Phosphate calculator

A bespoke nutrient calculator for the River Lambourn Special Area of Conservation (SAC) has been developed and is available below.

• The  West Berkshire Lambourn Nutrient Budget Calculator [4MB]  Excel spreadsheet
• West Berkshire Lambourn Calculator Guidance [2MB]  for the calculation of a nutrient budget

Note: If you submitted a planning application before Tuesday 13 August 2024, you may wish to rerun the phosphate budget calculations using this calculator if you have a planning application pending a decision.

When submitting the nutrient calculator you will also need to provide evidence that you have received permission for connection to Thames Water systems and which precise WwTW you have applied to connect to.
