A plan for a massive solar farm is facing an objection over fears toilet waste could pollute local waterways.

The Environment Agency (EA) said it had concerns about temporary toilets installed during the construction of the 80ha (200 acre) solar farm at Seaham Grange in Ryhope, near Sunderland.

It said the company behind the scheme, Elements Green Renewables, should resubmit the application with details of how “foul effluent will be disposed of”.

The company said it had informed the EA the toilets would not be connected to the water drainage system and would be managed by a licensed contractor.
