East Carolina University Long-Term Water Efficiency Plan July 30, 2004 Prepared by Rebecca Bizzell Director, Resource Management - Campus Operations Reviewed and approved by Rebecca Bizzell Director, Resource Management - Campus Operations USI Liaison / Water Efficiency Coordinator William Bagnell Director, Facilities Engineering and Architectural Services Ken Kisida Executive Director, Facilities Services - Main Campus David Lancaster Director, Facilities Maintenance - Health Sciences Campus George W. Harrell, PhD Senior Associate Vice Chancellor for Campus Operations East Carolina University Long-Term Water Efficiency Plan A. Commitment [State reasons for developing plan and agency’s commitment to water conservation.] East Carolina University developed this long-term water efficiency plan in response to the following concerns, restrictions, directives, and mandates. East Carolina University recognizes utility conservation, water conservation, water quality management, resource management, and sustainability efforts as the responsibility of the entire University community including faculty, staff, and students. On behalf of the University community, ECU Campus Operations shall continue to initiate, evaluate, and implement water conservation measures as appropriate to support the mission of the University. The University’s Utility Conservation & Awareness Committee shall continue to monitor the University’s efforts and progress. Governor Easley’s August 2002 Executive Order No. 26, Water System Protection, directed all State agencies to discontinue “non-essential” water use until further notice and to develop and implement long term financially feasible conservation measures. Upon completion of a long-term water efficiency plan, a State agency may request that the directive by Executive Order No. 26 be lifted to allow consumption of water for “nonessential” uses. The NC General Assembly October 2002 House Bill 1215 mandated that all State agencies reduce water consumption. In response to recommendations by the Capital Management Subcommittee of the Governor's Efficiency Study Commission, the State Facilities Utility Savings Initiative (USI) was created by the State Energy Office (SEO) in FY02-03 to assist State agencies with lowering their utility costs and to ensure that State agencies have implemented operation and maintenance conservation measures. 07/30/04 Rebecca Bizzell Page 2 of 30 East Carolina University Long-Term Water Efficiency Plan B.

Active building pressure control systems to limit infiltration h. Increased Roof Insulation greater than the Energy Code (Increase from min R15 to R20) i. University wide summer operating hours 07/30/04 Rebecca Bizzell Page 12 of 30 East Carolina University Long-Term Water Efficiency Plan 2. Computerized irrigation system reduces water consumption Grounds Services central control irrigation system, Maxicom, provides irrigation in the most water conscious manner. By using a weather station, Maxicom determines how much water is lost daily and only puts back that much water through irrigation. This system also detects leaks, maximizes run times, and compresses the amount of time it takes to irrigate, making shorter water windows. This system is currently used in various areas surrounding properties on Charles Boulevard including Allied Health complex and Carol Belk building, Blount intramural fields, Grounds Services Complex, ECU Athletic complex, 14th Street properties including Facilities Services warehouse and the Moving Services/Recycling building, and College Hill properties including Jones Residence Hall and Galley dining facility and Todd Dining Hall. Additional areas are being considered for future expansion of the system. Grounds Services utilizes the “Cycle+Soak” option on the irrigation controllers allowing the water to infiltrate at the soil's own pace. In addition, “Rain Cans” are used to stop irrigation systems from running when it is raining on all controllers that are equipped for the device, approximately 75% of the irrigation controllers. FSSP 34-0007, Facilities Services Irrigation Schedule, details Grounds Services irrigation schedule. Grounds Services conducts 95% of required watering in the early morning hours and minimizes the number of days vegetation is irrigated. Grounds Services does not use public water or well water for irrigation on the Health Sciences Campus. The water used for ornamentals and turf irrigation is taken from Laupus Lake, a storm water retention pond located on the Health Sciences Campus grounds. This pond is recharged with each rainfall and does not impact surface or ground water recharge. (John Gill, Assistant Director, Facilities Services – Grounds Services, East Carolina University.) 3. Installation of ground water wells for cooling tower water supplies As discussed in the Strategic Energy Plan completed in August 2003, East Carolina University Facilities Services has been unsuccessful in negotiating sewer credit with Greenville Utilities Commission (GUC) for evaporating potable water in the University’s cooling towers. Realizing that potable water from GUC is not the only viable option, the University investigated water well capacity necessary to support the University’s main chiller plants on both campuses. As such, the University installed three water wells on each campus, for each of the three major area aquifers, Black Creek, Cape Fear, and Pee Dee. These wells are controlled with variable speed drives to maintain a set pressure in the distribution system. They are connected to the University’s building automation system to provide flow and pressure information and to sequence the operation to avoid withdrawing more than 100,000 gallons of water in a 24-hour period from either the Black Creek or Cape Fear aquifers. Water chemistry variations in the various aquifers were evaluated as a design criteria to minimize system problems. The water from this system is used for cooling tower make-up and irrigation as well as for cooling and scrubbing in the University’s medical waste incinerator system. As these wells are not designed nor permitted to be used for potable water, the system is physically separated from the GUC’s supply of potable water. Utilization of this water helps reduce peak demand loads on the GUC system. The current and 07/30/04 Rebecca Bizzell Page 13 of 30 East Carolina University Long-Term Water Efficiency Plan projected use of this resource is seasonal facilitating recovery of the ground water system during low use periods. The conjunctive use of surface and ground water promotes sustainability of the University’s vital water resources. (David Lancaster, Director, Facilities Maintenance – Health Sciences Campus, East Carolina University.) 4. Water Conservation Measures in Boiler Operations Main Campus: Boiler surface blow-off is on an automatic system using conductivity in lieu of continuous blow-off. Main Campus and Health Sciences Campus: All main header steam traps are on an annual replacement schedule to prevent excessive steam use. All secondary systems are on a 5-year replacement schedule and are tested periodically to verify proper operation. Steam Plant bearing water is recovered as make-up water for the Steam Plant’s boilers. (Robert Newell, Supervisor, Facilities Services – Utilities Services Main Campus Steam Plant, East Carolina University.) 5. Water Conservation Measures in Main Campus HVAC Operations During 2003-2004, Facilities Services implemented the campus-wide aqua-track system that allows monitoring water usage, chemical doses, bleed rates, and makeup water at all cooling towers in real time 24 hours a day. All information is charted and reviewed by HVAC personnel at the end of each week to insure that water is being used appropriately. When inappropriate uses of water are reported, a technician is sent to inspect the system. As a result of the real time monitoring, two stuck valves were discovered within days of the problem occurring. A stuck valve would allow water to over flow out of the tower into a drain. A problem such as a stuck valve could result in a cooling tower using in excess of one million gallons of water that was not required in just one month. If the HVAC shop had not been monitoring water usage, the technician would not have found the problems until the water bill had arrived and revealed the large usage. According to the ECU Supervisor, Facilities Services – Utilities Services HVAC, ECU is the only campus in the UNC system that monitors water usage in real time. (Ken Yarnell, Supervisor, Facilities Services – Utilities Services Main Campus HVAC, East Carolina University.) 6. Showerheads in Residence Halls Campus Living replaced all standard showerheads in each of its fifteen Residence Halls with low-flow showerheads. These devices effectively reduce water consumption from greater than 5 gallon per minute/showers to 2.5 gallon per minute/showers as well as reducing energy needed for water heating. (FSSP 30-0005, Water Conservation Measures.) 07/30/04 Rebecca Bizzell Page 14 of 30 East Carolina University Long-Term Water Efficiency Plan 7. Facilities Services Standard Practices addressing water conservation measures ECU Campus Operations – Facilities Services developed FSSP 30-0005, Water Conservation Measures, to outline the University’s financially feasible water conservation measures at three levels of water conservation urgency. a. Normal Conservation Procedures - Normal conservation procedures are continuous and on-going financially feasible water conservation measures implemented by Facilities Services. b. Phase I Conservation Procedures – Facilities Services’ normal conservation procedures are considered adequate unless a more aggressive measure is indicated in the Phase I section. Phase I conservation procedures are more aggressive financially feasible water conservation measures to control water uses by Facilities Services. The Senior Associate Vice Chancellor for Campus Operations or his designee shall authorize implementation and revocation of Phase I water conservation measures per State directives, local situations, etc. c. Phase II Conservation Procedures – Facilities Services’ normal conservation and Phase I procedures are considered adequate unless a critical measure is indicated in Phase II section. Phase II conservation procedures are critical financially feasible water conservation measures to control water uses by Facilities Services. The Senior Associate Vice Chancellor for Campus Operations or his designee shall authorize implementation and revocation of Phase II water conservation measures per State directives, local situations, etc. The University addressed conservation measures for each use of water outlined in the guidance materials developed by the Water System Protection Team. For example, FSSP 30-0005 describes normal conservation procedures for irrigation of lawns and ornamental plants by noting the central control irrigation system. FSSP 34-0007, Facilities Services Irrigation Schedule, details Grounds Services irrigation schedule and the use of storm water for ornamental and grass irrigation at Health Sciences Campus. Other FSSPs are incorporated by reference in Section I – Maintenance Programs. 8. Utility Conservation & Awareness Committee / Conservation Awareness Team The Water Conservation Liaison serves on the University Utility Conservation & Awareness Committee (UC&AC) (formerly known as the Utility Conservation Committee) which functions as the Conservation Awareness Team established at the request of the State Energy Office to implement the outreach and education program designed by the State Energy Office USI Education committee. The UC&AC continues to be involved with conservation efforts including, but not limited to, the following: Developing a hot water curtailment program for restrooms and break areas Developing an individual conservation program supporting the education and promotion of conservation efforts by individuals and departments Below is a list of measures used to reduce air conditioned loads in buildings which reduces the amount of water consumed by cooling towers: Implementing unoccupied setback program 07/30/04 Rebecca Bizzell Page 15 of 30 East Carolina University Long-Term Water Efficiency Plan Implementing shorter operating hours at Joyner Library and reducing lighting in stack areas Distributing peak alert notices and information regarding peak savings to the campus community Using energy saving florescent bulbs in lieu of incandescent light bulbs Modifying Minges doors so that they will not automatically lock open but can be locked open when needed Evaluating the impact that the early August start-up has on utility costs for future planning consideration 07/30/04 Rebecca Bizzell Page 16 of 30 East Carolina University Long-Term Water Efficiency Plan E. Prioritized Conservation Opportunities The following water conservation opportunities were identified based on primary sources of use including, but not limited to, personal water consumption, laboratory consumption, cafeteria use, mechanical consumption, HVAC water use, cleaning use, janitorial use, landscaping consumption, maintenance and contractor use. Three criteria were selected to prioritize the identified water conservation opportunities: amount of water currently used, financial feasibility or affordability, and payback period. Each identified water conservation opportunity was ranked accordingly as high, medium, or low priority. In financial feasibility criteria, high priority indicates low to moderate cost, medium priority indicates moderate to high cost, and low priority indicates not financial feasible. In payback period criteria, high priority indicates immediate payback, medium priority indicates payback in a reasonable amount of time, and low priority indicates payback will not be reached in a reasonable amount of time. The opportunities ranking high in two or more criteria may be selected for immediate consideration based on funding availability. 07/30/04 Rebecca Bizzell Page 17 of 30 East Carolina University Long-Term Water Efficiency Plan Current Water Use # Water Conservation Opportunity 1 Install low-flow shower heads. 2 Install low-flow faucet aerators on hand sinks.

Target Reduction Goal Recognizing water consumption as a controllable expense, the University has aggressively instituted energy management measures from no/low cost efforts to major capital improvements over the past 7 years. As a result, ECU has already realized a majority of the savings potential associated with these measures. In addition, the forecasted increasing enrollment, corresponding increase in University personnel, and the construction of more than a half million square feet of new space and extensive renovation of an additional 200,000 gross square feet afforded by the 2000 bond referendum will significantly increase the University’s total water consumption over the next 5 years although the University has required the design of new and renovated space to include the latest water conservation measures. Since ECU has exhausted the majority of available savings potential associated with current square footage and has significant growth in energy efficient square footage scheduled and funded, the University’s total water consumption will increase even with the support and direction provided through the Governor’s Utility Savings Initiative. 07/30/04 Rebecca Bizzell Page 21 of 30 East Carolina University Long-Term Water Efficiency Plan G.

Medical Pavilion, Quadrangle) on the Health Sciences Campus. 07/30/04 Rebecca Bizzell Page 23 of 30 East Carolina University Long-Term Water Efficiency Plan H. Employee Education and Awareness Program [List steps to implementation and components specific to your program.] The University Utility Conservation & Awareness Committee (UC&AC) supports utility conservation, water conservation, water quality management, resource management, and sustainability efforts by members of University community. The UC&AC also functions as the Conservation Awareness Team established at the request of the State Energy Office to implement the outreach and education program designed by the State Energy Office USI Education committee. With the support of the Chancellor, the UC&AC communicates water conservation information with University community including, but not limited to, water conservation plans, water conservation methods, and water use restrictions. The UC&AC periodically reminds the University community of water conservation efforts and notifies faculty, staff, and students of recurring problems with compliance or any changes in policy. As new water conservation efforts are implemented, the UC&AC communicates these changes to members of the University community. In the event that restrictions, mandates, and directives are issued at the county, city, or State levels, the UC&AC communicates with the University community regarding required water restrictions. With the support of the Chancellor, the UC&AC recommends water conservation measures to the University community for implementation when financially feasible. When financially feasible, the UC&AC shall make posters highlighting water conservation and proper methods of water use and notices highlighting NC laws and regulations on water conservation and sustainability available to members of the University community for posting in areas of water consumption. 07/30/04 Rebecca Bizzell Page 24 of 30 East Carolina University Long-Term Water Efficiency Plan I. Maintenance Program [List steps to implementation and components specific to your program.] 1. Preventive Maintenance Activities Facilities Services routinely performs a broad range of maintenance and operational activities that inherently recognize leaks and malfunctioning equipment, as well as, ensure accurate measuring and reporting of water usage. The following tasks and activities are examples of the broad range of preventive maintenance activities routinely performed by Facilities Services personnel: Task Inspections PM PM PM PM PM Monitoring Shop Buildings HVAC HVAC Steam Plumbing Plumbing Grounds System Rooms/Facility Mechanical Instrumentation Condensate Pumps Fire Suppression Pools Maxicom irrigation system Frequency Qtr Weekly/ Qtr/ Annual Annual Qtr Weekly/ Annual Weekly Daily, on central control computer Description Restroom, Leaks, Stains Leak Checks Flow Calibration Leak Checks Leak Checks Leak Checks Checks leaks, overflow situations Other, misc. irrigation systems Daily, by crews observing sites Check for leaks, blow-out situations, etc. (Wayne Reeves, Assistant Director, Facilities Services – Main Campus Maintenance Engineering, East Carolina University.) 2. Facilities Services Standard Practices ECU Campus Operations – Facilities Services documents and outlines policies, procedures, and aspects of the preventive maintenance program in the Facilities Services Standard Practice series (FSSP) available on the Facilities Services web page www.ecu.edu/facility_serv/ or specifically at Facilities Standard Practice Manuals htttp://www.ecu.edu/facility_serv/fssp/numericalindex.htm . The following FSSPs are incorporated by reference: a. ECU Campus Operations – Facilities Services has developed a series of FSSPs outlining procedures associated with natural disasters. FSSP 23-0001.3, Health Sciences Campus – Water System Outages or Problems, outlines procedures to address water system outages or problems on Health Sciences Campus although the loss of domestic water from Greenville Utilities Commission (GUC) for extended periods of time is unlikely. However, a broken main or contamination of a water source could result in an interruption to the water supply to the Health Sciences Campus. Malfunctions in the GUC system or on the Health Sciences Campus system could result in short-term interruptions or disturbances affecting the domestic water system. 07/30/04 Rebecca Bizzell Page 25 of 30 East Carolina University Long-Term Water Efficiency Plan b. The North Carolina Department of Environment and Natural Resources (NCDENR) performs an annual Sanitation inspection of the University’s buildings. EH&S coordinates pre-inspections and interim sanitation inspections through Facilities Services. These inspections are conducted using the same criteria as the NCDENR inspections. Representatives from Facilities Services, Housekeeping Services, and EH&S conduct these inspections. Where appropriate, representatives from other departments (Athletics, Student Recreational Services, etc.) also participate in inspections of their areas of purview. FSSP 32-0008, NC Department of Environmental & Natural Resources (NCDENR) Sanitation Inspection, outlines responsibilities, procedures for participation in these inspections including preinspections, and methods to address items discovered during a pre-inspection or cited by the inspector. FSSP 35-0006, Preparation for Sanitary Inspections, outlines Housekeeping Services efforts in anticipation of the annual Sanitation inspection. These efforts include aggressive reporting of leaking faucets and valves. c. ECU Campus Operations – Facilities Services has a direct impact on energy conservation through four phases of operations: New Building Construction and Major Renovation; Building Operation; Building Maintenance; and Building System Upgrades. A major focus of these four phases is on projects that have the most energy-saving potential. FSSP 33-4001, Facilities Services Energy Plan, outlines efforts and responsibilities in the different phases. Facilities Services has developed energy operating plans for University facilities including, but not limited to, residence halls, academic and administration buildings, Student Recreation Center. d. East Carolina University has two primary shifts of Housekeepers that have the responsibility to properly clean all campus buildings, both on and off campus sites. In the course of their daily work, Housekeepers routinely view all campus facilities. And in doing so, Housekeepers will discover building discrepancies, including, but not limited to, drains stopped-up, toilets stopped-up, toilets running water, faucets leaking, water fountain not working/not working properly, etc. while performing these routine housekeeping duties and tasks. Any and all building discrepancies or problems shall be properly reported through the ECU work order system. All Housekeepers shall complete a Housekeeper’s Building Report to report these discrepancies/problems as they are found per FSSP 35-0013, Housekeeping Building Reports. e. North Carolina environmental health rules govern the water temperatures in a number of different areas from a number of different points of use. FSSP 33-4001, Water Temperatures Standards, has been developed to set a standard for these hot water temperatures and to apply a monitoring scheme to assure appropriate hot water temperatures are maintained. f. FSSP 33-4013, Sonic Plaza, outlines responsibilities for maintenance, upgrades, and operational procedures associated with the Sonic Plaza. The Sonic Plaza is an architectural element of the Library complex that includes a ground cloud and water wall. 07/30/04 Rebecca Bizzell Page 26 of 30 East Carolina University Long-Term Water Efficiency Plan 3. Construction Standards ECU Campus Operations – Facilities Services is responsible for the operation, maintenance, and renovation of the educational buildings, utilities, and grounds of the ECU campus. Campus Operations requires construction that is complete, durable, easily maintained, energy efficient, and compatible with existing and planned systems. Campus Operations has developed Construction Standards to express the University’s requirements in different construction areas and are intended as a guide for the Design Professional in developing project designs. These Construction Standards are written from the viewpoint of Campus Operations and generally name Facilities Engineering and Architectural Services as the entity representing ECU in administering the design and construction of University facilities. The Construction Standards state that ECU is extremely interested in initiatives in energy management such as sustainable building designs that effect lower operation costs and good stewardship of State funds and natural resources. The Construction Standards explain that the simplest and most effective method of energy conservation is to turn things off when not in use. To this end, spaces with similar occupancy schedules should be grouped together, to the extent possible, on the same HVAC system, to accommodate unoccupied shutdown. The Construction Standards are available on the Facilities Services web page www.ecu.edu/facility_serv/ or specifically at Construction Standards http://www.ecu.edu/facility_serv/Construction%20Standards/TableofContents.htm . 07/30/04 Rebecca Bizzell Page 27 of 30 East Carolina University Long-Term Water Efficiency Plan J.

When aggressive conservation measures are required, essential water uses may be curtailed or drastically reduced. 07/30/04 Rebecca Bizzell Page 29 of 30 East Carolina University Long-Term Water Efficiency Plan L. Continuous Improvement [Explain your plan for continuous improvement.] For FY04-05, the University Utility Conservation & Awareness Committee (UC&AC) shall continue to meet quarterly to evaluate progress on specified actions, communicate progress, and designate new targets, as necessary. At the beginning of each subsequent fiscal year, the UC&AC will re-evaluate water conservation efforts at ECU, analyze progress, and identify new target areas for water efficiency. The UC&AC will also review drought stages for Pitt County and maintain awareness of drought status and any city, county, or State ordinance changes that impact water use. 07/30/04 Rebecca Bizzell Page 30 of 30
