CHESHIRE POOL HISTORY Pool built in 2003 – invested $4.7 million to date Pool itself is successful – events, recreation, etc. 1.5 million+ user-days to date Serves all swimmers: learners – competitors - seniors Generates $600,000 in annual revenue Bubble problematical Many failures, tears – snow, wind, handling Total in-service time only 70% Most recent February 2013 – snow – insurance paid Bubble presently a total loss We can use insurance for any structure Will insurance company cover another bubble? Issue now is what enclosure we need
PRIMARY NEEDS • Affordable Construction cost o Operating cost (energy) o • Recreational swimming Water safety training o True outdoor swimming in summer o All season capability as approved by voters o • Competitive swimming Adequate spectator capacity o • Proven application in this climate • Minimum down time
INVESTIGATION STATUS About 1,500 hours by members, consultants Three finalists Redesigned bubble Tension membrane structure Polycarbonate panel structure
REDESIGNED BUBBLE Other bubbles did not collapse Design for deflation Eliminate damage factors Strengthen attachments Soften protrusions Reconfigure lighting Deflate when weather strikes Evacuate pool Store equipment safely Reinflate with minor repairs
TENSION MEMBRANE Widely used for swimming Olympics, community pools Durable permanent frame Steel or aluminum Stretched membrane Teflon/fiberglass Insulated to R-35 Raise/remove sides Skylights, vent panels possible
POLYCARBONATE STRUCTURE Popular upscale structure Water parks Natatoriums Greenhouse look Permanent aluminum frame Insulated structural panels Transparent Durable Insulated glass walls

ALTERNATIVES CONSIDERED Summer Only Pool Winterize in Fall – no provision for competition or community use Seasonal Structure Present air supported structure (bubble) Bubble With Modifications Bubble With Relocated Operations Building Permanent Structure Tension membrane Conventional Construction Polycarbonate /aluminum Other Add Competitive Pool to Cheshire High School Split Pool : Part Seasonal/Part Enclosed Moveable Panels Close Pool Facility Menu
ALSO CONSIDERED Trends in Northeast Summer only converted to year-round Bubbles being reevaluated Greater concern about extreme weather Winterization problem Menu
WINTERIZATION PROBLEM Pool designed for year-round use Drains Piping Deck fittings Security High wall Required Winter cover Modify deck, drains, high wall Secure building, pool Startup/shutdown procedure Cost One-time $300,000 - $500,000 Annual $100,000 - $200,000 Menu
NOT VIABLE - 8 Summer only pool Present bubble Bubble with relocated building Conventional construction Split pool Moveable panels Close pool facility Competitive pool at CHS Menu
REDESIGNED BUBBLE Construction cost $250,000 Operation $ annual Pro True swimming outdoors Most structure already in place No missed operation Can change operating procedures to protect Con Annual downtime Highest energy cost Fragile, poor life Airlock is awkward Risk to support building Collapse usually catastrophic Worst energy usage Concern about insurability Menu
TENSION MEMBRANE Construction cost $2 to $3 million Operation $ annual Pro Reparable on site Longer life Excellent energy Excellent openness Shading in summer Many sources Con Not completely outdoors swimming Menu
POLYCARBONATE STRUCTURE Construction cost $5 to $7 million Operation $ annual Pro Reparable on site Longest life Best energy Best for direct sunlight Con Highest construction cost - Few sources Competitors say it’s too bright inside Menu
OPTION: CO-GENERATION Gas Distribution Pipeline Co-generation unit – about 12’ X 6’ Excess Power power Purchase Initial $ 297,000 Agreement Annual savings $ 50,000 Payback 5.9 years Water Electricity heating
