Septic Tank and PTP upgrade: opportunity mapping & modelling
What the buyer wrote
Natural England are exploring the use of replacing inefficient septic tanks and package treatment plants (PTPs) with PTPs that have a higher treatment efficiency for phosphorus and nitrogen to improve water quality in up to 27 catchments.

For each catchment, we require estimates of the following: Scale of opportunity: The scale of opportunity (in units) of upgrading inefficient septic tanks and PTPs in each catchment. This will need to be mapped using GI software. Nutrient reduction: The potential nutrient reduction achieved (in kg/TP and kg/TN) for phosphorus and/or nitrogen depending on the NN catchment from replacing inef…
