Marshalls Civils & Drainage can custom design a combined sewer chamber to match your wastewater treatment and sewer needs and depending upon the size of the sewer and flow specifications, there are a number of options available from one-piece chambers to flat pack arrangements which will not only reduce the congestion but also offer the advantages of being made offsite which can reduce installation times and costs.
