Install new foul primary settlement tank at the eastern extremity of the “known to be serviceable” system. Install pump chamber which will pump settled effluent to the dosing syphon of existing plant, discharging into renovated existing filter beds & ultimately discharged into the Pond System. Depth of primary tank would be approx. 5m deep with an inlet some 2m below existing ground level affording gravity connections into the primary tank. Rising main from pumped effluent would be shallow & avoid deep excavations likely to encounter existing foundations & services.
