Temporary attenuation tanks and a temporary ditch on the Wainhomes site do not appear to have alleviated surface water run off from the site at all.

Recall that Wainhomes excuse for not putting in the permanent attenuation tanks on this site (before 6 the homes which are now occupied and which the planning inspector said must be put in before ANY homes were occupied) was that they are planning to put in different tanks to accommodate other planning applications they will put in at some point in the future and which may or may not get permission.
What a nightmare this small village is suffering still.
