My name is John and I have a drainage problem. My neighbors here in sunny southern California are not exactly flush with irrigation and drainage experience, so I'm hoping to find some wet-region wisdom here.
In a nutshell, I need to move stormwater from our backyard out to the street (and city storm drain) about 80 feet away. Seems like the least invasive route would be some sort of basin/float pump combo buried in the backyard with a PVC line running out to the curb.
Last year I installed a channel drain across the driveway, in front of our detached garage. Behind the garage, I've got a full width french drain that is also new. Both drains are 4" and terminate (for now) into the backyard about 30 feet apart. In light rain, everything flows to the yard as intended. Once backyard becomes saturated, however, the channel drain backs up and pools against the 18' garage door. Then floods the garage.
My temporary fix has been a $60 submersible pump, below grade at the channel drain's exit. It's barely adequate and also completely manual. Helpful only if I am both home and awake. It's time to sack-up and make things right.
Seeking input, recommendations and words of wisdom on...
Everyone loves pictures, so here's the sort of stuff I'm finding on Amazon (but know nothing about)...

- drywell/basin sizing
- pump type, manufactures and sizing (with reliability, serviceability and value in mind)
- pros & cons of using a single basin/pump for both drains*
- hard lessons you've learned that I might avoid
