your property boundary, often under a public pavement or road. A lateral drain might run under your property if you share a sewer with your neighbour. Most sewers are publicly owned and are maintained by your water company. However, there are still some privately owned sewers.

The drain system within your home works entirely by gravity, allowing wastewater to flow downhill through a series of large diameter pipes. All wastewater flows to the main waste and vent stack. The main stack curves to become a sewer line that exits the house near the foundation. In a municipal system this sewer line.

There are three types of modern sewer systems: Sanitary sewers (also called foul sewers), storm sewers (also called surface water sewers), and combined sewers.

In the US, with modern regulations, in most municipalities, yes, they do. The water and solids from your toilet waste line and the water from your drains end up in the same sewer line, if you have access to a municipal sewer system.

Treatment Steps

• Step 1: Screening and Pumping. The incoming wastewater passes through screening equipment where objects such as rags, wood fragments, plastics, and grease are removed.
• Step 2: Grit Removal.
• Step 3: Primary Settling.
• Step 4: Aeration / Activated Sludge.
• Step 5: Secondary Settling.
• Step 8: Oxygen Uptake.
• Sludge Treatment.

Important Methods in Water Management Methods of water management can be classified as Conservation, Allocation, retrofit program and Behavioral practices.

When wastewater arrives at the treatment plant, it contains many solids that cannot be removed by the wastewater treatment process. This can include rags, paper, wood, food particles, egg shells, plastic, and even toys and money.

Water Resources Management (WRM) is the process of planning, developing, and managing water resources, in terms of both water quantity and quality, across all water uses. It includes the institutions, infrastructure, incentives, and information systems that support and guide water management.

Describe various methods of water management​

• Dams:- It control the obstruct flow of water from water body
• Rainwater harvesting :- It is one of the useful method for conserving water.
• Drip irrigation :- The method is mostly used in the north – eastern States.

Utilization of the resources Water management helps in developing efficient irrigation practices for the betterment of agriculture in the country. Proper utilization of water in our homes too can save this precious resource. Water management teaches us to use a limited amount of water whenever required.

Water management is the control and movement of water resources to minimize damage to life and property and to maximize efficient beneficial use. Good water management of dams and levees reduces the risk of harm due to flooding.

Integrated Water Resources Management

• Water stress, droughts and floods, including impact of climate change.
• Catchment management and ecosystem services on different scales.
• Large-scale nature-based solutions and biodiversity.
• Water rights, trading and partnerships.

Water resources management encompasses the efforts of stakeholders to protect freshwater ecosystems that provide drinking water. Water is a vital resource not just for humans, but also for a variety of aquatic ecosystems, including wetlands, watersheds, rivers, estuaries, and coastal areas.

Planning, developing, and managing water resources to ensure adequate, inexpensive, and sustainable supplies and qualities of water for both humans and natural ecosystems can only succeed if we recognize and address the causal socioeconomic factors, such as inadequate education, corruption, population pressures, and …

Here are the main five water sources:

• Municipal.
• Ground water (well)
• Surface water. Lake. River. Stream (creek) Shallow well.
• Rainwater.
• Seawater.

There are a total of three natural sources of water. They are categorized as: rain water, underground water and surface water. Here is a look at each and what supplies these sources. Rain water includes other sources such as snow and additional types of precipitation.

3.1 Types of water source. In Study Session 1 you were introduced to the three main sources of water: groundwater, surface water and rainwater.

The largest natural source of water is none other than glaciers. They are melting at each and every point of time thus contributing a lot in maintaining the overall level of rivers as well as dams.
