Emergency Operations and ERPs

Community water systems serving populations greater than 3,300 are required to have a plan in place for emergencies in accordance with America’s Water Infrastructure Act of 2018 (AWIA) section 2013(b), which amended Safe Drinking Water Act (SDWA) section 1433(b). According to U.S. EPA, Emergency Response Plans (ERPs) describe "strategies, resources, plans, and procedures utilities can use to prepare for and respond to an incident, natural or man-made, that threatens life, property, or the environment. Incidents can range from small main breaks or localized flooding to large scale hurricanes, earthquakes or system contamination, among other examples." ERPs must outline the steps a system should take to ensure the continuation of service during an emergency. The Arizona Department of Environmental Quality has provided an O&M Manual Template that can be used as a starting point in developing a manual from scratch or making improvements to existing emergency O&M procedures. 

They also provided the following list of emergency situations and provisions that community water systems need to address in their ERPs: 

• Loss of source
• Loss of water supply due to major component failure
• Damage to power supply equipment or loss of power
• Contamination of water in the distribution system from backflow
• Collapse of a reservoir, reservoir roof or pumphouse structure
• A break in a transmission or distribution line
• Chemical or microbiological contamination of the water supply

Within these sections of your utility's manual, include provisions for providing alternate water, notice procedures for regulatory agencies and users, disinfection and testing techniques, critical component identification, spare parts inventory and staff training in emergency response procedures.

What Is a Cluster System?

According to U.S. EPA: "A cluster (or community) decentralized wastewater treatment system is under some form of common ownership and collects wastewater from two or more dwellings or buildings. It conveys the wastewater to a treatment and dispersal system located on a suitable site near the dwellings or buildings. It is common to find cluster systems in places like rural subdivisions."

Cluster systems transport wastewater from a small number of homes (typically 2-10) via alternative sewers to either a conventional treatment plant or to a pretreatment facility followed by soil absorption of the effluent. Cluster systems can be financially sound, environmentally friendly solutions for small community wastewater problems, where conventional central treatment systems are not practical or affordable and where individual onsite systems are inappropriate because of site or soil limitations. 

The advantages of cluster systems are the lower average cost, flexibility in land use, less complex operation and maintenance for the community, and non-discharging, decentralized wastewater treatment systems can provide an environmentally sound alternative for small or disadvantaged communities.

The main disadvantage of cluster systems is the amount of operation and maintenance needed. While it is typically not complicated, alternative sewers have septic tanks that need to be inspected and pumped and mechanical parts and controls that use electricity. Since cluster systems are located onsite, workers are required to travel to individual homes or businesses. This type of decentralized wastewater system requires more frequent maintenance, which can be costly if anything is malfunctioning. 

Another key thing to keep in mind is that cluster systems require a somewhat complex organizational structure in order to make community decisions like fee collection and continuing education of homeowners about wastewater issues. The cooperation of homeowners using the cluster system is much more important than with municipal systems since smaller systems are less resilient and less tolerant of periodic large flows or larger than normal loadings of household chemicals than in large systems, where these peaks are averaged out over a very large user base.

A Case for Regionalization

Water and wastewater services are needed in every community in order to sustain it, but some communities need more assistance in order for their water utility to thrive. Many rural areas face challenges like meeting strict regulations while still providing affordable services to users. As technology becomes more sophisticated, the need to purchase new, expensive equipment becomes unavoidable for small utilities that often do not have the funding or resources needed. This is when regionalization can really benefit utilities and their customers alike.

Regionalization helps two or more water systems to leverage and combine resources, equipment, personnel, and even physical plants. According to U.S. EPA, “the main benefit of regionalization is that it pools individual resources of two or more water systems to obtain services or facilities that one or both systems may not have been capable of obtaining by themselves.”

In the Rural Community Assistance Partnership's (RCAP's) 2021 report: Affordability and Capability Issues of Small Water and Wastewaters Systems: A Case for Regionalization of Small Systems, they feature a case study that shows a successful model for regionalization from the Greater Cincinnati Water Works (GCWW) in southwest Ohio. GCWW offers the smaller water systems in the area much assistance in the form of: lab testing services, billing services, call center operation, a source of project financing, construction management services, engineering services, and emergency help when needed. 

RCAP also released a report titled: Regionalization: RCAP’s Recommendations for Water and Wastewater Policy which contained 22 recommendations that should be integrated into policy decision-making. The research featured in this report was unveiled in a webinar that also focused on the experiences of five different states: California, Florida, Ohio, Pennsylvania, and Texas, who spoke about what they have put in place to help support the various forms of regionalization.
