Nepo DOE yakabudisa zvinodiwa muna 2017, zvakatanga kushanda muna July 2021. Kubva ipapo, kuiswa kwedziva kutsva uye kutsiva DPPP kunoda shanduko yekumhanya yepombi uye motokari.

Kune zvikomborero zvevaridzi vemadziva uye zvakatipoteredza.Kunyange zvazvo mapombi ekumhanya anogona kuva nemutengo wepamusoro wekutanga, iyo ichachengetedza mari munguva refu.Iko kushanda kwesimba-inoshanda kweiyo speed speed motors ichapa mubhadharo.DOE inofungidzira avhareji yehupenyu-kutenderera mutengo wekuchengetedza kune varidzi ve-ivhu madziva emadhora zviuru zviviri nemazana mana nekubhadhara kwerisingasviki gore.

Pakatanga kushanda murairo, zvinhu zvaivepo zvepombi dzisingaenderani zvaive zvichiri kubvumidzwa kutengeswa nekuiswa.Replacement variable speed mota mitemo ichiri kumirira kusvika 2021 Chikunguru.

Kwemaawa mashoma zuva rega rega,pombi dzedzivainoda kushanda nekumhanya kwepamusoro kupa huwandu hwekuyerera kwepamusoro kusanganisa nekuchenesa.Kwezuva rose, pombi inongoda kutenderera mvura kuburikidza nefiltration system pane yakaderera kuyerera.

Motokari imwe chete inomhanya-mhanya pane imwe sipidhi kwenguva yakareba sezvainobatidzwa.Pane mabhenefiti ekuchinja anomhanyisa dziva pombi mota.Iyo inosiyana yekumhanyisa mota inogona kupa simba pombi nekumhanya kwakasiyana, zvichienderana nenguva kana mashandisirwo.Iyo DOE inofungidzira kuti akasiyana-speed pombi anogona kucheka kushandiswa kwesimba ne70 muzana pane imwechete yekumhanya pombi.Variable speed pump motors vanogona kushanda nekumhanya kwakaderera kwezuva rose apo pombi iri kutenderedza mvura yekusefa.
