Groundwork in the garden in Småland Sweden

It is heavy and a lot of work to repair the garden after they renewed the sewer in our garden in Oktober last year. They destroyed the lane (grass) and the driveway. But worse of all, we have a lot of clay and stones in our garden. I didn't know there was clay, till now it was only sandy acid soil. So I assume it came from a lower level.

What a mess: in the middle the new tree room sewer well

At the same time it is a very warm and wet winter, so a got some extra ponds in my garden. Also in the area they have been digging. On that places the water won't go down but keeps on the surface. That's why we try to dig in the ground to open the soil for drainage. We also try to equalize the ground so we can sow grass again in spring. But that is a very heavy job, it will take some time to fix it (we are not the youngest people anymore😉).
Next weeks we will go on with this project. Till now it has been the warmest winter since a long time. When it stays like that we can sow grass as soon as possible. Around the sewer wells we will create a flower border to cover the wells. They are awful to see (not only as a garden lover) so we started to higher up. Maybe we can cover them in some way.
