Drainage routes from the Dawn Homes development in Fairlie have been changed in response to concerns by the community and environmental regulator.
We have reported over recent weeks about potentially harmful mud and sediment which has been distributed into the Clyde, with photo and video footage of the problem emerging online.
SEPA have called upon Dawn Homes to resolve the repeated pollution problems from their site, after initially being given until 23 December to resolve these issues.
Fairlie Community Council say they have concerns that the sediment has been going into the river and into the Clyde, affecting the marine life ecosystem.
The main problem is that not all of the run-off had been directed to the SUDs pond - a sustainable drainage system pond next to the housing site specifically to deal with surface water drainage discharges from flash flooding.
An element of run off which should have been discharging to the pond was in fact directed in another direction, and discharging into the Keppenburn and onwards to the Clyde, resulting in a public outcry. 
The drainage routes have now been changed and all of the run-off should be entering the pond, say SEPA.
In addition, the environment protection agency have recommended a number of improvements to the situation including an additional uphill drainage ditch to prevent clean water from entering the site and being contaminated and then requiring to be treated. 
SEPA say that there is a need to better manage the run-off from the area where the houses are currently being built, and have given the developer a number of instructions including modifications to the SUDs pond.
The environmental watchdog stated: "There is a need to better manage the run-off from the area where the houses are currently being built. Currently the run-off flows over and scours out the bare earth; SEPA have instructed Dawn Homes to direct the water to flow across stone to reduce the amount of solids carried by the run-off to the pond and reduce the burden on the treatment system.
"It has been agreed that the bare earth bankings will be 'hydroseeded' - a technique where seed and mulch are mixed and applied by spraying the mixture on to the ground in the form a thick paste, preventing wash off in all but the heaviest rainfall events, and should encourage rapid germination and growth."
It has also been agreed that regular SEPA inspections of the burn and the discharge from the pond will be made, and 'appropriate action taken as necessary'.
Dawn Homes told the 'News' last week that work is ongoing, and will continue until the matter is resolved to SEPA’s satisfaction.
