A Water and Sewer Study is performed to determine the impacts that a prospective development may cause to the current Vallecitos Water District's infrastructure. This determination will dictate whether the current system can accept the sewer and provide the water necessary to not only service the development, but to provide enough flow for a potential fire event.

A development proposing four dwelling units or more will be required to have the Water and Sewer Study completed prior to processing a plan check. The study should be completed as early in the development process as possible. The preliminary results of the study may show that the owner/developer must construct and install system upgrades to the current infrastructure. VWD shall determine when revisions to an existing Study are necessary.   The Water and Sewer Study is not all inclusive of the conditions for the development project, additional requirements may be identified during the plan check process. 

Water and Sewer Study Requirements

Assessor’s Parcel Numbers (APN’s):
All existing properties affected by the proposed development should be clearly identified by Assessor’s Parcel Numbers, street address information and acreage.

Site Plan:
A proposed site plan shall be submitted to the District for use in preparing the study. Changes in the proposed development may require an update to an existing study. Typical changes for more review may be the number or type of units, changing the points of connection, increased development, and the District's adoption of new planning documents.

• Land Usage
  A breakdown of the land usage by acreage proposed for the project; Commercial, Residential, Open Space, Right-of-Way, etc., shall be included in the submittal.
• Dwelling Units/Commercial Units
  The number and type of proposed units and description included in the Site Plan.
• Points of Connection
  The proposed points of connection to the existing water and/or sewer systems to be studied.
• Tentative Map - Map being reviewed and processed with the lead Agency. City or County.

Fire Flow
The Fire Agency (local) must review the plan and provide fire flow requirements for the project.
