We present a method for  the construction of compactly
supported $\left (
1 & 0 & -1\\
1 & 1 & 0 \\
1 &  0 & 1\\
\right )$-wavelets  under a mild condition. Wavelets inherit the
symmetry of the corresponding scaling function and satisfies the
vanishing moment condition originating in the symbols of the scaling
function. As an application, an  example is  provided.
