Environmental Engineering
Pleasant Mount Welding, Inc.'s Environmental Equipment Division can provide Sequencing Batch Reactors from the design and engineering to the fabrication of the tanks.
Headed by David Klepadlo, P.E., who in 1985 designed the first SBR on the East Coast for the Elmhurst Township Sewer Authority, Elmhurst, PA., winning an Environmental Protection Agency’s, Innovative & Alternative Technology Award for Energy Savings at the Wastewater Treatment Plant (WWTP). Complementing this design with the numerous technological improvements over the past 30 years, PMWI’s SBRs provides state of the art, proven modern wastewater treatment for municipal, commercial and industrial wastewater flows.
PMWI’s systems come complete with fabricated structural steel tankage, blowers, controls, pumps and any additional equipment required to meet your specific treatment requirements. PMWI’s modular systems are prefabricated to allow for ease of installation based on your specific treatment and site requirements.

PMWI custom designs each SBR based on the customer’s requirements for treatment. These SBRs provide an economical wastewater treatment system, reducing energy requirements and the necessity of the addition of chemicals over conventional treatment systems. With their capabilities of nitrogen and phosphorous removals they are ideal for building new or retrofitting older communities WWTPs for complying with the Chesapeake Bay Biological Removal Requirements.
SBR Case Studies - Success Stories
Case #1: Success Story
Wastewater Treatment Plant SBR Retrofit
Greenfield Township Sewer Authority (GTSA) WWTP in Pennsylvania
By installing an SBR and eliminating final clarifiers with return and waste sludge equipment, the GTSA saved over $2 million in project construction costs.
The upgraded PMWI SBR wastewater treatment system allows the plant to handle storm flows while meeting the State's stringent effluent requirements for ammonia and phosphorus.
Case #2: Success Story
New Wastewater Treatment Plant SBR Installation
Benton-Nicholson Joint Sewer Authority (BNJSA) WWTP in Pennsylvania
This facility was monitored for two years to evaluate compliance with the total nitrogen discharge limits set by the Chesapeake Bay Biological Nutrient Removal requirements. It met or exceeded those limits without any chemical addition.
The BNJSA saved over $1 million by not having to construct clarifiers and related equipment.
Case #3: Success Story
Wastewater Treatment Plant Rehabilitation
Hartford Township Wastewater Treatment Plant in Pennsylvania
The Hartford Township's existing Wastewater Treatment Facility is in the process of being completely rehabilitated to function using modern SBR technology from Pleasant Mount Welding, Inc.
This rehabilitation will eliminate the existing Extended Air Activated Sludge WWTP which cannot meet the new Chesapeake Bay nutrient removal requirements on its own. It will be replaced with a new PMWI SBR capable of total Nitrogen and Phosphorus removal.
