Liners & Coatings Save Pump Station Concrete
Corrosion of unprotected concrete
Romtec Utilities offers PVC and fiberglass liners and epoxy coatings for the interior surfaces of concrete wet wells and vaults in our wastewater pump stations. These treatments help prevent damage to the concrete from gasses and liquids that may be present in the sewage. The most common concern is hydrogen sulfide gas emitted from municipal wastewater and the sulfuric acid that forms through a bacterially mediated process. A description of the process that causes degradation of concrete from sewage gas is copied from Wikipedia at the end of this article. Read more
Valve assembly location – 3 options makes a difference
Valve assemblies in Romtec Utilities pump stations
Romtec Utilities pumping systems include the complete valve assembly between the pumps and force main. The basic valve assembly includes a check valve and a plug (isolation) valve in the discharge line from each pump. But that’s about it for basics, because each pump station has unique requirements for the valves and where they are located. Depending on various factors, the valve assembly can be located within the wet well, within a separate underground vault or above ground within an enclosure or right out in the open.
In-well valves – For submersible pump stations, reduced cost is an important factor in locating the valve assembly inside the wet well. Less pipe, fewer fittings and no underground vault or above ground enclosure are required, thus reducing cost.
Sufficient space inside the wet well can be a factor; the valves have to fit in the vertical pipe riser. The pre-assembled Read more
Gimme Shelter – pump station control shelters and buildings
Romtec pump station control shelters and buildings
Consider including a shelter or building in your pumping system design
Many lift stations need a weather/shade shelter or building to protect the control panel and to provide convenience and safety for operators.
Romtec Utilities partners with our sister company, Romtec, Inc. for design, supply and installation of steel shelters and solid concrete buildings to protect pump station controls. Together, the two companies provide a one-stop shopping approach to building a system complete with lift station and protective structure.
STEEL SHELTER - A Romtec powder coated steel shelter provides cooling shade for the pump station control panel and can be the most cost effective way to reduce the operating temperature inside the panel enclosure. It also gives weather protection to components anytime the enclosure must be opened. Operators don’t mind the shelter from blistering summer heat and winter precipitation either. Read more
Fiberglass Advantages
12' dia. prefabricated fiberglass wastewater pump station
Romtec Utilities’ complete sewage pumping systems are available with wet wells and vaults of either fiberglass or concrete. The high-quality Xerxes fiberglass underground tanks are delivered to the job site fully assembled and ready for pipe and pump installation. Here are some of the advantages of fiberglass:
- Complete one-piece structures require no field assembly. Pre-assembled fiberglass wet wells are ready to receive influent and discharge pipes, submersible or dry pit pumps and liquid level sensing devices.
- One-piece fiberglass vessels up to 12 feet diameter and 40 feet long can be shipped to any project location.
- Tanks have no joints to be sealed, so there is no potential for groundwater incursion.
- Unique rib design makes wet wells more resistant to uplift the deeper the tank is placed underground. Read more
Distribution warehouse gets submersible sewage pump station
Distribution warehouse pump station collects combined sanitary sewer, storm runoff and, potentially, water from the building's fire suppression sprinklers.
Pumping system handles combined sanitary sewer, stormwater and potential fire suppression system water.
Romtec Utilities recently supplied a sewage lift station to the new 750,000 square foot Ferguson Enterprises Regional Distribution Center built on the site of a former US Navy facility in Stockton, Calif. Thomas Graham Civil Design Group was the project engineer and pm2i was general contractor.
Romtec supplied all structural, mechanical, electrical andtelemetry systems in the station, which features a 6’ dia. pre-cast concrete wet well to collect the combined sanitary sewer and stormwater runoff, as well as potential drainage from the building’s fire suppression sprinkler system. Also included in the complete system are a pre-assembled valve vault and all ductile piping, U.L. listed electrical controls and SCADA, and two ITT Flygt submersible pumps that discharge through a 4” dia. force main to the municipal gravity sewer.
Pump station odor & corrosion control with chemical feed system
Romtec Utilities chemical feed system for wastewater pump station
Sewage pumping systems are frequently fitted with chemical feed for odor and corrosion control plus worker safety.
Wastewater collection systems, including pump stations, can be subject to the build-up of hydrogen sulfide gas (H2S), frequently the source of unpleasant odor and a serious cause for concern due to potential corrosion of concrete exposed to the gas. Operator safety is an even more serious matter, since breathing high concentrations of H2S is potentially lethal.
Romtec Utilities supplies odor/corrosion control chemical feed systems in its complete pre-engineered wastewater pump stations. The chemical feed system allows various chemicals to be introduced into the pump station’s wet well or into the force main. Siemens BIOXIDE® solution is the chemical most frequently specified by Romtec Utilities for control of odor, corrosion and safety problems associated with hydrogen sulfide in wastewater collection systems.

Flow metering – an important pump station addition
Complete flow metering vault with sensor, and readout/transmitter
Consider flow metering for accurate measurement – Pumping systems are frequently required to measure the volume of fluid being pumped over a period of time. This is often the case if a subdivision or industrial site is billed by the municipal sewer agency for the amount of wastewater it discharges to the sewage treatment plant.
Calculating the flow – An easy and inexpensive way to get a reasonable estimate of the volume of wastewater being pumped is to “calculate the flow.” This is done by multiplying the volume of water pumped with each pump start by the number of pump starts over a period of time. The resulting number, the total volume pumped during the period, is useful for estimating purposes.
Flow metering – Flow metering may be necessary for proving the discharge volume. Romtec Utilities supplies a number of flow metering systems from leading manufacturers as part of our complete wastewater submersible pump stations. Read more
