Protecting Our Water Supply:Actual Water Usage Matters More Than Theoretical Estimates

Dear Friends and Neighbors

As development continues to increase throughout our town and hamlets, one question has become increasingly important: How much water will these new developments actually use?  The answer matters because every new home, apartment, townhouse, or housing complex places additional demand on our municipal water system. If the demand exceeds the available supply, existing residents and future residents alike could face water shortages, reduced system reliability, higher costs, and expensive infrastructure upgrades. Unfortunately, many development reviews rely heavily on standardized formulas rather than actual water consumption data. While these formulas serve an important purpose, they do not always provide a complete picture of the real demand that a development may place on a local water system.

Design Standards Versus Real-World Usage
New York State requires engineers to use standardized calculations when designing wastewater systems and estimating future demand. These formulas are typically based on factors such as the number of bedrooms in a home.

The purpose of these standards is to ensure that infrastructure is designed safely and conservatively. However, there is an important distinction: Design standards estimate what a development could use. Actual water meters reveal what developments really use. These are not always the same. A development may be approved based on projected demand, but once occupied, the actual water consumption may be significantly higher or lower than anticipated. The only way to know for certain is through metered water-use data.

Why Actual Water Usage Data Matters
Every gallon drawn from a municipal water system must come from somewhere.
Water is supplied by wells, reservoirs, pumps, storage tanks, and distribution systems that have physical limits. Those limits cannot be ignored.

When evaluating whether a water district can support additional growth, decision-makers should understand: current water demand, peak summer demand, maximum daily demand, demand during drought conditions, water losses within the system, water already committed to approved but unbuilt projects and actual usage by comparable developments. Without this information, approvals may be based on assumptions rather than demonstrated capacity.

A Simple Example
Imagine a water district has the capacity to provide 300,000 gallons of water per day.
Current demand averages 250,000 gallons per day. A proposed development estimates it will require 40,000 gallons per day. On paper, the project appears acceptable because the total demand would be 290,000 gallons per day. However, what if similar developments that were approved using the same assumptions are actually consuming 55,000 or 60,000 gallons per day? Suddenly, the available reserve capacity disappears. If multiple developments are approved using underestimated projections, the community could eventually face a situation where demand approaches or exceeds available supply.

Learning From Existing Developments
One practical solution is to require water-demand analyses based on actual metered consumption from comparable occupied developments. For example, if a proposed project consists of 100 residential units, the Town Engineer could review water usage records from similar developments already connected to the system. This approach allows decision-makers to compare projected demand versus actual demand, seasonal water usage patterns, peak demand periods and long-term consumption trends. Rather than relying solely on theoretical estimates, officials can evaluate real-world performance.

Building a More Sustainable Approval Process
A community does not need to oppose development to support responsible planning.
Instead, the goal should be to ensure that growth occurs only when adequate water resources are available. Local regulations could require that developers demonstrate sufficient capacity using actual consumption data from comparable projects, together with current information regarding available well capacity, safe yield of water sources, existing system demand, future committed demand, emergency reserve requirements and drought contingency planning. Such safeguards would allow growth to proceed responsibly while protecting existing residents and future homeowners.

Why This Matters
Water is one of the most critical public resources a community possesses. Unlike roads or buildings, water cannot simply be expanded overnight when shortages occur. New wells, treatment facilities, storage tanks, and distribution upgrades often require years of planning, permitting, and construction. That is why communities must understand not only what a development is projected to use, but what similar developments actually consume once occupied.

Using real-world water-consumption data provides a more accurate picture of future demand, helps identify potential capacity concerns before they become crises, and supports informed decisions about sustainable growth. Responsible planning is not about stopping development. It is about ensuring that growth does not outpace the resources upon which existing residents and future generations depend. Before additional connections are approved, communities deserve confidence that their water supply can sustainably support them. The best way to achieve that confidence is through accurate data, transparent analysis, and decisions grounded in real-world water usage rather than assumptions alone.

Fallsburg's Future is a community network of concerned Fallsburg residents established in January 2016. Its Mission is to help guide the urban development of the town of Fallsburg and its five hamlets, to promote its sustainable economic development, protect the fragile beauty of its natural habitats and enhance the opportunities and quality of life for all its residents and visitors. We hope to curb the suburban sprawl that is threatening to overwhelm the town’s physical infrastructure and destroy the natural beauty that the area depends on for its future development.
