Utilities & Mobile Metro Water Dumaguete

Apparently, Metro Dumaguete Water (formerly the Dumaguete Water District) is going to invest 524 million in improvements to their infrastructure in the next 5 years.
The problem with that is that we're talking about a company with around 35,000 customers, most of whom pay the minimum charge of 200 peso a month for their water supply.
Now hopefully there's going to be an agency that follows these investments meticulously (which seems doubtful), because these investments will inevitably lead to a major increase of the minimum charge to their customers.
Obviously, major investments are very much needed for a company that doesn't get paid for more than 40% of the water it pumps (system losses, aka leaks).
However, a company with yearly revenue that doesn't exceed 100m p.a. (by my estimate) can hardly afford such investments without raising their revenue substantially, as in raising it by 50% at least.
There's at least three reasons to be upset about this.
a) the City is to blame for causing the situation with the bad leaks (lack of maintenance) prior to the takeover by MDW in 2021
b) We're talking about a life necessity here, and a 50% increase in cost will be devastating for poor people
c) 40% production losses are environmentally very very bad indeed. Despite the devastating rainfall at times from passing storms, our area suffers increasing periods of draught and accompanying drops in groundwater levels.

All in all, while hoping for the best outcome, I fear that's not going to be the case.
