How to treat this??

Bhenc*d me pareshaan hogya hoon mere ghar ka paani me essa kaala mitti jessa segments/sand kyu aara hei, iska kya ilaaj hei? Mere ghar me tank ki safai aur kuch pipe wagera theek karwaye the but problem abhi bhi aara hei. Ab me papa se puchunga toh jwaab ayega khud b kuch karwale. Toh pls aap me se jisse bhi knowlezz ho idea ho for this problem please tell me what to do😭🤦🏻‍♂️. Paani khol ke b chod dia bhaut time tak fir b paani ganda aara hei.
