Project Overview
18-property portfolio retrofit across Los Angeles
Planet Optima has replaced 13,668 low-efficiency toilets across GHP Property Management’s 18-property Los Angeles portfolio, an ongoing retrofit under the LADWP / MWD High-Efficiency Toilet Rebate program. 3.5 GPF fixtures were swapped for 1.0 GPF WaterSense-certified units, with low-flow showerheads and aerators added throughout. Work continues as new properties come online.
LADWP covered 100% of equipment, installation, and removal at every site. GHP signed one master authorization; Planet Optima handled eligibility, paperwork, scheduling, and rebate processing across the entire portfolio.

Does Your Building Qualify for the LADWP Program?
LADWP funds the whole toilet replacement for buildings that meet four conditions. After 500,000 fixtures we know exactly what decides it.
- Inside LADWP service territory The building takes its water from LADWP, not a neighboring city utility. The water bill settles it in a minute.
- 5 or more residential units Multifamily and commercial properties with 5 or more units. Portfolios are checked building by building.
- Toilets at 1.6 GPF or higher Fixtures on the old standard, typical for buildings completed before 2014. LADWP pays up to $300 per qualifying toilet.
- An owner or manager who can sign One authorization form is the whole ask. Planet Optima files everything after that.
