Highlands Siphons

Highlands Siphons

Project Description

The North Main Siphon consisted of one 42-inch reinforced concrete (RCP) siphon pipe with supporting headwall structures at each end. This existing 42-inch RCP siphon was extended downstream by 60 linear feet to accommodate the expansion of North Main Street pavement widening project by the Harris County Public Infrastructure Department (HCPID) and the City of Baytown (COB) 12-inch sanitary sewer adjacent to the HCPID project. Project was completed on time for a construction cost of $427,461.00

The Garth Road Siphon consisted of the upgrade of a single 48-inch RCP siphon to dual 48-inch CCFRP siphons. The upgrade was done due to the near future plans of the Harris County Public Infrastructure Department to widen Garth Road and to provide increased flow necessary for the downstream end users. A downstream sluice gate will be removed and the canal reconstructed to maximize flow capacity. Project is currently under design with an Opinion of Probable Construction cost estimate of $1,300,000

The Wallisville Road Siphon consisted of the upgrade of a single 48-inch RCP siphon to dual 48-inch CCFRP siphons. The upgrade was done due to the near future plans of the Harris County Public Infrastructure Department to widen Wallisville Road and to provide increased flow necessary for the downstream end users. The dual 48-inch siphons were extended downstream to replace the 90 degree bend from open channel to underground. This will eliminate the continued maintenance of the eroded channel side slopes due to water forces. Project is currently under design with an Opinion of Probable Construction cost estimate of $1,300,000
