A design-build delivery for the East Water Treatment Plan Improvements Project is fairly innovative for the City of Boynton Beach. Based on the previous work staff has done with our Climate Action Plan we wanted a holistic framework for evaluating and rating the community, environmental, and economic benefits of this project. Sustainability of construction materials and in-depth public outreach are just some of the many great attributes of this project in achieving the Envision™ certification.

Quick Facts & Statistics

  • The preliminary Envision™ score for the East Water Treatment Plant Design/Build Project is 71%.  Anything greater than 50% is a Platinum Rating, which is the highest score possible.


The City of Boynton Beach Progressive Design/Build project for our East Water Treatment Plant Ion Exchange is to mitigate against potential salt water intrusion, upgrade to high energy efficient pump systems and meet the future water demands in a high density downtown population. In response to our City’s Climate Action Plan, and in alignment with the SE FL Regional Climate Action Plan, we have adopted a risk-based decision support tool for analysis of infrastructure design, water resource management, natural systems management, hazard mitigation and more.  The Envision™ Rating System provides a holistic framework for evaluation.

Implementation Process

The City has a track record of being sustainable by meeting the needs of the present and future residents while balancing environmental stewardship, social responsibility, and economic growth.  The project is being delivered using the progressive design-build method, whereby the design-build team works under a single contract with the City to provide design and construction services. United from the outset of every project, an integrated team readily works to successfully complete a project faster, more cost effectively and with fewer change orders. This is a high-profile project and the City deemed it important to integrate sustainability and public outreach with the progressive design-build approach.  As a result, this project incorporates sustainability assessment using Envision™ as well as project specific outreach.  Envision is a scoring system administered by the Institute for Sustainable Infrastructure which evaluates the sustainability of various types of infrastructure projects with regards to energy, water, waste, transport, landscape, etc.  The points awarded to a project with respect to these categories help communicate the overall sustainability of the project. City staff, in collaboration with the design-build team, assessed the sustainability indicators over the course of the project’s life cycle. Five areas of assessment, each with 7 to 14 separate indicators, addressed Quality of Life, Leadership, Resource Allocation, Natural World and Climate. As we went through the process we were able to evaluate the environmental benefits while assessing the costs/benefits over the projects expected lifecycle.  The metrics provided supported decisions about investment of resources and addressed community and environmental priorities. 

Implementation Timeline

The Notice to Proceed for the Design/Build EWTP project began on April 7, 2015 and staff started working on the Envision™ rating system in September 2014.  Final completion for the Design/Build is scheduled for November 2016 and we expect to receive our Envision™ certification between December 2015 and July 2016.  The Envision™ system looks for some items during construction and those will be submitted as the project progresses.

Implementation Funding

The project is being budgeted through the City of Boynton Beach Utilities Department Capital Improvement Projects (CIP) budget.

Community Benefits

The City continues to demonstrate its leadership in the effort to achieve a sustainable future for its residents. New energy-efficient, high-service pump systems and motors will reduce the overall energy consumption of the water treatment plant and the new infrastructure ensures the protection and adaptation against future sea level rise and associated saltwater intrusion.  By drawing raw water from our Western Wellfield and pumping it east to re-rate the existing East WTP facility to a maximum daily capacity of 24 mgd, the City is assuring water delivery to its citizens to meet future demands, while reducing Greenhouse Gas Emissions (GHGE) and the overall carbon footprint of the water treatment plant.
