A total of £46,000 was awarded help prevent flooding in five Crawley communities.
Thousands of pounds from a county council fund will be used to clear and make drainage grills safer.
The drainage improvements received support from community groups.
Sue Perry, of Colinsey Road, Broadfield, chairwoman of Talk Broadfield, said £10,000 would be invested into clearing grills in the neighbourhood.
She said some of the grills had not been cleared for more than ten years.
She added assistance from residents or further funding was still needed to stop flooding in Broadfield.
The issue will be discussed at a Talk Broadfield meeting on Thursday (February 13).
Some £14,000 will be invested in Maidenbower after the Maidenbower Park Community Group approved the council’s project for the area.
The funding will go towards clearing and maintain water courses as well as drainage grills.
St Andrew’s Church, Furnace Green, welcomed the £12,000 that will be spent on drainage in their neighbourhood.
Firefighters pumped water from a tunnel linking Furnace Green and Maidenbower following a residents’ petition on Thursday morning (February 6).
Northgate Matters and St Nicholas Church, Worth, saw their neighbourhoods awarded £5,000 each.
The grants came from the council’s Operation Watershed Active Communities Fund. The fund was set-up to help communities prepare for floods and reduce highways or neighbouring land flooding.
