Management & Planning

The goal of NapaSan’s management team is to be forward-thinking – to anticipate the wastewater treatment needs of the community and to have the infrastructure and processes in place at the right time to ensure that we can meet those needs.

Additionally, NapaSan strives to keep costs down and to increase resource efficiency by reducing energy use and increasing the production and distribution of recycled water.

In order to meet these goals, NapaSan has prepared strategic plans for key functional areas. These plans help identify priorities, needed improvements, project alternatives and potential timelines. In short, these documents provide a road map forward to allow NapaSan to be successful in providing excellent wastewater collection, treatment and disposal service.

NapaSan Strategic Plan

The purpose of the Strategic Plan is to describe the goals, objectives and priorities of NapaSan. The Strategic Plan was developed through a series of discussions involving the NapaSan Board of Directors and NapaSan Department heads. The current version of the plan was completed in May 2015.

Performance Measurement Reports

After the end of each calendar year, NapaSan prepares a Performance Measurement Report. The report includes performance measures that, when taken as a whole, provide a snapshot of how well the organization is performing and being managed. This report highlights areas where NapaSan is performing well, but just as importantly, it also identifies areas that need improvement. This information can feed into work plans for the coming year.

NapaSan uses the Effective Utility Management  (EUM) framework for presenting this information. This framework is specific to water and wastewater utilities and provides for the possibility of comparing NapaSan to other wastewater utilities once more providers begin using EUM for measuring and reporting on performance.

Wastewater Treatment Plant Master Plan

NapaSan completed a Wastewater Treatment Plant  (WWTP) Master Plan in April 2011. The Plan determines the capacity of existing facilities, estimates future loads and regulation impacts, and develops a recommended plan for upgrading existing facilities.

Strategic Plan for Recycled Water Use

NapaSan completed the Strategic Plan for Recycled Water Use to determine a recycled water planning approach through the year 2020. The plan considers seven strategies, ranging from recycling only enough water to meet NPDES permit requirements, to recycling all water available. In examining all the strategies, NapaSan considered treatment, storage and distribution system requirements as well as capital and operation and maintenance costs. NapaSan also wanted to factor in the cost to sewer customers and the responsibility to augment local water supplies. The plan evaluates all the recycled water strategies and makes recommendations.

Communications Plan

In 2016, NapaSan completed a long-range strategic communications plan to prioritize communication strategies, identify important messages to convey to the community, and identify the best outreach methods to convey these messages to the community.  The Communications Plan can be found here.

Collection System Master Plan

In 2007, NapaSan completed a Collection System Master Plan. The collection system is the network of sewer pipes that collect wastewater and carry it to the treatment plant. This plan evaluates the condition and performance of the sewer pipe collection system under both current and future (year 2030) build-out conditions. The Master Plan concluded that while the collection system has adequate dry weather capacity to handle anticipated growth, it has inadequate capacity for existing wet-weather peak flows due to excessive inflow and infiltration (I/I) entering the system. I/I occurs where there are breaks in the sewer main and lateral pipes that allow rainwater or groundwater to enter the sewer pipe system.
The Master Plan concludes that the most cost-effective solution is a mixture of I/I reduction projects and capacity upgrades to handle peak flows, as opposed to wholesale capacity upgrades to the system. Based on this recommendation, NapaSan has initiated pilot projects to determine the sources of and best approaches for reducing I/I to the collection system.

Capital Improvement Program

NapaSan’s Capital Improvement Program, or CIP, is a ten-year plan that identifies capital projects and equipment purchases, provides a planning schedule and identifies options for financing the plan. Essentially, the plan provides a link between NapaSan’s strategic plans and its capital budget. This plan is incorporated into the Annual Budget.

Energy Alternatives Study Project Implementation Plan

In 2010, NapaSan completed an Energy Alternatives Study to evaluate wind, solar, and cogeneration power generation requirements. The study determined that wind generation was not feasible because of inadequate wind speeds at NapaSan sites. The study also found that photoelectric (solar) generation is not viable at this time for full scale production, due to costs.

The study’s top recommendation was the immediate installation of a fat, oils and grease (FOG) receiving station. The breakdown of FOG in the treatment plant’s digester creates large amounts of methane gas that can be used to fuel generators (known as cogeneration) at the wastewater treatment plant. This power generation reduces demand for purchased electricity at the plant. NapaSan completed construction of the FOG receiving station in July, 2012.

Winery Waste Management Technical Memorandum

In 2008, NapaSan determined that there were a number of wineries or winery-related businesses operating within its service area that are not regulated by NapaSan. These businesses potentially have on-site activities that are incompatible with NapaSan’s Industrial Pretreatment Program requirements, and/or are discharging wastewater in excess of purchased capacity for the property.

To address these issues, the NapaSan implemented a study to analyze various strategies for addressing winery waste within NapaSan’s service area. The Winery Waste Management Technical Memorandum, completed in October 2009, recommended managing these discharges through the existing Industrial User permitting program as the most feasible of several options.
