Redesign of the waterworks at the Pond

I was never happy with the fountain I had constructed originally when I built the pond. It was more or less a temporary solution.  So last week I decided to redo it.

Digging the path through where the old waterfall was to make what will be a series of 5 waterfalls at the north end of the pool.

The underlying piping infrastructure. Included are a 2″ intake from the pond, a 2″ intake for winter intake from surface water flowing down the south side of the property, a line to three 3/4′ output pipes to spray water back into the pond, a 3”drain for winter water input from the field above the pond, an electrical line from the pump motor leading to an outdoor plugin above the pond, and a water input line to supply evaporative loss from the pond when the two upper storage tanks from winter rains run out. .

The pipes are all covered now and concrete dams are built. Today some final stone placement is left to do before the cascade through the 5 pools for the water entry to the pond is finished. The orange level is to try to keep the lips of each pool horizontal.

The spillway outlet for the pond originally ran out the south end of the pond and this work is on the North end. Now it remains to remove the rocks from the old spillway, install a 4 inch  underground drain, and backfill the trench and lower pumping pond.
