Draft Sanitary and Storm Drainage System

The sanitary installation is referred to as the network of pipes and fittings that carry off wastes and each plumbing fixture is titled with the appropriate pipe and fitting. The discharges are conveyed to the septic vault. The storm drainage system, on the other hand, consists of pipes, fittings, catch basins, area drain and is intended for getting rid of water from the building roof and it’s surrounding and is conveyed to the street sewer. The storm drainage is considered part of the plumbing system.

The pipe used for sanitary and storm drainage most common to homeowners and

contractors are the plastic pipe or PVC pipes and the concrete pipe for area drain.

Skills Assessment

Direction: Listed below are some of the most important skills that you must gain in order to Draft

Sanitary and Storm Drainage System. On the right side of the matrix lists the skills expected of

you to master. Rate yourself by checking “Not much”, if you are not so familiar yet, “A little” and/or

“A lot”, if you are already familiar with the skills. Don’t feel bad if you checked “Not Much” in all of

the skills. Keep in mind that this is being administered to determine your pre-entry knowledge of

and skills on the lesson to be presented.

Distribution System?

Overview

Wastewater is discharged by gravity through the disposal system. All pipes in this system

therefore must slant in a downward direction so the weight of the waste will cause it to move down. Because of this gravity flow, waste lines are larger than water lines. The stacks are the vertical lines while the branches are the horizontal lines. Vents are also provided for air circulation and to permit sewer gases to escape through the roof. This equalizes the air pressure in the drainage system.

The wastewater flows starting at the fixture trap, which is provided to stop gases from

entering the building and each fixture has a separate trap or seal to prevent backflow of sewer gas, through the fixture branches to the main sewer line.

Waste stacks carry only wastewater while solid wastes runs thru the soil lines, which are

the largest in the system and are flushed with water after each use.

Piping systems are vital to modern society. Some systems may be complex; others may be simple such as in a residential dwelling unit. But they share some common elements, whether they are steel, plastic, copper pipes, or tubing.

Sanitary and storm drainage for

residential dwelling are either wrought iron pipes, Polyvinylchloride (PVC) pipes and for drainage is either concrete pipe or PVC pipe. The more common today is the un plasticized Polyvinylchloride (u PVC) pipe.

Polyvinyl pipe and fittings are

available in commercial length of 3.0 meters and also available in schedule 40 and 80. They are usually assembled with slip joint fittings and solvent, both PVC and chlorinated Polyvinylchloride (c PVC) pipes are commonly available in sizes ranging from ½’ to 4” inside diameter. The Sewage Disposal System

Absence of a good sewage

disposal system can result to contamination of water and water-borne diseases. It is important to value a good disposal system. There are different types of sewage disposal system, from the old to the more scientific ones;

1. Cesspool

2. Privy

3. Septic Tank

4. Public Sewer line

The sanitary system is of two types; the intercepting and the tributary or contributing

sewer. The intercepting type is constructed with concrete pipes while the tributary sewer is laid in

an open trench and is made of vitrified clay or bricks.

The Septic Tank The septic system converts solid

wastes into liquid by bacterial action. The wastes flow into a septic tank some distance away from the house. The liquid waste flows thru to the sewer line while the sludge remains at the digestion chamber of the tank.

The septic tank is constructed with

reinforced concrete, it should be located at a safe distance from the source of potable water, and it should also be airtight.

The size and type of the system varies

according to the number of people served, the

contour, and soil type.

time, your will prepare for

final graded performance

below. But before that

answer first the following

questions prepared for you

in the generalization.

Indicate the location of the different sanitary fixtures by drawing their symbols on the area where they are best located. Then draw the layout, gray water collection should be connected to the catch basin or directly connected to sewer line and the septic vault with the sewer line connecting to the street sewer.

After drawing the layout,

you will now indicate the

different pipes and fittings

used by the drawing thier

symbols on the sewer line

layout and write down also

the material specs for the
