(b) An indirect cross connection is an arrangement whereby unsafe water, or other liquid, may be blown, siphoned, or otherwise diverted into a safe water system. Such arrangements include. Water supply system - Water supply system - Surface water and groundwater: Surface water and groundwater are both important sources for community water supply needs. Groundwater is a common source for single homes and small towns, and rivers and lakes are the usual sources for large cities. Although approximately 98 percent of liquid fresh water exists as groundwater, much of it occurs very. Storage should meet peak flow requirements, equalize system pressures, and provide emergency water supply. The water supply system must provide flows of water sufficient in quantity to meet all points.

Where the water pressure in the public water main or individual water supply system is insufficient to supply the minimum pressures and quantities specified in this code, the supply shall be supplemented by an elevated water tank, a hydropneumatic pressure booster system or a water pressure booster pump installed in accordance with Section 606.5.5. In hot water systems with circulation system the temperature at the return is at least 60°C. Drinking water is not warmer than 25°C. For hot water at the tap the maximum waiting time is 20 + 15 seconds. 20 seconds for the pipe and 15 seconds for the hot water producer 2.3.

Welcome/about this guide

Water. H2O. Most of us in Northeastern Illinois don’t pay much attention to our drinking water. We turn on faucets dozens of times a day without pausing to consider the questions that millions of people around the world worry about on a regular basis: Do we have enough? Is it clean? Will it endure?

We are lucky: In Northeastern Illinois, our proximity to a Great Lake means we generally enjoy ample water. But that good fortune has lulled us into complacency, and our drinking water systems have been neglected. Our proverbial glass is half empty.What’s at stake? Public health and safety, including contamination and service disruptions due to crumbling infrastructure and aging water treatment systems. Our ability to attract jobs and drive regional economic growth—since every company needs water. Vital, yet fragile, ecosystems. Municipalities and their residents, who find themselves hard-pressed to pay the escalating costs of collecting, treating and delivering drinking water. And, yes, some groundwater sources may be unusable in less than 15–20 years.

While our water supply issues are significant, they are fixable.

You can help.

Water systems are connected

There are three components to water service infrastructure: drinking water, wastewater and stormwater. While this guide is focused on drinking water, it is important to understand that these systems are ultimately interconnected.

As a local leader, you set the tone for the rest of your community. What decisions will you make and actions will you take to ensure your community has safe and reliable drinking water now and into the future? What best practices will provide sustainable drinking water service for the communities you serve? Informing yourself about the systems and processes that convey safe drinking water to your municipality’s residents, businesses and institutions is vital.

Elected officials often enter office without prior experience in water resource management or running a water utility. This guide is designed to support you—our leaders—in understanding the key aspects of water management and critical questions to discuss with your water system managers and engineers, municipal planners, public works officials, finance directors, developers, residents and businesses. What practices are important today? What do other communities often forget? How can you best serve your community and support sustainable water service? Find answers to these questions—and more—here.

Drinking Water 1-2-3 is a call to action and an educational tool for local officials and community leaders to better understand and proactively address their area’s drinking water needs.

This guide is a manual that provides information about water resource management, service, infrastructure and planning. It helps you identify important strategies and actions for you and your community to take today.

It takes strong leadership from community officials to marshal political will, head off calamities and create a sustainable water future for our region.

As a local leader, you hold the key to making sure your community has a safe and sustainable drinking water system now and into the future. The decisions you make, the actions you take (or do not take) regarding drinking water will impact the people, businesses and ecosystems in your region for decades. As this guide has outlined, we have significant challenges to overcome, but they are fixable. The actions in Drinking Water 1-2-3 will help, but it takes strong leadership from you.

Residential and Type III Public Water Supplies

Before construction of a private or type III public water well, or making extensive changes to an existing well, a person must provide District Health Department No.2 (DHD2) with a Notification/Permit Form describing the intended water well location and construction. The Notification/Permit Form must be purchased, completed and then submitted to DHD2 for approval at least four (4) business days in advance of well construction.

Construction of water supplies must comply with the state’s Well Construction Code and with DHD2’s local sanitary code. The Health Department conducts final inspections on completed wells at select locations to assure compliance with the Well Construction Code. Predrilling Site Evaluations and/or Random Construction Inspections will be conducted on the remaining well sites.

Wells must be constructed by well drilling contractors registered in the State of Michigan. A person may construct a well for their own home; however they must submit a Notification/Permit Form first, comply with construction codes, and be given written authorization from the Health Department to construct their own well based on a pre-drilling site visit.

Additional fees and inspections may be required for persons that wish to keep an existing well at locations where a new replacement well is constructed. Related information can be obtained by clicking here for Water Supply Policies.
