To realize this he designed a digester that will fit with the local cold environment of Ifrane and the nature of the nature of the biomass

Each house 3 bulbs of 20 watts which will burn 4 hours daily

The energy required for house lighting =3 bulbs *40 watts*100 families*4hours

=48000wh/day

=48kwh/day.

Number of public lights for street lighting, plant area and bus stop=150

Total energy for public lighting =150*40*4

=24000wh/day

=24kwh/day

Consumption of water/head/day=135 lit

Water consumption/family/day=4 members*135 lit

=540 l/day.

Other uses =135 lit

Total =135+540=675l/day

Total water required for 100 families=100 families *675 lit

=67500 lit

10 % of total water required is for public use =67500*0.1

=6750 lit

Total =67500+6750

=74250 lit

Pumping is done in 4 hours. Pump head is assumed as 20 m.

The pump works for4 hours daily to supply=74250 lit/day

Hence it has to pump =74250/ (4*60*60)

=5.15 lit/sec

Power required for pump=5.15*20*9.81

=1010.43 w

Pump rating=1.01043 kW.
