Water and Waste

 

Waste water Purification Plant: Ladignac le Long

dégrilleur red

This plant came into service in 2013 and treats all waste water in the village. Waste water is mixed with rain water since the drains are interconnected. Pumps enable the plant to deal with the waste from the campsite, village hall and the village housing estate.


It provides waste treatment for the equivalent of 700 inhabitants.


Should there be very heavy rain, an overflow beside the church allows excess surface water to flow directly into the black stream without passing through the treatment plant.


Waste water passes through an automated grill system which separates out solid matter (mainly paper) in the waste water.

 

The waste water then runs through a narrow channel where a meter measures the rate of outflow.

Afterwards the effluent collects in a tank (7m3)called the flush, covered by a grill. When this body of water is full, a syphon starts which sends the water down into a basin planted with reeds on a bed of sand, the waste water being filtered by the sand. There are three receptors like this side by side and the operator decides into which basin the water should flow
