미국에서 가장 큰 상·하수시설 중 하나인 워싱턴 수도권 위생 위원회(WSSC)는 LMK Technologies의 인프라 보수 솔루션 2개를 승인했다. LMK Technologies는 하수관로 측면을 갱생하기 위한 트렌치리스(trenchless) 공법 전문업체이다.

LMK의 ‘Insignia™’ 엔드씰(End Seals)과 ‘LMT™(Lined Main Tap)’ 새들은 WSSC의 재료평가위원회(MEC)에 의해 평가됐으며, 180만 명이 거주하는 메릴랜드주 몽고메리 및 프린스 조지 마을에 적용이 승인됐다.

 

 

 

The Washington Suburban Sanitary Commission (WSSC), one of the largest water and wastewater utilities in the U.S., has approved two infrastructure repair solutions from LMK Technologies, a specialist in trenchless methods to renew lateral sewer infrastructure, for use in the Commission's sewer systems.

 

LMK's Insignia™ End Seals and LMT™ (Lined Main Tap) Saddle were evaluated by the WSSC's Materials Evaluation Committee (MEC) and approved for applications in Maryland's Montgomery and Prince George's counties, a region representing 1.8 million people.

 

Since 1993, LMK Technologies has developed trenchless CIPP and sewer rehabilitation technologies. The LMT Saddle is designed to connect lateral pipes to mainline liners and mainline pipes that have not yet been rehabilitated. It is compatible with a variety of lining materials including polyethylene pipe commonly used in fold & form liners and pipe bursting, cured-in-place liners, and PVC folded liners.

 

The Insignia End Seal Sleeve was developed by LMK to ensure seamless and uniform water-tight seals at the end of rehabilitated pipe lining at the manhole penetrations. When used in conjunction with mainline CIPP lining, the Insignia gasket forms a watertight seal in the annular space between the liner and the host pipe because CIPP resins do not bond to the host pipe. Without the compression gasket, water will track behind the liner and re-enter the collection system.
