The repeated failure of the Tories to implement rules to create “sponge cities” has led to much more visible sewage pollution, more flooding and increasing instances of water being cut off for householders and businesses, they say.

He spoke as the institute published a comprehensive report at Westminster, which calls for the next government to order an independent investigation into water companies, who stand accused of widespread pollution and profiteering, and the regulators, who have failed to robustly control the privatised industry.

Sponge cities are urban zones with multiple areas of greenery, trees, ponds, soakaways, pocket parks and permeable paving to allow water to drain away.
