Situated in one of the world’s most arid regions, Israel has been overcoming water shortages and desertification since its inception in 1948. Its diverse topography, which includes plains, mountains, deserts, and coastlines, makes for many water challenges. A small country at 8,019 square miles (about the size of New Jersey), Israel sustains a population of 6.35 million people.

Despite the roar from the municipal water and wastewater industry about the lack of funds for infrastructure, Water & Wastewater News’ roundtable participants seemed to agree that the money is “out there,” it is just a matter of finding the right source.

A new generation of biological water treatment recycle systems
Construction is risky. Few projects move from start to finish without problems, and -- more often than not -- problems leads to unanticipated costs, unacceptable delays, finger-pointing, disputes, frustration, aggravation, and -- nightmare of nightmares -- litigation.

Water quality is intimately connected to quality of life. Although this fact of life has been understated for many years, water professionals have long known that clean water is an increasingly scarce and valuable commodity that cannot be taken for granted. The Clean Water Act brought about increased regulatory oversight, resulting in recent criminal charges and fines against violators, and environmental organizations are succeeding in bringing about public awareness of the need to protect water resources by encouraging businesses to include water stewardship and utilization in corporate sustainability reporting.

The City of Orlando in Florida treats up to 40 million gallons a day (mgd) of wastewater at its Iron Bridge Regional Water Reclamation Facility. The city bills one major upstream source based on the amount of wastewater treated. Both parties want accurate flow measurements to ensure a fair assessment of costs. A few percentage points of error can quickly add up to thousands of dollars in questionable billings.

Facilities in the United States and Puerto Rico that consistently achieve outstanding environmental results may be eligible for recognition and regulatory incentives through a voluntary program of the U.S. Environmental Protection Agency (EPA). The National Environmental Performance Track, launched by EPA in June, 2000, recognizes and rewards top environmental performers and is designed to encourage continual improvement.

For more than 30 years the Clean Water Act (CWA) has established programs and requirements to protect the quality of U.S. rivers, lakes, and coastal waters. In that time, this regulatory framework has succeeded in doubling the number of water bodies in the United State that are considered swimmable and fishable. Today, according to the U.S. Environmental Protection Agency (EPA) more than two thirds of water bodies are regarded as healthy compared to only one third in 1972 when the CWA was first created by Congress.

Imagine that you are in the final stages of constructing a 10-filter water-treatment plant. Startup for the filter control system alone requires the contractor to coordinate with representatives from the valve supplier, actuator supplier, instrument supplier, filter console supplier, the electrician and the integrator to put together a system that is supposed to work as one complete unit.

Traditionally, training has often been approached as an afterthought -- a vendor demonstrating a specific product to operators after the product has been purchased and installed. But in today's highly competitive marketplace, training is an important part of the whole solution. Training provides operators with tools and insights that can help them lower costs and improve efficiency plant wide.

All drinking water treatment plants (WTPs) must dispose of their potable water residuals. One privately owned water utility in Fairbanks, Alaska, uses a filter press to dewater its water treatment mineral byproducts. By doing so, the utility achieves zero discharge to the nearby Chena River, which serves as a recreational area and spawning ground for several fish species threatened with possible extinction.

Groundwater contamination has been an area of environmental concern for decades. Underground storage tank and process line leaks, product spills and intentional dumping have been the greatest contributors to the problem.

Whole effluent toxicity (WET) testing has evolved into a critical element of many National Pollutant Discharge Elimination System (NPDES) permits issued to both industrial and municipal dischargers. More than 6,500 dischargers to both fresh and salt waters are required to conduct toxicity tests to determine if their effluent might be potentially toxic to organisms in the receiving system.
