LOCAL ASSOCIATION
« JARDIN FAMILIAUX-TOURNE SOL- »

Rodrigues Jérémy
In collaboration with :
Alexandre Catala

Grimont Louis

Problematic

How supply a lighting and watering
system about a garden local with
renewables ressourcers ?

For who? Where ? How ?

Solutions

Submerged Pump

pump

Dimensioning Calculation
The differential head
HMT = (0.58 + 0 + 12.4 ) + 5 = 17.98
Need determine the water flow :
-> Rune time per day : 1h
-> Capactity of the container: 323 L
The water flow wille be : 323 L/h
The product range of pump more apropriated is the 8000 Series Diaphragm Pumps.
The pump we’ve chose
Shurflo Pentair 5050-2301-C011
Caracteristics:
-> Water flow max : 18.9 L/min
-> Pressure max : 4.5 Bar
-> I max : 13 Amps
-> U : 12 V inDC

Section of Power Cable
Protection Fuse

Type grid : Independant Domestical Grid

We will choose a cable of 6mm²

Grid : single phase
Voltage : 12 V
Current max : 13 A

Length of cables : 2 m

The protection fuse kept ESKA 1.038.730 :
- 16 A
- 1000 V
- DC
- 10.3 mm Ø ; 38 mm de L
- AM

Set- up of the Float switch
«What is the goal to use a float switch ? »
Turning on an hydraulic pump during it is empty is very bad for it. Doing that you can
break the engine. That’s why I’ve chosen to include a security which detect the level of the water in the
container.

For a variable voltage we see that the pressure between
0.7 à 2.75 bars. We need 1,7 bars for the pressure so this pump answer to
requirement.

Economic record
• Pump :

280 €

• Container of water 300 L:

100 €

• Canalisation 200 m :

150 €

• Spray of irrigation :

10 €

• Float Switch :

15 €

• Flow meter :

20 €

• Pressure switch :

50 €

• Protection fuse :

13 €

• Cables :

5€
Total : 643 €

Return on investment
With a consomation in one year of : 323 x 365 = 117895 L
Calculing with of the price of the « Syndicat des eaux » : price of m^3 = 3.54€
117895 L = 117 m^3
117 x 3.54 = 414 €
Cost Projet : 643 €
Economie / year : 414 €
Return on investment : - de 2 ans
We respect the specifications

Ecological report

Source of graphic: website « bCo2 cycle of life »

The first part of the graphic is the grey field : it represent :- extraction
- production
- transport
The electricity is free because it comes from solar panels & windturbines.
The is free becaus it’s the recuperation of the rainning water.
The total carbon print of my project is : 18 kg of CO2 ejected.

END

Thank’s for listenning !
