PWSA (Pittsburgh Water and Sewage Authority) is the provider for water and sewage services throughout the city of Pittsburgh. I don’t like their rates, but will have to accept them as they are my only options. I don’t use much water. I drink about 2 gallons of water a day. I only need to wash a dish every other day. I don’t need to bathe every day as I will usually be home. All of these things will reduce the amount of water I will use. Still, PWSA’s are expensive.
