Sustainability Through Comprehensive

Water Management

Water: Georgia Tech Vision

• Protect the health of the river

• Supply all non-potable demands with harvested sources

• Water is the organizing principle of the landscape

• Set the future standard for water strategies for the campus

• Demonstrable water systems and innovation

Comprehensive Approach to Sustainability “Georgia Tech as a Living Learning Laboratory”

• Education:Learning in the Classroom

• Research:Discovery in the Laboratory

• Campus:Practice in Managing our Campus

Education• Technologically appropriate

learning spaces• Research neighborhoods to

promote inter-disciplinary learning• Open spaces for recreation

Ecology• Green buildings• Native vegetation systems• Reduce impervious surface• Environmental Stewardship• Sustainability

Economy• Effective use of Physical and • Fiscal Resources• Historic Districts

Campus Master Plan

Campus Historic Preservation Master Plan

Landscape Master PlanKey Concepts:• Ecological Landscape• Human LandscapeGoals:

Develop integrated, ecologically-based landscape and open space systems (storm water management).Enhance living, working and learning environment.Unify the campus with a distinct sense of place.

Increase tree canopy,replace aging trees

Create an Eco-Commons (80 acres)Implement ecological performance requirements of 50% reduction of storm water runoff

Cistern Master Plan

Clough Commons Cistern: - 1.4M gallon cistern capacity- 28 day supply for irrigation - 28 day supply for toilet flushing - 30% reduction in stormwater

• Promote campus sustainability: – Rainwater harvesting – Reduce stormwater runoff, which contributes to City of Atlanta combined sewer – Create visible campus amenities that functionally contribute to stormwater

management

• Exceed newly adopted City of Atlanta stormwater regulations

Phase 1 - Construction

Provides 44,500 Cubic Feet (332,000 Gal)of Stormwater Infiltration Volume•Over 9.5 times the City of Atlanta requirements.•Provides storage for future development •Provides flow reductions for projects with insufficient land area to meet city requirements (campus-wide approach)

1.4m Gallon Cistern • water for toilet flushing, • irrigation for approximately 13

Fountain • manages stormwater for 22.5 ac

Toilet Flushing (11MG)

Infiltration (43 MG)

• Translates to over $140,000 savings for the City in annual treatment cost by reducing unbilled stormwater in the combined system

• Reducing stormwater contributions to the City’s combined sewer extends benefit to a community that is fighting to reduce sewer spills to the streams (under EPA consent decree)

Investment Strategy (the long view)

• Comprehensive Campus-wide Approach vs. Project-by-Project Basis

Probable Costs of 25 year Build-out Without Stormwater Master Plan Irrigation $3.3 M Domestic water/sewer $14.1 M Cistern/Detention $10.9 M

$28.3 M With Stormwater Management Plan Irrigation $0 Domestic water/sewer $11.9 M Irrig./Stormwater Cisterns $9.8 M Clean Water Cisterns $5.3 M Infiltration & Raingardens $1.4 M

$28.4 M Assumptions:

• 4% inflation rate, 4% discount rate • Domestic water & sewer in future buildings ONLY

• Cistern/Detentions to meet City requirements

City Requires Volume reduction = 0.2 MG Rate reduction volume = 2.2 MG

Master Plan Provides Volume reduction = 1.9 MG Rate reduction volume = 2.6 MG
