4LEAF Inc. begins work on $2.9 million Sacramento sewage vault

The city of Sacramento has approved a $2.9 million contract with 4LEAF Inc. to construct a a new sewage vault underneath McKinley Park.

The project’ will provide a place to store sewage during wet weather, when stormwater runoff — and wastewater — can end up in the same place, and overflow can send it all into East Sacramento’s streets, Capital Public Radio reports.

Under the plan approved last year, a 300-ft. wide and 20-ft. deep tank would hold runoff and sewage under the park. The project is less expensive than dividing the sewer and stormwater systems — which would have cost about $2 billion if implemented.

4LEAF Inc.’s bid to perform engineering, inspection, testing and public outreach work was selected over five others last December.
