We finished off connecting the last large drain pipe to the Filtration Module, this being the final last resort overflow connection to the soak-away unit.

Then the next job was to climb inside and apply extra sealant around the clean water section and its joints. It was a tight squeeze but we managed it! Finally, we vacuumed out the slightly dirty water in the bottom of the cabinet to reduce the amount of grit and dirt to avoid fouling up our water pump.
We spent the remaining of the day shovelling all the sandy soil back in and around the cabinet and piled the excess up around it so it can settle down over time.
The last task was to get the lids installed, using stainless steel threaded rods, glued and screwed in various places around the rim and clearance holes in the lid themselves.

The filters and baffles were lowered down inside the module and everything is now ready for the next rain shower, at least off the garage roof, but we can now connect up each section of the guttering (as we complete the slate tiling) and any water will be drained and properly filtered to our water storage tank.
