Inadequate road drainage and blocked gullies

Although we have had the property 61 Ellacombe Road for six years, this year following heavy rainfall we have had our property flooded out with surface and sewage water twice in 6 weeks. The water is coming down Windsor Road and hitting our property at force which is on the corner of Ellacombe Road and Berachah Road. We have ourselves taken action to stop this happening. But the problem also needs addressing in the area as we are not the only affected property. I have spoken to South west water who have referred me to the highways as after inspection they have found that the road gullies were blocked. Apart from needing clearing more regularly as this is a vulnerable spot to heavy rain being at a lower level I feel that more road gullies at this point would help similar to a number that have been put down Windsor road.
