kokoojaviemäreihin

Kokoojaviemäri, often referred to as a main sewer or collector sewer, is a vital component of a wastewater collection system. It is a large-diameter pipe designed to receive wastewater from multiple smaller lateral sewer lines, which in turn collect sewage from individual buildings or properties. These lateral lines typically connect to the kokoojaviemäri at various points, consolidating the flow.

The primary function of a kokoojaviemäri is to transport significant volumes of wastewater over longer distances, usually towards a wastewater treatment plant or another designated discharge point. Due to the larger volume and flow rate, kokoojaviemärit are often installed with a specific gradient to ensure gravity-driven flow, although pumping stations may be incorporated in flatter terrain or for specific topographical challenges.

The design and material of kokoojaviemärit are crucial for their longevity and effectiveness. Common materials include concrete, ductile iron, and various plastics like PVC and HDPE, chosen based on factors such as pressure requirements, soil conditions, and cost. Regular inspection and maintenance are essential to prevent blockages, leaks, and structural failures, which could lead to environmental pollution and public health risks. The capacity of a kokoojaviemäri is calculated based on the anticipated wastewater generation from the connected area, considering population density and industrial or commercial activities.
