Although the main pipe that goes from Perranporth to the sewage treatment plant by Cligga goes past the front of the house, that is under pressure and isn’t a pipe we can discharge into.
At the moment Silver Spray is a soakaway !
So, as the house is being “upgraded” we’ll be fitting an on-site sewage treatment plant. These treat the toilet waste and to a level where the water meets the rules to be discharged into the groundwater.
This is what the neighbouring properties all have.
Talking to Environmental Drain Services:
- As it’s a treatment plant and not a septic tank the 7m minimum distance from a habitable dwelling rule does not apply.
- You need to be able to, on-going, access the lid to get into it. So you can build decking etc over it, but you can’t stand, drive or put earth over it.
- We should be able to rely on the percolation test / survey done for Ramoth way, as this is just next door. It’d be very unlucky for this to not be indicative of the Silver Spray ground.
