Update on drainage

Upon our return to Oba chan chi's during my Spring break holidays we were confronted with watercress that had happily grown all along the drainage line that we had dug on our previous visit.

Our little helper was eager to get her new garden gloves dirty!

Once we  pulled away the watercress  and dug a drainage line that was straight, rather than  the original curved one, we were ready to lay the gravel and PVC piping.

              

 What great progress my treasures had made in one day!

A concrete U drain was set in place beside the flow of water and then the seams were sealed together with water resistant concrete.

This is the side view from the opposite side.

We used the concrete lids to the U drain to make a retaining wall.

Front view of the retaining wall with a bit of the concrete chiseled away to allow for the water to flow.

We laid the PVC pipe down just to see if it was sitting correctly against the retaining wall before making any adjustments.

While its not pictured here,  gravel was laid under the PVC pipe for support, as we are planning on covering the pipe over, but just wanted to wait and see if the water was flowing where it should be. 

So we achieved a lot on this particular day. We also developed a back ache from digging and lifting heavy concrete! So the onsen was a welcoming treat come the evening.
