Key Terms

wastewater, groundwater storage, water treatment, automation

4 terms

wastewater technical

"strengthening water and wastewater infrastructure across the state"

Wastewater is the used water and liquid waste that flows from homes, businesses and factories—everything from sinks and toilets to industrial runoff and process liquids. It matters to investors because collecting, treating and disposing of this water drives costs, regulatory exposure and business opportunities: like a city’s plumbing, failures require costly fixes while upgrades or treatment technologies can create revenue for utilities, construction, and environmental-tech companies.

groundwater storage technical

"New groundwater storage in Isleton: Bringing much needed water storage capacity"

Water held beneath the ground in layers of soil, sand or rock that acts like a natural storage tank for drinking, irrigation and industrial use. For investors, groundwater storage matters because it influences how reliable and costly a water supply will be, affects the value of land and utilities, and shapes regulatory and drought risk — like a savings account that communities draw on when surface water runs low.

water treatment technical

"Major water treatment upgrades in Monterey: Our large Iron removal plant"

Water treatment is the process of cleaning and preparing water so it is safe for drinking, industrial use, or release back into the environment, using physical, chemical, or biological methods to remove contaminants. Investors care because water treatment systems are essential infrastructure with steady demand, regulated standards, and recurring revenue potential—think of it like a city's filtration and billing system that keeps a community running and generates predictable income for companies that build, operate, or supply them.

automation technical

"Technology and operational efficiency upgrades including automation and system monitoring"

Automation is the use of technology to perform tasks with minimal human intervention, often replacing manual work with machines or software. It matters to investors because it can increase efficiency, reduce costs, and enable faster decision-making, potentially leading to higher profits and competitive advantages for businesses.
