Water Storage TanksTown of Silverthorne, Dillon, COThe Town of Silverthorne, CO is divided into 5 pressure zones. The water is pumped from wells in the valley to the storage tanks for service. The 1.0 MG buried post-ten-sioned tank provides water service to the Town, but also works as emergency service for the towns of Dillon and Dillon Valley.

MME and J&CA also recently completed a prestressed 600,000 gallon tank for the Town. The Currant Way tank is buried and located just off of Eagle’s Nest golf course. The faux rock hatch design allows the tank to blend into the mountainous landscaping of the neighborhood.

City of Arvada, Arvada, COThe City of Arvada, CO required a 10 Million Gallon Treated Water Storage Reservoir. Note that the top of this tank is being utilized as a recreational area. Four full-size tennis courts, one tennis backboard practice court, and one combined basketball and volley-ball area are provided for area residents. There are also planters for small trees on top of this tank. The prestressed concrete roof of the reservoir serves as the finished playing surface.

Because of these recreational amenities, local residents dropped their objections to a water tank being constructed in their neighborhood. After completion of the tank, the neighborhood continued to develop with luxury homes. One family sold their home across the street from the tank site when they heard a tank would be built there. A few years after the tank was completed their former house came back on the market and they bought it back again!

A second 10 MG Treated Water Storage Reservoir was constructed in Hackberry Hill with the same recreational aesthetic requirements for the top of the hill. The former City Manager, Craig Kocian, has recently stated that these tanks are the best ones in the City.

Green Mountain Water & Sanitation DistrictWith the redevelopment of the Denver Federal Center property, Green Mountain Water and Sanitation District saw a dramatic increase in water demand within the Pink Zone, due largely to the construction of St. Anthony’s Hospital and RTD facilities. Many upgrades to the water system were required, including the addition of a 1 MG buried water storage tank. The tank was constructed of post-tensioned concrete and located on the Warren Tech campus. Construction was completed in 2012.

City of Lafayette, COMME developed master plans for the City of Lafayette’s potable water distribution system. The engineers of MME, J&CA and CTL/Thompson designed a 4.0 MG under-ground, post-tensioned concrete water storage tank to service the City of Lafayette. The City was in need of more total water storage to service its residents. Construction of the tank began in the fall of 1999, and was completed in the summer of 2000. The new tank was built at a site adjacent to the water treatment plant and is gravity fed.

5.0 & 1.75 MG Tank, Consolidated Mutual Water Company, North Table Mountain, Golden, COHorizontal and vertical post-tensioned; buried; post-tensioned roof and floor. This is a “tank-within-a-tank” to enable the water district to operate different sizes of tank in summers and winters.

1.0 MG Tank, Town of Hudson, COAn innovative hybrid design was created and constructed for this 1.0 MG tank. This design has the potential of resulting in a 100-year lifespan for an above grade steel tank. A prestressed concrete floor is married to (using special details) the steel tank walls.

Water & Sewer Rehabilitation; Program ManagementBancroft Clover Water & Sanitation District

Lakewood, Colorado

Merrick & Company provided comprehensive program management including analysis, design, owner’s representation, construction administration, and construction inspection services for the installation of over 42,000 LF of new water lines and 10,000 LF of new sanitary sewer lines within the Bancroft-Clover Water and Sanitation District. The $5.5Million five-year program began in 2005 and was completed in 2010.

Bancroft Water and Sanitation District (BWSD) was formed in 1954 to serve a rural area (now a major segment of Lakewood, CO) immediately west of Denver. Over time this area developed into a major metropolitan suburban area. In 1980, BWSD merged with the Cloverdale Water and Sanitation District to form Bancroft-Clover Water and Sanitation District. Today, the district serves a population of over 95,000 people (50,000 permanent residents and 40,000 daily transient residents). The district’s system includes approximately 110 miles of water lines, 104 miles of sewer lines, 9000 taps, four pump stations, eight pressure zones, five pressure reducing valves with vaults (PRV’s), and fifteen interconnections with the Denver Water system.

Initially, Merrick prepared a condition assessment and a masterplan study and determined that numerous water lines and sewer lines within the district were in need of replacement or upsizing. Merrick recommended a phased (5-year) program of improvements to bring the district’s water and sewer lines to current standards. This program included installing additional lines and replacing undersized lines with larger lines throughout the district.

Subsequently, Merrick provided the design of these upgrades and oversaw the implementation of this 5-year program. New water lines included PVC pipe materials (water and sewer lines) and ductile iron pipe materials (for water lines). Merrick also designed numerous slip-lining rehabilitation installations as part of this program.

● 42,000 LF of new water lines (6”, 8”, 10”, 12” and 16” in diameter) ● 10,000 LF of new sewer lines (8”, 10” and 12” in diameter) ● 10,000 LF of slip line installations for sewer line rehabilitations ● Upgrades to two pump stations

As part of this work, Merrick provided consulting to create and implement a new GIS system for the district. This system includes the results of the condition assessments and the new as-built information on completed repair, reconstruction, and replacement projects. Other relevant system information; such as the age, service history, and future scheduled inspections, repairs, or maintenance; was also entered into the GIS database.CONTACT INFORMATION:
