SEWERLOCK designs locks that are independent of existing manhole frames and covers and that can be set to release overflow from the sanitary sewer. SEWERLOCK is designed to keep people out, prevent dumping and theft, and provide environmental safety. Based in the USA, we ship worldwide.
SEWERLOCK systems manage and maintain sanitary sewer flow and eliminate SSOs. The subring mounts under the existing cast iron frame and cover in any size or shape manhole without out modifying the existing structure including the existing cover. The SANITARY SEWERLOCK elimates storm water inflow and can be set to eliminate sewage overflows. The inner cover prevents falls in cases where the street-level manhole cover has been stolen or removed. The existing manhole cover can be attached to the locking unit to prevent theft. Each device locks out unauthorized entry and can be ordered with odor control which features an air test hole so you can measure the air before the lid is removed.
The device is made of stainless steel and does not corrode, providing a lifetime solution to securing the manhole. Locks can be ordered to match the keys of your other utilities for your convenience. There are no moving parts that can seize up. Lightweight and easy to install, you can install the device in less than 15 minutes.
