Lift Station Rehabilitation Project No. 1

Lift Station #17, located in right-of-way between 200 W Monroe St and W Madison St, Port Isabel, is near completion. Start-up of new pump station is in progress. District has abandoned existing pump station located next to new structure. Final cleanup, security fence, and site restoration will get done to complete work at this site.
Lift Station #35, located at 350 Port Road, is pending enclosure for disconnect to complete electrical
work. Start-up for new lift station can then proceed as well as abandoning existing lift station located next to new structure. Work should be complete by November 2023.
For Lift Station #4, located at 33120 Washington Ave in Laguna Heights, work pending completion includes abandoning existing wet well & pump station, installing two submersible pumps & diesel back-up pump, piping & valves. Electrical work is in progress; however, control panel is not scheduled for delivery until January 2024. Estimated date of completion at this location is February 21, 2024. 
Contract Time for substantial completion is May 3, 2023, and Contractor is at-risk of being assessed liquidated damages.














Water Treatment Plant #1 Improvements (Port Isabel)

Construction is progressing to replace the existing conventional sand filters with a 5 million Gallons per Day (MGD) microfiltration treatment plant including, but not limited to, the following improvements:
•    New raw water intake structure and pumps,
•    Install a new microfiltration (MF) treatment system housed in a new facility,
•    Equalization basin for the MF system,
•    New high service pump station,
•    Chemical storage, containment, pumps, and piping systems,
•    Yard piping and associated valves, structures, and appurtenances,
•    Associated electrical, instrumentation, and Supervisory Control and Data Acquisition (SCADA) improvements,
•    Associated mechanical, structural, architectural, and plumbing improvements, and
•    1.5 million gallon (MG) pre-stressed concrete ground storage tank (GST).

On August 23, 2023, Laguna Madre Water District Board of Directors ratified Change Order #2 with ariaFILTRA, formerly known as Pall Water, to modify equipment that will be able to receive surface water diversions from either the Rio Grande or Laguna Madre Bay. The following equipment changes are required to be prepared for a Port Isabel Seawater Desalination Treatment Facility: Feed Pumps, Reverse Feed (RF) Pumps, Feed System instrumentation and valves, Feed Strainers, RF instrumentation and valves, Microfiltration Rack instrumentation and valves, Clean-in-Place (CIP) circulation and drain pump and strainer, CIP circulation valves and instruments; & Neutralization system pump, valves and instrumentation. Resubmittals are under review for approval as these modifications are being done prior to equipment being released for fabrication. District anticipates a Notice to Fabricate (NTF) to be issued around November 1, 2023. Equipment will be ready to ship 45 weeks after NTF. Installation completion is 16 – 20 weeks after equipment delivery, and commissioning will be complete 12 weeks after installation is complete. Electrical equipment being provided by the General Contractor has long lead times that may affect this schedule.

Yard piping and related equipment to be provided by the General Contractor, separate from equipment being provided by ariaFILTRA, is being reviewed and modified as needed to accommodate a future seawater application. Drilled piers have been installed for the Microfiltration Building, Equalization Tank, and Neutralization Tank. Geopiers will be used for proposed Ground Storage Tank. Contractor has submitted Metal Building Shop Drawings, Precast Wire Wound Prestressed Concrete Tank, Electrical, Chlorine Dioxide Generator, et. al. for review and approval by Freese and Nichols, Inc. Upcoming work includes setting the piers for Ground Storage Tank and forming the foundation for MF Building. Final completion of construction is scheduled for June 20, 2025.   

Proposed Elevated Storage Tank #6 (600,000 gallons) & Remaining Water System Improvements
On September 14, 2023, Texas Water Development Board (TWDB) approved a Drinking Water State Revolving Fund Financial Commitment of $12,980,000 Loan to Laguna Madre Water District. Project request includes construction funding for a backup generator at Water Treatment Plant #1; 600,000-gallon Elevated Storage Tank #6 to replace existing 300,000-gallon Tank #1 in Port Isabel; Raw Water Transfer Pump Station Upgrade to increase capacity of Rio Grande surface water diversions from Laguna Vista (Reservoir #3) to Port Isabel (Reservoir #1); and Water Treatment Plant #2 High Service Pump Station upgrades in Laguna Vista. Date of Closing is Thursday, November 9, 2023. Design is scheduled for completion by January 12, 2024. Construction completion is scheduled for November 5, 2025.

Long Island Village

SWG Engineering, LLC is preparing plan drawings, contract documents, and technical specifications to upgrade water and sewer system within Long Island Village that will be accepted by Laguna Madre Water District upon completion of construction. Water distribution system improvements include 23,110 feet (ft) of 8” PVC pipe and 1,004 residential service connections from new meter to residence. Wastewater collection system improvements include two new lift stations, 1,730 ft of 6” force main, 1,600 ft of 10” force main, 23,488 of 8” sanitary sewer line upgrades, 141 manholes, and 1,004 residential service connections from cleanout to residence. The District and SWG Engineering held a 30% Design workshop on October 10, 2023. Project is scheduled to be advertised for construction in January 2024, then award construction contract on March 13, 2024. Notice to Proceed with construction is scheduled for April 9, 2024. Construction contract time is 540 days, resulting in completion by October 15, 2025.
