Key Challenges Water Contractors Face in Southern California

Southern California may be known for sunshine and beaches, but behind the scenes, water contractors are working nonstop to manage one of the region’s most precious — and limited — resources.

From transporting water across hundreds of miles to meeting strict state regulations, these agencies face a mountain of challenges every day.

And as the climate changes and demand continues to grow, their job only gets harder. Let’s break down the biggest issues water contractors in Southern California are dealing with right now.

Droughts

First and foremost: drought. It’s the elephant in the room for every water agency in the state. Southern California depends on water imported from the Sierra Nevada snowpack, the Colorado River, and Northern California via the State Water Project (SWP). But all of these sources are vulnerable to climate change and long-term drought.

When the snow doesn’t fall or the rain doesn’t come, allocations are slashed. Contractors must find ways to stretch limited supplies — or risk running out altogether. This often means enforcing water restrictions, buying expensive backup supplies, or tapping into emergency storage.

Cost of Imported Water

Transporting water over mountains and across deserts isn’t cheap. Water contractors rely on huge infrastructure systems like the California Aqueduct and Colorado River Aqueduct — and maintaining them comes at a high cost.

Add to that the fluctuating price of imported water (based on availability, demand, and energy costs), and local contractors are left with tough budget choices. If imported water is cut or becomes too costly, contractors either pass those costs on to customers or dip into reserves.

Infrastructure

Much of Southern California’s water infrastructure is aging — some pipes and systems date back over 70 years. Contractors face constant pressure to:

• Repair leaks
• Replace pipelines
• Upgrade treatment facilities
• Build new storage or recharge projects

These upgrades are critical for long-term reliability but come with big price tags. Securing funding — through rate hikes, bonds, or state grants — is always a challenge.

Regulatory Pressure

Water contractors must comply with state and federal regulations, many of which change frequently. From drinking water quality standards to groundwater sustainability mandates, the rules can be complex, costly, and time-consuming to follow.

For example, contractors must meet strict limits for contaminants like PFAS (“forever chemicals”), arsenic, and nitrates. Installing the technology to meet these standards — and monitoring it 24/7 — takes significant resources.

Climate Change

Longer droughts, hotter temperatures, and less predictable snowpack all stem from climate change — and they’re making water management more difficult. Water contractors now have to plan not just for seasonal shortages, but for a long-term shift in how water flows in and out of California.

They’re also investing in climate resilience projects — things like water recycling, stormwater capture, and underground storage. But again, these projects take time and money.

Groundwater Limits

With imported water getting riskier, many contractors rely on groundwater. But the Sustainable Groundwater Management Act (SGMA) puts strict rules on how much can be pumped — especially in overdrafted basins like those in Antelope Valley, San Bernardino, and Central Valley.

Water contractors now have to carefully track groundwater usage, report data, and sometimes cut back. In some cases, this limits their ability to serve customers or grow their supply.

Legal Disputes

Water rights in California are complex — and disagreements are common. Contractors sometimes end up in court battles over allocation, well interference, or over-pumping. These legal disputes can drag on for years and eat up resources that could be spent on infrastructure or conservation.

For example, adjudicated basins like Antelope Valley have strict rules, and even small violations can lead to lawsuits or penalties.

Public Pressure

Contractors must also manage public expectations. Ratepayers often want lower bills — but they also expect clean, reliable water and modern infrastructure. Balancing affordability with sustainability is one of the toughest parts of the job.

If a contractor raises rates to pay for necessary upgrades, there can be public backlash. But without those investments, the system could fail during the next crisis.

Here’s a snapshot of the top challenges and how they affect contractors:

Challenge	Impact on Water Contractors
Drought	Cuts to supply, emergency planning
High Import Costs	Strain on budgets, higher customer rates
Infrastructure Needs	Expensive repairs, long project timelines
State Regulations	Costly compliance, monitoring tech
Climate Change	Less predictable supply, long-term risks
Groundwater Restrictions	Limited backup sources, data reporting
Legal Conflicts	High legal fees, delayed operations
Public Expectations	Pressure to keep rates low yet upgrade

Innovation & Solutions

Despite all these issues, many contractors are pushing forward with innovative solutions:

• Recycled water for irrigation and industry
• Desalination in coastal areas
• Smart meters for better tracking and conservation
• Recharge basins to store water underground during wet years

Collaboration between agencies is also growing. By working together, they can pool resources, share infrastructure, and plan for a more resilient future.

Water contractors in Southern California are on the front lines of the region’s water crisis. From battling drought to rebuilding infrastructure, they face huge challenges every day — but they’re also key players in building a sustainable water future.

Knowing their role, and the obstacles they face, helps us appreciate every drop that comes out of the tap.
