Project Overview
RRP provided engineering services for a water supplier serving more than 12,400 connections over 100 square miles. We developed a management plan and capital improvement program (CIP) to bring the client into compliance with TCEQ in terms of capacity, elevated storage and pumping capabilities.
We studied the client's previous capacity improvements program and recommended a new technology for the proposed water treatment plant. The new CIP called for spending $13.6 million to increase production by 8 million gallons per day, increase elevated storage by 1 million gallons, and modify facilities to upgrade distribution piping, pumps and motors.

# Barrier Free HCTRA
HCTRA
Harris Co., Texas
Engineering, CEI
RRP provided engineering services for the preparation of drainage reports for three H&H Drainage Segments due to roadway improvements to the Sam Houston Tollway. Project limits span from IH 45 N to SH 225 (approximately 62 miles) and cross Greens Bayou Watershed, White Oak Bayou Watershed, and Buffalo Bayou Watershed. The drainage study focus was to assess potential mitigation needs due to any potentially increased flows from Sam Houston Tollway operational improvements.
Drainage analysis included evaluation of the current Sam Houston Tollway drainage system based on Atlas 14 rainfall data, assessing existing cross drainage structures, and performing an evaluation to determine if the existing roadway and drainage system meets the current TxDOT and Harris County Flood Control District (HCFCD) standards. For the proposed condition, drainage analysis included evaluation of storm sewer trunklines, channel drainage component sizes, assessment of bridge structures (including scour analysis), assessment of drainage crossing structures, and determination of mitigation needs for abutting properties. The drainage impact study and H&H drainage study include applicable hydrologic and hydraulic models prepared with XP-SWMM. The drainage report is a comprehensive compilation of drainage area maps, drainage outfall descriptions, and recommendations for mitigation of impacts. Plans will advance development of hydraulic data sheets and drainage area maps for bridges, bridge-class culvert crossings, and non-bridge-class culverts.
# Detention Pond At Little York & Channel Improvements
Harris County Flood Control District
Houston, Texas
RRP prepared a preliminary engineering report with cost estimates, as well as schedules and a 50% design layout for improvements to channels, culverts and stormwater detention along a Houston bayou.
We prepared detailed hydrologic (HEC-HMS) and hydraulic (HEC-RAS) models to determine peak flows and water surface elevations for storm events at 10, 25, 50, 100 and 500 years, and we utilized on-the-ground surveys to update existing hydraulic models. This project began with a feasibility study to ensure the conceptual plan and subsequent improvements would achieve the set goals for reducing potential flooding.
# Lower Rio Grande Levee Closure For North Floodway At UPRR
U.S. Section of The International Boundary and Water Commission (USIBWC)
Mercedes, Hidalgo County, Texas
ngineering
RRP designed a construction package for two railroad crossings on the US side of floodway levees for the International Boundary and Water Commission (USIBWC). The package included drawings, specifications and opinions on the probable cost of flood protection improvements.
# Old Needville Fairchild Lift Station & Road Reconstruction
Fort Bend County
Needville, Texas
RRP provided engineering and design services to address the utility conflicts and ensure the operation of the sewer system within Texas Commission on Environmental Quality (TCEQ) rules and regulations applicable for sewer systems. A detailed drainage study was done, regrading roadside ditches, replacement of the existing culvert crossings with elliptical culverts to maximize the efficiency of the proposed ditches and smoothly tie in the driveways. As well as proposing new outfall/detention channel. During the preliminary review of the existing design constraints, it has been observed that the most effective solution is to provide a 60,000 gallons per day capacity lift station at the corner of Old Needville-Fairchild Rd. and Stephen St. The lift station will address the elevation constraints and conflicts with other proposed improvements.
# Raymondville Drain Flood Control
Hidalgo County Drainage District #1
Cameron, Hidalgo, Kenedy, Starr, Willacy Counties, Texas
Planning, , CE&I
As a general engineering consultant, RRP coordinated contracts for four engineering firms then developed and implemented a significant phase of a master drainage system. This is a federal project with the US Army Corps of Engineers for flood control in the Lower Rio Grande Basin in South Texas.
# Sanitary Sewer Service To Unreserved Areas Of Minnetex Place
City of Houston
Sanitary Sewer Service To Unreserved Areas Of Minnetex Place And Golden Glades Estates Subdivision Packages I & II
**RRP performed preliminary engineering design for providing sanitary sewer service to two subdivisions, Golden Glades Estates (133 acres) and Minnetex Place (5,595 acres). The study involved analysis of the existing sanitary sewer system, determination of existing and future wastewater flow conditions, and evaluation and comparison of alternative solutions.**
**We developed a conceptual water supply plan for the Minnetex Place subdivision and provided a comprehensive preliminary design to serve Minnetex Place Subdivision completely through gravity systems. We provided multiple design alternatives, construction cost estimates, and recommendations based on hydraulic and cost effective analysis for Golden Glades Estates Subdivision.**
