The capture dam was build with dirtbags and plastered with cement. Underneath the cement is a plastic lining. Different size stones were used as a debris filter.

Die hmelwater opvangdam is gebou met sandsake. Binne is daar 'n laag plastiek en uitgepleister met sement. Ons het tot dus ver nog nie 5 sakke sement gebruik nie. Vir filter doeleindes is daar verskillende lae klippe gebruik.
vriendelike groete
