Hello all,
I could use some help and critiquing of my pond design, I have been reading a lot and doing a lot or research. I want to thank you all as I have already learned a ton from this forum. I will hopefully be starting the project in a few weeks. Due to budget constraints this will be a small diy project. I do have a few supplies left over from other home improvement projects (i.e. plumbing, concrete & mortar). I don't want to cut corners just cost. Also, I already have an air pump and a Danner 950gph pump.
I am planning a semi formal 18" deep, 5'x8', kidney bean shaped goldfish pond with flagstone edging and a short waterfall. Due to legal restrictions in my area I can only build an 18" deep pond, going deeper requires a permit. If I do get a permit I can only go to 24", past that I would need a fence around the pond. I don't want a fence around it and I am not worried about having a shallow pond - so 18" deep it is. Luckily this is Northern California and it doesn’t get that cold.
The pond liner will be 10'x15' 45mil EPDM with underlayment. I chose the EPDM because it is durable and has a 25-year warranty. I will not be rocking the inside of the pond nor will it have steps/ledge around the perimeter. I will dig the sides at a 20 degree angle to prevent collapse. Only the back side of the pond will have a step, this will house a tetrapond in-pond skimmer and some aquatic plants/flowers. The waterfall will be either a Home Depot spillway or tetrapond spillway. For filtration purposes I am leaning towards the tetrapond spillway with bioballs or matala filter sponges.
I think that covers most of it.
Here are a few questions I have…
1)How high should the edge of the pond liner be compared to the grade of the surrounding surfaces? I am planning 2" as my yard is very flat.
2)What is the best method to secure the liner? I am planning on pouring a small concrete ledge around the perimeter, folding the liner over it, partially back filling the adding mortar to secure the liner and edging.
