| If operated in conjunction with a coppiced willow tertiary treatment system, this would remove the need to dump sewage sludge into Tramore Bay. |
| The sludge generated from backwashing the filters is sent to a spent washwater tank for recirculation through the facility to minimize waste. |

| Many areas have no waste water treatment plants at all, with sludge and sewage disposal going directly in to the ocean. |
| Even our fruits and vegetables get contaminated by these pathogens through exposure to tainted fertilizers and sewage sludge. |
| The rate of sludge generation in septic tanks is around 0.05 cubic yards every year for an individual. |
