If your sewage treatment plant is well maintained and serviced then it should not smell. If your plant is giving off an odour, even if it's intermittent, then it could be the symptom of a problem. Please give us a call to book a visit to diagnose the issue and get it repaired. Ignoring symptoms such as bad smells could lead to bigger issues and more costly repairs.
Can a Marsh Treatment Plant serve more than one property?
Yes, Marsh Treatment Plants are designed for both residential and commercial properties and there are also systems designed to serve more than one property. For residential properties, we carry out a calculation for multiple domestic dwellings to establish the size of the treatment plant required to serve all of the properties. For commercial properties, we need to understand what the property is used for to identify the most suitable treatment plant system.
