Weatherheads were approached to meet with the owners of five cottages who shared an outdated Septic Tank with a failing Soakaway. The Tank required weekly empties to avoid pollution which was very frustrating and expensive for the home owners who sought a prompt solution. We stepped in and carried out the installation of a Marsh Industries Ensign P25 Sewage Treatment Plant. Whilst carrying out the install the flow from the five dwellings was maintained by our tankering team, which enabled the householders to remain living in their properties throughout the duration of the works. The excessive empties are now no longer required, and this unit will now only require a routine empty to remove the sludge and a routine service visit to keep all the mechanical and electrical components in working condition.
