Ukukhethwa kwephampu yamanzi yomthombo womculoidinga ukucabangela izici ezilandelayo:

1. Izidingo zobude nokugeleza komthombo: Khetha iphampu yamanzi efanelekile ngokusekelwe ekuphakameni nokugeleza kwezidingo zomthombo.

2. Izidingo zekhwalithi yamanzi: Uma kuwumthombo osetshenziswa ezindaweni zomphakathi, kuyadingeka ukukhetha iphampu yamanzi ehlangabezana nezindinganiso zikazwelonke ukuze kuqinisekiswe ukuphepha kwekhwalithi yamanzi.

3. Ukuqina Nokuthula: Ukukhetha iphampu yamanzi ehlala isikhathi eside futhi enomsindo omncane kungagwema ukushintshwa okuvamisile nomsindo.

4. Umnotho: Kuyadingeka ukucabangela intengo kanye nezindleko zokusebenza zephampu yamanzi bese ukhetha iphampu enezindleko eziphakeme eziphezulu.

5. Idumela Lomkhiqizo: Ukukhetha uhlobo oludumile lwepompo yamanzi kungaqinisekisa ikhwalithi yomkhiqizo kanye nesevisi yangemuva kokuthengisa.

Ngamafuphi, ukukhetha iphampu yamanzi yomthombo womculo kudinga ukucatshangelwa okuphelele kwezici ezingenhla, futhi ekugcineni ukhethe ipompo yamanzi efanelekile.
