A young architect has an idea that could save nearly 200 million gallons of runoff water lost each day in L.A to the sea. An ambitious proposal Lujac Desautel includes a plan that would save that wasted water and even provide the city a new natural swimming pool.

As WIRED reports, Desautel's idea, Liquifying Aquifers, would feature three concrete structures, each shaped like an inverted pyramid and placed along the Tujunga Wash, a 13-mile tributary of the L.A. river to siphon and clean the water running through it them.

"Desautel proposes using two of the pyramid pools to clean the water with plant-based biofilters," according to WIRED. "Some of that water would flow through conduits into the third and largest pyramid, creating a pool. The rest would be pumped into the aquifer."

Although Desautel's concept is one of many looking to make better use of stormwater, his currently is the only one that includes a swimming pool, which he says is an intrinsic aspect of the California lifestyle.

“The reality is, people live this outdoor lifestyle here,” he told WIRED. “To take this away is to take away the DNA of what Los Angeles is.”
