Water for Village in Sanan (2)

1. Design

a. System (Water-Net sytem)

This clean water-net system plan is using two different systems, well-suited with the topography condition in the area and community population which will be served by the system.

v Area of RT 06 and RT 07 including Segoroyoso

	Well

Picture 1

Water-Net Distribution System RT 06 and RT 07

Including Segoroyoso Sanan, Bawuran

Water will be pump by using P1 pump into R2 water reservoir. From R2 water reservoir water will directly distributed by using P2 pump into R1 water reservoir for being distributed for 19 households plus 71 households for RT 07 and Segoroyoso, half of the water will be pump into the same pump into the same R3 water reservoir for being distributed for 19 households.

The water distribution control into R1 or R3 water reservoir will be done by using tap which putting on pipes to R3 water reservoir (Lower than R1 water reservoir). This system planned by using software water-net and already has been tried. The result is that the water succeeds to be distributed equally for the community and they don not have to queue in getting water for their daily need in public well where the location is enough far from their house. The need of water for the family and their cattle are already sufficient and each community could get the water directly from the water reservoir. There are some efforts that have to be done to make the system become perfect:

· Make new well with the depth more or less is 15 m which aimed to enlarging reservoir volume

· Replace water reservoir with permanent structure by using framed concrete structure.

· Enlarging water pump capacity into 1 liter/second and the equipment.

· Enlarging existing booster pump for 1 liter/second and the equipment.

· To round off power supply network system for all water pump into secure condition.

· To round off pipe network into secure condition (under ground).

· Install chlorination unit to purify water before distributed to the community.

· Installment of water meter, tank / water storage for each household.

· Capacity building unit organization user of safe water beneficial user.

v For area RT 03, RT 04, and RT 05

Picture 2

Water-Net Distribution Plan System RT 03, RT 04, and RT 05 Sanan, Bawuran

Water will be pumped from the deep well with around 100 meter depth in the village land, then by using submerge pump water P3 will be pumped out into reservoir R4. From this reservoir R4 some water will be pumped into reservoir R5 to fulfill 42 household and some more will be pumped out into reservoir R6 to be directly distributed for 31 household. RT 03 community for 25 household will be distributed water from reservoir R7 which supplied by reservoir R6.

The program will cover for arranging deep well, water pump, distribution network including pipe, reservoir, creating water management organization, training for water source management and hygiene promotion.

b. Detail Measurement

v Water needs

Water need by one man in one day is 100 liter/man/day. For each household, it is assumpted in 1 household consist of 5 members.

Water needed for one household in one day :

= 100 liter/person/day x 5 person

= 500 liter/day

Tabel 2

The need of Water in RT

Are	Number of Population 2007 (person)	Number of Population 2012 (person)	The need (liter/day)
RT 03 RT 04 RT 05 RT 06 RT 07 and Segoroyoso	125 210 155 190 355	129 216 159 195 364	12900 21600 15900 19500 36400

v Building Dimension and Facility

· For area RT 06 and RT 07 including Segoroyoso

In this area is planned using 3 reservoir, such as R1 reservoir, R2 reservoir, and R3 reservoir which is each of the reservoir will served the need of water for different community.

Tabel 3

The Need of Water which Served by Reservoir for RT 06 and RT 07

Including Segoroyoso

Area	Reservoir	Number of Households	Need (l/d)
RT 06 RT 07 and Segoroyoso	R2 R3 R1	- 19 90	- 9750 46150

Reservoir dimension which will be design will suit the need of water volume which will be served. Because of R2 reservoir is serving 2 reservoirs, such as R1 reservoir and R2 reservoir, so that the dimension from R1 reservoir must be larger than other reservoir.

· For Reservoir R2

Reservoir dimension using 3 x 2 x 2 m = 12 m³

· For Reservoir R3

Reservoir dimension using 2 x 2 x 1 m = 4 m³

· For Reservoir R1

Reservoir dimension using 2 x 2 x 2 m = 8 m³

· For area RT 03, RT 04, and RT 05

There were planned 4 reservoirs in this area: R4 reservoir, R5 reservoir, R6 reservoir, and R7 reservoir where each will serve different need of water for the community.

Tabel 4

The Need of Water which Served Reservoir for RT 03, RT 04, and RT 05

Area	Reservoir	Number of Households	Need (l/d)
RT 04 RT 05 RT 03	R4 R5 R6 R7	21 21 31 25	10800 10800 15900 12900

Reservoir dimension which will be designed will suitable with the need of water volume that will be served. Because of R4 reservoir served 3 reservoirs which are R5 reservoir, R6 reservoir and R7 reservoir, so then the dimension from R4 reservoir have to be larger than other reservoir.

· For reservoir R4

Reservoir dimension using 4 x 3 x 2 m = 24 m³

· For reservoir R5

Reservoir dimension using 2 x 2 x 2 m = 8 m³

· For reservoir R6

Reservoir dimension using 3 x 2 x 2 m = 12 m³

· For reservoir R7

Reservoir dimension using 3 x 2 x 2 m = 12 m³

2. Social Activity

a. Management Organization

Clean water-net system management will be handled directly by the community.

b. Training for Implementation and Maintenance

By improving the ability of the community management to ménage the water together so that could develop, operate, maintain the water-net system installation which will be established so that the water-net system could be develop and could fulfill the community’s need of clean water.
