Districts seek engineering firm for wastewater pumping project

The Pagosa Springs Sanitation General Improvement District (PSSGID) and the Pagosa Area Water and Sanitation District (PAWSD) referred to individually, or together as districts, are seeking an engineering firm to provide engineering services related to planning and design of a wastewater pumping conveyance system to convey wastewater generated by the PSSGID service district to the Vista Wastewater Treatment Plant, located at the PAWSD Lyn Avenue Campus, for treatment and disposal.

It is envisioned that the system will consist of the following two phases, namely Phase A and Phase B; the PSSGID will be responsible for the construction of Phase A, consisting of permitting and design for a lift station to be built at a suitable location selected by the design engineer at the eastern terminus of the project and a pipeline of the largest diameter practical to accommodate for as much future expansion as is reasonably foreseeable, as determined by the design engineer extending from the lift station and continuing along an alignment as selected by the design engineer to a point of discharge at the site of the Phase B lift station.

PAWSD will be responsible for the construction of Phase B, consisting of permitting and design for a second lift station erected at a suitable site selected by the Design Engineer and a pipeline of the largest diameter practical to accommodate for as much future expansion as is reasonably foreseeable, as determined by the design engineer extending from the Phase B lift station continuing along an alignment as selected by the design engineer to a point of discharge to the PAWSD Vista Wastewater Treatment Facility.

PAWSD presently has a raw water pipeline from the San Juan River to the Lyn Avenue Campus which encompasses the San Juan Water Treatment Plant and the Vista Wastewater Treatment Plant, either in a 50-foot-wide easement or road Right-of-Way for approximately two-thirds of the envisioned route. The preferable design would be to parallel this raw water pipeline. The districts intend to pursue trench cost sharing with other entities such as, but not limited to, natural gas, electrical, communications, potable water, trails, etc., without adding undo time to the project. The selected Firm would only be responsible for inclusion of and design for wastewater, and water infrastructures, if so desired by the districts, unless written authorization is issued by the districts for an expanded scope. Design services for other utility infrastructures would remain with the respective utilities.

The successful Firm will be responsible for development of a Preliminary Engineering Report (PER) in conformance with the requirements of the Colorado Department of Public Health and Environment (CDPHE), as well as simultaneously publishing an abbreviated feasibility study. Portions of the information needed for the PER have already been established in the form of a mechanical treatment plant PER previously submitted to and approved by the CDPHE, and will be made available to the Firm for use in preparing the PER for this project. The Districts have developed an estimate of probable costs, as well as a tentative alignment for use in preparing the PER and related feasibility study based on a project of similar scope, which has been completed within the last 30 days. The planning of this project will occur such that construction will commence in the 2012 construction season. Construction oversight will be furnished by the districts.

Interested firms should submit nine bound copies of the Statement of Qualifications by 4 p.m., Tuesday, Jan. 31, 2012, to the PAWSD Office (address below). After review and evaluation of the Statements of Qualifications, the committee may select a firm based on the written qualifications or may interview any number of firms prior to selection. The Districts reserve the option to delay or not select a firm if deemed appropriate for any reason. The districts plan to select a firm by approximately 4 p.m., Friday, Feb. 2, 2012. All materials contained in the Statements of Qualifications will be held in the strictest of confidence.

Interested firms can contact the PAWSD project manager for additional information, the expanded formal RFQ, and questions and clarifications concerning the project.
