From then on, the new reservoir system became Paris's principal source of drinking water, and the remains of the old system, pumped into lower levels of the same reservoirs, were from then on used for the cleaning of Paris's streets.
Sejak itu sistem sumber/penampung baru menjadi sumber utama air minum Paris, dan sisa sistem tua, dipompa ke tingkat rendah penampung yang sama, dan digunakan untuk pembersihan jalan-jalan di Paris.
