Stuck behind a River Mease nutrient condition?
The River Mease, across the Leicestershire, Derbyshire and Staffordshire borders, is a phosphorus catchment with a long-standing nutrient management plan affecting new development.
If your site drains to River Mease SAC, the planning authority can't grant permission until you've shown the scheme is nutrient neutral — that it won't add phosphorus to a catchment that's already overloaded. NutrientMonkey gets you the number: build the assessment on screen, watch your budget in kg/year update as you go, and export the planning-ready report when it's right.
Which nutrient applies here
The Mease is assessed for phosphorus, which threatens its protected spined loach, bullhead and otter populations. That matters, because the methodology and the credits differ by nutrient — and neighbouring catchments often differ. NutrientMonkey flags the River Mease catchment for phosphorus and locks the tool to match, so the assessment is right from the start.
How the River Mease calculator works
- Pick River Mease from the catchment list — it's pre-flagged for phosphorus.
- Enter the dwellings & waste water — occupancy, water use (125 or 110 l/p/d plus NE's allowance) and the drainage route (septic, package plant or mains permit).
- Add land use & SuDS — current vs future land cover and any sustainable drainage, with editable export coefficients for the Leicestershire, Derbyshire & Staffordshire catchment values.
- Export when ready — a branded, planning-ready PDF with the budget in kg/year and every input documented.
Honest about what it is
This is a nutrient-methodology assessment built to support your River Mease planning application — fast, clear and ready to discuss with your case officer. The official Natural England catchment calculator remains the statutory tool, and your figures should reproduce in it; the report states this plainly. Want it handled end to end? That's what we're here for.
Frequently asked questions
Which nutrient applies in the River Mease SAC catchment?
The Mease is assessed for phosphorus, which threatens its protected spined loach, bullhead and otter populations. A compliant scheme has to be neutral for phosphorus. NutrientMonkey locks the nutrient toggle to match the River Mease catchment automatically, so you can't pick the wrong one.
Is the River Mease calculator free to use?
Yes — selecting the catchment, entering your dwellings and watching the budget update in kg/year is completely free. You only pay £79 +VAT (£94.80 inc VAT) to export the planning-ready PDF report.
How is the River Mease nutrient budget worked out?
It follows Natural England's published nutrient-budget methodology — waste water, current and future land use, SuDS, then the final budget with the ×1.2 (20%) precautionary buffer. For new homes the waste-water term does most of the work and is computed exactly.
Is this the official Natural England calculator?
No — it's a fast, planning-support assessment that implements NE's methodology, and the report says so. The official NE catchment calculator remains the statutory tool, and your figures should reproduce in it.
