Earlier this week, the water company was ordered to spend £30.5m on improvements after investigations by industry watchdog Ofwat.
SEW warned in its annual report this week that it needed to secure fresh financing to stay afloat after taking a £55m hit from outages over the winter.
The water supplier to around 2.3 million customers in the south east of England said it was in discussions with lenders to agree a new loan facility.
SEW has been under intense scrutiny since November, when 24,000 customers lost water supply or pressure in the Tunbridge Wells area.
Customers were then advised to boil their water before consumption for a nine-day period after supply returned.
Weeks later, about 30,000 households in Kent and Sussex faced days of supply issues, which bosses blamed on freezing temperatures and Storm Goretti.
The company announced its chair had departed and its chief executive would also leave following the earlier failures.
Paul Sparrow, another Tunbridge Wells resident, told the BBC: “It’s hard to know what to say. We’ve had years of underinvestment.”
