Detailed description
Design and operating concept

Effluent flow regulation in the rainwater treatment system.

Operating concept:

EXCEEDING THE MAXIMUM WATER LEVEL > OUTPUT BRANCH PIPE > BACKUP EFFLUENT SYSTEMS

The standard manhole consists of a chamber (manhole housing), output branch pipes built into the housing, a ladder (if required) and a fibreglass lid. The manholes are manufactured as linear (to be installed in direct sections of the route) and rotary manholes (to be installed in places where the direction of the route changes). It is possible to produce manholes of different configurations according to the customer's drawings.

Installation

Prior the installation of manholes, an excavation pit should be arranged: excavation, water level reduction, fixing of the tank with stainless anchor bolts to the concrete slab to prevent floating up under the groundwater pressure. In the case of high groundwater and weak soil, a concrete ring should be cast around the bottom of the manhole. It is also possible to install a ventilation pipe for additional ventilation of the manhole. For more details on the manhole installation technology, you can refer to the operating manual.

Maintenance

The manholes should be maintained at least once every few years if suspended solids have accumulated at the bottom. In this case, clean the walls of the manholes from dirt, then lubricate all moving parts with petroleum jelly (vaseline), e.g. the valve, and make a performance test.
