CSUN Sustainability 2020

  • Water on gray background

Water

CSUN is located in a region characterized by an insufficient supply of local water to serve its population. CSUN’s commitment is to be a good steward of water resources, and to conserve wherever possible.

Main Strategies

  1. Improve conservation practices and reduce water consumption
  2. Improve data collection, management and analysis
  3. Increase awareness of water as a valuable resource and educate on water conservation principles

Objectives for 2023

  1. 15% reduction in water consumption
  2. Measure, record, and analyze water consumption on a facility level
  3. Increase awareness of water-related issues by students, faculty, and staff

2018-19 Priorities and Outcomes

  • Complete 2 landscape renovations.
    • Over 7,000 square feet of turf grass were converted to drought-tolerant landscaping on the east side of Redwood Hall and the west side of Sequoia Hall. Additionally, 11,500 square feet of space was renovated with drought-tolerant plants, trees and crushed granite pathways on the north side of Sequoia Hall.
  • Study potential rainwater capture opportunities for Lindley and Etiwanda streets.
    • An Urban Planning class worked with a Geology professor to determine four feasible bioswale locations for rainwater capture and groundwater recharge on campus. 
  • Pilot smart water metering devices.
    • Smart metering devices are being piloted on five different campus water meters. These devices provide flow data on an hourly basis which can be viewed online, and are also capable of sending leak detection alerts.
  • Examine other opportunities for water reuse including capture of condensate from campus HVAC system.
    • The storage and purification of HVAC condensate was determined to be cost prohibitive, alternatively this water can be collected and piped directly to landscaped areas to reduce irrigation needs. This will be further investigated next year. Additionally, the campus is looking into using blowdown water from its cooling towers for irrigation, and will be including this in an RFP for its cooling tower water treatment contract.

Other Highlights

  • CSUN has replaced over 6,000 linear feet of the Heating Hot Water pipe, which will significantly reduce the daily leak rate.
  • A grant was received from the Metropolitan Water District to study the impacts of hydrogels and compost applications on the water needs of turf grass.

2019-20 Priorities

  • Sub-meter five campus buildings for water and integrate into the Energy Information System.
  • Complete three landscape renovations and include water capture/retention features in each renovation.
  • Pilot water reuse opportunities through the use of HVAC condensate and cooling tower blowdown water.
