Highlands Siphons Baytown,TX 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

North Fort Bend Water Authority Houston,TX RG Miller | DCCM assisted with the design of 10,400 LF of 12″, 16″, 20″ and 24″ diameter water lines and appurtenances, preparation of bid and construction documents and the construction phase services.  

Reclaimed Water System Feasibility Study (Dowdell) Klein,TX RG Miller | DCCM  prepared a detailed feasibility study for the implementation of reclaimed water system serving 30 water demand sites.  The study outlined planning, design, and implementation regulatory requirements for the use of Type I reclaimed water under Title 30, Chapter 210 of Texas Administrative Code.  The project identified over 30 potential demand sites for reclaimed water including both irrigation areas and amenity pond make up water. Treatment technologies were evaluated and implementation costs were estimated.  Total capital costs were estimated to be $10.8 million.  Total avoided water purchase costs were estimated to be 1.8 billion gallons from 2015 to 2044.  The avoided water purchase costs were estimated to be about $14.8 million over that same time horizon.  Total expenditures, with interest payments included, were estimated to be $12.1 million; yielding a savings of $2.7 million.  If “alternative water” incentives offered by the regional water authority were included, total savings increased to $4.4 million over the planning time horizon.  

SJRA Water Route C4 Montgomery County,TX This project consisted of the design and construction of the San Jacinto River Authority Ground Water Reduction Program Project C-4. C-4 is a 24-inch waterline from Old Egypt Road (connection to C-2) to the City of Conroe Water Plant 15 and connection to C-3. The line was placed along FM 830, under IH 45 and along SH 75 in southern Montgomery County. The line was designed using open cut and trenchless operations like the 400 liner foot tunnel section under the main lanes of IH 45.
