If end date of the baseline year/period is 2004 or earlier, provide:

A brief description of when and why the water use baseline was adopted:

2016 is when full billing records/data for all entities (e.g. auxiliaries) was more or less complete in terms of tracking and 2017 is year from which the 5 year Water Action Plan (2018-2022) is based.

Optional Fields

A brief description of the institution's water-related behavior change initiatives:

As part of the Office of Sustainability's regular "Take Charge" pledge messaging, "Watch Waste" (reporting leaks and other facilities maintenance issues) is a key component of the five step pledge.

A brief description of the institution's water recovery and reuse initiatives:

Central Plant piloted an innovative condensate capture system which collects waste water for reuse in the cooling towers.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

Major water savings was the demolition of Small College in 2018 which constituted the oldest buildings on campus and had several leaks.

Per Water Action Plan, any replaced fixtures are updated to the current CalGreen standards which greatly increases water efficiency when retrofits occur.

Data source(s) and notes about the submission:

96%+ of CSUDH's landscape is irrigated with reclaimed water. Potable water usage has greatly decreased since the implementation of WaterScope metering monitors on all campus buildings which alerts Facilities Services automatically when there is a detected leak.
