August Breakfast Meeting

Date:  Thursday, August 24th @ 7:15 AM, * Presentation Begins at 7:30 AM.

LOCATION:

Carollo Engineering, Inc. 4600 East Washington Street, Suite 500, Phoenix, Arizona, 85034 (MAP)

Parking: There are several visitor parking spaces on the first floor of the parking garage (just north of the building, between the building and the American Family Insurance Building). If the gate is open you can also park on the roof of the parking garage.

Building Access: The main doors to the building are locked until 8:00AM, a security guard is generally at the entrance and will let you in, just say you are going to Carollo for the EWRI breakfast meeting. Inside take the elevator to the 5th floor (the door to the stairs is generally locked on the 5th floor). Follow the signs for the EWRI meeting.

SPEAKER:

Puneet Khatavkar

Puneet received his Bachelor’s degree in Civil Engineering from the Maharashtra Institute of Technology, Pune University, India (now known as ‘Savitribai Phule Pune University’) with a gold medal for ‘Excellence in Academic Performance’ and a Master’s (M.S) degree in Civil, Environmental and Sustainable Engineering from Arizona State University in Fall 2015. He is currently pursuing his Ph.D. in Civil, Environmental and Sustainable Engineering at Arizona State University with a specialization in Hydrosystems Engineeering under the guidance of his advisor Dr. Larry Mays. His research interests include systems approach for water resources, optimization of design for stormwater and water treatment and distribution systems, soil and groundwater remediation, flood control systems, hydraulic structures, and hydrological modelling. Puneet actively participates in various activities of the ASU chapter of Engineers without Borders (EWB) and is currently working on a project for construction of percolation tanks for poor farmers in India. He is also volunteering for a EWB local project aimed at uplifting the standard of living and creating economic opportunities for the Navajo people at Shonto, Arizona.

TOPIC:

Model for the Real-time Operation of Water Distribution Systems under Limited Electrical Energy Input

A new methodology for the real-time operation of water distribution systems under critical conditions of limited electrical energy due to emergencies such as extreme drought conditions, electric grid failure, and other severe conditions related to natural conditions is presented. The basic objective of optimizing the operations of a water distribution system under limited availability of energy is to attempt to satisfy the required levels of demand at various locations while meeting pressure requirements of the system and maintaining an optimal pumping schedule. The approach adopted here is to interface an optimization procedure (genetic algorithm) with a simulator (EPANET) in the framework of an optimal control problem to determine the real-time optimal operation of a water distribution system under limited electrical input. The genetic algorithm searches over pump operation in combination with maximizing the demands that can be satisfied with limited energy input. The interfacing of the simulator and the genetic algorithm has been accomplished within the framework of MATLAB.

The Arizona ASCE/ASHE 2017 Conference is coming up on September 15th. EWRI has lined up speakers for an all-day track at this Conference. The track covers a wide range of topics related to stormwater, water, wastewater, groundwater, and environmental topics in Arizona. We have 15 speakers that are going to do 10-15 minute presentations on this wide variety of topics with a 50 minute questions and answers/open panel discussion at the end of the day. Use the links below to be a sponsor or register for this event!

The Phoenix Branch of ASCE is hosting the “Hydraulic Design of Culverts Workshop” on August 29th. This will be taught by Dennis Richards P.E., D.WRE, F.EWRI, F.ASCE. This is a great and affordable opportunity to learn about the hydraulics of culverts from an expert. Please see the Phoenix Branch page for more information.

Committee’s Mission:

“Provide an open forum for discussing technical water resource issues within Arizona.”

Objectives of the EWRI include:

  • Conducting technical education programs on water resource topics
  • Sponsoring activities that serve the need of water resource professionals
  • Furthering public understanding of the field of water resources, hydraulics, and environmental engineering
  • Coordinating local water resource related functions with other related organizations
  • Review and comment on state and local legislation related to water resource issues

The Committee meets monthly to hear presentations and discuss technical water resource issues, studies, and projects. Field trips are occasionally offered to allow participants to witness firsthand how local water resource issues and challenges are being addressed.

Accomplishments
Past Committee Activities:

  • Monthly technical presentations on current water resource topics
  • Field trips to local water resource projects
  • Coordination of technical sessions at AzSCE conferences
  • Assisting other local water resource organizations with their functions and workshops
  • Serving as local host in 1999 for the American Society of Civil Engineers (ASCE) Water Resources Planning and Management Division’s 26th Annual Conference, held in Tempe
  • Assisting with local ASCE sponsored workshops on Urban Stormwater Management, HECRAS, etc.

Bylaws
The group’s bylaws were adopted in 1995 and are available from the Committee’s Secretary or can be downloaded here (14 KB, PDF).
They address the following:

  • Officers: Chairman, Vice Chair, Secretary, and Past Chairman.
  • Membership: Any subscribing member of the AzSCE who submits a written request for membership shall be considered a member.
  • Annual Business Meeting: Held on or before October 31.

Membership
Because the EWRI is sanctioned by the ASCE, committee membership requires membership in ASCE. However, non-ASCE members are welcome to attend committee meetings and events. There are no dues, other than those normally paid by members of the ASCE. To request an ASCE membership application, please contact the ASCE at (800) 548-2723 or online at www.asce.org.
