Fiberglass wells are used to clean and flush the sewer system, as well as to monitor the system functioning.
Design and principle of operation
Structurally, a standard well consists of a chamber (well enclosure), discharge pipes fitted into the enclosure, a ladder (if required) and a fiberglass cover. Both linear (installed on straight sections of the route) and rotary wells (installed in places where the route changes direction) are produced. Production of wells of various configurations according to customer drawings is optionally available.
Prior to the installation of a well, all excavation arrangements should be performed - excavation, dewatering, fixing the tank with stainless anchor bolts to the concrete slab to prevent floating up under groundwater pressure. In the case of high groundwater and weak soil, a concrete ring should be cast around the bottom of the well. A vent pipe can also be installed for additional well ventilation. More detailed description of the well installation process is provided in the operation manual.
Service maintenance of wells
The wells maintenance should be carried out at least once every few years, if suspended solids are accumulated at the well bottom. In this case, it is necessary to clean the well walls from dirt, then check operability of its all moving parts (for example, the valve).
