Topic: Stormwater



Stormwater runoff has emerged as a primary water quality issue. In urban areas, after long dry periods rainwater runoff can contain accumulations of pollutants. Stormwater does not go into the sewer. Instead, pollutants can be flushed into waterways with detrimental effects on the environment and water quality.

In response, water quality regulators use a range of programs to reduce stormwater pollution including limiting the amount of excess runoff and in some cases recapturing freshwater as well.

Typical stormwater runoff pollutants include:

  • Fertilizer
  • Pesticides/Herbicides
  • Heavy Metals
  • Oil and grease
  • Bacteria/viruses
  • Sediment
  • Construction Waste
  • Trash

Harmful blooms spur more wastewater upgrades

Palo Alto’s bioreactor towers are aging out, like a lot of the clean water infrastructure constructed around the Bay Area in the 1950s-1970s. Recent wind gusts, swirling around the edges of February’s atmospheric river storms, have not been friendly to the towers either. On a March visit to the Palo Alto Regional Water Quality Control Plant, which treats 18 million gallons of wastewater every day, I could see a big chunk missing from the wall of one rusty cauldron and tumbleweeds caught in the metalwork.  Elsewhere on the 25-acre site, the plant’s facilities are visibly undergoing a $193 million overhaul. The overhaul will help the plant meet increasing regulatory limits on the amount of nitrogen that dischargers can pipe into the shallows of San Francisco Bay.

Opinion: Russian River – Saving water from winter storms

The current water year, which began Oct. 1, has been wetter than usual, with the Russian River watershed accumulating 119% of the yearly average rainfall, totaling 49.38 inches since October. In the past, we might have celebrated our good fortune and watched lake levels rise only to watch much of it sent downriver to the Pacific Ocean as reservoirs reached an inflexible upper threshold. Today, we get to continue enjoying that ample rainfall long after summer sunshine arrives. Grant Davis With almost a decade of data under its belt, the Russian River Forecast-Informed Reservoir Operations program has been making great strides by demonstrating the viability of this strategy to operate reservoirs more effectively using modern technology and forecasting.

Metropolitan Water commits up to $250 million for previously untapped water sources

The Metropolitan Water District plans to spend up to $250 million on four non-traditional water projects that, combined, could supply up to 100,000 Southern California households over the next few years. Wastewater recycling, rainwater reclamation and transforming ocean water into drinking water are some of the technologies that could get money in the coming wave of funding from MWD. The Los Angeles-based wholesaler, which helps transfer water from Northern California and the Colorado River to 26 retail water districts in the Los Angeles region, has spent about $700 million on smaller, non-traditional water projects since launching its Local Resources Program in 1990. The amounts announced Monday, April 15, represent some of MWD’s biggest investments in water innovation to date.

News release: Caltrans to construct trash capture device near Tuolumne River in Modesto

The California Department of Transportation (Caltrans) begins construction this month to install a trash capture device along northbound State Route 99, preventing trash in storm water runoff from entering the Tuolumne River at Zeff Road. The trash capture system will be located at the inlet of two existing culverts on the southeast side of SR-99 and the Tuolumne River, a location identified as a significant trash generating area. The project will help the department achieve zero trash from stormwater discharge into the lower reaches of the Tuolumne River. It is consistent with the Caltrans’ Statewide Trash Implementation plan and in compliance with the State Water Resource Control Board water quality objectives for trash pollutants.

Commentary: Environment report: US steps up watchdog role over Tijuana sewage system

Years ago, in a moment of despair over the utter dead-end that solving the Tijuana River sewage crisis seemed to be, I asked U.S. officials why we don’t just cross the border and start fixing broken pipes in Mexico. Nations can’t just cross each other’s borders like that, MacKenzie, the kindly federal official told me. At least, they shouldn’t. It would be a rude mistake. Mexico could consider such federal intrusion without permission as an act of war. But President Joe Biden’s pick to rein in cross-border sewage spills has found a way to leverage her relationships with Mexico to encourage more collaborative U.S. involvement. Maria-Elena Giner announced to reporters during a press conference last week that the International Boundary and Water Commission (the binational agency that deals with cross-border water issues) will start monthly inspections of a key sewage pump and trash shredder in Tijuana that feeds wastewater into San Diego for treatment.

Novato, county scrap with state over fecal pollution

Marin County and Novato are disputing a state water board’s contention that they are doing too little to prevent the discharge of fecal bacteria into the Petaluma River. The San Francisco Bay Regional Water Quality Board notified both the county and Novato in January that they are out of compliance with a program that it adopted in 2019 to reduce the level of fecal bacteria in the river. Both jurisdictions, however, contend that they are not required to comply with the program because the scheme has not yet been incorporated into their municipal storm sewer system permits, which are issued by the State Water Resources Control Board.

SF allegedly dumps big amounts of sewage into creek during storms

When heavy rain overwhelms wastewater treatment plants in San Francisco, causing stormwater to overflow onto streets and into the bay, sewage is an unfortunate part of the mix.  After heavy rain, the largest recipient of the potent brew of stormwater and sewage in the city is Mission Creek — a channel to the bay that is home to houseboats, walking trails and a kayak launch. At Mission Creek, Islais Creek, another channel at India Basin, and a few locations in between, the city discharges 1.2 billion gallons of “combined sewer discharges” in a typical year, according to the environmental group S.F. Baykeeper, which has notified the city it intends to sue over how such discharges impact the environment. A large portion of the combined sewer overflows — which SFPUC said are composed of 94% treated stormwater and 6% treated wastewater — is making its way without basic treatment into the bay during storms, according to S.F. Baykeeper. 

California Water Agencies Hoped A Deluge Would Recharge Their Aquifers. But When It Came, Some Couldn’t Use It
WESTERN WATER IN-DEPTH: January storms jump-started recharge projects in badly overdrafted San Joaquin Valley, but hurdles with state permits and infrastructure hindered some efforts

An intentionally flooded almond orchard in Tulare CountyIt was exactly the sort of deluge California groundwater agencies have been counting on to replenish their overworked aquifers.

The start of 2023 brought a parade of torrential Pacific storms to bone dry California. Snow piled up across the Sierra Nevada at a near-record pace while runoff from the foothills gushed into the Central Valley, swelling rivers over their banks and filling seasonal creeks for the first time in half a decade.    

Suddenly, water managers and farmers toiling in one of the state’s most groundwater-depleted regions had an opportunity to capture stormwater and bank it underground. Enterprising agencies diverted water from rushing rivers and creeks into manmade recharge basins or intentionally flooded orchards and farmland. Others snagged temporary permits from the state to pull from streams they ordinarily couldn’t touch.

Southern California Water Providers Think Local in Seeking to Expand Supplies
WESTERN WATER SIDEBAR: Los Angeles and San Diego among agencies pursuing more diverse water portfolio beyond imports

The Claude “Bud” Lewis Desalination Plant in Carlsbad last December marked 40 billion gallons of drinking water delivered to San Diego County during its first three years of operation. The desalination plant provides the county with more than 50 million gallons of water each day.Although Santa Monica may be the most aggressive Southern California water provider to wean itself from imported supplies, it is hardly the only one looking to remake its water portfolio.

In Los Angeles, a city of about 4 million people, efforts are underway to dramatically slash purchases of imported water while boosting the amount from recycling, stormwater capture, groundwater cleanup and conservation. Mayor Eric Garcetti in 2014 announced a plan to reduce the city’s purchase of imported water from Metropolitan Water District by one-half by 2025 and to provide one-half of the city’s supply from local sources by 2035. (The city considers its Eastern Sierra supplies as imported water.)

The Santa Monica Urban Runoff Recycling Facility (SMURRF) treats dry weather urban runoff to remove pollutants such as sediment, oil, grease, and pathogens for nonpotable use.Imported water from the Sierra Nevada and the Colorado River built Southern California. Yet as drought, climate change and environmental concerns render those supplies increasingly at risk, the Southland’s cities have ramped up their efforts to rely more on local sources and less on imported water.

Far and away the most ambitious goal has been set by the city of Santa Monica, which in 2014 embarked on a course to be virtually water independent through local sources by 2023. In the 1990s, Santa Monica was completely dependent on imported water. Now, it derives more than 70 percent of its water locally.

Thus, even if these impacts were perhaps unbeknownst to the majority of Californians who approved Proposition 64 in 2016, we thought it important to see if anything new had evolved from a water perspective now that marijuana was legal.

For all the benefits of precipitation, stormwater also brings with it many challenges.

In urban areas, after long dry periods rainwater runoff can contain heavy accumulations of pollutants that have built up over time. For example, a rainbow like shine on a roadway puddle can indicate the presence of oil or gasoline. Stormwater does not go into the sewer. Instead, pollutants can be flushed into waterways with detrimental effects on the environment and water quality.
