OBJECTIVES

• The Various Type of Drainage Technologies.

• The Various Methods Used to Prevent Water

Infiltration on the Ground.

• The Local Authorities’ Requirement For Drainage

Design and Construction.

• The Construction Method of Drainage.

THE VARIOUS TYPE OF DRAINAGE TECHNOLOGIES

• CORRUGATED DRAIN PIPES

• FRENCH DRAIN

• RELN STORM MASTA ®

CORRUGATED DRAIN PIPES

• A corrugated pipe is a tube with a

series of parallel ridges and

grooves on its surface. This pipe

can be manufactured of steel or

plastic such as high-density

polyethylene (HDPE) or PVC. It

can be coated or lined. Corrugated

pipe is used in applications such

as drains where flexibility,

durability, and strength are

important attributes.

FRENCH DRAIN

• A French drain can have

perforated hollow pipes along the

bottom to quickly vent water that

seeps down through the upper

gravel or rock.

• The common features of these

systems include a lightweight

gravel substitute that is wrapped

around perforated corrugated pipe

and covered with commonly used

filter fabric.

RELN STORM MASTA ®

• The Reln Surface Water Drainage System is a

complete solution for the collection and

dispersal of surface water. Typical applications

include around patios, swimming pools, sports

courts, and gardens, across driveways, along

pathways and retaining walls, in fact any area

where surface water collects.

• It can connect the Reln Surface Water Drainage

System to 90mm stormwater pipes.

• All components are tough, durable, single-

piece mouldings.

• Easy to install.

• 80% Plastic(Drain body), 10% Galvanized

steel(Grate cover).

METHODS USED TO PREVENT WATER INFILTRATION ON

THE GROUND

Geotextiles or Dam Proof Membrane

• Purpose of geotextiles for drainage is to allow water to pass and in the special case of drainage in transmission.

• Geotextiles can be used to improve subsurface drainage by removing groundwater from chronically soft, muddy sections of a road, a landscaped area or an embankment.

• Drain consists of a trench filled with gravel and/or perforated plastic pipe.• The trench is designed to intercept the groundwater and drain it to a lower

spot.• Geotextile also acts as a barrier between the gravel and surrounding soil

Cement Mortar

• Mortar is a paste used to bind blocks together while filling the spaces between them.

• Mortar cement will be used as a material to prevent water infiltration on the ground if have a crack or hold at precast concrete.

• Use to repair when the original application has crumbled or washed away.

• Mortal also used as jointing between gaps drain to drain.

Channel Sealing Method

• Build drainage especially at hill area for engineering work to avoid from landslide.

• Asphalt will use at a first layer, it function to prevent water infiltration on the ground.

• Second layer is filled sand and then gravel. • This method drainage usually more economical.

LOCAL AUTHORITY REQUIREMENTS FOR DRAINAGE DESIGN

AND CONSTRUCTION

STREET, DRAINAGE AND BUILDING

Figure 1: Jabatan Perparitan dan Saliran. Source (http//water.selangor.gov.my/)

Local authority to construct and maintain drains and water-courses

The local authority may cause to be made and constructed and maintained surface and storm water drains, culverts, gutters and water-courses.

If necessary the local authority may request the State Authority to acquire any property in accordance with any law.

For the purpose of subsection (1), in relation to the Federal Territory reference to the State Authority shall be construed as reference to the Government of the Federation.

Penalty for making unauthorized drains into canal or stream

Any person who without the prior written permission of the local authority:

i. Makes or causes to be made any drain into any of the drains or into any canal or stream under the control of the local authority

ii. Closes up stops or deviates any drains.

• Shall be liable on conviction to a fine not exceeding one thousand ringgit, and a Magistrate’s Court on the application of the local authority.

Local authority may recover cost of improving and making drains, etc.

Determining the respective amounts to be paid by the frontagers or developers, the local authority may take into consideration:

i. The area of their respective premises.

ii. The condition of the land, before, during and on completion of development.

iii. Any other matters which in the opinion of the local authority are relevant and proper to be considered.

METHOD STATEMENT OF

STANDARD DRAIN CULVERT

METHOD STATEMENT FOR DRAINAGE

1. Site Survey

Surveyor to set out of points

and establish of Temporary

Bench Mark (TBM) level.

Positioning of point will carry

on based on construction

detail drawing from the

engineer. 

2.Site clearance

Site need to remove all of the

vegetation and stumps that

will disturb the construction

process.

3. Excavation

Excavation of drainage

according to drawing

specification need to be

carried out.

4. Setting out for drain

After excavation has been

done. Setting out for the

drainage need to be carried

out with depth 1425mm and

width 1200mm.

5. Formwork installation

Installation of formwork need to

be done before concreting

work are carried out. Fully

support for formwork structure

are need to make sure

formwork are not collapse.

6. Sand blinding

This compacted sand act as a

cover for the drainage. the

specification are include in the

drawing that depth 150mm,

width 1200mm and length

1900mm.

7. Reinforcement

installation.

Reinforcement need to be

install before of concreting

work. Based on this drawing,

reinforcement steel Y10 are

used.

8. Concreting work

Concrete grade 20 are used

in this drainage work.

9. Lay the U-Drain

Based on the drawing, U-

Drain are used for this type of

drainage. U-drain are made of

ceramic and it also not

durable for rugged work this

too easy for broken.

10. Concrete mass

Concrete mass need to be

lay surrounding the U-drain

for the protection purposed.

with this concrete mass layer

it will prevent the U-drain

from the crack or broken.

11. PVC Weephole

Install PVC Weephole 230mm

x 230mm x 300mm every 3m

alongside of the drainage to

allow the underground water

flow into the drain.

12. Concrete cover

Concrete cover are made of

reinforced concrete. This are

used to cover the drainage

from any foreign material into

the drainage and will blockage

the flow of water.

13. Drain trap

Drain trap are 1200mm x 150mm.

every 3m need to leave avoid 400mm

x 400mm for water from the above

flow into the drain.

14. Backfill

Backfill the drainage and compact the

sides.

METHOD STATEMENT FOR DRAINAGE

CONCLUSION

• A proper drainage control can help prevent the worrisome effects

of water damage. Both residential and commercial buildings are

often equipped with some type of drainage system.

• The choice usually comes down to whether the drain will be

premade or constructed at the site. This will depend upon the

type of land and how high the budget is. Some of the most

common types of drainage control systems include French

drains, trench drains, and sump pump pits are used for drain

water surface from their housing lawn.
