In order to improve the supply to the PERCHOR reservoir and at the same time delete the tribunal pumping station, a new supply main will be constructed.

For this purpose the PERCHOR reservoir will be connected to the 400 mm main supplying water from the pumpins station to the QUM reservoir.

If the detailed studies reved thzt it would be preferable to construct a new rising main h m the ptlmp station to the PERCHOIR reservoir this solution nilI be adopted.

4). MALAPOA Reservoir

A 1200 d reservoir wiu be constructed to supply the sector of rM%MOX

The water supply n e t w o r k put at the d i s p c s a l of t h e opera to r a t t h e start o f t h s c o n t r a c t includes the f o l l o w i n g facilities :

The pumping stetion is situated on government owned land, in t h e _ ~ r o x i n i t y of the TAGABE . r iver , the land is approxirnctely 100 rn x 30 m ( 3 . 0 0 0 m2).

The pumping s t e t i o n is fed by five sources.

- A spring with a basin immediately adjacent to the o l d pumping ststion.

- Four cased 5ores of 7 6 0 mm dia.

The depth of thsse Sorss varies between 15 rn and 26 m.

S t a t i c water level varies between + 4 m and - il m. Each bore is equipped with a SULZER submersible pumg model K 8 7 / 1 with 2 duty point o f 125 m3/h at 13.5 m htad and a power of 8 . 5 KW.

The submersible pumps discharge i n t o a con tac t / c h l o r i n a t i o n tank o f 650 m3, the tenk is circular and of metallic construction.

The old rectangular contact / chlorination tank is in very poor condition.

The floor l e v ~ I . of t h e tank is at 13.7 m and the overflow is at 1 7 . 4 5 rn.

Chlorination is achieved w i t h chlorine& gas. Chlorination equipment 1s of t h e vacuum / s u c t i o n type.

Water is then pumped to :

- FACIO reservoir by 4 high l i f t pumps. The 4 pumps are SULZER HZ S 126/3 w i t h a duty point of 120 rn3/h, at 7 6 , 4 m head and a power of 37 XW.

- PERCHOIR reservoir by 3 h igh lift pumps. The pumps are SULZER HZ S 126/5 with a duty point of 120 m3/h, at 1 1 4 , 2 m head and a power of 7 5 KW-

The h i g h l i f t pumps, switch boards, a workshop, o f f i c e , chlorination equigmant and sanitary facilities are housed in s. masonry building.

A n o t h e r building houses a generator.

The g e n e r a t o r is driven by s. POYAUD Diesel w i t h a power or' 207 H . P . at 1 500 r.p.m. (170 KW).

2 ) TRIBUNAL PUMPING STATION

The pumping station allows to feed the PERCHOIR rsservoir by pumping f r o m the T~IBUNM., reservoir.

Tht'purnping s t a t i o n is equipped with t w o Ajax E 6 5 - 2 6 pumps with a d u t y point of 100 m3/h et 70 rn head.

The power of each gump is 3 7 KW.

The u r n p i n g mzin between t h e TAGA3E pumping station end t h e F A C I O reservoir is in ductile iron of diametre' 400 mm. It's length is 825 m.

The pumping main between the TAGABE pumping s t a t i o n and the PERCHOIR reservoir is in galvanised steel of 200 mm diameter. It's length is 3113 m.

The pumping main between t h e TRIBUNAL pumping s t a t i o n and the PERCHOIR reservoir is in galvanised steel of 100 mm diameter. it's l e n g t h is 600 rn.

The QUAI reservoir is fed from the FACIO reserv'oir by a d u c t i l e iron gravity main of 400 rnrn diameter. St's l ength is 8270 m.

A gravity feed in galvanised steel of 150 mrn diameter branches from this main to feed the PERCROIR reservoir. It's length is 450 m.

5 ) RESERVOIRS

The network includes 6 cylindrical steel reservoirs situated on fenced land approximately 5 0 m x 45 rn ( 2250 m2) f o r FACIO and 3 5 x 20 m ( 7 0 0 mP) f o r the.qthers.
