How our WRRF work

Collection System

Helping Water reach its Destination

pumpstations

The collection system conveys wastewater from homes and businesses to one of our WRRF for reclamation of water and other beneficial products through a network of gravity lines and pump stations.

The gravity lines in the network range from 8-72″ in diameter and account for 293 linear miles of pipe. There are over 7,200 manholes that provide access for staff to safely inspect and clean the pipes using state-of-the-art methods and equipment. The system is designed to follow the landscape and utilizes gravity to pull the wastewater through the system.

When it is necessary to lift flow to higher elevation, our 60 pump stations and 51 miles of pressurized force mains ensure continual progression of wastewater. To reduce odors and corrosion in the system, we pretreat water with magnesium hydroxide, a non-hazardous compound, at several of the stations.
