Purchasing for Water Conservation :  Purchasing for Water Conservation November 14, 2007 Presentation by Robert P. Matney NC Division of Purchase & Contract Engineering Section Conservation is a Necessity:  Conservation is a Necessity Currently Many Counties in NC are in Extreme to Severe Drought Conditions Raleigh has 98 days of supply remaining (Dec 10th) Durham has about 7 weeks of drinking water left in two primary reservoirs (Dec 6th) Options to Increase Water Supply Are Limited and Expensive Sustainable Purchasing Goals:  Sustainable Purchasing Goals Provide Products that Reduce Consumption Minimize Environmental Impact of Water Consumed Current Mandates:  Current Mandates Senate Bill 668 – State Law 2007-546 allows only the purchase of Water Efficient Products for Existing Buildings and New Construction for state facilities. The Governor strongly encourages and promotes the products to implement an immediate reduction in water consumption. State Law 2007-546 - Existing Buildings:  State Law 2007-546 - Existing Buildings Installation of aerators in sink faucets that reduce the flow of water to a minimum 0.5 g.p.m. Installation of shower heads that reduce the flow of water to a minimum 1.5 g.p.m. Resetting hot water heaters to 120 degrees; Training of staff to monitor the use of irrigation systems and to base the use of the system on the moisture content of the soil, Either the elimination of potable water for irrigation or the reduction of water consumption in the building by twenty percent (20%) based on water consumption for the 2002‑2003 fiscal year. State Law 2007-546 - New Construction:  State Law 2007-546 - New Construction Water systems shall be designed and constructed to use a minimum of 20% less potable water than the indoor water use baseline calculated for the building after meeting the fixture performance requirements required by the 2006 North Carolina Plumbing Code. Outdoor potable water or harvested groundwater consumption shall be reduced by a minimum 50% over that consumed by conventional means through water use efficient landscape materials and irrigation strategies, including water reuse and recycling. Water and Energy Saving Components for Immediate Use:  Water and Energy Saving Components for Immediate Use Low flow 0.5 gpm faucet spray nozzles Low flow 1.5 gpm showerheads Currently soliciting quotes or bids for an interim term contract for these basic items. A permanent term contract will be available in a few months to provide low flow and efficient water use with a wider selection and thread options. Lavatory Faucets:  Lavatory Faucets Low flow 0.5 gpm faucet SPRAY nozzle Laminar Stream – minimum 1.5 gpm (hospitals) Aerated - minimum 1.5 gpm (typically kitchens) Spray - minimum 0.5 gpm (hand wash) - Vandal-proof Lavatory Faucet Water Savings :  Lavatory Faucet Water Savings Typical lavatory faucet may have a flow rate of 2.2 gpm to 2.8 gpm, or greater if an older building. A faucet flow rate of 0.5 gpm would be a minimum of a 77% reduction. Showerhead Water Savings:  Showerhead Water Savings Low flow 1.5 gpm showerheads Typical shower heads may have a flow rate of 2.2 gpm to 4.0 gpm, or greater if an older building. A faucet flow rate of 1.5 gpm would be a minimum 40% to 60% reduction New state wide contracts :  New state wide contracts Water efficient fixtures and plumbing accessories are intended for early an February, 2008 start date. New P&C website. Purchase & Contract Services:  Purchase & Contract Services State Wide Term Contracts Convenience Term Contracts Open Market Solicitations E-Quotes Purchase & Contract Complete Array of Services Available :  Purchase & Contract Complete Array of Services Available Statewide Term Contracts Open Market Solicitations Advertisement of Bids via the Internet E-Procurement Oversight & Support Vendor Training & Outreach Vendor Registration Qualified Products List Compliance & Purchasing Education Inspection & Customer Service Standard Specifications Future Water Components :  Future Water Components Low flow urinals Waterless urinals Dual flush toilets Metering faucets Water flow controls for faucets Water flow controls for irrigation systems Commodities that Support Long Term Efficient Water Use :  Commodities that Support Long Term Efficient Water Use Foam Hand Soaps Ice Makers Disinfectants and Dilution control Green Cleaners Foam Hand Soaps:  Foam Hand Soaps Foamed (prelathered) dilute liquid Some products do not require preweting hands Antibacterial, lotion and basic types Green certified products available Ice Makers :  Ice Makers Bid evaluations include cost of energy and water use Utility efficient cost (EEC) formula: UEC = Bid Price + Cost of Energy + Cost of Water UEC = P + ( C x [((E x ER) + (W x WR))] x F x 365 x 5 ) Where: P = Bid Price C = Minimum harvest rate for 24 hour ice making period F = 2/3 operation factor for 5 years E = KWH per lb of ice (ARI certification ratings for unit bid indicates KWH per 100 lb. of ice ÷ 100) ER = $0.08/KWH (EXAMPLE ONLY – may be increased to reflect utilities at time of bid.) W = Gallon per lb of ice (ARI certification ratings for unit bid indicates Gal per 100 lb. of ice ÷ 100) WR = $0.00683 per gallon of potable water (EXAMPLE ONLY – may be increased to reflect utilities at time of bid.) Contract will only include air cooled appliances Disinfectants and Dilution Control:  Disinfectants and Dilution Control Products provided are EPA registered are specific to various levels of infection control and pathogens. Dilution control equipment will be available to allow effective infection control while preventing excessive toxicity, and increased cost for the end use solution. Vendors are to provide training for proper in use of disinfectants and operation of equipment. Green Cleaners:  Green Cleaners Industrial and Institutional Cleaners, GS-37 Standard Evaluation criteria includes: Toxic Compounds, Carcinogens and Reproductive Toxins, Skin and Eye Irritation, Skin Sensitization, Combustibility, Photochemical Smog, Tropospheric Ozone Production, & Indoor Air Quality, Toxicity to Aquatic Life, Aquatic Biodegradability, Eutrophication, Packaging, Concentrates, Fragrances, Prohibited Ingredients, User Training, Animal Testing, and Labeling Requirements   LEEDs Points:  LEEDs Points LEED™ (Leadership in Energy and Environmental Design) framework for assessing building performance, green building design and construction, sustainable resource use. LEED™ initiative developed by the U.S. Green Building Council (USGBC) Building Codes has been considered for adoption in North Carolina. Flow restrictors can help earn one or two LEED points in the category Materials and Resources, Resource Reuse (Credit type 3) for a 20% or 30% reduction of water use beyond the level set for plumbing fixtures by the Energy Policy Act of 1992. Simple Low Cost Residential Water & Energy Saver :  Simple Low Cost Residential Water & Energy Saver Pre-slit foam pipe insulation permits faster delivery of hot water to avoid wasting water while it heats up. Also controls condensation and reduces plumbing noise. Communications:  Communications Regularly broadcast user and vendor surveys for commodities purchased Need user requirements for products needed on term contract May need users for advisory panels Need users to communicate successes and suggestions P&C Commitment:  P&C Commitment Water Reduction Energy Efficiency Customer Service Strategic Water Technology Conference:  Strategic Water Technology Conference December 14, 2007
