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 size and type of the system varies according to the number of people served, the

contour and soil type.

The septic tank is a receptacle for

organic wastes from the house sewer. The septic tank decomposes the elements contained in a raw sewage. It combines two processes; sedimentation and anaerobic decomposition or the sludge. As organic wastes are decomposed, the septic tank produces gases in the process, such as methane gas.

The septic tank is constructed with reinforced concrete, and it should be located at a safe distance from the source of potable water, and it should also be airtight.

The Catch Basin

It receives water discharges from the roof and conveys it to the storm drainage line.

It is more or less of the same use as the area drain. It also serves as manhole for cleaning.

Catch basin has a grate on top and a drainage pipe that slopes away from the basin.

This box is set into the ground at a low point on the property. This pipe typically connects to the larger local plumbing system and directs the water to a sewage plant or stream.

Storm drain is a curbside drain with the sole function of collecting rainwater from our

properties and streets and transporting it to local waterways through a system of underground piping, culverts and/or drainage ditches. Storm drains can also be found in parking lots and serve the same purpose.

Directions: Answer the following question below, Use sheet of paper for your answers.

Indicate also the location of the manhole and the manhole cover. After drawing the outline and re-checked your measurements, write down your dimensions and you are ready to draw the reinforcing bars. You may draw your rebar’s covering the whole area of the vault or you can have a portion of it only.

Draw the vertical and horizontal bars for the reinforcement of the septic vault. The standard distances and size of the rebar’s are 12mm Ø for vertical bars and 10mmØ for horizontal bars. For the slabs on top of it would be 10mm Ø spaced at 20cm on both ways of the slab.

Draw only the portion you wish to show the detail of the reinforcements. Indicate now the inlet valve, its position or location and its size, together with the outlet valve.

Draw the outline of the septic vault with your pencil using light guidelines only. As you draw the outline, draw also the thickness of

the sides of the septic vault.

From the plan you have already drawn, project dimensions downward and draw a longitudinal section of your septic vault .Remember the thickness and measurements of the plan should be the same as your section.

With the data on its depth you have gathered, layout the depth of the septic vault, including its foundation and footing. Indicate the location of your inlet and outlet valves which should have a distance from the bottom of the slab of about 30 cm. for the air space and the water level.

Review the drawing, its dimensions and measurements. Finalize the drawing by darkening the lines with a technical pen. Write down the material specifications and construction notes.

Draw vertical and
