Soakaways on the chalk
Where a drainage field is dug down into clean chalk, the effluent usually soaks away without fuss. The catch is that it travels down quickly too, so anything a septic tank fails to hold back can reach the groundwater with little filtering on the way.
That makes regular emptying especially worthwhile here. Sludge allowed to build up to the outlet pipe will carry over into the soakaway, clogging it and polluting the chalk beneath. If you’re worried about yours, ask us about soakaway maintenance. A tank emptied on time is far less trouble than a soakaway that has to be dug out and rebuilt.
