3.0RENOVATION OF:
3.1 STORAGE TANK
The storage tank at Mamboleo has a wet capacity of 90m3. The tank has been plastered inside and filled the sagging roof. The tank has inlet pipe of 3”. We have now connected the inlet with a float valve to prevent watage of water thru overflowing. The outlet pipeis a 4” HDPE pipe to Karumele with a branch to Mamboleo village. It is intended to construct a small tank 15m3 . This will serve the people of Karumele. /

3.2CONSTRUCTION OF 1BREAK PRESSURE TANK
The construction of the 15m3 break pressure tanks(BPT) at Nkelei is underway. The BPT 15m3 for Karumele is planned in a few days. The BPTs are constructed bigger than a normal BPT to serve as small storage tank. Flow of water in each BPT will controlled by a float valve. /

3.3 RENOVATION OF MAIN PIPELINE
25 Nos of 3” HDPE pipes has been replaced beweet the BPT and the storage tank. Two branchlines have been connected.
The main pipeline is not buried in the ground deep enough in the ground. We discussed with the two village leadership the consequences of pipes being exposed to sunlight and that the whole pipeline should be buried deeply. The response has been discouraging. At the runoff gullies we have constructed traps to filter soil, leaves and grass. This is meant to cover the exposed pipe with the debris. /
