February is a great time to celebrate Engineers and all the staff that work in this industry. Mark your calendar, February 18-24, 2018 is Engineers Week. Did you know - The celebration of National Engineers Week was started in 1951 by the National Society of Professional Engineers in conjunction with President George Washington's Birthday? President Washington is considered as the nation's first engineer, notably for his survey work. Check out Discover Engineers Week website (http://www.discovere.org/our-programs/engineers-week) for more information and resources. This is a great opportunity to visit a school or career day and introduce students to the world of engineering.  

The Arizona Chapter is beginning 2018 with a bang. We are getting ready for our 2-5 year Strategic Planning meeting in Prescott later this month. All of your comments from our Chapter Survey will be considered as we initiate our plans to grow our chapter and still meet your individual needs. These plans will include opportunities for education, professional growth, sustainability and networking with peers. A Northern Branch Luncheon is scheduled for February 22nd in Prescott at the Prescott Conference Center. Please register on the Chapter Website. http://arizona.apwa.net/EventDetails/13648

Corona de Tucson Water Reclamation Facility Disinfection and Service Water

Mesa, AZ

Information from Award Submittal

Agency: Pima County

Primary Contractor: Mortenson Construction

Primary Consultant: CH2M Hill

The addition of disinfection and service water to the Corona de Tucson Water Reclamation Facility required careful scheduling and planning to avoid any disruption to the fully operational plant. All construction was scheduled during low-flow, off-peak hours. The intent of the project was to enhance and upgrade the effluent treatment process and provide additional re-use water for site needs.

Budget Management
Adhering to the budget established by Pima County was crucial. The County was very clear that they wanted to simplify operations of the plant and keep performance and safety at the highest possible level. The chlorine contact basin (CCB) was originally scheduled to be pre-cast but due to cost/schedule requirements, the team was able to construct a cast-in-place basin, which ultimately saved the project 3 weeks’ time and $30,000!

Schedule Management
The seven-month schedule was very aggressive, and it was critical that the new parshall flume be operational by November 1, 2016. The team had to complete the parshall flume by this date because Pima County was required to provide accurate readings of their effluent discharge to be in compliance with Arizona Department of Environmental Quality (ADEQ) standards.

Pima County’s mission is to protect the public health, safety, and environment by providing quality service, environmental stewardship and renewable resources. The team’s goal was to utilize the talent of exceptional people, expertise and ingenuity as a foundation for assisting Pima County with this objective. Together, they collaborated to provide a manageable and predictable procurement process for construction, provide advice on cost, schedule, constructability reviews and value engineering studies early on in the project in an effort to mitigate project costs.

Environmental Considerations
Reclaimed water is a vital, locally generated, renewable resource and a key component in Pima County’s available water resources. Its usage aids in mitigating demand on potable water systems, sustaining groundwater levels and preserving green infrastructure throughout the community. It also plays a key role in environmental enhancement, such as riparian habitat restoration projects. Reclaimed water produced from the Corona de Tucson Water Reclamation Facility is a drought-proof alternative water supply that generally grows along with potable water use.

In an effort to maximize recharge and groundwater storage, Pima County looks to recharge reclaimed water from sub-regional facilities, where possible. Corona de Tucson, the only sub-regional WRF with a groundwater storage permit, has served as a proving ground, enabling the department to enhance operational efficiency and increase recharge credits.

Air Quality Control
The team followed strict air quality control/dust control measures during demolition activities as well as construction activities. The continual use of water (provided by a local hydrant) was utilized to control dust migration, which helped reduce pollutants during construction activity.

Stormwater Management
In today’s environmentally-conscious world, the team understands the importance of Stormwater Pollution Prevention Planning (SWPPP). Mortenson has worked with state and local agencies throughout the country to develop stormwater management plans and best management practices tailored specifically to each project.

For the Corona de Tucson WRF project, management of the SWPPP was carried as an on-going topic in bi-weekly internal staff meetings and Owner meetings in order to assure that all potential discharges were protected against properly at all times. Pima County’s environmental team conducted weekly inspections to ensure compliance.

Community Relations
The intent of the project was to provide the public with an improved wastewater reclamation facility that can efficiently handle the needs of the county’s residents. Based on the 2015 average monthly influent flow of 0.295 MGD, the Corona de Tucson WRF currently serves approximately 3,700 people. The addition of the disinfection and service water facility at the plant is a significant enhancement to the community because it improves the quality of life and safety for Pima County residents. The new plant is a zero-discharge facility, which processes all effluent on-site where it is recharged into the local groundwater aquifer.

Unusual Accomplishments
In Pima County’s past experiences at another facility, their parshall flumes had to be reconstructed due to slope and inaccurate readings, which led to re-work and schedule impacts. Therefore, the parshall flume on this project had to be installed perfectly and with the right amount of slope. The team was able to install the parshall flume successfully on the first attempt and without any rework needing to be done. Careful coordination between all team members and trusted trade partners allowed the entire team to accomplish this noteworthy achievement.

The new parshall flume was considered the most crucial aspect of the project. The accuracy of the installation had to be errorfree to ensure discharge flow readings were in compliance with ADEQ standards. Significant planning and coordination with the entire project team was necessary to confirm existing conditions, which helped identify any problems prior to installation of the flume.
