Ayon sa Maynilad, kailangang gawin ang shutdown dahil ang PWTP ay idudugtong sa bagong water treatment facility ng Maynilad na ginagawa sa lugar.
Sa sandaling maisakatuparan na ang interconnection inaasahang maaayos ang serbisyo ng Maynilad sa mga customers nito sa southern portion ng West Zone concession.
Dahil sa shutdown maraming lugar sa Las Piñas, Muntinlupa, Parañaque, at Cavite ang makararanas ng mahinang suplay hanggang sa tuluyang pagkawala ng tubig mula alas 11:00 ng umaga ng June 6, 2018 (Miyerkules) hanggang alas 5:00 ng umaga ng June 8, 2018 (Biyernes).
