Sewage Treatment Plants

This picture gives some idea of the size of the smallest domestic sewage plant. It seems very large from this perspective.
After the installation, when all is tidied away and the unit is working, all that remains visible is the lid which gives access for maintenance and de-sludging.
The installation of this type of plant normally takes about a week from start to finish.
This unit was installed in a corner of the garden. It was soon to be hidden behind a row of shrubs

Positioning of the sewage plant is important. It must be within approximately 30 metres of hardstanding where a desludging tanker can park.

It is also important to remember that shrubs can grow very quickly so a reasonable margin should be left for access to the plant for service and maintenance.
