As a result of a Sanitary Survey Inspections conducted by the Nevada Division of Environmental Protection, Bureau of Safe Drinking Water (NDEP-BSDW), the Department of Utility Services has identified 24 AVARs (Air Vacuum Air Relief Valve) at multiple locations throughout the City for replacement and/or upgrades. Some of these AVARs are not equipped with screens. Some were installed underground which at times due leaking water pose a health hazard due to potential backflow condition.

AVAR Valve Replacement - Key Map

During a sewer condition assessment survey, the City identified a damaged 18-inch diameter sewer main near the Pittman Wash and Valle Verde Drive. The damaged pipe section is approximately 105 feet and is located adjacent to and under the southern footing of the Valle Verde Bridge at Pittman Wash. Multiple partially collapsed pipe segments have been identified within the damaged reach of pipe.

This project will provide realignment of approximately 270 LF of 18-inch sewer constructed adjacent to the existing concrete apron and will tie into the existing 24-inch sewer under the northerly access road in the wash. An extended concrete apron and cutoff wall will also be constructed in the wash.

The Sewer Main Rehabilitation Phase 2 project improvements include miscellaneous repairs and replacement of aging and failing infrastructure at various locations within the City of Henderson’s sanitary sewer collection system.

The R-13B Reservoir / R5 Reservoir Drainage Improvements Project consists of two main elements:

1. The construction of a new 2 million-gallon (MG) R-13B Reservoir at the south end of Stephanie Street within the MacDonald Highlands neighborhood, including site piping, grading, drainage, electrical, and SCADA/control. This project is intended to provide resiliency to the City of Henderson’s water supply by expanding the water storage capacity.
2. The construction of a concrete open channel on an existing 20-foot municipal utility easement adjacent to Site 5 (near Dunrobin Garden St and Austin Rose Ave) to convey overflow discharge from R-5 or R-5A Reservoirs. This project also includes grading and all other related work and appurtenances.

During the construction period, there will be no impacts to water or sewer services. Construction traffic will enter both project sites from residential roads, but there are no anticipated road closures or lane restrictions. The Construction Access Map for the R-13B Reservoir is provided below. Construction traffic is anticipated to be minimal with no major disruptions. Construction hours are 6 am to 6 pm Monday – Friday. Weekend work is not anticipated.

The water and sewer mains in the Townsite area, an older neighborhood established in the 1940s, have reached the end of their useful life and need replacement and/or relocation, along with associated paving improvements.

Water Service Lateral Inventory & Inspection

The initial Lead Service Line Inventory was compiled and submitted to the Environmental Protection Agency (EPA) on 10/16/2024, in compliance with the EPA mandate.

A visual inspection was performed on a representative sample of laterals connected to buildings built before 1989, when the Nevada Lead Ban was enacted, and no lead was found. In order to maintain compliance with Lead and Copper Rule Revisions, the City of Henderson will continue to inspect water service laterals through the next inventory submission deadline at the end of 2027.

City Water and Infrastructure

The City of Henderson's water infrastructure does NOT contain lead service lines. The City monitors for both lead and copper and testing results demonstrate that both are at levels well below state and federal requirements.

The City of Henderson is responsible for providing high-quality drinking water but cannot control the variety of materials used in home plumbing components. Homes built before 1989 are more likely to have lead-based plumbing components.

EPA's Lead and Copper Rule

In December 2021, the U.S. EPA took a series of actions to improve the Lead and Copper Rule that are intended to better protect families and communities in years to come, particularly those that have been disproportionately impacted by lead in drinking water. One of the new requirements is for municipal water companies to complete an inventory of all water service line materials with an emphasis on locating any lead materials. 

EPA’s new guidance will assist water systems in developing and maintaining service line inventories, support notifications to consumers served by lead pipes,  and provide states with needed information for oversight and reporting to EPA.

Lead at elevated levels can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing.

When your water has been sitting for several hours, minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your tap water, have your water tested by a private laboratory.
