  Many of the yet unanswered questions in neutrino physics, such as CP
violation in the lepton sector or neutrino mass hierarchy, could be answered
with higher sensitivity neutrino experiments. New photodetectors based on
micro-channel plates are being developed by the Large-Area Picosecond Photo
Detector (LAPPD) Collaboration. These photosensors have been shown to have
excellent spatial and timing resolution. Using these devices in massive water
Cherenkov detectors, we could significantly improve the vertex resolution for
neutrinos enhancing background rejection for neutrino oscillation experiments.
We present preliminary results on the reconstruction capabilities for single
particles in water Cherenkov detectors using fast photosensors.
