Bensalem Two Million Gallon Composite Elevated Tank About 2005, Aqua Pennsylvania began planning to minimize its dependence on the Bucks County Water and Sewer Authority for water supply in the North Eastern region of their Philadelphia suburban territory. Improvements were made to their Neshaminy Water Treatment plant; their tanks in Bristol were repainted and additional storage was created by building a two million ground storage tank in Croydon. It was also decided to build a 2 MM Composite Elevated Tank in Bensalem, Pennsylvania. Property for this tank was secured at the intersection of the PA Turnpike and Route 1 in Bensalem. Plans were developed by Pennoni Associates of Philadelphia (Chris Walker was their project manager) under the direction of Aqua PA’s project engineer, Brennen Kelly. Bids for the tank were solicited in 2011 from CBI, Caldwell Tanks and Landmark. Caldwell Tanks was the successful bidder and fabrication began in late 2011. Caldwell utilized its fabrication facilities both in Newnan, GA and Louisville, KY to fabricate this tank. Fabrication included the shop cleaning and priming of all fabricated pieces. In the previous five years, Aqua Pennsylvania has utilized Induron’s Permaclean 100, our 100% solids ceramic epoxy tank liner, to protect the interior of 11 new and rehabilitated tanks. All of these tanks were completed on schedule and to the complete satisfaction of Aqua Pennsylvania. Each was put back into service after rigorous water quality testing. Because of the location and exposure of the Bensalem Composite Elevated Tank, it was recommended by Induron that the exterior finish coat should be our PermaGloss high gloss flourourethane, a coating engineered to provide decades of gloss and color retention. These recommendations were incorporated in the specifications for the tank and were successfully applied by Caldwell’s painting crew. They are included at the end of this white paper. The construction process for CET’s is unique. Once the foundation is poured and the concrete pedestal is constructed, all but the floor and the roof of the steel storage tank is then constructed around the pedestal. Once that is completed, the complete exterior coating system is then applied. Ideally, this would include the application of the logo. In this case however, due to inclement weather delays, the logo was not able to be applied until after the tank was lifted up on the pedestal. This was accomplished on June, 5.2012. .

Bensalem  Two  Million  Gallon  Composite  Elevated  Tank  About  2005,  Aqua  Pennsylvania  began  planning  to  minimize  its  dependence  on  the  Bucks  County  Water  and  Sewer  Authority  for  water  supply  in  the  North  Eastern  region  of  their  Philadelphia  suburban  territory.    Improvements  were  made  to  their  Neshaminy  Water  Treatment  plant;  their  tanks  in  Bristol  were  repainted  and  additional  storage  was  created  by  building  a  two  million  ground  storage  tank  in  Croydon.    It  was  also  decided  to  build  a  2  MM  Composite  Elevated  Tank  in  Bensalem,  Pennsylvania.    Property  for  this  tank  was  secured  at  the  intersection  of  the  PA  Turnpike  and  Route  1  in  Bensalem.    Plans  were  developed  by  Pennoni  Associates  of  Philadelphia  (Chris  Walker  was  their  project  manager)  under  the  direction  of  Aqua  PA’s  project  engineer,  Brennen  Kelly.    Bids  for  the  tank  were  solicited  in  2011  from  CBI,  Caldwell  Tanks  and  Landmark.    Caldwell  Tanks  was  the  successful  bidder  and  fabrication  began  in  late  2011.    Caldwell  utilized  its  fabrication  facilities  both  in  Newnan,  GA  and  Louisville,  KY  to  fabricate  this  tank.    Fabrication  included  the  shop  cleaning  and  priming  of  all  fabricated  pieces.    In  the  previous  five  years,  Aqua  Pennsylvania  has  utilized  Induron’s  Permaclean  100,  our  100%  solids  ceramic  epoxy  tank  liner,  to  protect  the  interior  of  11  new  and  rehabilitated  tanks.    All  of  these  tanks  were  completed  on  schedule  and  to  the  complete  satisfaction  of  Aqua  Pennsylvania.    Each  was  put  back  into  service  after  rigorous  water  quality  testing.    Because  of  the  location  and  exposure  of  the  Bensalem  Composite  Elevated  Tank,  it  was  recommended  by  Induron  that  the  exterior  finish  coat  should  be  our  Perma-­‐Gloss  high  gloss  flourourethane,  a  coating  engineered  to  provide  decades  of  gloss  and  color  retention.    These  recommendations  were  incorporated  in  the  specifications  for  the  tank  and  were  successfully  applied  by  Caldwell’s  painting  crew.    They  are  included  at  the  end  of  this  white  paper.    The  construction  process  for  CET’s  is  unique.    Once  the  foundation  is  poured  and  the  concrete  pedestal  is  constructed,  all  but  the  floor  and  the  roof  of  the  steel  storage  tank  is  then  constructed  around  the  pedestal.    Once  that  is  completed,  the  complete  exterior  coating  system  is  then  applied.    Ideally,  this  would  include  the  application  of  the  logo.    In  this  case  however,  due  to  inclement  weather  delays,  the  logo  was  not  able  to  be  applied  until  after  the  tank  was  lifted  up  on  the  pedestal.    This  was  accomplished  on  June,  5.2012.
