Untreated Dialysate and septic tanks

HI

 Does anyone know of a good reference for advice on this? The high salt and sugar content of untreated dialysate causes problems with septic tanks. I did have a good source here www.greendialysis.org but the site seems to have disappeared. There is a chat about it here ‘Poo and Goo’…Dialysis Effluent and the Septic Tank - Home Dialysis Central but it is very focused on Australia. I wondered if anyone knew what advice is given to UK based patients? Many thanks
