The city of Escondido, Calif., had converging challenges. It had too much wastewater and not enough potable water.
A 15-mile pipeline that carries treated wastewater from Escondido to the ocean almost overflowed during storms in 2010. More urgently, the aging pipeline was near capacity, no longer big enough to handle the city's growing needs. The estimated cost of upgrades was between $400 and $500 million.
Meanwhile, like many other cities in Southern California, Escondido needed to rely on imported water to meet its customers’ demands. It is costly and limits the city’s control over its water quality.
"Escondido needed a cost-effective solution that would be practical and not just somebody's dream," said Black & Veatch Program Manager Kevin Davis. "It had to be creative."
The answer: water reuse. Black & Veatch helped the city solve its challenges with a water reuse project that provides a sustainable water supply to the area's avocado and citrus farmers and set the stage for future potable reuse.
