Sewage Treatment Plant installation completed with a new Soakaway system drilled by our team at a very compact site in Cookham Dean, Berkshire. The site also had specimen trees which we endeavoured to protect throughout our works. This client required a new Sewage Treatment Plant installation to replace an old failed Septic Tank and soakaway system at their property. Our drilling team drilled a new soakaway borehole to a depth of 15m below ground level. This new Sewage Treatment Plant discharges to the permeable chalk substrata below the impermeable heavy clay layer.
