Soft permeable pombi ipiping system inoshandiswa kudhiraivha uye kuunganidza mvura yemvura, inozivikanwawo sehose drainage system kana hose collection system. Iyo inogadzirwa nezvinhu zvakapfava, kazhinji mapolymers kana synthetic fiber zvinhu, ine yakakwira mvura. Basa guru remapombi akapfava anopindika nderekuunganidza nekudonhedza mvura yemvura, kudzivirira kuunganidzwa kwemvura nekuchengetedza, uye kuderedza kuunganidzwa kwemvura yepamusoro uye kukwira kwemvura yepasi. Inowanzoshandiswa mumadhinaini emvura inonaya mvura, masisitimu emvura emumigwagwa, masisitimu ekugadzirisa nyika, uye mamwe mapurojekiti einjiniya.
