Case study

From deteriorated to protected

One lift station, four documented phases.

  1. Deteriorated lift station interior with corroded piping before rehabilitation

    Initial condition

    Long-term hydrogen sulfide exposure and moisture intrusion had deteriorated the concrete inside a wastewater lift station.

  2. Cleaned and prepared lift station substrate

    Surface preparation

    Under permit-required confined-space entry, surfaces were cleaned and abrasive blasted so repairs would bond.

  3. Concrete profile restored with repair mortar

    Concrete restoration

    Deteriorated concrete was removed to a sound substrate and rebuilt with Tnemec Series 217 MortarCrete.

  4. Protective coating applied with pumps reinstalled

    Protective lining

    A Tnemec Series 454 lining sealed the structure, followed by final inspection, cleanup, and the owner walkthrough.

Frequently asked questions

Serving South Florida

Miami-Dade County, Broward County, Palm Beach County, Monroe County, Collier County, Lee County. Capacity to support projects in additional markets.

Are you the same company as Protank plastic water tanks?

No. Pro-Tank Water Solutions is a South Florida contractor for municipal and industrial water and wastewater infrastructure rehabilitation. We perform reverse osmosis membrane changeouts, concrete restoration, and protective coatings. We do not manufacture or sell plastic storage tanks.

What types of structures do you rehabilitate?

We rehabilitate municipal and industrial water and wastewater structures, including lift stations, wells, and treatment structures exposed to corrosion, chemical attack, and abrasion.

How do you keep confined-space work safe?

All in-structure work follows permit-required confined-space procedures aligned with OSHA 29 CFR 1910.146, including continuous atmospheric monitoring, mechanical ventilation, a dedicated attendant, and retrieval and rescue readiness.

Which repair and coating materials do you use?

On recent projects we restored concrete with Tnemec Series 217 MortarCrete and installed Tnemec Series 454 protective lining. We select materials to match each structure's service conditions and specifications.

Do you replace reverse osmosis membrane elements?

Yes. We perform complete RO membrane changeouts on municipal and industrial treatment trains: removing spent elements, inspecting pressure vessels, installing new elements to the manufacturer's loading requirements, reassembling vessels, and supporting flushing and startup, all under controlled handling and documented QA/QC hold points.

Do you provide documentation at closeout?

Yes. We verify work at inspection hold points throughout the project and deliver QA/QC documentation, complete a punch list, and perform an owner walkthrough at closeout.

What areas do you serve?

We currently serve South Florida, including Miami-Dade, Broward, Palm Beach, Monroe, Collier, and Lee counties, and can support projects in additional markets. Contact us to discuss your location and schedule.

Do you rehabilitate wastewater lift stations in Miami-Dade?

Yes. We restore deteriorated concrete and install protective linings in wastewater lift stations and similar structures throughout South Florida, including Miami-Dade, Broward, and Palm Beach counties, under permit-required confined-space procedures.
