O29 Litwornia West Essex Highlands Water Report 82225

Page 4 This issue unaddressed, is reason alone to reject the application since the applicant’s consultants provide no answers. SEWER PROVISIONS Sewer water volume originates from water utilized. The sewer authorities in New Jersy all assume what goes into a facility comes out. The exceptions to this are systems that evaporate like watering lawns and evaporative condensors used in HVAC systems. Using RSIS factors as noted above, the daily sewer volume is estimated at 73,900 gallons per day. Currently there is no place for that daily volume to go that is verified. Secondly, it requires sewer pipe most likely to run across the site where existing sewer pipes run up the mountain. Sewer facilities require pump stations where gravity is not helping convey the flow. Without a plan we cannot envision how this will work. ELECTRIC POWER We estimate 6 mw of power required. The applicant has not shown where that power will be obtained and how it will be routed to the 496 units plus. Possibly a sub-station will be required for this site and plans for its location and architecture are missing. HVAC The application engineering package shows nothing regarding HVAC. We are familiar with what a building with hundreds of units require for HVAC. A likely means used in high rise, Mid -Rises and commercial buildings is a heat pump system. These systems are clean and usually get installed through the walls under windows. Each unit nominally needs 2 tons of heating and cooling with 3-bedroom units requiring 3 tons from a system design perspective. These systems require a heat and cooling source and usually a closed loop water system provides the economical method of handling the heat transfer. Given that there are 496 housing units plus 3 other buildings the load is going to be 1000 to 1500 tons. This dictates one or more cooling towers and heat pumping stations to circulate the necessary cooling/heating water. Cooling towers need to be outside and conveniently located to the buildings. Cooling towers exhaust water vapor visible to human eyes and also present legionella disease risk if not properly managed. NJ has recently enacted legislation addressing this health risk and means to mitigate the risk. A cooling tower uses large volumes of water not included in the domestic
