*The writers choose the title because he want to designing

drainage system and run off infiltration chambers in Griya

Mapan Housing, Sumenep.

*The background from the thesis is :

* In the modern era the needed place to lie it!s so high, many

green area has been changed to housing place. So the greenarea it!s gone and the water can!t infiltrate to the soil.

Hydrology "ycle more difficult . The impact of this can make

area is flooding. #ot only flooding but also erosion. It!s

dangerous.

*$rainage System and %un &ff Infiltration "hambers canresole this situation. So in the Housing 'lace must hae a

good drainage system and run off infiltration chambers.

*"onclusion :

* The tittle and the background is sustainable. (rom the

background we will know the writers want to make agood drainage and infiltration chambers for a housing

place. To reduce natural disasters and make water

storage in soil.

*The scope of this thesis is :

). The location of this pro*ect is Griya Mapan Sumenep.+. The area of Griya Mapan Sumenep is .-Ha.

. The calculation of water runoff *ust including waste water

from household and rainwater.

. This planning use a rier for final disposal.

-. This pro*ect will use base price from Sumenep.0. 1sing coefficient from S#I and HS'

2. $idn3t calculate the stability of soil.

4. The cost of accumulation data will be ignored.

*7bstract:

The growing Griya Mapan Housing comprising +8 houses

doesn!t hae a proper drainage system yet. Therefore, a drainagesystem planning completed with runoff infiltration chmabers are

designed.

Topographic map and rainfall data of 9alianget, 'rasanga and

Gapura stations are needed for designing. (ormulation og 'earson

III was applied to calculating the rainfall data with )8;year cycledperiod.

The design results in 2 dimensional channel consisting types

$);$2 with +8 infiltration chambers diameter 8.4m and +.-m

deep. 6ith total costs .
