19th Avenue Water/Wastewater/Reclaimed Water Pipelines

South Hillsborough County

Description

Hillsborough County is embarking on an important pipeline improvement program to benefit South Hillsborough County neighborhoods. The 19th Avenue Water/Wastewater/Reclaimed Water Pipelines program in South Hillsborough County consists of three projects to help maintain the capacity of the area’s drinking water and its wastewater collection system to meet increased demand. It also adds reclaimed water distribution systems, as well as 21 new fire hydrants on 19th Avenue between US 41 and I-75. Project details are as followed:

  • Water Line
    • To be placed along the South side of 19th Avenue from just west of US 41 to west of I-75. One mile of existing 10-inch and 8-inch drinking water pipes will be replaced with a new 24-inch water pipe, and approximately 1.8 miles of a new water pipes will be installed.
  • Wastewater
    • To be placed along the north side of 19th Avenue from west of US 41 to west of I-75 and for approximately one mile south, parallel to I-75. Nearly 3 miles of existing wastewater pipe will be replaced with a new larger 24-inch pipe, and 2,700 feet of existing 16-inch pipe will be replaced with a new larger 36-inch pipe. Connections will be provided for new wastewater pipes along 30th Street, 24th Street, 12th Street and US 41.
  • Reclaimed Water
    • To be placed along the north side of 19th Avenue from west of US 41 to west of I-75, and on the west side of 12th Street from 19th Avenue to US 41. Approximately 2.7 miles of new 30-inch reclaimed water pipe and nearly a mile of new 20-inch reclaimed water pipe will be installed along the corridor. Connections will be available for Harbour Isles to access the new reclaimed water main. Connection points will also be provided for any new reclaimed water mains at 30th Street, and US 41 at both 12th Street and 19th Avenue.

What to Expect

Before Construction

  • Hillsborough County selected a design-build construction method for this project, which will save time and money while minimizing public inconvenience
  • The design engineer and contractor will closely collaborate on all aspects of the project to ensure the best construction solutions and the least community impact
  • Before construction begins, crews will be surveying along the project limits on19th Avenue between I-75 and just west of US 41; on 12th Street between 19th Avenue and US 41; and for short distances along US 41 north and south of 19th Avenue
  • During the surveying and investigation of geotechnical conditions and environmental impacts, there may be necessary lane closures. For the safety of the workers, pedestrians and other motorists, please observe all traffic control measures

During Construction

  • Construction will generally take place on weekdays between 7 a.m. and 5 p.m., although some construction work at night and weekends will be necessary.
  • Access to residences and businesses will be maintained throughout construction.
  • Single lane closures will be needed. During lane closures, flaggers will direct motorists through the work zone in a single lane. For the safety of the workers, pedestrians and other motorists, please observe all traffic control measures.
  • If any water service interruption occurs, instructions for a precautionary boil water notice will be issued.
  • Most construction will take place within the right of way; however, at times it may be necessary to work on private property with prior approval.
  • All areas affected by construction will be restored

Cost & Funding

Because the three pipeline projects are along the same road, and in an effort to minimize construction time and any resulting inconveniences to the public, the projects were combined into one design-build contract. The total cost of the three pipeline projects is $20.8 million. The projects are being funded through the Water Enterprise’s Capital Improvement Program.

Timeline

The County plans to begin installing the pipelines in the summer of 2017. Construction is anticipated to be complete in spring 2018.
