URoca usungule umxholo omtsha wegumbi lokuhlambela kwimarike: the W + W, edibanisa izinto ezimbini ezibalulekileyo kwisiqwenga esinye soyilo: indlu yangasese nesinki. Ngale ndlela, uphawu oludumileyo lwe-sanitaryware lukhethe into ethi, ngaphandle kokuphulukana neyonaestestics yanamhlanje, yenza ukuba kufumaneke indawo kwezona zincinci zangasese.
Kodwa i-W + W ayibonakali kuphela ekusebenzeni kwayo xa kuyilwa igumbi lokuhlambela. Inenye into ebaluleke ngakumbi: ukudityaniswa kwezinto zombini kwisiqwengana esinye kwenza ukuba kube lula ukufaka isicelo se- ubuchwepheshe bokusetyenziswa kwakhona kwamanzi okuzinzileyo.
Esi siqwenga siqokelela amanzi asetyenziswa esinkini ukugcwalisa itanki yangasese. Ikwanayo nenkqubo yokucoca eqinisekisa umgangatho osemgangathweni wamanzi asetyenzisiweyo. Ngale ndlela, ukusetyenziswa kuyehla nge-25%, edibanisa ukonga uqoqosho ngokukhusela okusingqongileyo.
