Severn Trent Services to Market Potable Water Filter Designs Directly to North American Municipal Market


Company's TETRA® LP Block(TM) dual parallel underdrain filters are becoming increasingly popular with plant owners for their low headloss, lightweight construction and easy installation.

FORT WASHINGTON, Pa. - Severn Trent Services, a leading global provider of water and wastewater solutions, has begun marketing its line of potable water dual parallel underdrain designs directly to the North American municipal market. The company is now selling its TETRA® LP Block(TM) underdrain filters directly to municipal potable water customers through a manufacturers' representative network. This new arrangement will enable Severn Trent Services to provide direct product sales and maintenance services to customers while maximizing competitive product pricing.

Severn Trent Services had previously marketed its TETRA LP Block through an arrangement with Degremont Technologies-Infilco.

In potable water applications using gravity filters, the filter underdrain is one of the most important components contributing to overall system performance and operation. The TETRA LP blocks are popular with plant owners for their low headloss, lightweight construction and easy installation either as a retrofit or for new filter underdrain applications. The easy-to-assemble TETRA underdrain filters ensure exceptional installation strength, integrity and maintenance-free life with no moving or wearing parts.

The underdrain filters feature the GroutGrip(TM) design, which helps to alleviate the buoyancy inherent in any plastic underdrain installation. Additionally, the wide, low-profile design requires that fewer blocks be installed to cover a filter floor. Therefore, fewer joints and less grout are needed.

Severn Trent Services' TETRA LP Block filter underdrain systems are also an ideal solution for pre-treatment filtration at desalination plants. The system's proven design provides superior distribution for both water and air, separately or concurrently. The blocks are formed covering the floor of the gravity filters, supporting the filter media. Air is distributed evenly across the entire filter bottom area to scour the media and to provide an air lift which, with the water, removes the released solids from the filter. This dual backwash action provides intense washing energy throughout the filter.
