Repair/renewal solution for small polyethylene water service connections to prevent leakage

WaterStart member faces challenges in implementing an effective and affordable renewal/repair program due to the limited availability of no-dig technologies for small diameter (25-50mm) service connection pipes and is seeking to implement an inexpensive and easy no-dig repair/renewal solution. The current methods of open cut trenching and tunnel boring are costly, time consuming, and disruptive. The reinstatement expenses for sealed roads, driveways, foot paths and lawns add to the expenses and cause inconvenience to customers. Solution must reduce the cost of renewal/repair and minimize customer disruption. It would be preferrable if the proposed solutions could also work with other type of pipe materials, such as galvanized steel, copper and uPVC.

The predominant failures in the service connections are with polyethylene material used between 1970 and 2000, with splits occurring along the length of the pipe. Some service connections may have been installed through a metallic enveloper, which may impact certain no-dig technologies like pipe pulling/extraction and pipe bursting. Additional technical requirements include ensuring that any lining solution can withstand pressures in the range of 20-80m and that costumers are not disconnected from the water supply for more than 24 hours during the renewal/repair process.

Rapid detection of water quality anomalies in the distribution system

Our members are seeking technologies to allow for automated, event-based water sampling. Event monitoring and event sampling are indispensable tools to get detailed information about parameters of a water source, storage dynamics and runoff characteristics. Conventional water analysis is based on manually taken samples, subsequent transport to a specialized lab environment and analysis within a certain period of time. However, due to the high logistic efforts, sampling intervals are usually rather long and can hardly give realistic information about the temporal dynamics of the respective water quality.

Water agencies are interested in new, innovative and real-time water quality monitoring technologies to be utilized for monitoring and/or quality control of treatment processes and distribution systems. They are seeking real-time analysis that can measure a set of routine water quality parameters of the presence of a toxic or otherwise undesirable contaminant.

Needs to be cost effective and low maintenance.

Low-cost, system wide, leak detection for regulatory compliance.

WaterStart member is seeking cost-effective and cost-competitive technologies for leak detection in the water network. Solution must be capable of surveying the entire system (mains and service lines) per the upcoming California Water Loss Performance Standards regulation.

Solution must be in the cost range of $500,000 every 3 years over the entire system, which consists of approximately 1,000 miles of pipe within a 50 square mile area. Would also consider less cost-effective solutions in limited application that could be used in conjunction with the manual approaches of walking/listening if it reduced the number of manhours and miles being monitored. AMI meters are 100% Sensus.

Lessons-Learned Digital Platform

WaterStart member is looking for an intuitive solution for the capture of internal operational insights. The ideal platform should be quick and easy to use, accessible for any device at any time with low administrative requirements. Sought platform should be customizable allowing operators to add data fields such as title, description, category, date, etc., with an ability to share visual content.

The ideal platform should empower user collaboration and engagement, including functions such as searching, ratings, comments, and email integration. Analytical tools are also desired to draw insightful data across the business. Please note, our members will consider existing platforms with proven use-cases only.

Anti-Theft of Backflow Prevention Device

WaterStart member is seeking a solution to assist with the security and tracking of backflow prevention devices installed across the member drinking water network. To investigate and mitigate future theft incidences, the member seeks a simple and cost-effective retrofitted solution for the GPS tracking of backflow units.

Units deployed are Backflow Prevention Devices (3/4” – 2”), constructed of brass. Sought technology must be small and inconspicuous for deployment. The ideal solution will also require a long battery life. While immediate knowledge of the loss is not required, it would be highly beneficial.
