toxicity of cleaner / steriliser run off

[Fil]

Im planing on moving my brewing off the patio to a distant shed, Utilities are a problem including drainage.. im considering holding a store of cold grey water as a thermal dump for wort chilling, which will be the run of from cleaning with laundry oxy and sterilising with starsan mainly.

cleaning water will be hose fed, brewing water i will lump up there in jerrycans,

this grey water will accumulate beyond my capacity to store it, the easy out the door option will run over a neighbours lawn and garden, the easy short distance solution for me to pump would be close to and drain into my veggie plots...

to hit drains is about 40m..

so would degraded laundry oxy and starsan be a problem for the veggies to drink?

I dont use wvp in great quantities but do use small amounts of bleach to wipe down, i assume both these would not be good for the garden and should not go into the grey water?

How about digging a soak away next to the shed?

A sound thought but in this case not too practical, me? shovel?, that'l be the day
though its not just my idleness in the way , a few tons of poured concrete path then a step up to another paved concrete base for a wooden shed an a 2ft x 10ft strip of lawn, next to a fence seperating the neighbours lawn, then down 3 ft to the vegie plot level.

the path is sloped away, and is the course for natural drainage, but if i drop my drain into it it will flow down into the neighbours yard following the path. thru the gate. i could wait to drain until its raining.. but thats a bit too sneeky for me. and what if the rain pauses while 400l of grey water continues to get pumped out, the neighbour may smell a rat.... If i ask the neighbours permission im sure i will get a 'yes sure', but i dont have confidence that it would be a real honest answer, and fear it would actually cause problems..
