 A ferrocement cistern made was built to impound water for my personal use. The size and pattern were taken from the publication of the International Ferrocement Information Center DO IT YOURSELF SERIES. When the city suffered drought and there was water rationing, the tank played an important role it was very useful. During rainy days, it also serves as rainwater collector tank. The 1.2-cu.m of ferrocement water tank is more than enough to serve the weekly water requirement of my family of 8 person for drinking and washing of clothes. The booklet, DO IT YOURSELF SERIES, helped me a lot.





Initially, as a Civil Engineer, I disagree with the specifications in the booklet because it differed with the minimum standards on reinforced concrete structures until I tried to make one. While I was constructing the tank my neighbors were curious probably because of the very thin wall thickness, which was 25 mm that I used. Others presumed that I am making a culvert. Amazingly, when the tank was 100% completed, a hydro testing was conducted and no leakage was observed. Then, lifting the tank and then dropping about 1 m above the ground initiated an impact test. After which, it was rolled on the ground and intentionally allowing it to bump into hard objects then, another hydro test followed. Again, it did not exhibit leaks and cracks. Other observations include: the water in the tank is cold even during summertime; moss grows, mint green in color, an indication that humidity exist but is easy to remove; no indication of rust yet; sediments about 5-mm thick were present during weekly cleanup; and water tastes good and crystalline in color. In conclusion, I could say that using the cistern ferrocement made is environmental-friendly, cheaper than other water tanks of made of other materials. As an experience user of ferrocement water tank, I am highly recommending its use.
