Multi-family water conservation project
This West Hollywood building was designed in accordance with Los Angeles’ Green Building Ordinance, which aims to create more sustainable infrastructure. Design elements include, but are not limited to, bedrooms located on the street side to maximize natural light, native and drought-tolerant landscaping, a computer-controlled irrigation system, and two photovoltaic panels along the side of the building which provide all of the power for the building’s common spaces.
In November of 2020, Planet Optima completed a project to compliment the existing water and energy efficiency features of the building. The scope of the project was to replace the apartments’ 1.6 gallon per flush (GPF) toilets with new 0.8 GPF High Efficiency Toilets (HET). The reduction of water per flush is 50% for each of the 45 toilets replaced. Over a period of one year the replacement of these fixtures will result in estimated savings of 48,384 gallons based on the amount of times the average American flushes per day.
This is a small scale example of the projects Planet Optima has completed throughout Los Angeles County. We take pride in participating in the effort towards meeting the State’s water conservation goals; whether on a 45 toilet project or a 2,200 toilet project.

Planet Optima developed an implementation plan that would substantially reduce the water consumption at a villa complex in Woodland Hills.
In October of 2018, Planet Optima successfully completed the replacement of 550 1.6 GPF toilets with newer, High Efficiency 1.0 GPF models that save 37.5% gallons of water per flush. Through MWD/LADWP program funding, Planet Optima was able to provide this solution at No-cost for the property.
When comparing water usage in May of 2018 (pre-upgrade) with December of 2018 (post-upgrade), the villas saw a 25.2% decrease in usage and a 22.8% reduction in costs. This translates to the conservation of 373,252 gallons and $4,809.26 during the course of a month. From these numbers, we project an approximate saving of $57,711.22 and 4,479,024 gallons per year, resulting in a total of $577,111.20 and 44,790,240 gallons saved over 10 years.

Planet Optima upgraded 1,844 1.6 gallon per flush (GPF) toilets with 1.0 GPF High Efficiency models in August of 2020.
The water conservation retrofit was provided at no-cost for the property through MWD/LADWP program funding.
Occupancy fluctuates at this complex as it caters to university students, savings and efficiency calculations were adjusted accordingly.
Water efficiency increased by 15.61%, 282 HCF, or 211,141 gallons for January.
Using this data to extrapolate, the site will save $372,000 and 30,482,496 gallons over the next 10 years.
A one-to-one comparison of pre and post installation bills from the month of January demonstrates a 21.24% reduction on the January water bill from 2020 to 2021.

Multi-family water conservation project
The units at this Warner Center property were special in that they required shorter toilets due to the presence of counter tops. Planet Optima sourced the 2,107 specialty toilets and completed the water conservation retrofit at no-cost for the property through MWD/LADWP program funding.
Water usage after the retrofit decreased significantly relative to the same billing period of years before the installation of HET toilets.
