A unitary or modular, pre-cast, drive-down pit system suitable for use in a heavy equipment wash installation. The completed pit collects runoff generated by the washing of heavy equipment such as construction, industrial, farming, or road-building equipment. The pre-cast concrete separation unit and separate wall sections have tongue and groove mating ends that facilitate assembling the pit and provide for sealing against leakage of water. The separation unit has up to four chambers: a primary solids collection section; a secondary solids settling chamber; a free oil separating section; and a pump water holding section.

We claim: 1. A pre-cast, modular, drive-down pit system for water separation, comprising: a pre-cast water separation unit comprising: opposing sidewalls having forward ends; a floor coextensive with said sidewalls and having a forward end; said floor having a bottom surface; a front wall extending between said sidewalls and spaced rearward of said sidewall forward ends; an intermediate wall extending between said sidewalls and spaced rearward of said front wall; a rear wall extending between said sidewalls and spaced rearward of said intermediate wall; said sidewalls, said floor and said front wall defining a primary solids separation section; said sidewalls, said floor, said front wall and said intermediate wall defining a secondary separation section; said front wall defining a cutout dam for flow of water from said primary solids separation section to said secondary solids separation section; said sidewalls, said floor, said intermediate wall and said rear wall defining an oil and water separation and pump water collection section; said intermediate wall defining a cutout dam for flow of water from said secondary solids separation section to said oil and water separation and pump water collection section; opposing pre-cast pit wall units having forward ends and rear ends; said opposing pit wall units being connectable at their rear ends with respective said forward ends of said sidewalls of said water separation unit, said opposing pit wall units defining a drive-down ramp section; apparatus for lifting said pre-cast, modular, drive-down pit system, said apparatus mounted on said opposing side walls; and an array of protuberances formed on said opposing side walls and wherein said apparatus for lifting is mounted at said array of protuberances. 2. The system of claim 1, wherein said apparatus for lifting includes a pair of lift braces mounted on said opposing side walls. 3. The system of claim 2, wherein each lift brace has a first end and a second end and wherein a respective L-shaped plate is attached at each first end and each second end. 4. The system of claim 1, including a safety rail system mounted on selected walls of said pre-cast, modular, drive-down pit system, said safety rail system having ends attached to steel plates and wherein said steel plates are embedded in said selected walls. 5. A pre-cast modular, drive-down pit system for water separation, comprising: a pre-cast water separation unit comprising: opposing sidewalls having forward ends; a floor coextensive with said sidewalls and having a forward end; said floor having a bottom surface; a front wall extending between said sidewalls and spaced rearward of said sidewall forward ends; an intermediate wall extending between said sidewalls and spaced rearward of said front wall; a rear wall extending between said sidewalls and spaced rearward of said intermediate wall; said sidewalls, said floor and said front wall defining a primary solids separation section; said sidewalls, said floor, said front wall and said intermediate wall defining a secondary separation section; said front wall defining a cutout dam for flow of water from said primary solids separation section to said secondary solids separation section; said sidewalls, said floor, said intermediate wall and said rear wall defining an oil and water separation and pump water collection section; said intermediate wall defining a cutout dam for flow of water from said secondary solids separation section to said oil and water separation and pump water collection section; opposing pre-cast pit wall units having forward ends and rear ends; said opposing pit wall units being connectable at their rear ends with respective said forward ends of said sidewalls of said water separation unit, said opposing pit wall units defining a drive-down ramp section; and an array of protuberances formed on said opposing side walls and a pair of lift braces mounted on said opposing side walls at said array of protuberances for lifting said pre-cast, modular, drive-down pit system. 6. The system of claim 5, wherein each lift brace has a first end and a second end and wherein a respective L-shaped plate is attached at each first end and each second end and wherein each L-shaped plate has a horizontal part disposed on a respective one of said array of protuberances. 7. The system of claim 6, wherein each horizontal part has an opening therein, wherein a respective rod is disposed through each respective opening. 8. The system of claim 7, wherein each respective rod has an upper end and a lower end, wherein each upper end terminates in an eyebolt and each lower end is embedded in a respective protuberance. 9. The system of claim 8 further including a respective array of rebars embedded in each protuberance and surrounding each lower end of each respective rod. 10. A pre-cast, modular, drive-down pit system for water separation, comprising: a pre-cast water separation unit comprising: opposing sidewalls having forward ends; a floor coextensive with said sidewalls and having a forward end, said floor having a bottom surface; an array of weight reduction cells formed on said bottom surface; a front wall extending between said sidewalls and spaced rearward of said sidewall forward ends; an intermediate wall extending between said sidewalls and spaced rearward of said front wall; a rear wall extending between said sidewalls and spaced rearward of said intermediate wall; said sidewalls, said floor and said front wall defining a primary solids separation section; said sidewalls, said floor, said front wall and said intermediate wall defining a secondary separation section; said front wall defining a cutout dam for flow of water from said primary solids separation section to said secondary solids separation section; said sidewalls, said floor, said intermediate wall and said rear wall defining an oil and water separation and pump water collection section; said intermediate wall defining a cutout dam for flow of water from said secondary solids separation section to said oil and water separation and pump water collection section; opposing pre-cast pit wall units having forward ends and rear ends; said opposing pit wall units being connectable at their rear ends with respective said forward ends of said sidewalls of said water separation unit, said opposing pit wall units defining a drive-down ramp section; apparatus for lifting said pre-cast, modular, drive-down pit system, said apparatus including a pair of lift braces mounted on said opposing side walls; an array of protuberances formed on said opposing sidewalls, said pair of lift braces being mounted on said array of protuberances; pre-formed openings disposed in selected ones of said sidewalls, said front wall, said rear wall and said intermediate wall; and knock out plugs closing said openings in said pre-formed openings. 11. The system of claim 10, wherein each lift brace has a first end and a second end and wherein a respective L-shaped plate is attached at each first end and each second end and wherein each L-shaped plate has a horizontal part disposed on a respective one of said array of protuberances. 12. The system of claim 11, wherein each horizontal part has an opening therein, and wherein a respective rod is disposed through each respective opening. 13. The system of claim 12, wherein each respective rod has an upper end and a lower end, wherein each upper end terminates in an eyebolt and each lower end is embedded in a respective protuberance. 14.
